Below are responses to questions for clarifications that may require additional information and/or are not addressed directly within the pre-selection contract documents: Q2-1: To allow videotaping of our training sessions, [MFSS] requires agreement on the following: 1) [MFSS] shall have the right to review and approve the video before it is used; 2) [MFSS] retains proprietary rights to all information contained in the videotape; 3) Customer has the right to use and disclose to its employees the information contained in the videotape for the limited purpose of operating and maintaining the Seller supplied equipment and no other purpose. 4) If the content of the videotape is altered in any way, and such alterations result in personal injury or property damage due to adherence to the altered information, Seller shall have no liability for any such injury or damage. 5) Viewing of the video in isolation does not ensure competent operation of the plant equipment and serves only as a training aid in support of wider customer and industry best practices for safe operation and maintenance of such equipment. Any videotaping of Manufacturer's Training will need to comply the Manufacturer's videotaping requirements including the possible prohibition of videotaping. R2-1: Include requirement as a clarification in the submitted proposal. Q2-2: Please confirm that Manufacturer's Training is required for the Owner's personnel. [MFSS] will unlock portions of the code, such as I/O, to allow the Owner the ability to edit/modify areas of the code. The [MFSS] IP portions of the code locked so that the Owner cannot edit/modify these portions. Any Owner edits/modifications that result in changes to the system performance/operation will void [MFSS]’s performance warranty. R2-2: Confirmed that Manufacturer's Training is required for the Owner's personnel. Include code protection requirement as a clarification in the proposal." Q2-3: In reference to 40 70 00 paragraph 2.3-A.1.a, please allow the use of IFM Efector SD1540 Dispersion Type Flow Transmitters for Air Flow. R2-3: The IFM Efector transmitter will be considered as an approved equal and approved if it meets the specified performance criteria. Q2-4: MFSS provides isolation ball valves for all PIT's used for pressure monitoring. Where PIT's are used for monitoring tank level, the PIT is installed directly to the tank. Please allow the MFSS's standard. R2-4: Provide instrument isolation valves on all pressure instruments, including directly on the tank. Q2-5: Please provide a Plant Hydraulic Profile. What, if any, post membrane system treatment processes exist between the membrane system and the Clearwell? What are the static and dynamic losses between the membrane system and the Clearwell? R2-5: Preliminary Plant Hydraulic Profile is shared in this addendum as a new Appendix B. No treatment process will exist between the membranes and the Clearwell. Refer to preliminary Plant Hydraulic Profile for estimated status and dynamic losses. Q2-6: We noticed there was not a devoted section for electrical specifications. We typically find this in Division 26. Is there any other electrical information available for this project? CPN 105176 Eagle Mountain Water Treatment ADDENDUM NO. 2 Plant Phase IV Expansion – Membrane Filtration ATTACHMENT A A-2 2 of 7 R2-6: Electrical provisions required for the MFSS-provided equipment is included in each equipment specification as well as 40 05 93.23 “Low-Voltage Motor Requirements for Process Equipment.” If there are specific questions, please provide through Bonfire. Q2-7: Please confirm the UF train redundancy requirements for this project. For example, is firm capacity N-1 required for both 35 and 50 MGD? R2-7: There is no requirement for mechanical redundancy for the membrane skids themselves. The proposed system needs to produce 35 MGD on a day where no CIPs are performed, without exceeding the maximum instantaneous design flux. Q2-8: Please confirm the applicable design temperature for the proposed rated capacity of the UF system; can we assume 20 deg C as the design temperature? R2-8: Confirmed – use 20 deg C as the design temperature. Q2-9: Please confirm the intent of the full-scale treatment system is to direct the UF BW wastewater to a backwash recovery basin and ultimately have the supernatant routed to the head of the pretreatment system as shown in p.1472 of the specification. If so, what is the intended maximum proportion of BW wastewater to be blended with the raw feed water? During the pilot phase, was BW wastewater recycle implemented and, if so, for what duration? R2-9: Confirmed - the backwash wastewater will be sent to a settled water tank where it will be combined with backwash waste from the BAFs, settled, and routed back to the head of the plant. The maximum proportion of UF backwash waste that will be allowed to be recycled will be 10% of daily Net Filtered Water. This process flow could not be modeled in the pilot as the source water was effluent from the existing EMWTP full-scale plant which includes the same process flow as EMWTP Phase IV, except it does not use a membrane filtration system. However, this process including a membrane filtration system has been operating since 2009 at the Westside Water Treatment Plant, also operated by the City of Fort Worth, and withdrawing water from a similar source. It is up to the MFSS to determine a stable operating flux for the proposed plant based on this information. Q2-10: Please confirm if neutralized CIP waste is also intended to be recycled to the head of the pretreatment system. R2-10: Neutralized chemical waste from both CIPs and CEBs will be sent to the sanitary sewer connection and not to the backwash recovery system. Q2-11: Please confirm TCEQ’s position regarding the VCF impact on LRV calculations by routing BW waste to the head of the treatment plant. R2-11: To our knowledge, there is no VCF impact to the proposed process configuration. The EPA Membrane Filtration Guidance Manual only assesses VCF in connection with the degree of concentration at the surface of the membrane based on the hydraulic configuration of the membrane system itself, not upstream or downstream processes. The proposed process flow would have two settling steps (one at the settled water tank and another at the floc/sed basin) and one filtration step at the BAFs. The proposed process has operated at the Westside Treatment Plant since 2009 and to our knowledge there is no VCF penalty used in the integrity test calculation at that plant. CPN 105176 Eagle Mountain Water Treatment ADDENDUM NO. 2 Plant Phase IV Expansion – Membrane Filtration ATTACHMENT A A-2 3 of 7 Q2-12: Are there any layout and/or dimensional restrictions applicable to the MFSS with regards to the UF trains and ancillary systems? R2-12: Please see attached drawing indicating an available space for the membrane mechanical equipment. Q2-13: Please confirm that the specified capacity is based on an assumed MIT frequency of once every 24 hours per train. R2-13: A daily Pressure Decay Test/Direct Integrity Test (DIT) is required. It is incumbent on each proposer to ensure that the maximum instantaneous flux as specified in Section 46 61 33, 2.3 A.2 is not exceeded to produce the specified flows on non-CIP days. Q2-14: Please see an additional request to remove the use of PVC in the drinking water process. It is well known in the world PVC is very dangerous in drinking water piping and the City and their citizens should be protected. Please delete 46 61 33 - 18, N. Piping Systems:, 4. PVC Pipe and Fittings:. This should include all pipes used in the drinking water process exception from the chemical cleaning system pipping. This should also be for the requirement of the membrane filter module. Our design and module as no PVC or UPVC materials in contact with the drinking water for the lowest risk solution for our customers. We will not knowingly risk our customers health. If this is not deleted to allow us to bid please release a letter prior to the bid date executed from the City accepting the risks of using PVC or UPVC in contact with their drinking water process. From the USA Today link below. Enck said the report raises legitimate concerns about the health consequences from chemicals in PVC pipes leaching into the drinking water. New report warns against using PVC pipes in drinking water systems (usatoday.com) https://www.usatoday.com/story/news/investigations/2023/04/18/new-report-warns-against-using- pvc-pipes-drinking-water-systems/11688737002/ R2-14: No change. Q2-15: Please provide a Plant Hydraulic Profile. What are the static and dynamic losses between the membrane system and the washwater recovery tanks? R2-15: This portion of the design has not been finalized. Assume a head requirements of 10 psi for backwash pump sizing. Q2-16: The $95,000.00 allotted for Special Engineering Services is considerably lower than the cost of providing these services as described in Section 00 52 43 such that it would be a loss to the MFSS in the event an award is not made for the Membrane Filtration System. As the Contract Price can be adjusted by amendment or change order (Article 3), we request that Proposers are allowed to enter their full price for the Special Engineering Services to be included in the Total Present Worth Cost for evaluation. R2-16: Allotted price for Special Engineering Services will not be modified. Q2-17: Is a prebid meeting sign in sheet available? R2-17: This was provided as an attachment in Addendum No. 1 Q2-18: To confirm, N+1 redundancy is only required on ancillary equipment and not the membrane treatment trains themselves? I.E pumps, pre-strainers, compressors, should be N+1, but the UF skids will be N+0. R2-18: Confirmed. CPN 105176 Eagle Mountain Water Treatment ADDENDUM NO. 2 Plant Phase IV Expansion – Membrane Filtration ATTACHMENT A A-2 4 of 7 Q2-19: [MFSS] typically requires that the warranty period start after modules are placed in operation or six (6) months after shipment from the Toray facility, whichever occurs first. Please consider modifying this clause to match Toray’s requirements. R2-19: No change. Q2-20: Although stainless steel piping is an NSF compliant material, NSF certification (61,372) is often unavailable for fabricated piping. Please confirm if this is acceptable. R2-20: Confirmed that this is acceptable as long as fabrication of pipe and fittings is from certified piping. Q2-21: Please confirm in lug style valves for all sizes is acceptable. R2-21: Lugged valves are acceptable for all sizes. Q2-22: For the future design capacity of 50 MGD, this Section requires: "Future Design Capacity: Piping, pumping, backwash equipment, CIP equipment, air equipment, integrity test equipment supplied for a future design capacity". In the Pre-Bid Conference Call there was a requirement to provide a narrative of the additional equipment (backwash, CIP, etc.) to meet the future the 50 MGD future capacity. Is the MFSS to supply the necessary ancillary equipment for 50 MGD so that only additional membrane trains and modules are needed or will additional ancillary equipment be provided with the expansion to 50 MGD. R2-22: Ancillary equipment may be added in future expansion. Q2-23: MFSS interprets this to require that the MFSS provide 3D drawings of off-skid plant piping. This is typically outside of the scope of supply of the MFSS. Please confirm that the off-skid 3D piping drawings are to be supplied by the City's Engineer. R2-23: MFSS to provide 3D showing interconnecting piping or add as a clarification that it is not included if they are not able to provide. Q2-24: Please confirm that these coagulants are used in the pretreatment system and that the membrane system will not be operated in a direct coagulation mode. R2-24: Coagulants will be used in the pre-treatment system and not direct. Q2-25: Per Attachment A, response to Q1-34 - Requirement applies to the party doing the programming of the membrane system. MFSS interprets this response to mean that the MFSS is to have a Service Center within 200 miles of Fort Worth. Per Attachment B 1-I Section 40 61 00 Paragraph 1.9.E I Delete paragraph. These appear to be conflicting responses. Which response governs? R2-25: Refer to updated wording in paragraph 1.9-D in 40 61 00 in the reissued specifications in Addendum No.1. Disregard response to Q1-34, as that paragraph has been deleted. Q2-26: [PID-2] indicates that the VFD’s/motor starters required for the pre-strainers are in the MFSS Master Control Panel. These are generally outside of the MFSS’s scope of supply and are located in a separate MCC. Please confirm if motor starters for the pre-strainers are in the MFSS’s scope. R2-26: MFSS is required to supply as the intent is for motor starter to be supplied with strainers. They do not need to be housed in the control panel and may be shipped loose for installation by the Contractor in the MCC. Q2-27: The double block and bleed valves shown in this P&ID, do not include a pneumatic actuator for the outer block valve. [MFSS] recommends that these “outer” valves also be pneumatic to avoid manual valve operation during MC and CIP sequences. CPN 105176 Eagle Mountain Water Treatment ADDENDUM NO. 2 Plant Phase IV Expansion – Membrane Filtration ATTACHMENT A A-2 5 of 7 R2-27: It is acceptable to propose outer valves to be pneumatic. Q2-28: Please confirm that variable filtration flow is acceptable as trains leave production for offline events such as backwash, chemical cleaning, MIT. R2-28: Confirmed. Q2-29: Please advise if RTP-1 certification is truly required for FRP tanks. This tends to add cost and extend leads times if it is required. R2-29: RTP-1 certification is required. Q2-30: Please clarify if ANSI B73.1 pumps are required or if any close coupled or bearing frame end suction pumps (e.g. Goulds 3656 or Goulds 3756) are acceptable. R2-30: If horizontal end suction pumps are provided, compliance with ANSI B73.1 is required. Q2-31: The P&ID depicts diaphragm valves, Section 46 61 33 - 2.2.J.13.c states: "Use vented ball valves on hypochlorite feed lines." Which type of valves are to be used? R2-31: For sodium hypochlorite service, either diaphragm or vented ball valves are acceptable. Q2-32: For the future design capacity of 50 MGD, this Section requires: "Future Design Capacity: Piping, pumping, backwash equipment, CIP equipment, air equipment, integrity test equipment supplied for a future design capacity". In the Pre-Bid Conference Call there was a requirement to provide a narrative of the additional equipment (backwash, CIP, etc.) to meet the future the 50 MGD future capacity. Is the MFSS to supply the necessary ancillary equipment for 50 MGD so that only additional membrane trains and modules are needed or will additional ancillary equipment be provided with the expansion to 50 MGD. R2-32: Additional auxiliary equipment may be added with the expansion. Q2-33: Please confirm if valve mounted solenoids are acceptable in lieu of a common solenoid bank (with tubing being routed on-skid to a common manifold). With 316L pneumatic tubing, and limit switches, [MFSS] generally prefers valve mounted solenoids. R2-33: Acceptable. Q2-34: This P&ID indicates that the VFD’s/motor starters required for the CIP/Neutralization pumps are in the MFSS CIP Control Panel. These are generally outside of the MFSS’s scope of supply and are located in a separate MCC. Also, please confirm if heater contactors are in the MFSS’s scope of supply. R2-34: VFDs are in Contractor’s scope and heater contactors are in MFSS’s scope. Q2-35: Per Strainer Manufacturer: "It is not possible to find the moment that screen is exactly 75% blind. The pressure loss across a filter is a function of both filter housing drop (depends on the filter body geometry) and the screen drop. This total pressure drop is exponential and will reach to the DP set point value rapidly at the later part of the curve. So, predicting the pressure drop at 75% screen blind is not that easy." Is this requirement applicable given the water quality downstream of the Bio Filters? If Yes, please provide guidance on how the Strainer Manufacturer is to determine when this occurs. If No, please removed the " 2 psig even when strainer surface media is 75 percent clogged" requirement. R2-35: Normal operating pressure should be consistently less than two psi during normal operating cycles. Please include a 25% safety factor between normal operating pressure and the maximum pressure that would initiate a strainer backwash. CPN 105176 Eagle Mountain Water Treatment ADDENDUM NO. 2 Plant Phase IV Expansion – Membrane Filtration ATTACHMENT A A-2 6 of 7 Q2-36: SWIFT Funding: How does the US Iron and Steel requirements for SWIFT funding differ from AIS requirements? Per EPA Memorandum “Implementation of American Iron and Steel provisions of P.L. 113-76, Consolidated Appropriations Act, 2014” question 22, membrane filtration systems are specifically not considered a construction material for the purposes of the AIS requirement. Accordingly, appurtenances integral and associated with system operation, like valves, are not subject to the AIS requirements as a construction material. Additionally, please confirm if funding requiring BABAA compliance is expected. Unlike AIS, BABAA does not have special provisions/exceptions for water treatment equipment. R2-36: At this point, BABAA compliance would not be required for this project because it is anticipated to be funded through the TWDB’s SWIFT Program, which includes state-level requirements. From the guidance documents, U.S. Iron and Steel requirements align with AIS when it comes to membrane equipment. Please see the snips below from the TWDB’s United States Iron and Steel Guidance for Projects Funded through State Programs (TWDB-1105). See below for TWDB’s guidance document for the SWIFT Program (TWDB-0900) for reference.

Q3-2: RTDs are not included as the motors are already supplied with NC thermostats. Please confirm this is acceptable. R3-2: Motors smaller than 200 HP shall have a form C NC temperature switch. Motors equal to or larger than 200 HP shall have RTDs. Q3-3: Blower Manufacturer's interpretation of the specification that IEEE-841 motors are not required. Therefore, Inpro seals will not be provided with the motors. The motors come with a V ring shaft slinger on both ends and are rated IP55 protection rating. Please confirm this is acceptable. R3-3: All motors shall be IEEE 841 rated. Q3-4: An encoder is not applicable to this application. Therefore, this is not provided. Please confirm this is acceptable. R3-4: Yes, this is acceptable. Q3-5: PFCCs are not applicable, as the motors will be VFD driven. Please confirm this is acceptable. R3-5: Yes, this is acceptable. Q3-6: Per the MFSS's Environmental Health and Safety Department, paint in liquid form is a Hazardous Material. The storage and shipment of Hazardous Materials is prohibited by Company policy. R3-6: Please include mention of this policy in the submittal. Q3-7: Please clarify chemical line plumbing size requirements for each application. MFSS anticipates providing the following: Chemical Suction (in) Discharge (in) Caustic Soda 0.5 0.5 Sodium Hypochlorite 1.5 1 Sodium Bisulfite 0.5 0.5 Citric Acid 1 1 R3-7: MFSS is responsible for designing and sizing a complete chemical system for membrane cleaning. Provide size assumption in the submitted proposal. Q3-8: As per specification, piping, pumping, backwash equipment, CIP equipment, air equipment, integrity test equipment are to be supplied for future design capacity. Are we expected to also provide electrical systems such as PLC, UPS, IOs for future capacity (50 MGD) with phase 1 proposal? R3-8: The MFSS will provide additional future/reserved I/O capacity to include all points that are anticipated for the final build-out of the system (50 MGD). Our goal is that the PLC system will be ready and able to receive the I/O points that are required for additional equipment, instrumentation and other signals that will be required to CPN 105176 Eagle Mountain Water Treatment ADDENDUM NO. 3 Plant Phase IV Expansion – Membrane Filtration ATTACHMENT A A-3 2 of 4 complete the 50 MGD build-out when that happens without requiring hardware changes. Programming software changes to accommodate the additional equipment for future capacity are acceptable. Q3-9: Can the MFSS offer Allen Bradley for PLC in lieu of Modicon – M580 per Section 40 63 43 (p.285)? R3-9: The MFSS provided PLC will be the Modicon M580 with no substitutions allowed. Q3-10: The membrane rack layout (for 50 MGD) provided in addendum 2 is different from what was specified initially (i.e., 40’x160’). Please confirm if the skid dimensions provided initially (i.e., 40’x160’) is acceptable? R3-10: Please use new dimensions provided if possible. Q3-11: Blower Manufacturer does not provide project specific impeller balancing or overspeed test reports. Please confirm that these reports are not required. R3-11: Factory overspeed test reports, not specific for this project, would be sufficient. Q3-12: Replacing the gaskets, seals, O-rings & bearings on the blower stage requires the blower stage to be shipped back to the factory for an overhaul by a Blower Manufacturer trained technician. Please confirm that these spares are not required. R3-12: If this is the case, the spare should still be covered. For example, if the unit is shipped back for the work there should be at least one set of these seals that the City would not be charged for later. Q3-13: Blower Manufacturer's blower local control panels do not have the capability to sequence the blowers. This is performed by the MFSS's MCP. Please confirm this is acceptable. R3-13: This is sufficient. Q3-14: Blower Manufacturer is providing their standard X/Y axis blower vibration sensors which will provide an alarm and fault. This does not indicate which bearing failed. Please confirm this is acceptable. R3-14: One skid-mounted vibration sensor is sufficient. Please request if the manufacturer can provide X/Y/Z axis vibration sensors. It is acceptable for the logic to not indicate which direction failed but rather send back general fault. Q3-15: Blower Manufacturer is providing their standard set of transmitters which will display their readouts on the local control panel, as well as, will fault the blower package should an adverse condition be met. Gauges & switches are redundant and are not provided. Please confirm this is acceptable. R3-15: The differential pressure switch across the inlet filter could be furnished separately by the contractor with logic to alarm with low inlet pressure. Q3-16: Blower Manufacturer is guaranteeing a free field noise level of 78 dBA per ISO-2151 empirical data. Installed sound levels cannot be guaranteed as there are factors outside of the blower manufacturer's scope that can adversely affect installed sound levels (i.e. other machinery running, external piping configuration, facility layout...etc). Please confirm this is acceptable. R3-16: Noted, but the requirement for the free field noise level in the specifications will remain. Q3-17: Vibration sensors are typically not provided for motors of this size and will require a custom built motor. Therefore, Blower Manufacturer is taking exception to the vibration sensors. Blower CPN 105176 Eagle Mountain Water Treatment ADDENDUM NO. 3 Plant Phase IV Expansion – Membrane Filtration ATTACHMENT A A-3 3 of 4 Manufacturer will verify that the blower package is operating at 0.3 IPS RMS or less. Please confirm this is acceptable. R3-17: May provide one common vibration sensor on the blower skid for both the motor and the blower. Note in proposal. Q3-18: An anti-spin backspin device is not applicable to this application. Therefore, this is not provided. Please confirm this is acceptable. R3-18: Correct, this device is not required. Q3-19: Spare Parts - If Qdos series pumps are allowed the only applicable spare parts per 1.7.A will be the following: (1) Replacement Pumphead Cartridge / Pump R3-19: This is sufficient. Q3-20: Please confirm if separate control panels and motor controllers are required. On most peristaltic pumps, separate control panels & motor controllers are not required because all controls are integral to the pumps. R3-20: Integral controls are acceptable. Q3-21: Will Qdos Series pumps be acceptable? R3-21: Yes, they are acceptable. Q3-22: Please confirm if a local junction box is acceptable in lieu of a local control panel. Typically, we terminate all signals into a NEMA 4X FRP junction box. The pump will have an on/off switch. The pump display will show GPH, running status, and alarm conditions. These signals can t hen be used/controlled by SCADA or UF PLC. R3-22: Yes, a local junction box is acceptable. Q3-23: Will socket weld connections for calibrations columns be acceptable? R3-23: Socket weld connections for calibration columns are acceptable. Q3-24: Are backpressure/anti-siphon valves required? They are not included in the P&IDs R3-24: Backpressure valves are required on the discharge. Q3-25: Section 46 61 33 pg 22 Paragraph 2.4.C.13 - Requirement States: Interface seamlessly with the plant SCADA system. Please provide information on the SCADA platform that will be used. R3-25: The MFSS’s control system shall be fully compliant with the Modbus TCP/IP communications protocol and allow for unrestricted full duplex (read and write) communications with the SCADA system. The SCADA system uses a standard OPC-UA server communications driver which fully supports the Modbus TCP/IP protocol to all compliant devices. Additional information for any relevant specific SCADA system details will be provided on an as needed basis to the selected MFSS. Q3-26: We request an additional two (2) weeks to the Deadline For Submissions to July 11th, allowing additional time for engineering review and response by specified suppliers/sub-vendors to the requirements for large and critical components reflecting technical changes and comments per Addenda. R3-26: No change to the schedule. Q3-27: No drawings were included in the specification for review. The door mounted circuit breaker is not included. Please confirm this is acceptable. CPN 105176 Eagle Mountain Water Treatment ADDENDUM NO. 3 Plant Phase IV Expansion – Membrane Filtration ATTACHMENT A A-3 4 of 4 R3-27: A door-mounted circuit breaker is not required for this panel, with the understanding that the VFD is located in the MCC. A local disconnect will be located near the blower, and a 120V circuit breaker will be needed inside the blower panel. Q3-28: Will this form [in 00 45 26] need to be completed as a part of the bid, or will it be signed/filled only after the bid is awarded? R3-28: The MFSS will need to provide a worker’s compensation certificate of coverage to the General Contractor. No need to provide with this proposal, but any associated cost must be covered by the proposal cost included. Q3-29: Performance bonds are typically tied to commercial performance (schedule, delivery of all equipment, materials and workmanship warranty), and not to some of the process performance criteria tested during the facility reliability test. Can a separate Process Performance Guarantee document be provided to cover process related guarantees? R3-29: No change. A Performance Bond covers various aspects of the performance of a contract, including meeting the technical criteria of the project as verified by the Performance Test. It is conventional for a Performance Bond to cover all aspects of performance on a membrane system procurement project. Note that the RFP language already includes a Performance Guarantee in the form of a performance test with penalties for not meeting specified criteria. The required Performance Bond should include coverage from the surety for this commercial obligation.

Membrane Filtration Module Warranty 1. The MFSS warrants that the Membrane Filtration Modules are free from defects in materials and workmanship and shall conform to the requirements of Article 6 of the Proposal Form (including MFSS specified performance values) and Section 466133, of the Specifications solely. For the purposes of this warranty, flow rate per module will be guaranteed at greater than or equal to 45 gpm per module, subject to the following conditions/exclusions: a. Flow guarantees are only applicable when the modules are in a "clean condition." Modules are defined to be in the clean condition when they are free from reversible or irreversible fouling (from any source). WesTech has no control over the exposure of the modules to foulants at any time during the operation of the plant. If there is a failure to meet performance criteria as listed in Article 6, a module flow test followed by module autopsy may be required to confirm membrane module condition. 1) The module flow test will be conducted on a single module with RO permeate water or UF filtrate water (as long as there are no foulants in the UF Filtrate). If the module(s) fail to meet the required flow rate, module(s) will be sent to a third party for a module autopsy. 01 90 00 – 3 WARRANTIES Page 3 of 9 CITY OF FORT WORTH Eagle Mountain WTP – Phase IV Expansion STANDARD CONSTRUCTION SPECIFICATION DOCUMENT Membrane Filtration System Revised 7/01/2011 City Project No. 105176 2) If the module autopsy shows that failure of the module flow test is solely attributable to membrane fiber integrity/pore collapse, and not other factors, replacement of tested modules will be covered by the module warranty herein. b. Daily complete operating logs and data for each operating train showing system parameters including but not limited to feed water turbidity, feed water pH, flow rate, flux rate, permeability, and cleaning intervals, must be provided to show that system has been operating per the requirements set forth by WesTech within the WesTech O&M Manual. In addition, the operating logs shall record any and all plant operational events including but not limited to: (i) system or train start-up dates and time; (ii) system or train shut-down dates and times (with evidence of proper module storage per O&M); (iii) changes in the type, brand or concentration of chemicals or pretreatment configurations used (with proof of WesTech approval); (iv) the dates when the modules were chemically cleaned as well as the chemical concentration, type, and procedure used. c. Failure to meet flow capacity requirement must be solely attributable to membrane fiber integrity/pore collapse, and not other factors including but not limited to reversible or irreversible fouling, feed water quality outside of values provided herein, or operating the system outside of recommended operating ranges. This will be verified via a third party module autopsy. d. WesTech/Toray reserve the right to approve the test unit. 2. The MFSS’s Membrane Filtration Module Warranty period shall commence at Substantial Completion (Beneficial use by Owner) and continue until the end of the pro-rata warranty period. The Membrane Filtration Module Warranty shall consist of two parts: 1) a Full Replacement Period, and 2) a Pro-Rata Period. The Pro-Rata calculation of Membrane Filtration Module Price shall begin with the Pro-Rata period, after the conclusion of the Full Replacement Period. The Membrane Filtration Module Warranty period shall exist as a contractual obligation between the MFSS and Owner. A renewable Warranty Bond or Letter of Credit shall be provided for the Membrane Module Warranty period. The amount of the Warranty Bond or letter of Credit shall be in the amount that is included in Item A of the Proposal Form. a. Full Replacement Period 1) The Full Replacement Period shall last for 60 months after the date of Substantial Completion following successful demonstration testing of the Membrane Systems. 2) Contractor and Supplier shall record and maintain records of the date of installation for membrane modules. b. Pro-Rata Period 1) The Pro-Rata Period shall commence with the end of the Full Replacement Period and last for a period of 60 months after the Full Replacement Period.

(APAI) to conduct a membrane filtration pilot study at the Eagle Mountain Water Treatment Plant (EMWTP) from November 4, 2014 through February 25, 2015. The purpose of the pilot study was to evaluate membrane filtration for a future 35 million gallon per day (MGD) capacity expansion at the EMWTP. After a request for information process, BASF, Dow, Pentair, and Toray were selected to participate in the pilot study. Dow, Pentair, and Toray each partnered with an original equipment manufacturer (OEM) to furnish pilot systems for the study, and BASF provided its own unit. The study assessed membrane performance downstream of a pretreatment scheme that included ozonation, coagulation, flocculation, sedimentation, and biologically active filtration (BAF). Ferric sulfate and polyaluminum chloride (PACl) coagulants were evaluated during the study. The purpose of this pilot study report is to document the pilot study results for review and approval by the Texas Commission on Environmental Quality (TCEQ) and for use by the City during the design for the planned EMWTP expansion. The four membrane vendors completed the pilot study using PACL and BAF pretreatment in accordance with the pilot study protocol approved by the Texas Commission on Environmental Quality (TCEQ). APAI has used the pilot study results to develop net filtrate capacity requests for each membrane. If the requests are approved by the TCEQ, the four vendors may be considered for the future EMWTP expansion. Table 1 provides an overview of the pilot study including the net filtrate capacities that are being requested for each of the membranes. As shown in Table 1, Dow operated at the highest net filtrate capacity and Toray operated at the highest filtrate flux and recovery. The sustained system runtimes achieved during the study provided a robust data set for evaluating the membrane systems. After reviewing the pilot study results, APAI has determined that Dow and Toray satisfied the performance criteria for the pilot study; whereas, BASF and Pentair satisfied five of the seven criteria. The BASF and Pentair membranes experienced multiple fouling events characterized by transmembrane pressure (TMP) values that approached or exceeded the vendor recommended filtration TMP limit. In order for BASF and Pentair to sustain their instantaneous flux rates, chemically enhanced backwashes would have been required at a more frequent interval than the once per day frequency defined by the performance criteria yielding a recovery of less than the minimum 95 percent. Membrane permeability loss was also assessed as part of the pilot study protocol. BASF, Pentair, and Toray reported no permeability loss; whereas, Dow reported a permeability loss of approximately 6.1%. Additional details on membrane performance and pilot study results are provided within the body of this report and the Appendix. APAI recommends that both the pilot study results and full-scale operating history of each vendor be considered when determining safety factors for the full-scale design of the future EMWTP expansion.

The purpose of the pilot test is to evaluate the performance of BASF, Dow, Pentair, and Toray membranes for the filtration of Eagle Mountain Lake surface water, to satisfy TCEQ testing requirements, and to facilitate the development of design criteria for a planned future expansion of the EMWTP to add a membrane filtration system with up to 35 MGD of net filtration capacity (possibly in phases). The EMWTP pilot study compliments a pilot study conducted by the City in collaboration with the Cities of Mansfield, Waxahachie, and Midlothian in 2007. The 2007 study evaluated the performance of multiple membrane vendors, including Evoqua Memcor (then Siemens Memcor), GE ZENON, and Pall Corporation, for the treatment of the Tarrant Regional Water District (TRWD) supply. In 2014, the TCEQ granted a request to approve the previous Pall Corporation pilot study results for use at the EMWTP. The present study seeks to add additional vendors to the list of vendors eligible to participate in the planned expansion. The EMWTP pilot study was conducted from November 4, 2014 to February 25, 2015 and evaluated the BASF dizzer XL 0.9 MB 70 WT, Dow IntegraFlow DW102-1100, Pentair Aquaflex 55 UFC-LE, and Toray HFU-2020N UF membrane modules. The membranes were installed on automated pilot systems. Dow partnered with Wigen Water Technologies, Pentair partnered with Harn R/O Systems, and Toray partnered with WesTech Engineering to furnish pilot equipment. BASF supplied their own pilot system. The pilot study evaluated membrane performance downstream of a pretreatment scheme that included ozonation, coagulation, flocculation, sedimentation, and biological filtration. Ferric sulfate and PACl coagulants were tested during the study.

The objectives are listed below along with a discussion of how each objective was achieved. Objective 1: Determine design flux, recovery, chemically enhanced backwash (CEB) frequency and regime, chemical clean-in-place (CIP) frequency and regime, chemical usage, electrical usage, as well as other design parameters for full-scale process design The pilot study tested flux, recovery, system operating parameters, CEB protocols, and CIP protocols to provide information for the future full-scale system design. The tested values, procedures and resulting process data are documented within this pilot study report. The performance of each membrane vendor varied during the pilot study, and APAI recommends that both pilot study results and full-scale operating history be considered when determining safety factors for full-scale design parameters (i.e. design flux, cleaning interval, etc.). Objective 2: Identify multiple successful membrane vendors as evaluated on the basis of demonstrated flux, recovery, backwash frequency, chemical cleaning frequency, and other considerations The four membrane vendors completed the pilot study. If approved by the TCEQ, the four vendors may be considered for the future full-scale EMWTP expansion. Objective 3: Evaluate BAF filtered water as a feed water source BAF filtered water was evaluated as a membrane feed water source during the pilot study. The four vendors completed the pilot study protocol using BAF pretreatment. Membrane performance varied between vendors. Objective 4: Evaluate ferric sulfate and PACl as coagulants and select a preferred coagulant for full-scale operations Ferric sulfate and PACl coagulants were evaluated during the study. After partial completion of the ferric sulfate testing, the City decided to switch from ferric sulfate to PACl coagulant in accordance with their desired long term operating strategy for the EMWTP. Prior to switching coagulants, each membrane vendor was consulted, and the four vendors noted that they would prefer PACl over ferric sulfate. The four vendors completed the pilot study protocol using PACl pretreatment. Membrane performance varied between vendors. Objective 5: Satisfy TCEQ pilot testing requirements The pilot study was conducted in accordance with the approved pilot study protocol (refer to Appendix G) and TCEQ review comments (refer to Appendix F). The pilot protocol incorporated TCEQ Stages 1, 2, and 3 as originally outlined in the now expired Public Drinking Water program staff guidance titled “Review of Pilot Study Reports for Membrane Filtration” (refer to Appendix K). Eagle Mountain Water Treatment Plant Membrane Pilot Study Report (Draft) Alan Plummer Associates, Inc. 5 F:\projects\0318\054-01\Doc\Report\Draft\Draft Pilot Study Report_City Review\2015-07-21_Eagle Mountain WTP_Membrane Pilot Study Report (DRAFT).docx Objective 6: Determine design criteria for ancillary systems such as chemical feed and clean-in- place (CIP) systems The pilot study tested flux, recovery, system operating parameters, CEB protocols, and CIP protocols to provide information for the future full-scale system design. The tested values, procedures and resulting process data are documented within this pilot study report. APAI recommends that both pilot study results and full-scale operating history be considered when determining safety factors for full-scale ancillary system design criteria (i.e. chemical storage, chemical feed pumps, etc.). Objective 7: Identify potential fouling issues and develop mitigation or cleaning solutions The BASF and Pentair membranes experienced multiple fouling events characterized by TMP values that approached or exceeded the vendor recommended filtration TMP limit. While the pilot study results indicate that the membranes recovered permeability after CIPs, a CEB interval of once per day was not sufficient to promote stable performance at the instantaneous flux rates selected by the vendors. Accordingly, APAI has assumed a CEB interval of two CEB events per day to complete net filtrate capacity calculations and to evaluate the BASF and Pentair membranes relative to the performance criteria. The intent of the increased CEB frequency is to acknowledge the need for additional chemical maintenance to manage fouling. The design CEB frequency may differ from the frequency used to complete the pilot study evaluation. APAI recommends considering the implications of filtration TMP, chemical maintenance frequency, pilot-study results, and full-scale installation history when selecting full- scale design criteria. The pilot study protocol included a required CIP as part of PACl pretreatment testing. Dow reported a permeability loss of 6.1-percent following the required CIP. APAI recommends considering the implications of Dow module permeability loss when selecting full-scale design criteria. Fouling issues were not observed with the Toray module during the pilot study. Objective 8: Familiarize staff with the operation and maintenance of the membrane process equipment and ancillary equipment City of Fort Worth staff, including operations, maintenance, electrical and instrumentation personnel, were able to interact directly with the pilot equipment and become familiar with membrane filtration systems. The membrane vendors, OEMs, and APAI provided training at the start of the study to inform City staff on operations and maintenance procedures. APAI also prepared quick reference user’s guides for each pilot system to familiarize the City staff with operations and maintenance efforts. The knowledge, diligence, and proactive participation of City staff during the study were integral to the successful completion of the study.

The four pilot systems treated BAF filtered water as depicted in Figure 3. Each pilot unit was equipped with flow meter(s) as well as sample taps for water quality sampling. Process and instrumentation diagrams showing the locations of flow meters and water quality instruments are provided within each vendor report in Appendices A through D. Figure 3: EMWTP Process Flow Diagram 4.2.1 Pretreatment Chemical Dosing The coagulant and ozone doses recorded during the pilot study are provided in Figure 4 and Figure 5, respectively. Ferric sulfate was dosed as a pretreatment coagulant until December 3, 2014 when the EMWTP switched to PACl coagulant. Table 5 provides ozone disinfectant summary information for the UF pilot filtrate samples. The ozone residual is sampled as part of full-scale EMWTP operations at the ozone contactors. Ozone residual was not measured in the membrane pilot feed, because the ozone residual in the BAF filtered water would be non-detect. 1 Polymer feed upstream of the membrane pilot systems was discontinued during the study with the exception of a few short duration polymer feed events.

During the pilot study, ferric sulfate and PACl coagulants were evaluated as membrane pretreatment chemicals. Per the pilot study protocol (refer to Appendix G), each coagulant was to be evaluated independently using TCEQ testing Stages 1, 2, and 3. Ferric sulfate Stages 2 and 3 were canceled following discussions between the City, APAI, and membrane vendors, and each vendor was given the option to conduct a CIP prior to the official start of PACl testing. Two optional CIPs were scheduled during the pilot study along with one required CIP following PACl Stage 5 (TCEQ Stage 2) testing.

Each vendor prepared a detailed report to document the performance of their membrane in accordance with pilot protocol requirements. The reports were submitted to APAI for review and the revised versions are included in Appendices A through D. At a minimum, each vendor report contains the information outlined in Table 10. As part of the review process, APAI performed an independent analysis of the raw pilot study data received from each vendor. Process data trends for each membrane are provided in Section 6.1. The performance trends represented in the APAI analysis are in agreement with the vendor reports. Issues identified during the pilot study related to the technical completion of the study are documented in Section 6.5 along with the corrective actions taken to address these issues.

Supplemental information for Table 12 is provided below: ANSI/NSF Standard 60 documentation for CIP chemicals is provided in Appendix J. The quantity of filtrate consumed during CIPs and the chemical waste disposal method for the full-scale system may not correlate to the pilot-scale system and should be determined during full-scale system design. Pilot system waste streams were sent to the EMWTP backwash recovery basins. BASF, Dow, and Toray recommended CIP intervals of 60 days, 90 days, and 120 through 180 days, respectively. Pentair recommended that daily CEBs substitute for CIPs. The pilot study data does not necessarily substantiate the vendor recommended CIP frequencies. APAI recommends evaluating pilot study results and full-scale installation history prior to setting a design CIP frequency for the full-scale system.

Since membrane pilot units periodically record data during operating periods other than steady-state filtration (i.e. backwashes, maintenance washes, transitions), APAI applied filters to the data in its analysis to exclude data that are not representative of active filtration. Descriptions of the data filters applied to each data set are provided in Table 13. The membrane process data performance trends for the BASF, Dow, Pentair, and Toray membrane systems are presented in Figure 8 through Figure 11. Each graph presents trends for feed temperature, TMP, filtrate flux, filtrate flux at 20°C, and specific flux at 20°C. The graphs cover the pilot study from the start of Stage 1 to the conclusion of Stage 6. Filtrate turbidity results for the four membrane vendors, reported at either 4-minute or 5-minute intervals, are provided in Figure 12 through Figure 15. Unfiltered pilot study data shall be provided to the TCEQ as a supplement to the pilot study submittal. Table 13: Description of Data Filters Applied to APAI Data Analysis Vendor Data Filter Description BASF The BASF pilot periodically recorded data prior to achieving steady-state filtration. APAI applied the following data filter to report only the data associated with steady-state filtration: Exclude data corresponding to flow values outside the range of the average flow +/- 3 standard deviations The BASF pilot reported data on a more frequent interval than 5 minutes. The data set is filtered to report data at 5 minute intervals. Dow The Dow pilot periodically recorded data prior to achieving steady-state filtration resulting in the recording of erroneous TMP data. APAI applied the following data filter to report only the data associated with steady-state filtration: Exclude data corresponding to TMP values that are less than the TMP of a new, clean membrane The Dow pilot recorded data at 10 minute intervals until February 6, 2015. Thereafter, the pilot recorded data at 2 minute intervals. The data set is filtered to report the data collected after February 6, 2015 at 4 minute intervals. Pentair The Pentair pilot periodically recorded data when the filtrate flow registered a value of 0. APAI applied the following data filter to report only the data associated with steady-state filtration: Exclude data corresponding to a filtrate flow of 0 The Pentair pilot reported data at 2 minute intervals. The data set is filtered to report data at 4 minute intervals. Toray The Toray pilot periodically recorded data prior to achieving steady-state filtration. APAI applied the following data filter to report only the data associated with steady-state filtration: Exclude data corresponding to flow values outside the range of the average flow +/- 3 standard deviations The Toray pilot reported data on a more frequent interval than 5 minutes. The data set is filtered to report data at 5 minute intervals.

BASF Feed Turbidity Meter Calibration: For the BASF study, the feed turbidity meter was factory calibrated (refer to Appendix A for the calibration certificate) but not calibrated during testing. Pilot feed water (BAF filtered water) field sampling results were used to check the BASF pilot feed turbidity results. As shown in Figure 17, the pilot feed turbidity data generally agrees with the BAF filtered water quality; however, there are a number of elevated turbidity excursions in the BASF data. The elevated feed turbidity data may have resulted from the lack of field turbidity meter calibration or factors such as pilot system operations or biological growth in the pilot system upstream of the turbidity meter. Figure 17: Comparison of BASF Feed Turbidity Data to BAF Filtered Water Data Dow Fiber Breaks: The Dow module experienced two broken fibers at the start of testing that were repaired by November 5, 2014. After the fiber repairs, the DIT results indicated good fiber integrity during the remainder of the study. Dow Filtrate Turbidity Recording Interval: The filtrate turbidity recording interval for the Dow module was accidentally programmed to be 10 minutes rather than the 5 minutes required by the pilot study protocol. This issue was identified and corrected on February 6, 2015. A review of the daily DIT results, as well as the recorded filtrate turbidity data, indicate good fiber integrity during the pilot study once the two broken fibers were repaired on November 5, 2014. 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 11/4/2014 11/24/2014 12/14/2014 1/3/2015 1/23/2015 2/12/2015Turbidity (NTU)Date BASF Online Feed Turbidity BAF Filtered Water - Field Sampling Data points do not agree with EMWTP compliance monitoring data.

To account for this lost runtime, the pilot unit operated for approximately 32.7 days during Stage 5 testing to exceed the minimum 30 day requirement. Table 25 summarizes the total runtime for the Dow system. Over the course of the study, the pilot unit operated for approximately 110.7 days.

APAI contacted the TCEQ for guidance when the issue was discovered. It was determined that the lack of DIT data would not be an issue as long as sufficient data was collected in PACl Stages 5 and 6 (TCEQ Stages 2 and 3) of the study. DITs were performed daily to collect sufficient DIT results. A copy of the correspondence with the TCEQ is included in Appendix H. 6.6 PERFORMANCE CRITERIA REVIEW The BASF, Dow, Pentair, and Toray pilot study results were evaluated against the performance criteria (listed below). Table 26 summarizes the performance of each membrane relative to the criteria. 1. Filtrate turbidity less than 0.1 nephelometric turbidity units (NTU) 100 percent of the time2; 2. CIP frequency interval of no less than 30 days between CIPs; 3. Maximum 10 percent decrease in specific flux (corrected to 20°C) relative to baseline clean water flux conditions as measured following each CIP for the entire pilot test duration; 2 APAI reviewed the filtrate turbidity data provided in Figure 12 through Figure 15 to identify and investigate data points exceeding the 0.1 NTU criteria. The filtrate turbidity pe rformance criteria was deemed to be satisfied if noncompliant values could be correlated to backwash, CEB, CIP, DIT or alarm events or represented a single data point in order to account for the variable nature of pilot system operations.

Pass daily direct integrity tests (DITs) and DITs following CIPs that are performed in accordance with the Long Term 2 Enhanced Surface Water Treatment Rule and TCEQ requirements to achieve a minimum log removal value (LRV) of 4.0; 5. Fiber breakage for the pilot study of no more than 2 broken fibers per pilot system excluding any broken fibers that may occur during the two week startup and testing period; 6. CEB frequency interval of no less than 1 day between CEBs; and 7. Monthly average process recovery of no less than 95 percent (accounting for operat ions including forward flushes, backwashes, CEBs, CIPs, etc.).

Prior to the fiber repairs, the calculated LRV was less than 4.0. c BASF and Pentair completed Stage 5 and 6 testing using a CEB interval of 1 day. APAI has assumed a CEB interval of 0.5 days, because BASF and Pentair exceeded their recommended filtration TMP limit on multiple days during testing. Accordingly, BASF and Pentair did not satisfy the CEB performance criteria. d The reported recovery values are calculated using the Membrane Information Worksheet at the instantaneous filtrate flux (refer to Section 6.7 and Appendix E). The BASF and Pentair recovery values do not satisfy the performance criteria after modifying the CEB interval to 0.5 days.

The calculations are documented within the Membrane Information Worksheets included in Appendix E. The calculations were first performed using the temperature corrected flux to develop the requested net capacity for each vendor. The calculations were then repeated using the instantaneous flux (i.e. not temperature corrected) to provide a comparison with pilot study results. Table 27 summarizes worksheet results for calculations performed using the average temperature corrected flux, and Table 28 summarizes the worksheet results for calculations performed using the instantaneous flux. Based on the pilot study results, APAI requests that the TCEQ grant the following net capacities calculated using the temperature corrected flux3: A net capacity of 45,491 gpd at 20°C is requested for the 753-square feet (sf) BASF dizzer® XL 0.9 MB 70 WT module under the following operating conditions: o A total of 1,268 minutes per day in filtration mode and 172 minutes per day in other operating functions such backwash and maintenance wash; o An average filtrate flux of 71.6 gfd at 20°C; and o A gross filtrate production of 47,489 gpd and an in-plant use of filtrate of 1,997 gpd to yield a net filtrate of 45,491 gpd per 753-sf module at 20°C available for customer use.

The Membrane Information Worksheet calculations are in close agreement with the recovery reported by Dow and higher than the recovery reported by Toray. The assumptions used to perform the Membrane Information Worksheet calculations are provided in Appendix E. APAI assumed a CEB interval for BASF and Pentair 0.5 days, because both vendors exceeded their recommended filtration TMP limit on multiple days during testing. The CEB interval modification resulted in lower recoveries than the recoveries reported by BASF and Pentair for the pilot study. b The pilot study data does not necessarily substantiate the vendor recommended CIP frequencies.

BASF, Dow, Pentair, and Toray completed the pilot study protocol, and pilot study results for each vendor will be submitted to the TCEQ for review and approval. As a result of the study, the City gained exposure to the services and capabilities of four membrane vendors and three OEMs able to provide system integration services for the planned project. In the view of APAI, the pilot study results provide significant value to the City for their expansion efforts. The following conclusions are drawn from the pilot study results: The performance of each membrane vendor varied during the pilot study. APAI recommends that both pilot study results and full-scale operating history be considered when determining safety factors for developing full-scale design parameters (i.e. design flux, cleaning interval, etc.) and ancillary system design criteria (i.e. chemicals, feed pumps, storage tanks, etc.). The four membrane vendors completed the pilot study protocol using PACl and BAF pretreatment. Membrane performance varied between vendors. The BASF and Pentair membranes experienced multiple fouling events characterized by TMP values that approached or exceeded the vendor recommended filtration TMP limit. While the pilot study results indicate that the membranes recovered permeability after CIPs, a CEB interval of once per day was not sufficient to promote stable performance at the instantaneous flux rates selected by the vendors. Accordingly, APAI has assumed a CEB interval of two CEB events per day to complete net filtrate capacity calculations and to evaluate the BASF and Pentair membranes relative to the performance criteria. The intent of the increased CEB frequency is to acknowledge the need for additional chemical maintenance to manage fouling. The design CEB frequency may differ from the frequency used to complete the pilot study evaluation. APAI recommends considering the implications of filtration TMP, chemical maintenance frequency, pilot- study results, and full-scale installation history when selecting full-scale design criteria. The pilot study protocol included a required CIP as part of PACl pretreatment testing. Dow reported a permeability loss of 6.1-percent following the required CIP. APAI recommends considering the implications of Dow module permeability loss when selecting full-scale design criteria. Fouling issues were not observed with the Toray module during the pilot study. The Dow module experienced two fiber breaks at the start of formal testing. After the fiber repairs were completed on November 5, 2014, the Dow module passed subsequent DITs. Dow and Toray satisfied the performance criteria for the pilot study. BASF and Pentair satisfied five of the seven criteria. In the view of APAI, BASF and Pentair did not satisfy the CEB frequency and process recovery criteria. BASF, Dow, and Toray recommended CIP intervals of 60 days, 90 days, and 120 through 180 days, respectively. Pentair recommended that daily CEBs substitute for CIPs. The pilot study data does not necessarily substantiate the vendor recommended Eagle Mountain Water Treatment Plant Membrane Pilot Study Report (Draft) Alan Plummer Associates, Inc. 51 F:\projects\0318\054-01\Doc\Report\Draft\Draft Pilot Study Report_City Review\2015-07-21_Eagle Mountain WTP_Membrane Pilot Study Report (DRAFT).docx CIP frequencies. APAI recommends evaluating pilot study results and full-scale installation history prior to setting a design CIP frequency for the full-scale system. The four membrane vendors and three OEMs were responsive to requests during the pilot study and satisfactorily addressed equipment issues. Dow operated at the highest net filtrate capacity and Toray operated at the highest filtrate flux rate and recovery. 9 Acknowledgements APAI appreciates the opportunity to participate in the pilot study program.

The pilot unit was located on the Eagle Mountain Water Treatment Plant located at 6801 Bowman Roberts Rd, Fort Worth, TX 76179. The source water was from the Eagle Mountain lake and the pre-treatment process includes ozonation, coagulation/sedimentation, filtration with biologically active filters. 2 Objectives and Performance criteria The objectives of the pilot study were as follows: 1. Determine design flux, recovery, chemically enhanced backwash (CEB) frequency and regime, chemical clean-in-place (CIP) frequency and regime, chemical usage, electrical usage, as well as other design parameters for full-scale process design; 2. Identify multiple successful membrane Vendors as evaluated on the basis of demonstrated flux, recovery, backwash frequency, chemical cleaning frequency, and other considerations; 3. Evaluate BAF filtered water as a feed water source; 4. Evaluate ferric sulfate and PACl as coagulants and select a preferred coagulant for full -scale operations; 5. Satisfy TCEQ pilot testing requirements; 6. Determine design criteria for ancillary systems such as chemical feed and CIP systems; 7. Identify potential fouling issues and develop mitigation or cleaning solutions; 8. Familiarize staff with the operation and maintenance of the membrane proces s equipment and ancillary equipment. Ultrafiltration Pilot Study Page 7 of 91 The minimum performance criteria for the pilot test are provided below. Compliance with the listed performance criteria will be considered by the City when evaluating pilot study outcomes. 1. Filtrate turbidity less than 0.1 NTU 100% of the time; 2. CIP frequency interval of no less than 30 days; 3. Maximum 10 percent decrease in specific flux (corrected to 20°C) relative to baseline clean water flux conditions as measured following each CIP for the entire pilot test duration; 4. Pass daily membrane direct integrity tests (DITs) and DITs following CIPs that are performed in accordance with the Long Term 2 Enhanced Surface Water Treatment Rule and TCEQ requirements; 5. Fiber breakage for the pilot study of no more than 2 broken fibers per pilot system excluding any broken fibers that may occur during the two week startup and testing period; 6. CEB frequency interval of no less than 1/day; 7. Monthly average process recovery of no less than 95% (accounting for all operations including forward flushes, backwashes, CEBs, CIPs, etc.). Ultrafiltration Pilot Study Page 8 of 91 3 BASF Ultrafiltration (UF) Pilot Introduction 3.1 Multibore® Membrane The Multibore® membrane developed by inge GmbH is a hollow fiber membrane with an in-out filtration process. The feed water is sent to the 7 capillaries of each fiber and collected on the outside of the fibers. This arrangement represents a major innovation in the field of water treatment as it significantly increases the stability of the membrane. Approximately 2,200 membrane fibers are bundled together in plastic housings (called dizzer® modules), thereby ensuring optimum hydraulic properties, extremely high durability and a clean and safe treatment process. 3.2 Pilot Configuration The pilot unit contained two (2) UF modules; each of them part of a separate filtration trains. This allows for simultaneous testing of different parameters. Parameters such as coagulant type, dosage, contact time and pH can be tested simultaneously. Furthermore, the membrane operating parameters such as flux rate, TMP, backwash and cleaning frequency can also be varied separately. This pilot report shows the results from Line 1 only. Note: The membranes tested were installed after unpacking without any preconditioning step or procedure. Ultrafiltration Pilot Study Page 9 of 91 The following Table shows the list of instruments used for the pilot and their calibration processes. Table 1: Calibration Records 4 Pilot Schedule Table 1 presents the calendar for the different stages of the pilot study. The stage numbers refer to the initial APAI protocol which intended to have Stages 2 and 3 reserved for the test and validation with Ferric Sulfate. Following the analysis of the results Stage 1, Stages 2 and 3 were skipped and the pilot study moved directly to Stage 4.

Raw water pumping, addition of ammonia in the raw water to mitigate bromate formation 2. Travelling screens (about 2 " opening) 3. Ozonation with 3 to 4 ppm for disinfection, iron and manganese oxidation and taste and odor control 4. Lime addition at 16 mg/L (caustic is also added in small amount) 5. Vertical shaft rapid mixing and coagulation ferric sulfate, later switched to PACl for the pilot study; Polymer addition normally added in this step was discontinued for the pilot study. 6. Two-stage flocculation basins followed by sedimentation basins 7. Filtration using biologically active filters (BAFs) for turbidity removal, organic carbon reduction, biological stability, and additional taste and odor removal a. The inge pilot received water from the BAF as the feed water. 8. Chlorine and ammonia addition for chloramine formation and secondary disinfection. 9. Storage in clear well Figure 1: Eagle Mountain Water Treatment Process Ultrafiltration Pilot Study Page 11 of 91 5.2 Coagulant Dose The Eagle Mountain Water Treatment Plant doses coagulant to optimize turbidity removal out of the BAF, therefore, the plant aims to use as less coagulant as possible. The Ferric Sulfate dose varied between 25 and 40 mg/L during the pilot study. The Ferric Sulfate was replaced by PACl on December 4, 2014. The dose was initially 12 mg/L as product or 1.4 mg/L as AL3+ (up to 15 mg/L as product) but was reduced to 8 mg/L (as product or 1 mg/L as Al3+) during the testing period. Alan Plummer & Associates, Inc. recognized that PACl is not used for TOC removal as the TOC influent to UF has been approximately 5 mg/L, almost unchanged from raw data. Figure 2 shows the coagulant dosage. Figure 2: Coagulant Dosage Ultrafiltration Pilot Study Page 12 of 91 TOC REMOVAL TEST On February 26th, 2015 the efficiency of TOC removal was assessed by BASF/inge independently. To perform this test, the coagulant dose was adjusted to 0, 0.5, 1, 2, 3, 4 and 5 mg/L as Al3+ respectively. The coagulation was performed in-line with an estimated contact time of 15 sec before reaching the membrane. The coagulant used was the GEO UltraFloc® 2515 which is the current coagulant used by Eagle Mountain Water Plant. Following the dosage adjustment, a backwash was performed and 30 minutes of operation was measured before taking the samples. Samples for TOC were taken in an air - free bottle containing a preservative (phosphoric acid) and stored on ice. The samples were delivered to the laboratory the same day and analyzed with the SM 5310C method. The Figure below shows the result of this test. Figure 3 shows that a TOC removal of 5% was achieved with UF. A further removal of 25% of TOC was achieved by adding 3 or more mg/L of AL3+. Figure 3: TOC removal vs Al3+ dosage Ultrafiltration Pilot Study Page 13 of 91 5.3 Grab Samples The Hardness and Alkalinity were taken daily and the values varied as follow: Hardness: 84 to 103 mg/L as CaCO3 Alkalinity: 92 to 120 mg/L as CaCO3 The complete results for these two parameters are available in the Appendix A. The Eagle Mountain Water Treatment Plant also conducted a sampling campaign for different parameters and the results are shown below in Table 3.

Those low turbidity can be explained by the fact that the feed water for this pilot was coagulated, settled and filtered through sand/anthracite media. Ultrafiltration Pilot Study Page 17 of 91 The UF filtrate turbidity was 0.011 NTU for 99% of the time and the spikes over 0.05 NTU are believed to be due to measurement errors such as air bubbles in the turbidimeter. Filtrate turbidity was below 0.1 NTU 100% of the time and the membrane complied with the first performance criteria. Ultrafiltration Pilot Study Page 18 of 91 Figure 4: Daily Average Feed and Permeate Turbidity Ultrafiltration Pilot Study Page 19 of 91 5.5 pH and Temperature The Eagle mountain water treatment plant adjust s the pH to 7.9 with a lime. The pH was stable for the entire study. Figure 5 shows that the temperature gradually declined as the study advanced into the winter months. The lowest temperatures were recorded during the last week of February and were about 4 C (39 F). Ultrafiltration Pilot Study Page 20 of 91 Figure 5: Daily Average pH and Temperature Variations Ultrafiltration Pilot Study Page 21 of 91 5.6 Membrane Integrity Tests The membrane Integrity Test (MT) or pressure decay test was performed every day. The test followed the following protocol: 1- Dewatering – 30 sec to 5 min During the de-watering, the compressor injects air at a pressure or 1.25 bars (18 psi) to the feed side of the module. Through the membrane pores, water is pushed out of the capillaries by the pressure but because of the surface tension of the remaining water in the pores, the air is contained in the feed side of the module. The details on the pressure needed to achieve a 3 um resolution are available in the appendix. 2- Stabilization – 30 sec to 2 min During the stabilization period, the air valve is closed which allows equilibrium to be made. During that period, the following phenomenon will take place but will not impact (due to their nature) the outcome of the test. First, the fibers will adjust (expand) to new pressurized environment. The diffusion of pressurized air to the water will be more rapid as the difference in air concentration between the interface air-water is at its maximum at the beginning of the test. Finally, for a larger system where a leak can be present in the piping, a baseline will be identified. 3- Pressure decay test – 1 to 5 min During the test, the pressure is recorded at the beginning and at the end of the testing period. The difference between the feed and permeate side of the membrane are monitored so the difference does not go below the threshold. 4- Air removal In this pilot study, a backwash was used to remove the air in the feed side of the membrane after the test. This can also be achieved by a forward flush. Figure 6 shows a variation of the test value from day to day. A variation in the pressure decay test is unusual and since no bubbles were detected, an investigation on the cause of this variation was undertaken. Ultrafiltration Pilot Study Page 22 of 91 It was found that the cause of the variation was an insufficient dewatering time. Prior to February 10, 2015 After February 10, 2015 De-watering: 60 sec De-watering: 120 sec Stabilization: 60 sec Stabilization: 60 sec Pressure Decay Test: 300 sec (5 min) Pressure Decay Test: 300 sec (5 min) Throughout the entire study, the pressure decay rate was consistently under 0.27 psi/min which is the upper control limit for a Log Removal Value (LRV) of 4. The detail ed calculation of the upper control limit is available in the Appendix D and the complete set of result is in the Appendix G.

Figure 17 shows that the permeability decrease, with daily CEBs, was from 25 gfd/psi after the CEB to 5 gfd/psi before the CEB. On the same Figure, it can be seen that the Membrane Integrity Test (MIT) as well as the Caustic/Acid CEB help in recovering the permeability. It could be observed that the normal backwash could not recover the permeability completely and the relativ e permeability drop between CEB/MIT cycles were fluctuating between 25-10 or 25-5 gfd/psi. This suggested that the UF feed water quality was fluctuating and contained a certain amount of dissolved organic/inorganic compounds. The assumption was confirmed by a manual measurement of Al, Fe, where an increased iron value of 0.3 ppm Fe could be found in the MIT backwash water (Table 2). Nonetheless, a lab result provided on January 13th, 2015 showed a DOC value of 4.6 ppm (Sample date 22 Dec, Table 2). On January 20th, a connection on the strainer broke sending water on the pilot floor and ancillary equipment. The pilot was shut down by the operators of the Eagle Mountain WTP. One of the operators was able to repair the connection and the plant was put back online after approximately 12 hours of stopped time. On January 23td, 2015, the pH probe on the discharge line suddenly stopped providing a signal. Fortunately, on the same day, it was manually confirmed that the target cleaning pH (12 and 2) was reached during CEBs. The probe was repaired on January 29th.

Since air can oxidize certain soluble particles like Fe and Mn, it is possible that these particles can be subsequently flushed from the membrane when the membrane was flushed and deaerated after the MIT.

It was found that the acid pump was not operating from January 27 th, 2015 to January 31st, 2015. The reason was found to be simply an omission to turn on the acid dosing pump after to the acid tank was refilled. It was not noticed immediately because the pH probe, offline since January 23rd, had not been repaired prior to January 30th, 2015. The permeability started to recover as soon as the acid dosing pump was reactivated and the acid CEBs reintroduced. On January 29th, 2015, a series of Membrane Integrity Tests (MIT) were performed in an attempt to identify a possible air leak in the piping surrounding the module. Although no bubble was identified in the permeate, the Pressure Decay Rate (PDR) was higher than usual and a leak in one of the unions (piping) or valve was suspected. As explained in Section 5.6, it was found that the dewatering duration was insufficient which resulted in a higher PDR value. There was no integrity problem with the fibers.

Details of the CIP process and pH settings are detailed in Appendix C. It is noted here that the CIP were performed at ambient temperature. The main objective of this CIP was to establish whether or not the membrane was irreversibly fouled. Figure 32 shows that the permeability on Line 1, directly after the CIP was 30 gfd/psi. This compares well with Figure 29 where the permeability at the beginning of the verification test was 27 gfd/psi. Post CIP result confirms that there was no irreversible fouling.

From February 11th to February 26th, 2015, the last stage of the pilot study was completed. For Stage 6 of testing, the % loss of the original specific flux was established and the irreversible fouling was assessed. Stage 6 involved operating the membrane modules at the simulated full -scale operating conditions from Stage 5 for at least 14 days.

The filtrate turbidity was less than 0.1 NTU 100 percent of the time; 2. The CIP frequency interval was 30 days for this pilot only to comply with the stage structure of the pilot study. 3. There was no decrease in specific flux (corrected to 20°C) relative to baseline clean water flux conditions as measured following each CIP. 4. All the daily direct integrity tests passed successfully. There was no fiber breakage during the entire study. 5. CEB frequency interval was set to once per day for the validation period. Monthly average process recovery was set to 94.8% to account for varying feed water quality. Ultrafiltration Pilot Study Page 69 of 91 10.2 Findings: 1. Coagulation with PACl was observed to less fouling to membrane than coagulation with Ferric Sulfate 2. With PACl, a stable operation with 50 gfd with daily caustic/acid CEB is possible, even at low water temperatures and fluctuating feed water quality values. The recovery at those parameters is 94.8%. The caustic CEB (pH 12.3) and acid CEB (pH 2) showed excellent cleaning results based on following recipes: Guideline CIP #1 CIP #2 CIP #3 Step 1 First cleaning agent Base NaOH NaOH+NaOCl NaOH pH 12 to 13 12.5 12.4 12.5 Recirculation Flow rate 6 to 15 GPM 15 gpm 15 gpm 15 gpm Duration 60 min to 12 hours 4h 12h 4h Temperature (F) 55 45 50 Step 2 Second cleaning agent Mineral Acid H2SO4 H2SO4 H2SO4 pH 1 to 2 1.7 1.6 1.5 Recirculation Flow rate 6 to 15 GPM 15 gpm 15 gpm 15 gpm duration 60 min to 12 hours 2h 2h 2.5h Temperature (F) 55 45 50 Total duration 6h 14h 6.5h 3. NaOCl clean is not needed and a separate and extra caustic or acid cleans didn’t show better effects. 4. A 5% TOC removal is achieved with UF. 5. No irreversible fouling was observed since the recovered permeability after each CIP is greater or equal to 27 gfd/psi. The membrane maintained an average permeability of 17 gfd/psi independent of the operating parameters. 6. During this pilot, a 30-day CIP interval was conducted. However, the TMP trend for 15-min data of the Verification Stage (Figure 18) indicated that a TMP was not necessary after 30 days of operation. We recommend a CIP interval of 60 days as a start and adjust to longer intervals depending if the TMP trend consistently remains below 7-8 psi.

Ultrafiltration Pilot Study Page 74 of 91 Appendix C – Summary of inge® Filtration Processes Production (Filtration) In filtration mode, source water is treated by being forced through the ultrafiltration membrane from the feed side to the filtrate side. Contaminants in the water, which are blocked by the filtration surface, accumulate on the inner surface of the membrane capillaries. The filtrate flows into the filtrate/backwash tank, which serves as a storage container for the backwash water. The amount of water that can be treated by a module depends on a number of factors, including the origin of the water being treated (e.g. groundwater, surface water, seawater, or pretreated wastewater), the composition of the source-water (e.g. turbidity, concentration of solids, dissolved organics/inorganics, temperature), and the chosen cost strategy (capital cost, operating costs). The diagrams below show the two operating modes "Filtration Top" and "Filtration Bottom" in dead-end mode. The first Figure shows filtration being performed from top-to-bottom (FT) with the source-water being fed into the top of the module, while the second shows filtration being performed from the bottom to top (FB) with the source-water being fed into the bottom of the module. Filtration Top Ultrafiltration Pilot Study Page 75 of 91 Filtration Bottom The following diagrams show the two backwash operating modes "Backwash Top" and "Backwash Bottom". The first diagram shows a Backwash Top (BWT) in which the b ackwash water (filtrate) flows through the module from top-to-bottom, while the second shows a Backwash Bottom (BWB) in which the backwash water (filtrate) flows through the module from bottom-to-top. Backwash Top Ultrafiltration Pilot Study Page 76 of 91 Backwash Bottom Ultrafiltration Pilot Study Page 77 of 91 Chemicals for CEB and CIP The table below shows the list of the chemicals used for the CIP and CEB processes. Apart for the Sodium Bisulfite, all the chemicals were used for both the CEBs and CIPs. Table 6: Cleaning Chemicals Type Name and formula Bulk Concentration Cleaning Solution Concentration Comment Base: Caustic (NaOH) 50% Target pH: 12.3 Acid: Muriatic Acid (HCL) 20% Target pH: 2.0 No difference in efficiency were detected during the cleaning Sulfuric Acid 25% Target pH: 2.0 Oxidant: Chlorine Solution (NaOCl) 12% 500 ppm Used during CIP only. Concentration is approximate Reducer: Sodium Bisulfite (Na(SO4)2) 100% (powder) 2% Concentration is approximate Only 1 CEB was performed with (Na(SO4)2). CEB (Chemical Enhanced Backwash) A chemically enhanced backwash (CEB) is used to boost the effectiveness of a backwash. It is performed after a defined number of operating cycles, either after a backwash or after a forward flush. The standard cleaning process carried out before the CEB removes large particles from the membrane. This enhances the effectiveness of the cleaning solution in the subsequent CEB. Ultrafiltration Pilot Study Page 78 of 91 The CEB is essentially performed in a similar way to a backwash, i.e. filtrate flows from the filtrate side to the feed side. In addition, a cleaning chemical is added to the filtrate to boost the effectiveness of the process. The Figure below shows the basic sequence of steps generally used to perform a CEB based on typical values for the respective parameter settings. To introduce the chemicals into the system, a flux rate is established (referred to here as the intake flux) of approx. 120 LMH (71 GFD), which is lower than the backwash flux rate. Once the rack has been completely filled with cleaning solution (controlled b y the chemical injection time setting), chemical dispersion ceases and the system enters standby mode. The time required to wash the chemicals into the system in a CEB depends on the position of the dosing points and on the respective flow velocities in the backwash piping and in the piping systems built into the rack. At an intake flux rate of 120 LMH (71 GFD), the chemical intake time measured from the moment the CEB solution enters the T-Rack until the entire time period is referred to here as tint. This marks the beginning of the soak period. Once the soaking time has elapsed, the chemical solution and the substances removed from the membrane must be washed out of the rack with filtrate. This is achieved by means of a Backwash Bottom (with a duration of approximately 30 seconds) followed by a Backwash Top (also with a duration of approximately 30 seconds). Flux rate for rinsing out the solution should be at least 230 LMH (135 GFD) just like a normal backwash. Ultrafiltration Pilot Study Page 79 of 91 The total chemical intake time total is t he sum of tint and the time period which is defined as the time required for the CEB solution to make its way from the dosing point to the rack. The precise Figures for these two time periods are calculated as part of the system commissioning process. The normal CEB process is conducted in 2 steps; during the first step, the caustic (with optional oxidant) is added to the solution. This step principally targets the organic material. The second step of the CEB process is the acid clean (with optional Red ucer). This step principally targets the inorganic contaminants. CIP (Clean in Place) Clean-in-place (CIP) is an effective method of restoring membrane performance by tackling the kind of fouling and scaling that is difficult to remove using conventional backwashes or chemically enhanced backwashes (CEBs). This type of fouling may occur due to difficult operating conditions, for example in situations where there is significant fluctuation in the quality of the feed water, or as a result of improper use, such as a lack of effective pre-treatment, excessive flux rates or incorrect doses of chemicals. As a rule, CIP is not required in normal operation. A CIP is performed by introducing a chemical solution into the modules and shutting down the membrane system for a longer period of time than is required for conventional cleaning methods. One of the major differences to a CEB is that a CIP is characterized by a forward flush with the circulation of different chemicals using a CIP tank on the feed side and an extended soak time (in some cases the feed tank can also be used as a CIP tank). Step by Step Description 1. The CIP starts by filling the CIP tank (in the case of this pilot study, the feed tank is also used as a CIP tank) with permeate water. 2. The cleaning chemicals are then injected in the CIP tank. Similarly to the CEB process, the CIP process is conducted in 2 steps; during the first step, the caustic (with optional oxidant) is added to the solution. This step principally targets the organic material. The second step of the CEB Ultrafiltration Pilot Study Page 80 of 91 process is the acid clean (with optional Reducer). This step principally targets the inorganic contaminants. 3. For the first stage of the first step, recirculation takes place via the feed side for at least 60 minutes in order to perform initial cleaning of the fiber lumen. The filtrate valve is closed during this procedure. The CIP pump (feed pump was used as the CIP pump for this pilot) is used to recirculate the cleaning solution. The recirculation flow rate is set to 6 to 15 GPM per module. It is important to ensure a feed side venting. Although the cleaning solution temperature will slightly rise because of the recirculation (waste heat from the pump), the cleaning solution was not heated for this pilot. If the chemical solution is to be heated, it should be slowly heated to 30-35°C while it is circulating through the system. Do not exceed the maximum permitted rate of temperature change or the maximum permitted operating temperature for the modules. 4. Once at least 60 min have passed (but no more than 12 hours) with the solution circulating exclusively through the feed side, the process moves on to a second stage in which the filtrate side is incorporated in the recirculation process. This involves opening the filtration valve and throttling the feed top valve to allow a partial flow (50%) of the cleaning solution through the membranes into the filtrate return. It is important to ensure a filtrat e side venting. Ultrafiltration Pilot Study Page 81 of 91 During the entire circulation process, which should last for at least a further 60 min (but no more than 12 hours), it is important to ensure that the chemical solution circulates through both the feed and filtrate sides. 5. The last stage of this step is to rinse the chemical out of the membrane. The feed side is first emptied and rinse with the feed pump. Then, the filtrate side is rinsed with the use of a Backwash. 6. Once the first step is completed, the second steps starts by repeating p oints 1 to 5 with the acid and optional reducer agent.

This module is a pressurized vessel with hollow fiber PVDF membranes operated in dead‐end mode. Specific membrane details are summarized in Table 1 with additional product literature provided in Attachment 1.

A copy of the NSF microbial challenge test report for the study conducted to obtain the ETV log removal credits is included in Attachment 2. TCEQ Challenge Test The Dow IntegraFlo DW102‐1100 UF Module is approved by TCEQ for a LRVc‐test of 6.3 removal of Cryptosporidium for systems operated in deposition mode. A copy of the TCEQ approval letter is included in Attachment 2. 3.3 Integrity Test Procedure and Calculations LRV Testing ‐ Background and Explanations LRV testing is conducted on Ultra Filtration equipment in order to prove the integrity of the membranes and provide a credit for the removal of pathogens for a water stream. The final objective of the LRV calculations is to prove the Ultra filtration system is providing a 4‐log removal of Cryptosporidium, without having to actually count the bacteria on the inlet and outlet water piping. 4‐Log removal indicates at least 99.99% of the contaminant is removed. The testing on the UF system and the LRV calculations required to prove a 4‐log removal of cryptosporidium are provided in the USEPA ‐ membrane filtration guidance manual. This manual stipulates that testing should be performed on a regular basis. Wigen systems will perform baseline testing and calculate the LRV removal credit for Cryptosporidium on a daily basis. There are several ways to calculate a breach in the membranes on a UF system. One uses a laminar flow model, called the Hagen‐Poiseuille model. This calculation however always gives a higher result for the log removal value than the calculation that takes into account turbulent flow through a breach. This calculation is based on the Darcy pipe flow model, and will be used in the LRV calculations on Wigen UF Equipment, thereby providing a more conservative value for the log removal credit. Each skid unit will perform a separate LRV test at the start of the running sequence every day. The start‐up sequence includes an initial run of the UF filters. This run time is set as the time between backwashes. The initial run is needed in order to obtain that day’s operating parameters in the calculations. After the first Backwash / Drain cycle is completed, the feed side of the membranes will be pressurized with air to above the Minimum Test Pressure calculated. Once the pressure is set, all the valves on the feed side of the membranes will closed, with the filtrate valves opened, in order to analyze the pressure drop over time. The test time depends on the number of modules in the skid unit. The drop over time decreases as the number of modules increases. This means that the more modules there are on a skid unit, the longer the testing times needed to see the same pressure drop due to a single breach in the membranes. To prove that there is no breach, a lower pressure drop over the same amount of time is needed. There will always 7 be a slow diffusion of air through the membranes, which is taken into consideration in the LRV calculations. The next sections of this tutorial will break down the calculations that are performed during LRV calculations, and explain where the variables and observational numbers are coming from. Calculating ‐ Minimum Test Pressures In order to perform a LRV calculation on a working UF system, you must first calculate the minimum test pressure. This calculation takes into account the membranes resistance to allowing air to pass the surface, in comparison to the size of a breach. It is finding the minimum differential pressure at which air will pass through a 3um breach in the membrane surface. The following equation will be used for this calculation: Ptest min = (0.58 * K * σ * cos θ/d) + BPmax Where: Ptest min = Minimum gauge pressure that the LRV test must start at (PSI). 0.58 = Constant which includes the defect diameter (3um test resolution) and unit conversions. K = 1, the most conservative value. σ = 75.4 Dynes/cm, the surface tension of water at 5 degrees C. θ = 0, the most conservative value. d = 3 microns, the detection resolution. BP = The back pressure that the filtrate side of the membranes will experience, converted from inches of water with a measurement from the high point of the filtrate piping, to the bottom of the membrane modules. With no filtrate piping above the skid on the pilot (BP = 15” water or 0.55 PSI average) provides a Ptest min = 15.10 PSI. This is the minimum pressure of the test air in a LRV test to see a 3 micron breach. Calculating ‐ Darcy Pipe Flow ALCR Values The Air Liquid Conversion Ratio (ALCR), is a dimensionless value that deals with the difference between air and water penetrating a breach in the membranes. In order to create the most conservative estimate for the LRV value, we will use values in this equation that will provide the highest ALCR, but still be within the design of the UF system. The ALCR equation is from the EPA filtration manual (equation C.4), and is provided below: Where: TMPT PPBPPYALCRatmtesttest DP 460170 8 ALCRDP = Air Liquid Conversion Ratio, a dimensionless constant that is used to calculate the LRV value. 170 = Constant incorporating unit conversions to use US units. Y = Derived from equation C.5 (See Below) Ptest = Initial gauge air pressure applied to the membranes during the test (PSI). BP = Backpressure on the filtrate side of the membranes (PSI). Patm = Atmospheric air pressure at the site, dependent on elevation of site (PSI). T = Temperature of the water feed (in degrees F). TMP = Transmembrane pressure on the Toray modules during operation (PSI). Y is a relationship involving the pressure of the test, and the type of membrane used. To determine the value for Y, it is necessary to use the relationship given in the EPA Filtration manual as Equation C.5, provided below: Where: Y = A dimensionless relationship between the membrane used, and the pressure of the test, derived from a straight line equation taken from page A23 ‐ Crain, Flow of Fluids. K = A dimensionless constant for all Dow Modules, defined below: K = F * (L/Dfiber) Where: K = A dimensionless relationship between the type of membrane used, length of membranes, and the diameter of the fibers. F = 0.026 for all Dow PVDF Membranes, Friction Factor (from iterative method). L = 56, Length of fiber in the potted material (in mm). Dfiber = 0.7, Diameter of fibers (in mm). Using these values for the derivation provides a K value of 2.08. This is the K value to be used on all Dow membrane modules. For this K value, an analysis of the Graph on page A23 ‐ Crain, Flow of Fluids, provides the equation below for the value of Y: Y = ‐0.543 * ((Ptest ‐ BP) / (Ptest +Patm)) + 1 K PP BPPY atmtest test ,1 9 This value can then be input into the ALCR equation to determine the value for the ALCR for that test, or to determinate the sensitivity of the LRV test. Each actual test will have a different ALCR value calculated and applied; as the test pressure, back pressure, temperature and transmembrane pressure will change over time. Calculating ‐ LRV Sensitivity Value In order to be sure the LRV calculation will be sensitive enough to determine a value above 4, a sensitivity calculation must be made on the system parameters. These parameters will be set at the most conservative values for the system, using the lowest measurable pressure drop over the span of the test. This provides a maximum sensitivity, in the worst case scenario. The LRV calculation, provided in the EPA Filtration Manual as equation 4.9, is used to determine the log removal value for the system. Where: LRVDIT = Log removal value (LRV) for this system with the design parameters set at the most conservative, and the test pressure drop at the most sensitive. Qp = Design flow rate of the UF system (46 GPM). ALCR = Derived from equation C.4, using the highest anticipated water temp (70 deg. F), backpressure on filtrate (0.55 PSI), and transmembrane pressure (30 PSI) for the Dow UF system (See above equation derivation) Patm = Atmospheric air pressure at the site, dependent on elevation of site (14.3 PSI for an elevation of 653 ft). ∆Ptest = Test pressure drop = Initial gauge air pressure, minus Final gauge air pressure, divided by the time of test (∆PSI/min). For the sensitivity calculation, this value is 0.03 PSI/min. The UF system volume is 10 gallons) and the VCF = Volume correction factor = 1 In order to determine the absolute sensitivity of the LRV test, it is necessary to input the most conservative values for the variables on the UF system that is being calculated. This includes the most conservative values for calculating the ALCR, which are the highest anticipated water temperature, the highest permissible transmembrane pressure, and the highest possible backpressure on the filtrate side of the membranes. These conservative variables are coupled with the lowest measurable pressure drop that can be determined during the test. The LRV result provided with these inputs is the highest possible LRV for this UF system. Using the values in bold above, the LRVsensitivity = 4.89 log removal of Cryptosporidium. Calculating ‐ LRV Current Valve VCFVP PALCRQLRV systest atmp DIT log 10 To calculate the actual test LRV value it is necessary to input the actual test data into the variables provided for in the LRV equation: Where: LRVDIT = Log removal value (LRV) for this system with the actual test results input. Qp = Actual average flow rate of the UF system in the last operations cycle (in GPM) ALCR = Derived from equation C.4, using the actual test water temp (in deg. F), backpressure on filtrate (in PSI), and average transmembrane pressure (in PSI) for the UF system in the last operations cycle (See above equation derivation) Patm = Atmospheric air pressure at the site, dependent on elevation of site (14.3 PSI for an elevation of 653 ft). ∆Ptest = Initial test air pressure, minus final test air pressure, divided by the time of the test (∆PSI/min). This pressure drop rate is then reduced by the diffusion rate established with no leaks in the system, which is a baseline number determined at startup. Vsys = Total volume of air in the pressurized system (10 gallons) VCF = Volume correction factor = 1 If this calculation with the actual test parameters input, results in a LRV below 4, the test has failed. If the value is above 4, the test has passed.

The water was then pumped via a feed pump mounted on the UF pilot skid through an Amiad automatically cleaned 200 Micron screen filter to the membrane modules at a maximum pressure of 39 psi. The feed water was fed into the UF module on the outside of the membrane fiber, retaining any particulate matter, while the filtrate water permeates through to the inside of the hollow fibers and exits the top port of the membrane module. The filtration cycle continues for approximately 45 minutes, during which time the trans‐membrane pressure (TMP) increases due to accumulation of particulate on the membrane surface. After operating in filtration mode for 45 minutes, the suspended solids are removed from the module using the backwash cycle described below. In the backwash cycle, feed to the module is shut off. Air is then injected at a rate of 9 to 7.5 CFM using compressed air from the air compressor system into the bottom of the module to scour the membrane fibers with bubbles for 30 seconds. After Air scour, the module is drained by the drain down pump, flushing out any particulate matter that was dislodged during the air scour operation. This drain / flush process removes the majority of the particulate that accumulated in the module during the filtering operation. After the drain down, filtrate stored in the backwash tank is pumped into the feed side (inside) of the hollow fibers for 30 seconds out of the top of the module, and then another 20 second out of the bottom / feed port of the module. After the backwash step, the system will refill with feed water, by starting back up the Feed Pump and filling the module until water starts exiting the top backwash outlet port on the module. This should take about 20 seconds. The overall backwash cycle requires approximately 180 seconds. After the Backwash, the pilot will return to making filtrate, counting down for the next backwash cycle, 45 minutes later. All backwash steps timing and flow rate set‐points can be changed as operating experience is gained, to optimize the systems operations. These settings are detailed in the individual stages of the pilot report for this test. Additionally, periodic Chemically Enhanced Backwash (CEB) cleans will be performed on the membranes at regular intervals. CEBs are initiated by time of filtering operation and will be performed using a either Acid solution or Chlorine solution at different intervals to maintain the permeability of the membranes. The process for these CEBs uses the same Backwash Pump and chemical injection pumps to inject the needed chemical into the backwash flow as it enters the module. The chemical is then allowed to soak for set amount of time, before being flushed to drain. Overall these CEB cleans will keep the permeability of the membrane at a steady state of operation. The typical time that a UF Skid is off line during a CEB Cleaning is 20 to 30 Minutes. CIP Cleaning were also be performed at the end of the test stages, or when the Trans‐membrane Pressure (TMP) approaches a set maximum, and the backwash and CEB cleanings are not causing the TMP to drop sufficiently. CIP cleaning utilize a CIP tank, pump and heaters, to circulate a highly concentrated, heated cleaning solution across and through the membrane. The system is manually initiated by the operator, but then progresses automatically to the setpoints input into the system. The typical time for a CIP cleaning is 2‐4 hours per chemical used, depending on the amount of fouling encountered. CIP Cleanings can be performed with either an Acid solution or a mixed Sodium Hydroxide solution and Sodium Hypochlorite solution. CIP parameters are detailed in the CIP reporting section of this report. 13 Membrane Integrity Tests (MIT’s) are performed on a daily basis by pressurizing the feed piping and module on the UF Skid with compressed air to a pressure of around 20 psi. Once the water has been purged from the system the pressure on the feed side of the module is monitored and recorded to evaluate the pressure drop, and therefore membrane integrity. At the end of the test the air is purged and the system returns to normal operation. The test lasts approximately 5 minutes, and can also be manually initiated on the HMI control screen. Calculations are performed on the operating characteristics of the system, in conjunction with the recorded pressure drop of the test to determine the theoretical overall log removal of Cryptosporidium from the feed water. 14 4.0 ANALYICAL METHODS Calibration procedures were performed on the following analytical systems during the visit to the site on 11/3/2014 to 11/5/2014.

Calibration certificates for the Flow meters and Turbidity meters on the system are provided in Attachment 7. 15 5.0 RESULTS AND DISCUSSION 5.1 Pilot Study Operational Parameters During the pilot testing, operational parameter settings were applied for different Configurations during Stage 1 of the pilot study. The objective was to achieve a reliable system while maximizing water production, minimizing chemical use, waste generation, and energy consumption. Membrane fouling was monitored and modifications were performed to optimize the operation accordingly. The start‐up of the pilot was on October 28th followed by a few days of commissioning work. Operational parameters and water quality data were analyzed for each stage of the pilot study. The stages were: Stage 1 ‐ Optimization phase with Ferric Sulphate Stage 4 ‐ Optimization phase with PACl Stage 5 ‐ Minimum of 30 days with continuous operation Stage 6 ‐ Verification Run after CIP Stages 2 and 3 were not completed after it was determined during Stage 1 that the ferric sulfate did not yield the expected performances for all the pilots. Tables 3 and 4 below summarize the system’s operational parameters during the different phases of the Pilot Study.

During this stage of testing, the goal was to optimize the treatment process in terms of flux, filtration time, chemical cleanings and overall system recovery, while obtaining a sustainable operation. This stage was operated with filtrate fluxes ranging from 60 to 45 gfd (Figure 3) and filtration time from 60 to 45 min. The unit began operation with a flux of 60 gfd, filtration cycle of 60minutes, and CEBs consisting of 250ppm NaOCl every 8 days and 550 ppm HCl every 14 days. The recovery of the system at these conditions was 97.9%. Following a rapid TMP increase with this initial configuration a few changes to the operational parameters were performed. Increasing the flux of the Backwash (BW) and setting more frequent chemicals cleanings contributed to finding the optimal combination of parameters for a sustainable process performance. At the end of this stage, the flux was set at 45 gfd and the filtration cycle at 45 minutes. The cleaning regimen was also set at different frequencies targeting the potential fouling episodes. The optimized CEB cleaning regimen was defined as 500ppm NaOCl every 4 days and 550 ppm HCl every 15 days. With 16 days of operational data at this configuration (from November, 18th, 2015 to December 4st, 2015) it was determined that sustainable operation was achieved. The average temperature corrected flux (at 20°C) during this last configuration was 56 gfd. 17 The Specific Flux at the beginning of this stage was 3.7 gfd/psi, and the Specific Flux at the conclusion of Stage 1 was also 3.7 gfd/psi. That shows no loss on Specific Flux over Stage 1. After 29 days of runtime on stage 1, the decision was made to perform a CIP even though the performance of the unit did not signal a need to clean. The CIP was performed in order to start the next stage with a clean membrane. The idea was to eliminate all of the possible fouling due to the Ferric Sulphate used until this point and have a continuous pilot trial without this variable, however small influence it could cause. Upon restarting the unit post CIP, the Specific Flux was 4.9 gfd/psi. When compared to the Specific Flux immediately before the CIP the unit exhibited a 132% recovery of Specific Flux. Therefore, it can be determined that the unit was able to recover to acceptable levels due to complete cleaning of reversible fouling of the membrane. For the next stages the value of 4.9 gfd/psi is going to be used as the reference to calculate % Recovery of Specific Flux as well as % Loss of Specific Flux. During Stage 1 the system went through a few downtime moments. On November 5th, 2014 the pilot experienced a 4.3 hours of down time due to a fiber pinning procedure. On November 13th, 2014 the pilot experienced 9.5 hours of downtime due to WTP issues. This downtime was not related to the UF pilot operation. The third and last downtime on stage 1 was on November 22th, 2014. After the system was re‐ started in those 3 moments, the system returned to normal operation.

The initial PACl dose was 15 mg/L and it was further optimized to dosages between 5 and 10 mg/L. Stage 4 started on December 15th, 2014 and no adjustments were made to the operational parameters from the previous Stage. The rate of increase in normalized TMP during filtration, after a BW and after a CIP, was higher compared to Stage 1 where Ferric Sulfate was being used. That could indicate a higher degree of fouling development on the surface of the fibers, but BW and CEB were still getting the TMP back to a similar level as Stage 1.

This stage started with specific flux of 4.9 gfd/psi and at the end of 32.7 days had 3.6 gfd/psi. The % Loss of Specific Flux on this stage corresponds to 26.5%. After the CIP was performed 93.9% of the specific flux was recovered considering the reference value of 4.9gfd/psi established at the first CIP performed. On January 27th, 2015 the pilot experienced approximately 31 hours of down time, from 1:19 PM to 8:32 PM on January 28th due to the feed pump malfunctioning. After the system was re‐started, the system immediately returned to normal operation.

The filtrate water quality produced by the Dow module met the water quality goals. Stage 1 had the highest feed water turbidity values for the entire pilot trial, giving also the maximum value for Turbidity log removal of 2.198. The average filtrate turbidity for this stage was 0.014NTU. On this stage we also see the maximum filtrate turbidity value that was consequence of one broken fiber. During that episode the filtrate turbidity reached the highest value of 0.49NTU and after the fiber pinning went back to <0.1 NTU. Stages 4, 5 and 6 all have filtrate turbidity values of less than 0.037NTU.

The turbidity logging was changed from every 10 minutes to every 2 minutes on 2/6/15 at 9:30 in the morning. 5.7 Integrity Test Results A table of all of the integrity test results during the pilot study is shown in Attachment 6. There were some integrity test failures during commissioning of the pilot plant between 10/28 and 11/4 due to two fiber breaks and a leaking valve. After these fibers were pinned and the valve repaired, the membrane passed all integrity tests from 11/5/14 until the completion of the pilot study on 2/25/15. Between 11/5/14 and 2/25/15, the average pressure drop during the pressure decay test was 0.51 psi over 5 minutes and the average LRV result was 4.29 log removal. The Maximum LRV result from a pressure decay test resulted from a 0.3075 psi pressure drop over 5 minutes with a LRV result of 4.44 log removal, on Feb. 20th 2015. The Minimum LRV result from a pressure decay test resulted from a 0.8589 psi pressure drop over 5 minutes with a LRV result of 4.008 log removal, on Dec. 6th 2014. 5.8 Membrane pre‐conditioning method Prior to the beginning of the operations the module was rinsed to remove any preservative fluid shipped in the modules. Flushing was performed for 2 hours. During the flushing period 20% of the flow rate was being rejected from the concentrate side on a cross‐flow mode and the balance of 80% was being filtrate . The procedure was done at 47gfd. After the rinse procedure a CEB using 250ppm of Sodium Hypochlorite and a second CEB with 550ppm of Hydrochloric Acid was also perform. 31 6.0 CHEMICAL CLEANING SYSTEM The UF pilot system employed CEBs and CIPs as part of the overall operation. The CEBs were programmed to occur automatically following a specific frequency, depending on the stage on the operation. Two types of CEBs were utilized during the study. For CEB1 NaOCl was used (dosage varied from 250 to 500ppm), and for CEB2 HCl (550 ppm) was used. Details of the different parameters used on the CEBs are shown below in Table 13 for Stage 1.

Duration of 150 seconds. Notes: Circulated solution was at a pH of 1.6 during the 3 CIP cleanings and no large increase in pH was observed in any of them. Acid CIPs were performed on December 11th, 2014 for Stage1, on January 7th, 2015 for Stage 4 and on February 11th, 2015 for Stage 5. Alkali CIPs were performed on December 12th, 2014 for Stage1, on January 8th, 2015 for Stage 4 and on February 11th, 2015 for Stage 5. Based on TMP trends over the pilot trial one can expect that a CIP procedure wouldn’t be required more frequently than every 3 months of operation. This frequency was estimated considering an initial NTMP value of 8.8 psi on Stage 5 and knowing that Dow UF modules can operate until 30psi of TMP before requiring a CIP although a CIP is recommended once you reach 14.5 psi above the initial NTMP. 37 7.0 PERFORMANCE CRITERIA The performance of the module can be analyzed based on the performance criteria established for this Pilot Trial. Filtrate Turbidity: Filtrate turbidity was less than 0.1NTU except when a fiber breakage occurred. On Stage 1 on November 4th, 2014 a fiber breakage occurred resulting in a failed Integrity test and a spike on the Filtrate turbidity up to 0.49NTU. On November 5th the fiber was pinned and after that the turbidity was 100% of the time lower than 0.1NTU. CIP frequency: There was no need to perform a CIP with less than 30 days of operation. The CIPs that were performed were following the pilot schedule and phase transitioning. Specific Flux: The baseline Specific flux was established at 4.9gfd/psi after the first CIP on Stage 1. After the CIP on Stage 4 the Specific Flux returned to 4.9gfd/psi and after the CIP on Stage 5 the Specific Flux returned to 4.6gfd/psi. That means respectively 0% and 6.1% of decrease in Specific Flux relative to the baseline after each CIP. Integrity Tests: All Daily direct integrity tests (DITs) and DITs following CIPs were successful expect for some failures during commissioning of the pilot plant between 10/28/14 and 11/4/14 due to two fiber breaks and a leaking valve. After these fibers were pinned and the valve repaired, the membrane passed all integrity tests from 11/5/14 until the completion of the pilot study on 2/25/15. Fiber Breakage: As previously mentioned the module experienced two (2) broken fibers on the beginning of the operation. CEB frequency: CEBs were performed with frequency interval of no less than 1 day between CEBs. The actual frequency of the CEBs were: every 4 days for the Chlorine CEB and every 15 days for the acid CEB. Process Recovery: Monthly average process recovery was always higher than 95 percent. Once optimum operational parameters were established the recovery rate was calculated at 96.5%. 8.0 RECOMMENDATIONS The operation of the pilot and the changes performed to optimize operating conditions during the pilot study resulted in a sustainable operation, with sustainable fouling management while still achieving high membrane productivity. The last configuration used on the Optimization phase during Stage 1 showed the best results in terms of fouling control when Ferric Sulfate was being used on the WTP and the same operational configuration was confirmed sustainable on Stages 4, 5 and 6 when PACl was being utilized on the WTP. According to the results of this pilot study the parameters recommended for a full scale system are: 38 Filtration Flow: 34.5gpm Filtration Flux: 45gfd Filtration Time: 45 minutes BW flux: 70 gfd BW duration: 50 seconds Air Scour flowrate and duration: 9cfm and 40 seconds Forward Flush flow and duration: 45gpm and 20 seconds Chlorine CEB Frequency: Every 4 days at 500ppm with a 20 minute soaking Acid CEB Frequency: Every 15 days at 550ppm with 10 minute soaking The combination of the parameters above resulted in a system recovery of 96.5%. Normalized TMP was controlled by BW regimen and CEBs and after 32.7 days of runtime increased from 8.8 psi to 12.8 psi. Since the maximum TMP of operation for Dow modules is 30psi, the pilot results show that there was still room for TMP increase before water production output could be compromised. The CIP procedure returned the NTMP to 9.4 psi. Analyzing the TMP increase trend we can estimate and recommend a CIP procedure of every 3 months of operation.

Dixboro Rd., Ann Arbor, MI 48105 Description: Public Drinking Water Equipment Performance Challenge Testing Test Type: Qualification Job Number: J-00111435 Project Number: 9145690 Project Manager: Mike Blumenstein EXECUTIVE SUMMARY NSF International has determined by performance evaluation that the Dow Chemical, Dow Water and Process Solutions IntegraFlo™ DW102-1100 Ultrafiltration (UF) module has fulfilled the requirements of the NSF Certification Guideline for Public Drinking Water Equipment Performance. The IntegraFlo™ DW102-1100 UF module is therefore authorized to bear the NSF Mark for performance certification, as long as the Dow Chemical Company continues to meet the requirements of the NSF Certification Guideline, and the NSF General and Program-Specific Policies. NSF certification for performance requires the manufacturer to reset the manufacturing non-destructive performance test (NDPT) quality control release value (QCRV) to match the NDPT result measured by NSF that correlates with the observed LRVC-TEST. NSF has certified the IntegraFlo™ DW102-1100 UF module for Cryptosporidium removal efficiency, with a mean log removal value (LRVC-TEST) of 6.49 log10, and a minimum LRVC-TEST of 6.47 log10. The maximum certified feed flow is 50.2 gpm, which equals a flux of 70 gfd. Dow Chemical uses a pressure decay test as their manufacturing NDPT for the IntegraFlo™ DW102-1100 UF module. Based on the test data reported herein, NSF has set the NDPT QCRV to 0.06 pounds per square inch (psi) per minute for IntegraFlo™ DW102-1100 units that are NSF certified for performance. NSF has also tested the IntegraFlo™ DW102-1100 UF module for removal of pathogenic viruses using MS2 as a surrogate, following the same testing procedure. The virus LRVs ranged from 2.27 log10 to 2.65 log10. Report Authorization: Mr. C. Bruce Bartley, Manager, Public Drinking Water Equipment Performance NSF International 789 N. Dixboro Rd.

TEST REPORT 1 INTRODUCTION NSF International (NSF) is an independent third-party testing and certification organization accredited to ISO/IEC Guide 65, which applies to the requirements for bodies operating product certification systems, and ISO/IEC 17025, which contains the general requirements for the competence of testing and calibration facilities and organizations. NSF has created an NSF Certification Guideline for Public Drinking Water Equipment Performance (PDWEP). This certification guideline was created to serve drinking water stakeholders in the implementation of several US Environmental Protection Agency (EPA) rules to reduce the risk of exposure to water-borne pathogens in drinking water. Products certified to the guideline have met the performance testing and non-testing requirements described in the guideline document. The non-testing requirements include an annual audit of the production location. This audit monitors for any unauthorized design or material changes to the products, and also monitors the manufacturer’s internal quality control testing. NSF certification for performance requires the manufacturer to reset the manufacturing non-destructive performance test (NDPT) quality control release value (QCRV) to match the NDPT result measured by NSF that correlates with the observed LRVC-TEST. Testing of the Dow Water and Process Solutions IntegraFlo™ DW102-1100 Ultrafiltration (UF) membrane module was conducted in the NSF testing laboratory to measure log removals of Cryptosporidium,using Bacillus endospores as a surrogate, and pathogenic viruses using MS2 as a surrogate. The virus challenge tests were conducted to satisfy the requirement of the State of California to demonstrate virus removal of 90% or greater as an alternative treatment technology. All tests followed the product-specific challenge test requirements of the USEPA Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) (40 CFR §141.719). 2 INTEGRAFLO™ DW102-1100 UF MODULE DESCRIPTION The IntegraFlo™ DW102-1100 is a pressure driven UF module employing polyvinylidene fluoride (PVDF) hollow fiber membranes. The specifications and operating parameters are listed in Table 2-1. The IntegraFlo™ DW102- 1100 is certified to NSF/ANSI Standard 61, which establishes minimum public health related requirements for drinking water system components. Table 2-1.

TEST REPORT 3 METHODS AND PROCEDURES 3.1 Introduction The tests followed the procedures described in the test/QA plan specifically written for the IntegraFlo™ DW102- 1100. The challenge protocol in the test plan was adapted from the ETV Protocol for Equipment Verification Testing for Physical Removal of Microbiological and Particulate Contaminants , and the USEPA Membrane Filtration Guidance Manual (MFGM).Note that the MFGM references the ETV protocol as an acceptable protocol for testing membrane products according the to the USEPA requirements. The test/QA plan is available from NSF upon request. The challenge tests were conducted using Bacillus endospores as a surrogate for Cryptosporidium, and the MS2 coliphage virus as a surrogate for pathogenic viruses. See Section 3.2 for further discussion about the challenge organisms. Five modules supplied by Dow Chemical were tested. One module was tested per day, with separate challenge tests for each organism. The MS2 challenge tests were conducted first each day, followed by the Bacillus endospore tests. The tests were conducted in October of 2012. See Table 4-3 for the dates of each individual challenge test. 3.2 Challenge Organism and Challenge Concentration 3.2.1 Cryptosporidium Surrogate The IntegraFlo™ DW102-1100 modules were tested for removal of Cryptosporidium using endospores of the bacteria Bacillus atrophaeus (American Type Culture Collection (ATCC) number 9372, deposited as Bacillus subtilis var. niger). B. atrophaeus was selected as a surrogate for Cryptosporidium because it is a non-pathogenic bacterium, and also because of the high cost of suitable titers of live Cryptosporidium for testing at higher flow rates. The strain of B. atrophaeus used for testing yields orange colonies with a distinctive morphology on trypicase soy agar (TSA), so it can be distinguished from wild-type endospores that could be present as contamination.B. atrophaeus endospores are ellipsoidal (football shaped), with an average diameter of 0.8 μm, and an average length of 1.8 μm. See Appendix A for further discussion regarding the use of Bacillus endospores as a surrogate for Cryptosporidium. The LT2ESWTR calls for the maximum challenge concentration to be 6.5 log10 above the organism’s detection limit, which for the endospores was 1 CFU/100 mL. The goal for the B. atrophaeus challenges was to be able to measure log reductions greater than six, so NSF elected to targeted 6.5 log10 (3.16x106 CFU/100 mL) in order to account for less than 100% recovery of the spiked challenge organism concentration. 3.2.2 Pathogenic Virus Surrogate NSF employed the coliphage virus MS2 (ATCC 15597-Bl) as the surrogate for pathogenic viruses. MS2 is generally accepted as a virus surrogate for size-exclusion technologies due to its small size (22 to 26 nm). The MFGM references MS2 as an acceptable surrogate for pathogenic viruses because it is similar in size and shape to poliovirus and the hepatitis virus. The target MS2 challenge concentration target was also 6.5 logs (3.16x10 6 PFU/mL). 3.3 Test Apparatus The modules were tested in a system constructed specifically for these tests. The test system construction conformed to the requirements of the MFGM. See Figure 3-2 for a schematic diagram of the test system, and Figure 3-3 for a photo of the testing setup.

TEST REPORT Figure 3-3. Photo of Dow IntegraFlo™ DW102-1100 modules on test stand in NSF’s laboratory. The challenge organism challenge suspension was introduced into the feed water by intermittent injection during the challenge tests. Injection and mixing of the suspension into the feed stream followed the guidelines of the MFGM. Specifically, the total stock solution volume injected into the feed stream during each challenge test was between 0.5 and 2 percent of the total test solution volume, a chemical metering pump that delivered a steady flow of the challenge solution was used, and the injection port included a quill extending into the middle of the feed pipe. Also following the requirements of the MFGM, the feed sampling tap was located at least ten pipe diameters downstream of the injection point, and a static mixer was installed between the injection and feed sampling ports. The feed and filtrate samples were collected as grab samples from taps with quills extending into the middle of the pipe. The taps were metal so they were able to be flame-sterilized prior to sample collection. The grab sample volumes were 1 L for all Bacillus samples, and 125 mL for all MS2 samples.

TEST REPORT 3.4 Test Water Composition The test water was City of Ann Arbor tap water treated by activated carbon filtration to remove the disinfectant residual, and ultrafiltration to reduce suspended particles. The UF prefiltration step was downstream of the test water storage tank, as indicated in Figure 3-1, so as to remove suspended particles immediately prior to the test unit. Immediately prior to each challenge test, grab samples were collected from the feed tap for analysis of total chlorine, alkalinity, pH, temperature, total dissolved solids, total organic carbon, and turbidity. 3.5 UF Module Conditioning Prior to testing, both modules were installed together in the test tank, and sanitized and conditioned following a proprietary procedure provided by Dow Chemical. 3.6 Test System Sanitization The UF module conditioning procedure also served to santize the test system. The test system plumbing was also sanitized in between testing each module, by injecting a bleach solution into the feed stream to provide an appropriate CT for sanitization. After each sanitization period, the plumbing was flushed with dechlorinated tap water until no chlorine was detected in grab samples collected from the filtrate sample tap. Free available chlorine was also measured in the feed water immediately prior to each challenge test to confirm the water was free of chlorine. 3.7 UF Module Integrity Tests Immediately before and after each challenge test, each module underwent a pressure decay test following a procedure specified by Dow Chemical, to demonstrate continued membrane integrity. Thirty psi of air pressure was applied to the feed side of the module, and the pressure was recorded at Time 0 and at 20 minutes. This pressure meets the 3μm resolution requirement for the non-destructive performance test, as described in Section 4.2 of the MFGM. This pressure decay test procedure was also applied to the pressurized sections of the test rig plumbing for each day of testing, to account for any pressure loss from the plumbing, or to identify any significant pressure loss that had to be fixed. On each module tested, a valve was installed in the concentrate port cap to allow for release of the air introduced from the pressure decay tests. This ensured there was no air trapped in the module during the microbial challenge test. 3.8 Microbial Challenge Test Procedure Each of the IntegraFlo™ DW102-1100 modules was tested individually. The target flux for membrane operation was 70 gfd, which equals a flow of 50.2 gpm for the IntegraFlo™ DW102-1100 module. Immediately prior to each test, the module to be tested was backflushed for one minute at a flow rate of approximately 50 gpm, then forward flushed for at least five minutes, also at 50 gpm. Following the forward flush, the pre-challenge pressure decay was conducted per Section 3.7. After the integrity test was complete, the module under test was forward flushed for an additional five minutes to remove any remaining air from the pressure decay tests. At the beginning of this second forward flush, the air release valve installed on the concentrate port was opened to allow the air to escape. Toward the end of this second forward flush, two feed and two filtrate samples were collected. One sample of each process stream served as a negative control, while the second sample pair was spiked with the challenge organism to serve as positive controls. The testing engineer NSF International 789 N. Dixboro Rd. Ann Arbor, MI 48015, USA 1-800.NSF.MARK | +1-734.769.8010 | www.nsf.org FI20130131FINAL J-00111435 Page 6 Only authorized reports in their entirety may be distributed. This report does not represent authorization to use the NSF Mark. NSF Certification may be confirmed at www.nsf.org. The results of this report relate only to those items tested. TEST REPORT spiked these samples with measured aliquots of the challenge suspension immediately after sample collection, and the spiked samples were submitted to the NSF Microbiology Laboratory with the other samples from that challenge test. During the second flush the flow rate was adjusted, if necessary, to be at 50.2 gpm or slightly above, then the microbial challenge test immediately began. Each challenge test was approximately 35 minutes in length. The challenge organism suspension was injected into the feed stream at start-up, after 15 minutes of operation, and after 30 minutes of operation. The suspension was constantly stirred using a magnetic stir bar. The MFGM requires that feed and filtrate samples not be collected until at least three hold-up volumes of water spiked with the challenge organism have passed through the membrane, to allow for establishment of equilibrium (equilibrium volume). The hold-up volume is defined as the “unfiltered test solution volume that would remain in the system on the feed side of the membrane at the end of the test.” Dow gives the module volume as 11.36 gallons (gal). It was assumed that this volume is the total volume of the module, not just the volume on the feed side of the membrane. As such, its use for the hold-up volume added an additional safety factor for the equilibrium volume calculation. NSF calculated the hold-up volume of the test rig plumbing as approximately 5 gal, for a total of 16.36 gal for the entire test system, and just over 49 gal for the equilibrium volume. For each microbial challenge period, the challenge suspension was injected for at least one minute prior to initiation of sample collection, to provide at least 50 gal of spiked feed water. After at least one minute of organism injection, a grab sample was first collected from the feed sample tap, and then the filtrate sample was collected from the filtrate sample tap. The sample taps were flame sterilized prior to sample collection. Also, at least 100 mL was collected and discarded prior to sample collection to flush the taps. The sample volume was 1 L for all Bacillus samples, and 125 mL for all MS2 samples. Samples were collected directly into sterilized bottles provided by the NSF Microbiology Laboratory. After sample collection was complete, organism injection was stopped, and test water minus the challenge organism was pumped through the modules at the test flow rate until the next sampling point. 3.9 Analytical Methods A list of laboratory analytical methods can be found in Table 3-1. Single grab samples were collected for challenge organism numeration, and were analyzed in triplicate. Table 3-1.

TEST REPORT 4 RESULTS AND DISCUSSION For presentation of the challenge organism data in this chapter, the observed triplicate counts were averaged by calculating geometric means, as suggested for microbial enumeration data in SM 9020. The triplicate counts for each sample are provided in Appendix B. Geometric means <1 were rounded up to 1, unless all three triplicate analyses had no organisms found. The mean counts were log10 transformed for the purpose of calculating log removal values (LRV). The LT2ESWTR and MFGM specify that an LRV for the test (LRVC-TEST) be calculated for each module tested, and that the LRVs for each module are then combined to yield a single LRVC-TEST for the product. If fewer than 20 modules are tested, as was the case for this study, the LRVC-TEST is simply the lowest LRV for the individual modules. However, the rule does not specify a method to calculate LRVC-TEST for each module. Suggested options in the MFGM include: 1. Calculate a LRV for each feed/filtrate sample pair, then calculate the average of the individual sample point LRVs; 2. Average all of the feed and filtrate counts, and then calculate a single LRV for the module; or 3. Calculate a LRV for each feed/filtrate sample pair, select the LRV for the module as the lowest (most conservative of the three options). Options 1 and 2 give LRVC-TEST values that are either identical, or within a few hundredths of each other, so in this report, options 1 and 3 are used to calculate the Bacillus LRV for each module. Since the LT2ESWTR limits the challenge particle feed concentration to 6.50 log10, the Bacillus endospore feed counts above 6.50 log10 were reset to 6.50 log10 for calculating the LRVs. NSF has received approval from the USEPA for this approach. The MS2 feed counts were not reset for the LRV calculations. 4.1 B. atrophaeus Endospore Challenge Test Results The B. atrophaeus endospore challenge results are displayed in Table 4-1. For Modules 1, 3, and 4, one endospore per 100 mL was found in one of the four filtrate samples collected for each test. All of the log- transformed filtrate counts were 0.00, so the LRVs are simply a function of the feed counts. As discussed above in the Results and Discussion introduction, feed counts above 6.50 were reset to 6.50 for calculating the LRVs. Using Approach 1 for the LRVC-TEST calculation, the LRVC-TEST for the IntegraFlo™ DW102-1100 module is 6.49. Using Approach 3, the LRVC-TEST is 6.47. NSF International 789 N. Dixboro Rd.

TEST REPORT 4.3 Non-Destructive Performance Test Results The pre-test and post-test pressure decay test results are displayed in Table 4-3. The test rig plumbing that was pressurized during the tests was also pressure decay tested alone to check for any pressure loss from the plumbing that needed to be subtracted from the test pressure decay rates. No pressure loss from the plumbing was found, so no corrections to the decay rates are needed. The highest measured pressure decay rate for the Bacillus endospore challenge tests is 0.063 psi/min for Module 1. Therefore, for IntegraFlo™ DW102-1100 modules to be marked as NSF certified for performance, the new manufacturing NDPT QCRV is 0.06 psi/min. Table 4-3.

The flow and pressure readings were recorded onto bench sheets, and the fluxes were calculated from the flow data. The target flux for the tests was a minimum of 70 gfd. On four occasions, but only once for the Bacillus tests, the recorded flow rate was below the minimum required flow of 50.2 gpm by 0.1 or 0.2 gpm, resulting in fluxes below 70 gfd. All water chemistry measurements were within the expected ranges for this water source. NSF International 789 N. Dixboro Rd.

Careful adherence to the procedures ensures that the data presented in this report is of sound quality, is defensible, and is representative of the equipment performance. The primary areas of evaluation were representativeness, accuracy, and precision. All testing activities were conducted in accordance with the provisions of the NSF International Laboratories Quality Assurance Manual. 5.1 Sample Handling All samples analyzed by the NSF Chemistry and Microbiology Laboratories were labeled with unique identification numbers. All samples were analyzed within allowable holding times. 5.2 Chemistry Laboratory QA/QC The calibrations of all analytical instruments and the analyses of all parameters complied with the QA/QC provisions of the NSF International Laboratories Quality Assurance Manual. NSF International 789 N. Dixboro Rd. Ann Arbor, MI 48015, USA 1-800.NSF.MARK | +1-734.769.8010 | www.nsf.org FI20130131FINAL J-00111435 Page 12 Only authorized reports in their entirety may be distributed.

TEST REPORT The NSF QA/QC requirements are all compliant with those given in the USEPA method or Standard Method for the parameter. Also, every analytical method has an NSF standard operating procedure. 5.3 Microbiology Laboratory QA/QC 5.3.1 Growth Media Positive Controls All media were checked for sterility and positive growth response when prepared and when used for microorganism enumeration. The media was discarded if growth occurred on the sterility check media, or if there was an absence of growth in the positive response check. 5.3.2 Negative Controls For each sample batch processed, an unused membrane filter and a blank with 100 mL of buffered, sterilized dilution water was filtered through the membrane were also placed onto the appropriate media and incubated with the samples as negative controls. No growth was observed on any blanks. 5.3.3 Documentation All laboratory activities were documented using specially prepared laboratory bench sheets and NSF laboratory data reports. Data from the bench sheets were entered into a spreadsheet. The spreadsheet was used to calculate the geometric means and log10 reductions. 5.4 Data Quality Indicators The quality of data generated for this certification is established through four indicators of data quality: representativeness, accuracy, precision, and completeness. 5.4.1 Representativeness Representativeness is a qualitative term that expresses “the degree to which data accurately and precisely represent a characteristic of a population, parameter variations at a sampling point, a process condition, or an environmental condition.” Representativeness was ensured by consistent execution of the test protocol for each challenge, including timing of sample collection, sampling procedures, and sample preservation. Representativeness was also ensured by using each analytical method at its optimum capability to provide results that represent the most accurate and precise measurement it is capable of achieving. 5.4.2 Accuracy Accuracy was quantified as the percent recovery of the parameter in a sample of known quantity. Accuracy was measured through use of both matrix spikes of a known quantity and certified standards during calibration of an instrument. The following equation was used to calculate percent recovery: Percent Recovery = 100 u [(Xknown –Xmeasured)/Xknown] where: Xknown = known concentration of the measured parameter Xmeasured = measured concentration of parameter Accuracy of the benchtop chlorine, pH, and turbidity meters was checked daily during the calibration procedures using certified check standards. Alkalinity and TDS were analyzed in batches with samples from other NSF testing activities. Certified QC standards and/or matrix spikes were run with each batch. NSF International 789 N. Dixboro Rd. Ann Arbor, MI 48015, USA 1-800.NSF.MARK | +1-734.769.8010 | www.nsf.org FI20130131FINAL J-00111435 Page 13 Only authorized reports in their entirety may be distributed. This report does not represent authorization to use the NSF Mark. NSF Certification may be confirmed at www.nsf.org. The results of this report relate only to those items tested. TEST REPORT The NSF Laboratory Quality Assurance Manual establishes the frequency of spike sample analyses at 10% of the samples analyzed for chemical analyses. Laboratory control samples are also run at a frequency of 10%. The recovery limits specified for the parameters in this verification, excluding microbiological analyses, were 70-130% for laboratory-fortified samples and 85-115% for laboratory control samples. 5.4.3 Precision Precision refers to the degree of mutual agreement among individual measurements and provides an estimate of random error. For each challenge test, one set of challenge organism samples was collected in duplicate for precision analysis. Samples for alkalinity and TDS analysis were submitted to the NSF Chemistry Laboratory, where they were analyzed in batches with other samples. For these batches, at least one out of every ten samples was analyzed in duplicate. Duplicate municipal drinking water samples were analyzed for pH, total chlorine, and turbidity as part of the daily instrument calibration process. Precision of duplicate analyses was measured by use of the following equation to calculate relative percent deviation (RPD): 200 21 21 u SS SSRPD where: 1S = sample analysis result; and 2S = sample duplicate analysis result. Acceptable analytical precision was an RPD of 30%. All water chemistry duplicate analyses had an RPD of 30% or less, because NSF’s policy is to not report results from an analytical run if the RPD too high. RPDs were also calculated for the log-transformed results of the duplicate Bacillus and MS2 sample pairs (data not shown). All microbial duplicate sample pairs had RPDs of 7.8% or less.

TEST REPORT Appendix A Bacillus Endospores as a Surrogate for C. parvum Oocysts The EPA LT2ESWTR allows the use of a surrogate for C. parvum, provided the surrogate is conservative. The EPA MFGM specifically discusses Bacillus subtilis as a surrogate, but states “Because there is limited data currently available regarding the use of Bacillus subtilis in membrane challenge studies, a characterization of this organism would be necessary to determine whether it could be used as a Cryptosporidium surrogate…” The MFGM also states “Based on the size…Bacillus subtilis could potentially be considered a conservative surrogate…pending a comparison of other characteristics (e.g., shape, surface charge, etc.)…” 1. Organism Size and Shape C. parvum is spherical in shape, while Bacillus endospores are ellipsoidal in shape (football shaped). C. parvum has a diameter of 4-6 μm. Bacillus endospores are approximately 0.8 μm in diameter, and 1.8 μm in length. Therefore, Bacillus endospores are a conservative surrogate for C. parvum, no matter what the orientation of the endospore is when it impacts the test membrane. Baltus et. al. (2008) studied membrane rejection of bacteria and viruses with different length vs. diameter aspect ratios. They theorized, based on a transport model for rod-shaped particles, that rejection would improve as the aspect ratio (length vs. diameter) increased for a fixed particle volume. However, their experimental results contradicted this, with similar rejection rates for particles with a range of aspect ratios. The model assumed that particles would impact the membrane with equal frequency for all particle orientations. They theorize that instead, an end-on orientation was favored for transport of the particles in the water stream. They concluded that microorganism removal by membranes could be conservatively estimated using only the rod diameter in transport models. These findings add an additional safety factor to using Bacillus endospores as a surrogate for C. parvum. 2. Electrophoretic Mobility and Isoelectric Point A suitable surrogate should have a surface charge similar to C. parvum, as measured through the isoelectric point and electrophoretic mobility (EPM). The isoelectric point is the pH at which the particle has a neutral surface charge in an aqueous environment. Below this point the particle has a net positive charge, above it a net negative charge. Many studies have pegged the isoelectric point of C. parvum between pH values of 2 and 4, thus it would have a negative surface charge in the neutral pH range. The isoelectric point can be found by measuring the EPM of the particle at various pH values. The pH where the EPM is zero is classified as the isoelectric point. Lytle et. al. (2002) measured the EPM of both C. parvum and B. subtilis endospores in solutions of increasing buffer concentration (0.915 millimolar, mM, 9.15 mM, and 91.5 mM KH2PO4). They found that increasing the buffer concentration also increases the EPM toward a positive value. In 0.915 mM solutions at pH values between 7 and 8, they observed EPM of approximately -2.2 to -2.6 μm cm V-1 s-1 for C. parvum, and -1.9 to -2.2 μm cm V-1s-1 for B. subtilis. For B. subtilis, the researchers did not measure an isoelectric point at any buffer concentration. For C. parvum, they did find an isoelectric point at a pH around 2.5, but only for the 9.15 mM solution. For both organisms, the 0.915 mM solution generally gave lower (more negative) EPM values than the solutions with higher buffering capacity. NSF International 789 N. Dixboro Rd.

Aggregation The NSF Microbiology Laboratory microscopically examined a sample of the B. atrophaeus stock solutions purchased for the tests. The sample was suspended in sterile, buffered, deionized water and stirred at moderate speed for 15 minutes. The estimated cell density was 1x10 9 CFU/100 mL, which is approximately 100 times higher than the suspensions injected into the pilot units to challenge the UF membranes. Figure B-1 is a photograph of the B. atrophaeus endospores in the sample. The magnification is 1000x oil immersion with differential interference contrast microscopy. No evidence of endospore aggregation was found. Figure A-1. Mono-dispersed B. atrophaeus endospores used for challenge tests. NSF International 789 N. Dixboro Rd.

Worth, TX with Pentair’s Aquaflex 55 UF module was successful. Stable operation was demonstrated while treating BAF effluent directly during each of the four stages as outlined within this report. We therefore recommend the following key operating parameters for the planned expansion of the EMWTP. The demonstrated and expected water quality is noted below as well. Recommended key operating parameters ¾ Filtration flux: 45 gfd ¾ Filtration time: 50 min at 45 gfd ¾ Recovery: >95% ¾ CEB frequency: Daily or after 27 filtration cycles ¾ CEB scheme: o CEB1A: 200 ppm NaOCl at pH 12 (pH adjusted with NaOH) o CEB1B: acid CEB at pH 2 (pH adjusted with H2SO4 or HCl) ¾ DIT: Daily or as required by TCEQ UF filtrate water quality ¾ Filtrate turbidity: <0.020 NTU ¾ LRV of Cryptosporidium: >4.0 log10 In closing, Pentair would like to thank Jerry McMillion and his staff at EMWTP that participated in making the testing such a success. Pentair would also like to thank Dr. Christopher Boyd and Alan Plummer Associates for their assistance and efforts in coordinating the study. Without their input, conscientious assistance and guidance, the pilot trial would not have been such a success. Pentair would also like to thank Julie Harn and Harn RO for all their assistance and for the use of their well-equipped and capable UF Pilot #5. Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 5 of 25 Revision 2, date 27-April-2015 2 Introduction In June of 2014, Pentair X-Flow was invited to participate in a pilot study at the Eagle Mountain Water Treatment Plant (EMWTP) to evaluate pressure driven hollow fiber UF as a suitable treatment process to polish the effluent from the existing process outlined below. The scope of the pilot study was to evaluate BAF filtered water as a suitable feed source to UF to meet drinking water standards established by TCEQ and to establish design criteria for the planned future expansion of the EMWTP by adding UF to the existing treatment scheme. The pilot study was scheduled to cover six stages. The first three stages would evaluate FeSO4 as the coagulant and PACl would be used for the final three stages. A seventh optional stage was pending in the event additional information was needed. However, the study was cut short and limited to only four stages: Stage 1 – Optimization (FeSO4), Stage 4 - Optimization (PACl), Stage 5 – 30-Day Demonstration Run and Stage 6 – 10-Day verification Run. Stages 2 and 3 were omitted and Stage 7 was not needed. The UF performance criteria set for the project are listed below: 1. UF Filtrate turbidity must be maintained less than 0.1 NTU 100% of the time. 2. CIP interval cannot be less than 30 days between CIPs. 3. Maximum 10% decrease in the (20 deg C) normalized specific flux relative to the baseline clean water flux conditions as measured following each CIP for the entire pilot duration. 4. Pass daily direct integrity tests (DIT) and DITs following CIPs that are performed in accordance with the LT2ESWTR and TCEQ requirements. 5. Fiber breakage for the pilot study of no more than two broken fibers per pilot system excluding any broken fibers that may occur during the two week startup and testing period. 6. CEB frequency interval of no less than 1 day between CEBs. 7. Monthly average process recovery no less than 95%.

The UF pilot operates automatically based on operator adjustable settings and includes alarms and provisions for remote access for start/stop operation, control of key process parameters, data uploads and other key functions. The UF pilot is fully instrumented to monitor performance and to automatically detect abnormal operation including losing feed flow and low feed and filtrate tank levels. A self-cleaning strainer is located on the UF skid to remove particles larger than 300 micron upstream of the UF membranes. The main Operator responsibilities are to monitor pilot operation, collect operational data and replenish pre-treatment and CEB chemical tanks as needed. The CEB chemical usage is dependent on operational settings. However, the chemical tanks are sized to require replenishment approximately once per week for typical settings. The following data can be monitored and recorded by the UF pilot unit: x Feed, Filtrate and Concentrate pressure x Feed Flow x Transmembrane Pressure x Filtrate flux x Raw water temperature x Temperature corrected flux x Specific flux/ Permeability x Operational mode x Alarms x Feed and Filtrate turbidity x pH/ORP x Conductivity x Direct integrity test system (DITS) pressures and calculated pressure decay The pilot unit is equipped with the following instrumentation: Flow x Feed: Yokogawa Mag Meter x Filtrate: Yokogawa Mag Meter x Backwash/CEB: Yokogawa Mag Meter Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 8 of 25 Revision 2, date 27-April-2015 Pressure x Lower Feed/Retentate: Yokogawa Transmitter & Gauge x Upper Feed/Retentate: Yokogawa Transmitter & Gauge x Filtrate/Backwash Feed: Yokogawa Transmitter & Gauge x Feed Strainer Inlet/Outlet: Wika Transmitter Turbidity x Feed: HF Scientific White Light x Filtrate: Hach 660sc Laser pH & Conductivity x Filtrate/Backwash/CEB: Rosemount Analytical Level x Feed Tank: Wika Submersible x Filtrate Tank: Wika Submersible The pilot equipment was installed the week of Oct 20, 2014 and commissioned fitted with (1) Aquaflex 55 module (SN 12DA5289). The module was flushed with city water and conditioned for use with a 200 ppm NaOCL CEB with a 10 minute soak. During the commissioning period, the starting normalized CWP was determined to be 30 gfd/psi. 3.2 Modes of Operation The pilot was programmed for normal dead-end service as outlined below. 3.2.1 Filtration During filtration, water was fed to the top endcap 100% of the time. The permeate was drawn off thru the single permeate port on the top endcap. Filtration continued until the filtration timer timed out. Once the timer timed out, filtration was terminated and the hydraulic cleaning was initiated. Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 9 of 25 Revision 2, date 27-April-2015 Figure 3.1 Filtration 3.2.2 Hydraulic Cleaning – FF Top Down Step 1 of the hydraulic cleaning (HC) was the forward flush from the top down. The feed pump continued to run with a setpoint of 14.5 gpm while the bottom waste outlet vale opened and the permeate valve closed. During this step, solids were flushed from the fibers and the bottom endcap. This step is necessary to prevent the buildup of solids in the bottom endcap. After 5 seconds, the sequence advanced to the next step. Figure 3.2 Hydraulic Cleaning – FF Top Down 3.2.3 Hydraulic Cleaning – FF Bottom Up Step 2 of the HC was the forward flush from the bottom up. The feed pump continued to run while the bottom feed and top waste outlet valves opened. The top feed and bottom waste Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 10 of 25 Revision 2, date 27-April-2015 outlet valves closed at the same time. During this step, solids were flushed from the fibers and out thru the top endcap. After 10 seconds, the sequence advanced to the next step. Figure 3.3 Hydraulic Cleaning – FF Bottom Up 3.2.4 Hydraulic Cleaning – FF with BW Step 3 of the HC was the forward flush combined with the backwash. The feed pump continued to run while the backwash inlet valve opened. Once the backwash valve was open, the backwash pump was started with a setpoint of 60.5 gpm. There was an 8-10 second delay before the backwash flow rate was detected by the follow meter as a result of the delayed pump start. During this step, any cake layer formed on the inside surface of the membrane was collapsed and flushed from the fibers and out thru the top waste outlet valve. After 28 seconds, the sequence advanced to the next step. Figure 3.4 Hydraulic Cleaning – FF with BW Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 11 of 25 Revision 2, date 27-April-2015 3.2.5 Hydraulic Cleaning – FF to Finish Step 4 of the HC was the final forward flush. The feed pump continued to run while the backwash inlet valve closed and the backwash pump was stopped. During this step, any trace solids were flushed from the fibers and skid piping to drain while the backwash pump shut down. After 3 seconds, the sequence was completed and the system was ready for the next step in the process. If the BW counter had not yet reached 27, the system returned to filtration. If the BW counter had reached 27, the CEB was initiated instead. Figure 3.5 Hydraulic Cleaning – FF to Finish 3.2.6 CEB – Chemical Dosing The CEB immediately followed the 27th backwash. The feed pump was stopped and the bottom feed inlet valve closed while the backwash pump continued to run at a reduced speed to achieve the CEB1A/B dilution flow rate setpoint of 27.1 gpm. The desired metering pump(s) was energized and chemical was injected into the BW stream and washed into the membrane. After 67 seconds, the sequence advanced to the next step. Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 12 of 25 Revision 2, date 27-April-2015 Figure 3.6 CEB – Chemical Dosing 3.2.7 CEB – Chemical Soak During the soak, all valves were closed and pumps remained off while the membrane soaked in either hypo/caustic (CEB1A) for 35 minutes or H2SO4 acid (CEB1B) for 15 minutes. The sequence advanced to the next step after the soak timer timed out. Figure 3.7 CEB – Chemical Soak 3.2.8 CEB – Rinse The top and bottom waste outlet and backwash inlet valves were opened and the backwash pump started with a setpoint of 27.1 gpm. During the rinse step, all traces of the CEB chemical were rinsed from the membrane and skid piping. After 160 seconds, the system was rinsed and the sequence advanced to the next step. If the hypo/caustic CEB1A was just completed, the sequence Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 13 of 25 Revision 2, date 27-April-2015 advanced to the chemical dosing step for the acid CEB1B. If the acid CEB1B was just completed, the system returned to service. Figure 3.8 CEB – Rinse 3.2.9 PDT The daily direct integrity test (DIT) was completed at or near the start of a filtration cycle. The DIT method used was the pressure decay test (PDT). In order to initiate the PDT, the system was switched off to enable the PDT. Once available, the PDT button was pressed and the test was started. Step 1 of the PDT was used to evacuate water from the feed side of the membrane. Air was introduced to the top feed header piping while the permeate valve was open. Under pressure, water in contact with the feed side of the membrane was forced across the membrane to the permeate side. It typically required about 5 minutes to evacuate the water from the feed side of the membrane and stabilize the feed-side air pressure. Once the pressure had stabilized, the air supply valve was closed. The PLC began recording the feed-side pressure during Step 2 of the PDT in order to determine the decay rate. The PLC tracked the feed-side pressure over the next 5 minutes. The system was depressurized during Step 3. Once depressurized, the system was available to returned to service. Before the system returned to service following a PDT, the system completed a Fill and Vent Sequence. 3.2.10 Fill and Vent Sequence At the end of the PDT, the feed side of the membrane was still filled with air. This air had to be purged from the system before the system could return to service. This was accomplished by Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 14 of 25 Revision 2, date 27-April-2015 feeding the module thru the bottom endcap at a reduced feed rate of 10 gpm for 120 seconds. During this time, air was vented out thru the top of the module thru the top waste outlet valve and permeate valve. Level switches located in the top feed and permeate headers were used to confirm all the air was vented from the system before returning to service. Once filled and devoid of air, the system advanced to forward filtration mode. 3.3 Stage 1 – Optimization (FeSO4) The pilot study officially began with Stage 1 on Nov 4, 2014. Stage 1 was continued thru the coagulant change over (Ferric sulfate -> PACl) that was completed on Dec 4. The pilot study officially resumed with Stage 4 on December 15. Stage 4 concluded Jan 5 after roughly 57 days of operation. Throughout the optimization Stages 1 and 4, operating conditions were modified in order to optimize capacity (flux), recovery and cleaning frequency. When stable operation was reached, the flux was increased to test for greater capacity. Throughout this discussion, normalized specific flux/permeability is referenced. Stage 1 began utilizing chlorinated backwashes. Stage 1.1 was maintained from November 4 thru November 11 and started with a permeability of ~25 gfd/psi. After 1 week, the permeability had dropped to ~16 gfd/psi, where it appeared to stabilize; ~16 gfd/psi after the backwash and ~12 gfd/psi right before the backwash for roughly 42 hours of operation. One single hypo CEB was initiated at the end of the week and the permeability was restored to 21 gfd/psi after a 10 minute soak in 200 ppm NaOCl. The chlorinated backwashes showed promise, but given they were not favored, they were discontinued and not revisited during the rest of the pilot study. Stage 1.2 picked up where the chlorinated backwashes were terminated; 50 gfd with a 55 minute filtration runtime. Stage 1.2 operated from November 12 thru November 18. Chlorinated CEBs were scheduled after every 26 filtration cycles. During this stage, operation was interrupted by a few low level alarms and significant time (>78 hrs) was lost. Alarms logged during Stage 1 are detailed in Table 3.7 located Page 17. Stable operation was not achieved during Stages 1.3 and 1.4, but the system was allowed to operate while plans to modify the CEB strategy were made. On November 24 and 25, the pilot was reconfigured to allow for acid CEBs. During this site visit, the system was down for about 22 hours. The three chemical day tanks were dumped and the chemicals refreshed with the chemicals listed in Table 3.1. These pump settings and day tank concentrations were used throughout the remainder of the pilot study. The NaOCl and H2SO4 were supplied by the city at 12% and 25% by weight respectively. NaOH was supplied by the city at 50% by weight, but it was diluted (50/50) with city water to 25% to avoid any possible delays due to freezing while running thru winter.

CEB1A was completed daily and CEB1B was completed immediately after CEB1A every other day. The system appeared to be stable at 20 gfd/psi with these settings, so the flux was increased from 45 to 50 gfd for Stage 1.6. The system continued to run well during Stage 1.6 after the flux was increased to 50 gfd with the same CEB schedule as Stage 1.5. The permeability appeared to be stable at ~15 gfd/psi for the nearly 3 days of operation, so the flux was bumped up to 55 gfd for Stage 1.7. During Stage 1.7, the system did not appear to be stabilize and the low permeability led to the pilot’s first high TMP alarm set at 15 psi. The flux was therefore reduced from 55 to 50 gfd for Stage 1.8. Stage 1.8 was completed at 50 gfd but did not yield favorable or stable operation, so the flux was dropped further to 45 gfd for Stage 1.9. Stage 1.9 operated at 45 gfd for two days at the tail end of the FeSO4 treatment phase. Even though the permeability reaches low levels during the two days of operation, the performance seemed stable, so these settings were carried over into Stage 4.1. 3.4 Stage 4 – Optimization (PACl) Stage 4.1 was the start of the PACl treatment and operating settings were carried over from Stage 1.9. Stage 4.1 ran from December 15 thru December 22 with stable performance, so one final run at 50 gfd was made during Stage 4.2. Stable operation was not achieved during Stage 4.2 while running at 50 gfd with a 50 minute runtime and a high TMP alarm was triggered near the end of the stage, so the flux was once again dropped to 45 gfd where the system operated for the rest of the pilot study. Stage 4.3 was completed at 45 gfd with a filtration runtime of 55 minutes to help recovery. The system was still not stable, so the runtime was reduced to 50 minutes while holding the flux at 45 gfd for Stage 4.4. Stage 4.4 was run up until the optional CIP was initiated. With Stage 5 approaching and more stable operations needed, the CEB soak times for CEB1A and CEB1B were increased from 10 to 15 Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 16 of 25 Revision 2, date 27-April-2015 minutes to achieve greater permeability recovery during CEBs. More effective CEBs and reduced fouling helped, but more was needed in order to meet the recovery and cleaning interval limits set for the pilot study. We also logged another TMP alarm during this stage. Given the recent TMP alarms logged during the past few stages, the operating settings noted in Table 3.2 were selected for Stage 5, the 30-Day Demonstration Run. The primary changes from Stage 4.4 include increasing the CEB1A soak time from 15 to 35 minutes and CEBs (CEB1A and CEB1B) were scheduled to be completed back to back for maximum permeability recovery. The CEB counter was also increased to 27 to ensure a CEB schedule not less than once per day and >95% recovery as required. These final settings proved to be effective during Stages 5 and enabled us to meet the performance criteria set for the pilot study.

During this window, we elected to complete a CIP to gain information ahead of the mandatory CIP to follow Stage 5. This CIP was initiated January 5 and completed January 6. Prior to initiating the CIP, a CEB1A followed by a CEB1B was completed. The results of the CEBs are noted in the Table 3.3.

Both chemicals were supplied by the city. The solution was thoroughly mixed before recirculating it thru the module. During the CIP, the solution was recirculated thru the module for 2 hrs, then a static soak for 2 hours, then recirculated for 2 additional hours before allowing the module to soak overnight. During the CIP, the membrane was in contact with the citric acid/SBS solution for a total of 22 hours before it was drained and the module rinsed. When the module was returned to service at 45 gfd, the normalized CWP was determined to be 28.9 gfd/psi. The citric acid/SBS CIP conditions are noted in Table 3.4 and the results in Table 3.5.

Given the pressure feeding the inlet valve remained somewhat constant, the fill valve must have been bumped at some point, causing the fill rate to be reduced. The low level alarms were addressed by eventually increasing the fill rate, but the low level alarms did return during Stage 5. The High TMP alarms were addressed during Stages 1 and 4 only by executing CEBs before returning the pilot to service. 3.5 Stage 5 – 30-Day Demonstration Run The official start of Stage 5 was January 8 and the run concluded February 9 after more than 31 days of stable operation. The operating parameters selected at the end of Stage 4 and highlighted in Table 3.2 were utilized during Stage 5. Filtration was maintained at 18.5 gpm (45 gfd). The average monthly recovery was 95.4% (Appendix F). The filtrate turbidity was maintained less than or equal to 0.017 NTU 100% of the time with an average of 0.015 NTU (Table 2). Daily CEBs consistently returned the typical permeability to 23-25 gfd/psi (Figure 1) with an average permeability of 13.7 gfd/psi (Table 1) during the run. Daily PDTs passed with a minimum LRV of 4.20 (∆P = 0.0990 psi/min) and a maximum of 4.89 (∆P = 0.0198 psi/min). The average LRV achieved during Stage 5 was 4.62 (Table 2). Stage 5 concluded February 9, 2015 at 11:22 PM. During Stage 5, the following alarms occurred resulting in a total downtime of 17.1 hours.

The TMP alarm on 1/16 was acknowledged and reset by plant personnel. The TMP alarm on 2/5 was reached with two BW cycles remaining before the normally scheduled CEB. The alarm was reset and the unit returned to service. The unit ran normally and reached the CEB without shutting down. The feed tank fill rate was adjusted again by plant personnel and no other low feed tank level alarms occurred before the pilot study concluded. Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 19 of 25 Revision 2, date 27-April-2015 The BW pump high discharge pressure alarm occurred during a CEB when a valve failed to open. The alarm was reset and the system was monitored thru the CEB, which proceeded without additional issues. The minimum starting pressure was not reached during the PDT on 1/28. The alarm was reset and the PDT restarted and it proceeded normally without further alarms. The high feed turbidity alarm on 2/8 was the first of several that would occur later in Stage 6. It appears the feed turbidity had begun to drift sometime in January and the turbidimeter required recalibration. This was confirmed by plant (BAF effluent) turbidity readings which did not exceed 0.23 NTU throughout Stages 5 and 6. 3.6 Mandatory CIP (completed Feb 10, 2015) During the course of the pilot, the CEBs were very effective for long-term permeability maintenance. The normalized permeability was typically returned to 23-25 gfd/psi following each CEB during the more than 31 days of continuous operation during Stages 5. The CIP was not needed for continued stable operation and no CIPs were used during Stage 5. However, as part of the protocol, a CIP was required following Stage 5 and before Stage 6 could begin. The mandatory CIP required only one step to achieve greater than 90% of the starting CWP as required by the protocol. Two additional cleanings were completed to determine if additional gains were possible and the details are presented below. The CIP cleaning solution was prepared in the feed tank. Given the feed tank contained city water already, the tank was not drained and cleaned, it was just drained to the 50 gallon mark, which is the volume required to keep the feed pump flooded during the course of the CIP. Chemical make-up: The feed pump was used to mix the cleaning solution in the feed tank by recirculating the solution thru valve V14, bypassing the membrane and returning to the feed tank thru the manual Cleaning Return valve on the end of the skid. In this way, water was drawn from the lower side of the tank and returned to the tank above the liquid level in the tank. This turned the tank volume over well and provided for good mixing. The speed of the pump was manually adjusted (by changing the frequency) to achieve a flow rate of 25-35 gpm to facilitate mixing. With an established flow rate of 25-35 gpm, the desired chemicals were slowly added to the tank. The tank was allowed to recirculate for a several minutes to ensure the chemicals were completely mixed. The final CIP solution concentrations are based on the fact that the system was not drained and contained 25 gallons of water. This system’s hold-up volume diluted the CIP solutions to the desired target strength. Chemical recirculation: With the cleaning solution mixed and ready, the flow rate was reduced to 6 gpm and the cleaning solution was fed to the bottom endcap. The CIP solution flowed up thru the lumen of fibers and returned to the feed tank from the feed port on the top endcap. Valves Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 20 of 25 Revision 2, date 27-April-2015 V1, V6, V7 and the manual Clean Return valve on the end of the skid were open and the bypass valve V14 was closed during this time. Rinse: At the end of the CIP, the pump was stopped and the feed tank was drained and rinsed. Once the tank was rinsed, it was filled with city water to begin rinsing the skid piping and module. Fifty gallons of water were used from the feed tank to rinse the skid feed piping and to begin rinsing the module. The final rinse was accomplished using a 70 second backwash at 60.5 gpm with UF filtrate. This ensured the permeate side of the module was fully rinsed. Hypo/caustic CIP: With the feed tank recirculating at 25-35 gpm, 542 ml of 50% NaOH and 394 ml of 12% NaOCl were slowly added to the feed tank filled with 50 gallons of city water. Once mixed, the hypo solution was redirected thru the module. The solution was allowed to recirculate thru the module for 120 minutes, after which the solution was drained and the module rinsed. A sample of the CIP solution was pulled from the feed tank and the solution was clear and basically colorless. When the module was returned to service at 50 gfd, the normalized CWP was determined to be 28.5 gfd/psi, which was greater than the min 90% required by the protocol (90% x 30 gfd/psi = 27 gfd/psi min). The hypo/caustic CIP conditions are noted in Table 3.9 and the results in Table 3.10 Table 3.9 Hypo/caustic CIP Conditions Parameter Start Finish Time (in recirculation) Temperature Feed flow rate Permeate flow rate Feed pressure Permeate pressure pH ORP 11:45 12.5 deg C 6.1 gpm 0 gpm 2.67 psig 2.30 psig 12.5 432 mv 13:56 12.7 deg C 6.0 gpm 0 gpm 2.73 psig 2.31 psig 12.7 436 mv Table 3.10 Hypo/caustic CIP CWP Recovery CIP Specific Flux Normalized Specific Flux Recovery Start End Start End % of 30 gfd/psi Hypo/Caustic CIP 20.3 21.6 26.4 28.5 95.0 Extended Acid CEB: Given the acid CEB had been effective and we just completed a high pH cleaning, a standard acid CEB was completed to determine the full effects of the hypo/caustic CIP. Filtration was terminated without a backwash (since it had only been in service for a few minutes) and a normal acid CEB was initiated. Sulfuric acid was injected during the normal wash-in step of the CEB and the final pH reached was 1.7. The membrane was allowed to soak in the acid for 60 min. The acid was rinsed from the module using a 70 second backwash at 60.5 gpm with UF filtrate. When the module was returned to service at 50 gfd, the normalized CWP was determined to be 30.5 gfd/psi, which is 100% of the target. The acid CEB conditions are noted in Table 3.11 and the results in Table 3.12.

The solution was thoroughly mixed before recirculating it thru the module for 2 hrs. After 2 hours, the solution was drained and the module rinsed. When the module was returned to service at 50 gfd, the normalized CWP was determined to be 30.1 gfd/psi. No improvement over the previous extended acid CEB was realized with the citric acid and therefore this cleaning was not beneficial or needed under these circumstances.

The operating parameters utilized during Stage 6 were carried over from Stage 5 and no changes were made. Filtration was maintained at 18.5 gpm (45 gfd). The average monthly recovery was 95.4%. The filtrate turbidity was maintained less than or equal to 0.015 NTU 100% of the time with an average of 0.014 NTU (Table 2). Daily CEBs consistently returned the typical permeability to 23-25 gfd/psi (Figure 1) with an average permeability of 15.5 gfd/psi (Table 1) during the run. Daily PDTs passed with a minimum LRV of 4.29 (∆P = 0.0792 psi/min) and a maximum of 4.89 (∆P = 0.0198 psi/min). The average LRV achieved during Stage 3 was 4.56 (Table 2). During Stage 6, the following alarms occurred resulting in a total downtime of 7.4 hours.

It was noted, the rotameter feeding the feed turbidimeter was very dark and fouled. This is the likely cause for the drift since the flow rate needed to keep the sample chamber fresh was not maintained. The pilot study concluded February 25, 2015 at 1:30 AM after logging more than 2462 hrs (102 days) of operating data. Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 23 of 25 Revision 2, date 27-April-2015 4 Results The paragraphs below highlight the results as they relate to the performance criteria set for the project. Each performance criteria was met as noted below. Each item is discussed separately and in the order listed in Section 2. 4.1 UF filtrate turbidity less than 0.1 NTU 100% of the time The filtrate turbidity was maintained less than 0.1 NTU 100% of the time the unit was in normal filtration mode. The typical filtrate turbidity was less than 0.020 NTU throughout the study as shown in Figure 3. The filtrate turbidity did reach 0.224 NTU during the mandatory CIP when cleaning chemicals flowed past the in-line instruments, but it returned to normal (<0.02 NTU) when the system was returned to normal filtration. 4.2 CIP interval no less than 30 days between CIPs The CIP interval was met given no CIPs were used during Stage 5 and 6. Only two CIPs were completed during the pilot study. No other CIPs were initiated or completed. 1. CIP#1: The first CIP was voluntary and it was completed ahead of Stage 5. The CIP was completed to determine the extent of any possible iron fouling lingering from Stage 1. It was determined iron fouling was not an issue. 2. CIP#2: The second CIP was discussed in Section 3.6. This CIP was not required to maintain operation during Stages 5 or 6. The second CIP was completed to determine the CWP recovery following Stage 5 as required by the protocol. 4.3 CIP clean water permeability recovery not less than 90% of the starting CWP The starting normalized CWP was determined to be 30 gfd/psi. Following the hypo/caustic CIP completed as part of the mandatory CIP after Stage 5, the normalized CWP was determined to be 28.5 gfd/psi, which is greater than 90% of the starting CWP (Table 3.10). The subsequent acid CEB restored the starting CWP to 30 gfd/psi or 100% of the starting point (see Table 3.12). 4.4 Pass Daily DITs The pressure decay test method was the DIT used throughout the study. All PDTs passed and at no time during the study did the decay rate exceed 0.10 psi/min, which is well below the 0.1552 psi/min UCL for the system (Table 2 and Figure 8). Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 24 of 25 Revision 2, date 27-April-2015 4.5 Fiber breakage During the course of the entire pilot study, there were zero broken fibers and therefore zero repairs made. Several DITs were witnessed by plant personnel and Harn RO and Pentair rep’s during commissioning and other site visits for CIP and other maintenance. At no time during the study did the PDT fail and no bubbles were observed or reported in the site window located in the permeate piping immediately leaving the module. This indicates not only did every DIT pass, but there were also zero integrity breaches large or small and the membrane remained completely intact throughout the entire study. 4.6 CEB frequency interval no less than 1 day between CEBs Theoretically, CEBs were completed every 1.002 days based on step times loaded in the PLC program. This does not account for the mode-to-mode sequencing delays. In practice, the CEBs were completed every 24.5 hours, meaning the CEBs were completed roughly 30 minutes later in the day each day provided there were no unscheduled shutdowns due to alarms (see Appendix F). 4.7 Monthly average process recovery no less than 95% The monthly average recovery for Stage 5 was 95.40%. The overall recovery during Stage 5 was 95.31% including the mandatory CIP and extended acid CEB required to achieve 100% of the starting normalized CWP. These calculations is detailed in Appendix F. Pentair Flow and Filtration Solutions Pilot Department Final Report EMWTP Pilot Page 25 of 25 Revision 2, date 27-April-2015 5 Discussions and Conclusions The following conclusions are drawn from the results of the study: x Stable operation was achieved with a flux rate of 45 gfd at >95% recovery. It is believed, additional capacity can be achieved with optimized pretreatment targeting a reduction of the TOC load reaching the membranes. x The Aquaflex 55 membrane consistently produced excellent water quality with an average filtrate turbidity <0.02 NTU (Figure 3). x The Aquaflex 55 membrane consistently produced safe drinking water by consistently providing an LRV greater than 4.20 100% of the time with a high of 4.89. The average LRV for the whole study was 4.53 (Table 2). x CEBs were extremely effective and consistently restored permeability to high levels (Figure 1 and 7). x The 200 ppm hypo/caustic CEB at pH 12 (CEB1A) proved to be very effective and was responsible for the majority of the permeability recovery throughout the study. x The sulfuric acid CEB at a pH of 2.0 (CEB1B) proved to be beneficial as well and was responsible for an additional ~2 gfd/psi permeability recovery during the CEBs during Stages 2 and 3. x Given the permeability loss between CEBs, daily CEBs will be required for stable operation, especially during cold water operation. x CIPs were not required to maintain stable operation and are therefore not needed or recommended.

Exposure limits are also affected by temperature, pH and the presence of metals. In order not to exceed maximum exposure limits, membranes must be preserved free of any oxidising agent when the plant is stopped.

STORAGE MEMBRANE ELEMENT DATASHEET New membrane modules can be stored as supplied in the original packaging. The membrane elements contain an aqueous preservation solution of glycerine (20wt%) and sodium metabisulfite (1wt%). Membrane modules should be stored in a dry, normally ventilated place, away from sources of heat, ignition and direct sunlight. Store between 0 and 40 °C. The membrane modules should not be subjected to any freezing temperatures. Shelf life is a maximum of 6 months for unused modules in unopened packaging under correct storage conditions after transfer of ownership for X-Flow B.V. to the Client. After the maximum period of 6 months all warrantees are null and void unless otherwise agreed in writing between the parties. After use, the UF membrane modules need to be stored wet at all times.To avoid biological growth during shutdowns or storage, wet membranes could be treated with a compatible biocide. The membrane is compatible with many common disinfecting agents or biocidal preservatives. Typically for short-term shutdowns (1 – 7 days), a daily backwash with UF permeate quality water for 30 seconds at 250 lmh, should be adequate for bacteria control. Before start of the shutdown period, the modules must be cleaned by a standard Chemical Enhanced Backwash (CEB). X-FLOW AQUAFLEX 55 ULTRAFILTRATION MEMBRANE In case of long-term storage (> 7 days), membranes should be disinfected. The membranes should be cleaned using a CEB before the disinfection step is carried out. For disinfection, a 0,5% sodium metabisulfite solution can be used. In both short and long term storage situations, the modules should remain filled with storage solution $SSHQGL[% 75540 Note: Additions shall not be made to this document without prior evaluation and acceptance by NSF International.

In order to establish this log removal a number of laboratory tests have been performed and data from full scale plants have been used. Basis of this document is the “guidance manual for membrane filtration”1 and “Aspects of Hollow Fiber Membrane Integrity testing for Regulatory Compliance”2. References to both documents can be found in the document reference list in the front. It is Norit’s philosophy to use worst case assumptions, when making calculations. This should be taken into account when comparing the results of the calculations herein with actual results from field tests. The document e.g. calculates the number of broken fibers that generate a certain log removal (see chapter 10). This calculation is based on fibers breaking near the potting. If a fiber is broken exactly in the middle of the membrane module, the effect on the log removal is approximately 30 to 40% when compared to the effect of a fiber defect near the potting. $SSHQGL[( X-Flow B.V. Technical Bulletin Know-How Centre LT2ESWTR - LRV calculation through direct integrity testing TBU-GEN-INT-02-0633 (replaces TBU-GEN-INT-02-0516)Page 5 of 19 2 Theoretical background The LRV is defined as being the following relation: )*log( breach P DIT QVCF QLRV= Equation 1: Log removal value Where: LRVDIT Log removal Value (Direct Integrity Testing) QP Filtrate flow from membrane unit to be tested Qbreach Flow of water through a breach of integrity VCF Volumetric concentration factor, for NORIT systems VCF = 1 (see document reference 3) For the calculations, it is assumed that a defect occurs as a fully cut membrane fiber. Apart from fully cut fibers, the occurrence of fiber failure can also be associated with a pinhole or small crack. A fully cut fiber however simulates the worst case situation. The flow of water through a defect consists of the sum of two streams, these streams being the individual streams through each section of fiber, as graphically represented below. Figure 2.1: flow through broken fibers Two cases have been displayed: the first one shows a fiber cut right after the epoxy potting (50 mm from the entrance of the membrane module), the second one shows a fiber cut in the middle of a fiber. 0,05 m 1,45 m 0,75 m 0,75 m $SSHQGL[( X-Flow B.V. Technical Bulletin Know-How Centre LT2ESWTR - LRV calculation through direct integrity testing TBU-GEN-INT-02-0633 (replaces TBU-GEN-INT-02-0516)Page 6 of 19 The arrows give a graphical representation of the water flows through the defect. Because of the shorter path length, the flow through a fiber section of 50 mm is higher than through a fiber section of 750 mm., assuming identical fiber failures. Similarly the flow through a fiber section of 750 mm is higher than the flow through a fiber section of 1450 mm. The total defect flow is the sum of the flows through both sections of cut fiber. This document will detail two cases: the first one being the case with a fiber cut near the potting, the second one with a fiber cut in the middle of a fiber. The water flow through the defect can not be measured directly on a full scale UF system. It is however possible to measure the air flow through a defect fiber. An empirical relation can be established between the water flow and the air flow: breachdefectairQALCRQ*=− Equation 2: flow through defective fiber Where: Qair-defect Airflow through a defect Qbreach Waterflow through a defect ALCR Air to Liquid Conversion Factor, as described in 1 $SSHQGL[( X-Flow B.V.

Each time five fibers have been tested simultaneously. Multiple fibers have been tested in order to increase the accuracy of the laboratory testing. These fibers were pressurized with air and with water in two experiments. The air flow leaving the fibers was measured by collecting the air in an upside down calibrated cylindrical container in a large container of water. The water flow leaving the fibers was monitored by collecting the water in a calibrated cylindrical container). In order to translate the results into an ALCR the following should be noted: 1. Pressures applied during water flow (filtration) and during air flow testing will differ from each other during operation of a plant. Pressure during water flow is equivalent to the actual trans membrane pressure during filtration. Pressure during air flow is the test pressure during the airflow testing. 2. The relationship between airflow and water flow will depend on the actual position of the fiber cut. 3. Only the air flow through the leak has been measured during the laboratory experiments. The diffusive airflow through the intact membrane pores has not been measured, since this depends on the actual measurement setup. Airflow test pressure to be used has to be:2 1. Less than 80% of the bubble point pressure. The bubble point pressure of the XIGA UF membrane (0.025 μm pore size) is approximately 2,000 kPa = 20 bar. 2. Below the maximum differential pressure of the membrane. The maximum recommended differential pressure during filtration of the membrane is 2.5 bar. 3. Above the pressure required for detecting a defect of a given size. As stipulated by LT2ESWTR the minimum defect size to be identified is 3 μm. This corresponds to a bubble point pressure of 84.5 kPa = 0.845 bar. See document reference 3. From above conditions it can be seen that air test pressure to be applied can vary between 0.845 bar and 2.5 bar. NORIT recommends to perform airflow testing at 1.0 bar. 1,0 bar air test pressure will be considered in what is to follow. The airflow through a fiber of 5 cm length and a fiber of 145 cm length constitute the total airflow through a fiber that is cut at the potting. The total airflow was 468 l/h @ 1 bar of air pressure. By comparison, the airflow through a fiber with a cut in the middle, i.e. two parts of 75 cm each, is only 254 l/h. $SSHQGL[( X-Flow B.V.

The worst case situation, a fiber cut near the potting, will be considered in the next paragraphs. $SSHQGL[( X-Flow B.V.

The diffusive airflow depends on the actual set up of the membrane units and the airflow testing equipment, is therefore site specific. NORIT does have access to several full scale plants that utilize airflow testing as integrity test. The typical diffusive airflow for intact membranes is in the order of 1 – 2.5 liter per element per hour, when tested at 1 bar. For the example as calculated in this document, a value of 2 liters per hour per element will be used. This equates to a background diffusive flow of 160 l/hr (half skid) or 320 l/hr (full skid). After installation of the membranes an initial reading will be taken of the diffusive airflow on each skid. This initial diffusive airflow will be applied to the LRV calculations of each UF skid. $SSHQGL[( X-Flow B.V.

Multiple control limits can be set at different levels to indicate the severity of the problem. The LT2ESWTR-mandated control limit is referred to as the upper control limit. This control limit is tied into the awarded log removal credit (LRC). The awarded LRC value for X-Flow XIGA S225 UFC M5 0.8 mm membranes is 4. An additional alert control limit can be set at e.g. a log removal value of 4.3. This can be used as an alert value.

At a trans membrane pressure of 0.3 bar (during filtration), the upper control limit for the monitored airflow is 3100 l/hr and the alert control limit is 1650 l/hr. This equates to 6 broken fibers (UCL) or 3 broken fibres (CL-alert). At increasing trans membrane pressure this value decreases to 1500 l/hr (UCL) and 830 l/hr (CL- alert) for a trans membrane pressure of 0.9 bar (during filtration). This equates to almost 3 broken fibres (UCL) and 1.4 broken fibres (CL-alert). $SSHQGL[( X-Flow B.V.

The number of allowable broken fibres per full UF rack will be double the amount of allowable broken fibres per half rack. If the flux deviates from the design flux (e.g. during periods of reduced output), this influences the control limits as well. The below graphs demonstrate the effect of varying trans membrane pressure and varying flow on the airflow rate to achieve various control limits. The LRV value is varied between 3.5 and 5 log in 0.5 log increments.

Essentially all of the organic matter will be oxidized $SU 3DJHRI Concentrate - the portion of the fluid being processed which has not passed through the membrane. This stream therefore has a higher concentration of species that do not readily pass through a semi-permeable membrane. Also known as the reject stream, or retentate Dead End Filtration – term commonly used to describe the deposition mode hydraulic configuration of membrane filtration systems; also synonymous with “direct filtration” Deposition Mode – a hydraulic configuration of membrane filtration systems in which contaminants removed from the feed water accumulate at the membrane surface (and in microfiltration (MF) / ultrafiltration (UF) systems, are subsequently removed via backwashing) Direct Integrity Test – (as defined under the LT2ESWTR) a physical test applied to a membrane unit in order to identify and/or isolate integrity breaches Feedwater – the influent stream to a water treatment process Filtrate – the water produced from a filtration process; typically used to describe the water produced by porous membranes such those used in microfiltration (MF) and ultrafiltration (UF) processes Flux – the throughput of a pressure-driven membrane filtration system expressed as flow per unit of membrane area (e.g., gallons per square foot per day (GFD) or liters per hour per square meter (Lmh)) Foulant – any substance that causes fouling Fouling – the gradual accumulation of contaminants on a membrane surface or within a porous membrane structure that inhibits the passage of water, thus decreasing productivity Hollow-Fiber Module – a configuration in which hollow-fiber membranes are bundled longitudinally and either encased in a pressure vessel or submerged in a basin; typically associated with ultrafiltration Indirect Integrity Monitoring – (as defined under the LT2ESWTR) monitoring some aspect of filtrate water quality that is indicative of the removal of particulate matter Integrity Breach – one or more leaks in a membrane filtration system that could result in the contamination of the filtrate with unfiltered feed water Log Removal Value (LRV) – filtration removal efficiency for a target organism, particulate, or surrogate expressed as log10 (i.e., log10(feed concentration ) – log10(filtrate concentration)) $SU 3DJHRI Lumen – the center or bore of a hollow-fiber membrane Module – (as defined under the LT2ESWTR) the smallest component of a membrane unit in which a specific membrane surface area is housed in a device with a filtrate outlet structure Permeability – the ability of a membrane barrier to allow the passage or diffusion of a substance (i.e., a gas, a liquid or solute) Pore size – the size of the openings in a porous membrane expressed either as nominal (average) or the absolute (maximum), typically in terms of microns Recovery – the volumetric percent of feed water that is converted to product over the course of a complete operating cycle or daily totalized flows. Recovery equals Product flow produced by the membrane unit divided by Feed flow to the membrane unit multiplied by 100%. Transmembrane Pressure (TMP) – the difference in pressure from the feed to the filtrate across a membrane barrier Turbidity – a measure of the extent to which the intensity of light passing through water is reduced by the suspended matter. Ultrafiltration (UF) – a pressure-driven membrane filtration process that typically employs hollow-fiber membranes with a pore size range of approximately 0.01 – 0.05 Ǎm (nominally 0.01 Ǎm) $SU 3DJHRI 1Introduction Toray Membrane USA contacted Alan Plummer Associates in May of 2013 after learning about this new opportunity to participate at the Fort Worth Eagle Mountain Membrane Piloting Study. Toray was invited to submit information on our pressurized HFU-2020N TIPS Ultrafiltration (UF) membrane product. Upon review of that submittal Toray was invited to participate in the study. WesTech Engineering offered to jointly participate with Toray in this study and provide their ALTAPACTM APIII Ultrafiltration pilot system. This document summarizes the findings of the pilot study program. $SU 3DJHRI 2UF Feedwater Quality The raw water source is Eagle Mountain Lake in Fort Worth, Texas. The raw water is further treated with ammonia, ozone (3-4 mg/L as O3), coagulant, flocculation, sedimentation basins and Biologically Activated Filters (BAF’s). The coagulant used in Stage 1 of this study was ferric sulfate, at a dosage of 26 to 37 mg/L. In the following Stages polyaluminum chloride was used at a dosage typically in the range of 5-10 mg/L Al3+ as coagulant.

In conventional usage, it usually refers to the separation of solid, insoluble particles from liquid or gaseous streams. Membrane filtration extends this application further to include the separation of dissolved solids in liquid streams and hence, membrane processes in water treatment are commonly used to remove various materials ranging from salts to microorganisms. The most commonly employed membrane processes and the filtration ranges in which they operate, are presented in the chart below. Membrane processes can be categorized in various, related methods, three of which are: pore size, molecular weight cutoff and operating pressure. As the pore size gets smaller or the molecular weight cutoff decreases, the pressure applied to the membrane for separation of water from other material generally increases. The water treatment objectives will determine the basis on which a process is selected. 7ULKDORPHWKDQHV 0HPEUDQH7DUJHWRI6HSDUDWLRQ䃛 P䃛 P䃛 P䃛 P6L]H 1D &O ,RQV 3HVWLFLGH2UJDQLF0DWHULDO 9LUXV %DFWHULD &U\SWRVSRULGLXP &ROLIRUP &D0J62 ,RQV 1) 1DQR)LOWUDWLRQ 52 5HYHUVH2VPRVLV 8) 8OWUD)LOWUDWLRQ 0) 0LFUR)LOWUDWLRQ ,RQVPDOOPROHFXOH 3RO\PHU &ROORLG 6LOW 7ULKDORPHWKDQHV 0HPEUDQH7DUJHWRI6HSDUDWLRQPLFURQ PLFURQ PLFURQ 6L]H 1D &O ,RQV 3HVWLFLGH2UJDQLF0DWHULDO 9LUXV %DFWHULD &U\SWRVSRULGLXP &ROLIRUP &D0J62 ,RQV 1) 1DQR)LOWUDWLRQ 52 5HYHUVH2VPRVLV 8) 8OWUD)LOWUDWLRQ 0) 0LFUR)LOWUDWLRQ PLFURQ PLFURQ $SU 3DJH RI 4.2 Toray Ultrafiltration Water Treatment Process General Overview Feed water is pumped to the membrane modules at a maximum feed pressure of 43.5 psi. Particulate matter, including Virus, Giardia cysts and Cryptosporidium oocysts, remain on the outside of the membrane fiber while permeate enters through to the inside of the hollow fibers and exits the top port of the membrane module. The filtration cycle continues for approximately 30 minutes, depending on recovery and flux, and then the particulate / suspended solids are removed from the module during the backwash cycle. In the backwash cycle, feed to the module stops and filtrate from the backwash tank is directed into the hollow fibers from the top port for 30 seconds. The top-side port is open allowing the excess water to overflow to drain. Next air bubbles scour the membranes for 30 seconds and then the module is gravity drained from the bottom port. The overall backwash cycle requires approximately 3.25 minutes. Since the membrane modules are preserved in 1.32 gallons (5 L) of 100 mg/L sodium hypochlorite solution, rinsing of the membranes is not required. In fact, no pre- conditioning steps were taken prior to the commencement of this pilot study. Toray Maintenance Cleans (TMC) were performed once every 3 days in this pilot study. TMCs were initiated after the backwash cycle and involved soaking the membranes in a 300 mg/L chlorine solution for approximately 20 minutes. The overall TMC cycle required approximately 23 minutes. CIP Cleaning is normally performed when the TransMembrane Pressure (TMP) approaches the maximum of 29 psi. CIP cleaning is similar to a TMC except the cleaning solution is recirculated for 3-4 hours, normally at elevated temperatures. Also the chlorine or citric acid concentration is higher than the concentrations used during a TMC. For this pilot study a CIP clean was performed twice as per the TCEQ protocol. The TMP remained less than half the maximum operating pressure of 29 psi throughout the study. Membrane Integrity Tests (MITs) were performed daily by pressurizing the module with compressed air on the feed side of the fiber at a pressure of 20 psi. Once the water has been purged from the system the pressure in the module is monitored and recorded to evaluate the membrane integrity. At the end of the test the air is purged and the system returns to normal operation. The test lasts approximately 7 minutes. $SU 3DJHRI 5Results 5.1 Operational & Laboratory Results The WesTech / Toray Ultrafiltration pilot unit began operations October 23, 2014, twelve days before the official start date of November 4th, 2014. Feedwater to the pilot unit came from the Eagle Mountain Lake which had been pretreated with ammonia, ozone, coagulant, flocculation, sedimentation basins and BAF’s. The WesTech ALTAPAC APIII UF pilot unit with the Toray HFU-2020N module successfully treated the feedwater at 60 - 90 gfd Temperature Corrected (TC) flux with a TMP of 6 – 14 psi, less than half of the maximum operating TMP of 29 psi. The system recovery ranged from 97.4 to 97.6 % based on daily totalized flows. Figure 1 below shows an overview of the instantaneous flux, normalized flux (temperature corrected to 20 deg C), specific flux and feedwater temperature throughout the 4-month pilot study program. The data was filtered to only show data that corresponded to production data, by setting 50 gfd < Instantaneous Flux < 60 gfd and 5 psi < TMP < 15 psi. $SU 3DJHRI Figure 2 shows the daily averages for flux, temperature corrected flux and feedwater temperature for each stage of the pilot study program. Instantaneous temperature corrected flux rates peaked at 90 gfd as shown in Figure 1. As previously mentioned, the TMP ranged from 6 – 14 psi, less than half of the maximum operating TMP of 29 psi, throughout the 4-month pilot study program. Figure 3 on the following page shows the TMP values at an instantaneous flux rate of 57 and 60 gfd. All values are logged at 4-hour intervals. The data was filtered to only show data that corresponded to production data, by setting 50 gfd < Instantaneous Flux < 60 gfd and 5 psi < TMP < 15 psi. $SU 3DJHRI Further details are shown in Figure 4 below, which also includes temperature and temperature corrected TMP. The data was filtered to only show data that corresponded to production data, by setting 50 gfd < Instantaneous Flux < 60 gfd and 5 psi < TMP < 15 psi. $SU 3DJHRI Details for each stage of pilot testing are described in Appendix 6 and in the following sections. In each of the Stage Summary Tables, the data was filtered to only show data that corresponded to production data, by setting 50 gfd < Instantaneous Flux < 60 gfd and 5 psi < TMP < 15 psi. 5.1.1 Stage 1 – Optimization (Ferric Sulfate) Based on the June 20, 2014 Pilot Testing Protocol, Stage 1 used ferric sulfate as the coagulant in the pretreatment. Stage 2 and 3 involved further testing with ferric sulfate. The City of Fort Worth decided to focus on testing with polyaluminum chloride (PACl) and subsequently cancelled Stage 2 and 3. For six weeks from October 23 to December 4th the pilot unit operated at an instantaneous flux rate of 57 gfd and 97.6% recovery. From December 4th to 9th an error resulted in the flow being reduced from 30.7 to 29 gpm which reduced the instantaneous flux rate from 57 gfd down to 54 gfd. $SU 3DJHRI During this stage the following was observed: oFeedwater temperature from 18 deg C down to 6.7 oC oOperating TMP from 6 - 12 psi oFeed Turbidity typically less than 0.3 NTU, with 2 peaks less than 2 NTU oPermeate (Filtrate) Turbidity typically 10 to 20 mNTU (0.01 to 0.02 NTU) with 2 peaks less than 0.09 NTU. All values were less than 0.1 NTU. Table2:SummaryStage1 A CIP was performed at the end of Stage 1; further details are in section 5.2.2. As previously mentioned Stage 2 and 3 with ferric sulfate coagulant were cancelled. 5.1.2 Stage 4 – Optimization (PACl) The official start date for Stage 4 was December 15th, 2015. Since the first CIP was performed on December 9th and 10th the WesTech / Toray pilot unit began Stage 4 operations on December 10th and ended January 8th for a total of 4 weeks. The coagulant was switched from ferric sulfate to PACl. The dosage ranged from 5 to 15 mg/L as Al3+ as coagulant. As part of this optimizing phase the flowrate to the WesTech / Toray pilot unit was increased to 32.3 gpm which equals an instantaneous flux rate of 60 gfd (32.3 gpm x 1440 / 775 ft2). The recovery was maintained at 97.6%. From the graphs at the end of this report the following was observed: oFeed temperature from 8 - 14 oC oOperating TMP 8 – 14 psi oFeed Turbidity typically < 0.2 NTU, all values below 0.4 NTU oPermeate (Filtrate) Turbidity equal to 0.01 NTU (10 mNTU), with a peak up to 0.05 NTU, $SU 3DJHRI Table3:SummaryStage4 During Stage 4 the temperature corrected flux rose from 70 gfd up to 81 gfd, due to the colder feedwater temperatures. It was anticipated the feedwater temperatures would drop even further in January and February during Stage 5 of the pilot testing. Based on the anticipated lower feedwater temperatures it was decided to continue at an instantaneous flux rate of 60 gfd. For drinking water systems, the HFU-2020N UF module is certified to operate at a maximum temperature corrected flux rate of 100 gfd. 5.1.3 Stage 5 – Verification (PACl) Stage 5 began January 8th and finished February 11th (5 weeks). As required by the pilot protocol the optimal flux and recovery rate from Stage 4 were kept during Stage 5. The pilot unit operated at an instantaneous flux rate of 60 gfd and 97.6% recovery. Observations from this Stage are noted below and further details are in Table 4 on the following page: oFeed temperature from 6 - 11 oC oOperating TMP 10 – 14 psi oFeed Turbidity 0.06 to 0.6 NTU oPermeate (Filtrate) Turbidity from 0.013 to 0.009 NTU (13 - 9 mNTU) Table4:SummaryStage5 $SU 3DJHRI 5.1.4 Stage 6 – Irreversible Fouling Assessment (PACl) Stage 6 began February 12 after CIP #2 was performed and lasted until February 23rd. The goal of this stage is to determine the percentage of irreversible specific flux loss from the beginning of this study until the end. During this Stage the pilot unit operated at the same design conditions as in Stage5, instantaneous flux rate of 60 gfd and 97.6% recovery. Results from this stage are noted below: oFeed temperature from 9 - 12 oC oOperating TMP 7 – 11 psi oFeed Turbidity 0.08 to 0.4 NTU oPermeate (Filtrate) Turbidity equal to 0.009 NTU (9 mNTU), with a peak up to 0.04 NTU, Table5:SummaryStage6 As you can see from Figure 5, on the following page, the daily average specific flux remained stable in the range of 6-8 gfd/psi. Figure 6 shows the percent loss of specific flux as compared to the specific flux achieved after the first CIP. These results show the membranes did not experience any irreversible fouling over the 4-month period of operations. The data was filtered to only show data that corresponded to production data, by setting 50 gfd < Instantaneous Flux < 60 gfd and 5 psi < TMP < 15 psi. The 2 CIP’s performed resulted in temporary specific flux rates of 10.5 gfd/psi. After operations they stabilized at 6-8 gfd/psi range. $SU 3DJHRI $SU 3DJHRI 5.2 Cleaning Results 5.2.1 Toray Maintenance Cleans Toray Maintenance Cleans were performed once every three days using a 300 mg/L unheated sodium hypochlorite solution. 5.2.2 Clean In Place (CIP) Cleans Two CIP’s were performed on the pilot unit. The first one on December 9 th and 10th, 2014 and the second one on February 11, 2015. For CIP #1, the first part of the clean circulated a 3,000 mg/L sodium hypochlorite solution for a 3 hour period at a temperature of 36 deg C through the membrane. The second part of the clean circulated a 5,000 mg/L citric acid solution for a 3 hour period at a temperature of 36 deg C through the membrane. The Temperature Corrected Permeability (TCP) increased from 6.3 gfd/psi up to 10.2 gfd/psi after the sodium hypochlorite clean. The permeability further increased from 10.2 gfd/psi up to 10.5 gfd/psi after the citric acid clean. The majority of the foulants were organic and removed by the sodium hypochlorite. The overall result of this first CIP was an increase in the temperature corrected permeability from 6.3 gfd/psi up to 10.5 gfd/psi. For CIP #2, very similar results were observed. The 3,000 mg/L sodium hypochlorite solution was recirculated at 34 deg C for a 3 hour period. The temperature corrected permeability increased from 6.6 gfd/psi up to 10.0 gfd/psi. After the pilot unit was flushed with clean water a 5,000 mg/L citric acid solution was recirculated through the membranes for 3.5 hours at 34 deg C. The temperature corrected permeability increased from 10.0 gfd/psi up to 10.5 gfd/psi. For CIP #1 the pH values of the cleaning chemical solution was recorded. For the second CIP the pH values were not recorded. Toray only targets a pH value for CIP cleans where metals fouling is suspected, such as iron, aluminum and manganese. For normal CIP cleans Toray only targets the chemical dosage and not the pH. Please see Figure 7, below and Appendix 7 for further details. $SU 3DJH RI 5.3 Integrity Test Results 5.3.1 Indirect Integrity Monitoring Indirect integrity monitoring was performed using an on-line turbidimeter. Filtrate turbidity throughout the 4-months of operation was excellent ranging from 9 to 13 mNTU (0.009 – 0.013 NTU). Feedwater was measured at 15 minute intervals and filtrate water was measured at 5 minute intervals. Please see Figure 8 below for further details. $SU 3DJHRI 5.3.2Direct Integrity Monitoring Direct integrity monitoring for this pilot study was based on a Pressure Decay Test (PDT). This test was conducted by draining the feed side of the module and then pressurizing the feed side of the module with clean, dry, oil-free air. After which, the air pressure was recorded (PDT Initial) and held for five (5) minutes. At the end of the five minute period the air pressure was recorded again (PDT Final). The PDT test results are based on Toray’s Log Removal Value (LRV) Calculator tool. The LRV calculations are based on the EPA’s Membrane Filtration Guidance Manual published in November 2005. In this manual two different flow models can be used, either the Hagen-Poiseuille (laminar breach) or the Darcy Pipe (turbulent breach). Since the results from the Darcy Pipe calculation are more conservative it was decided to use those calculations. On the following page are the parameters used in the LRV calculations: $SU 3DJHRI Table6:LRVParameters Description Pore shaped correction factor (K) 1 Surface tension of water at 5 oC (ǔ) 75.6 dynes/cm Liquid membrane contact angle (lj) 0 degrees (most conservative) Maximum anticipated backpressure (BPmax) 3.62 psi Minimum starting pressure for PDT (Ptest min) 18.2 psi Maximum water temperature, for sensitivity calculations (Tmax) 68 oF Maximum allowable TMP, for sensitivity calculations (TMPmax) 29 psi Water temperature for actual LRV calculations (Tactual) 50 oF Average TMP for actual LRV calculations (TMPactual) 10 psi Pressure transmitter accuracy (delta Ptest) 0.021 psi/min Flow Regime for ALCR calculation Darcy-Pipe (most conservative) Baseline (diffusive) decay (ƦPDiff) 0 psi/min (most conservative) Volumetric Concentration Factor (VCF) 1 Pressure Decay Test (PDT) Duration 5 minutes Volume of pressurized module and piping during test (vsys) 10.28 gallons Due to technical difficulties the PDT results from the PLC were not recorded until February 3rd, 2015. Fortunately the plant operators were logging the PDT loss results periodically through November 4th and February 3rd, and those values are noted below. The maximum LRV seen between February 3rd and February 23rd was 4.8499.

Proving the membrane was intact throughout the course of the pilot study. $SU 3DJHRI 6System Downtimes As with all pilot studies mechanical or electrical issues as well as power outages can result in periodic down times. The WesTech / Toray pilot unit experienced only a small number of down times when compared to the overall run time of the pilot unit. Operations began officially October 4, 2014 and ended February 23, 2015 for a total of 143 days. Please see Table 8 below for details on the downtimes and the reasons for the downtimes.

The filtrate turbidity readings were all less than 0.1 NTU 100 percent of the time and on average equal to 0.011 NTU. 2.CIP cleans were performed between two stages, but were technically not required during the 4 month period. The maximum TMP was 14 psi, which is less than half of the available operating TMP of 29 psi. CIP cleaning interval is estimated to be between 4-6 months. 3.As shown in Figure 6 there was a zero percent decrease in specific flux following each CIP. 4.Each daily direct integrity test (DIT) and DIT’s following CIPs passed. Conservative parameters were used in the LRV calculations including Darcy Pipe flow model, 0 degrees contact angle and 0 psi/min diffusive decay. 5.Zero fiber breaks occurred during the entire pilot study, including start-up. 6.CEB frequency (Toray maintenance cleans) were performed once every 3 days and helped to sustain a high flux and recovery rate. 7.Membrane instantaneous flux of 60 gfd and 97.6% recovery were sustainable. The WesTech / Toray pilot unit successfully treated clarified feedwater at temperature corrected flux rates of 60 - 90 gfd. 8Recommendations for Full-Scale System Based on the results from the pilot study, the following guidelines are recommended for the full-scale system: Table9:FullͲScalePlantRecommendations ParameterRecommendation Module type HFU-2020N Membrane instantaneous flux 60 gfd. Overall system recovery 97.6% Air flow / per module 3.53 scfm / module $SU 3DJHRI ParameterRecommendation Backwash frequency 30 sec. for every 30 minutes of filtration (filtration duration may be adjusted slightly to meet the 97.6% recovery on full-scale plant) Minimum Feed temperature 6.0 deg C Cleaning Chemicals Sodium Hypochlorite (12%) and Citric Acid (50%) Cleaning Frequency Sodium hypochlorite CIP when TMP approaches maximum of 29 psi. Since there was no observable fouling, a CIP using both sodium hypochlorite and citric acid is recommended once every 4-6 months. One maintenance with 300 mg/L sodium hypochlorite clean every three days.

Membrane Information Worksheets Appendix E contains the membrane information worksheets for the BASF, Dow, Pentair, and Toray membranes. The following general notes and assumptions apply to each worksheet: o Stage 5 system set points are used to complete the worksheets. o Fifteen seconds are added to the vendor reported backwash and CEB interval times to account for transitions and valve actuations. o Backwash and CEB waste volumes are calculated from the Stage 5 target flow rates and durations. o CIP durations are based on the CIPs conducted after Stage 5. o CIP frequencies are based on vendor recommendations. o A CIP waste volume of 30 gallons per module per CIP chemical is assumed for CIP events. o A full-scale DIT interval of once per week is assumed for the worksheet calculations. (The pilot units conducted DITs at a conservative interval of once per day.) o A DIT duration of 10 minutes is assumed for each DIT. o The calculations to determine the minimum number of modules do not consider factors such as redundancy and system downtime.

Gupta, Gupta & Associates, Inc. 1 INTRODUCTION The City of Fort Worth (City) is conducting a membrane filtration pilot study at the Eagle Mountain Water Treatment Plant (EMWTP) to evaluate up to four suppliers (Vendors) of positive pressure-driven, hollow- fiber microfiltration (MF) or ultrafiltration (UF) membranes. In Texas, membrane filtration is considered to be an innovative technology, and the Texas Commission on Environmental Quality (TCEQ) requires that a licensed engineer provide either pilot test data or data collected at a similar full-scale facility to demonstrate that the innovative treatment system meets drinking water standards. The purpose of the pilot test is to demonstrate the treatability of Eagle Mountain Lake as a surface water source, verify compliance with drinking water standards per TCEQ requirements, and establish design criteria for a planned future expansion of the EMWTP to add an MF or UF system with up to 35 million gallons per day (MGD) of net filtration capacity (possibly in phases). The pilot study results may also be used by the City for membrane replacement projects at its other water treatment facilities if approval is granted by the TCEQ. Alan Plummer Associates, Inc. (APAI, Engineer) has been retained by the City to conduct the pilot study. APAI has assembled a project team that includes CDM Smith, Inc. (CDM), Gupta and Associates, Inc. (GAI), and Separation Processes, Inc. (SPI). The pilot testing responsibilities of the City, its Engineer, and the selected Vendors are defined within this pilot testing protocol. Vendors are required to successfully complete the pilot test and satisfy the requirements herein in order to be considered for the future membrane design and construction projects . Pilot testing is scheduled to begin in August 2014 with an anticipated testing duration of five (5) to six (6) months.

If a Vendor is unable to start a test stage at the appointed start date, the Vendor may be considered unsuccessful and disqualified from further testing at the discretion of the City and Engineer. TECHNICAL MEMORANDUM Eagle Mountain Water Treatment Plant Membrane Pilot Study Pilot Testing Protocol for Membrane Filtration 10 of 20 f:\projects\0318\054-01\doc\techmemo\final\pilot study protocol\eagle mountain water treatment plant pilot study protocol.docx Stage 1 – Optimization (Ferric Sulfate) Stage 1 establishes site-specific operating parameters for each membrane pilot system. This stage is used to select a set of optimized operating conditions to be used in Stages 2 and 3. The operating parameters shall be documented and include, but not be limited to, the following: 1. Pretreatment requirements; 2. Flux; 3. Backwash frequency, duration, flux rate; 4. CEB frequency, duration, flux rate, soak time; 5. CIP procedure; 6. Recovery. Stage 1 will last approximately 30 days. The pilot systems will start up at typical flux rates, and then slowly increase the flux rates to the Vendor determined optimum values. The goals of Stage 1 testing include maximizing flux and recovery while minimizing CEB/CIP frequency. If the TMP escalates to an unacceptable threshold per predetermined Vendor guidelines, the pilot system will undergo a CIP followed by a DIT, and the flux rate will be reduced. An account of each CIP (for all stages) should be documented in the Vendor’s pilot study report. If Stage 1 testing reveals site-specific conditions that require modifications to the pilot study protocol, the pilot study protocol may be changed by the City and Engineer. Vendors will be notified of pilot study protocol changes in a timely manner. A CIP may be conducted at the end of Stage 1 at the discretion of the Vendor. Stage 2 – Verification (Ferric Sulfate) Stage 2 tests each membrane module using the optimized set of operating parameters determined during Stage 1. The pilot system must operate for a minimum of 30 days using the selected set of operating parameters and procedures without adjustment and without the need to conduct a CIP. Stage 2 will conclude with a CIP followed by a DIT. Stage 2 results are used to determine the total time a membrane system is in filtrate production, backwash, and CEB modes as well as any other production limiting modes during the 30 day test period. Operating procedures that result in time out-of-production must be taken into account when calculating the TCEQ’s approved net capacity. For any unscheduled downtime greater than 24 hours, the Vendor must notify the City and Engineer prior to restarting the pilot system . If the specific flux or TMP of a membrane pilot system reaches unacceptable levels before the end of the 30 -day test period, the Vendor may be eliminated from further consideration and testing at the discretion of the City and Engineer. Stage 3 – Irreversible Fouling Assessment (Ferric Sulfate) Stage 3 of testing establishes the percent loss of the original specific flux for each membrane module and determines if irreversible fouling has occurred. Stage 3 involves operating the membrane modules at the simulated full-scale operating conditions from Stage 2 for at least 14 days. Stage 4 – Optimization (PACl) Stage 4 establishes site-specific operating parameters for each membrane pilot system. This stage is used to select a set of optimized operating conditions to be used in Stages 5 and 6. The operating parameters shall be documented and include, but not be limited to, the following: TECHNICAL MEMORANDUM Eagle Mountain Water Treatment Plant Membrane Pilot Study Pilot Testing Protocol for Membrane Filtration 11 of 20 f:\projects\0318\054-01\doc\techmemo\final\pilot study protocol\eagle mountain water treatment plant pilot study protocol.docx 1. Pretreatment requirements; 2. Flux; 3. Backwash frequency, duration, flux rate; 4. CEB frequency, duration, flux rate, soak time; 5. CIP procedure; 6. Recovery. Stage 4 will last approximately 14 days. The pilot systems will start up at typical flux rates, and then increase the flux rates to the Vendor determined optimum values. The goals of Stage 4 testing include maximizing flux and recovery while minimizing CEB/CIP frequency. If the TMP escalates to an unacceptable threshold per predetermined Vendor guidelines, the pilot system will undergo a CIP followed by a DIT, and the flux rate will be reduced. An account of each CIP (for all stages) should be documented in the Vendor’s pilot study report. If Stage 4 testing reveals site-specific conditions that require modifications to the pilot study protocol, the pilot study protocol may be changed by the City and Engineer. Vendors will be notified of pilot study protocol changes in a timely manner. A CIP may be conducted at the end of Stage 4 at the discretion of the Vendor. Stage 5 – Verification (PACl) Stage 5 tests each membrane module using the optimized set of operating parameters determined during Stage 4. The pilot system must operate for a minimum of 30 days using the selected set of operating parameters and procedures without adjustment and without the need to conduct a CIP. Stage 5 will conclude with a CIP followed by a DIT. Stage 5 results are used to determine the total time a membrane system is in filtrate production, backwash, and CEB modes as well as any other production limiting modes during the 30 day test period. Operating procedures that result in time out-of-production must be taken into account when calculating the TCEQ’s approved net capacity. For any unscheduled downtime greater than 24 hours, the Vendor must notify the City and Engineer prior to restarting the pilot system. Stage 6 – Irreversible Fouling Assessment (PACl) Stage 6 of testing establishes the percent loss of the original specific flux for each membrane module and determines if irreversible fouling has occurred. Stage 6 involves operating the membrane modules at the simulated full-scale operating conditions from Stage 5 for at least 14 days. Stage 6 will conclude with a second CIP followed by a direct integrity test if the optional Stage 7 testing is not conducted. Stage 7 (Optional) The City and the Engineer will determine whether or not to conduct the optional seventh stage if additional data is needed after completion of the first six stages. Stage 7 testing, if conducted, is anticipated to last approximately 30 days. 9.2 Indirect Integrity Monitoring Continuous indirect integrity monitoring of the filtrate is required for each membrane system. Indirect integrity monitoring shall be accomplished with Hach FilterTrak (FT660) laser turbidimeters (or TCEQ approved equivalent).

Typically, we request that direct integrity tests be conducted during the pilot study at the same frequency as will be required for the full‐scale facility. For most surface water systems (with a Bin Classification of 1), the DIT must be conducted at least once every seven days (and anytime the filtered water turbidity exceeds 0.15 NTU on two consecutive events).

The pilot study is still ongoing, and we discovered that the pressure decay test results for one of the pilot units are not available for a portion of the study. The pilot unit is programmed to perform a pressure decay test once per day; however, the test results were not recorded regularly during the Stage 1 optimization testing (using PACl coagulant for pretreatment). We are currently operating in the Stage 2 thirty day demonstration period. Details on the available data are provided below. The PDT results that we do have are consistent in value. Stage 1 Testing (PACl coagulant): Started: 12/15/2014 Concluded: 1/5/2015 PDT results were recorded on 12/20/2014, 12/21/2014, and 12/24/2014. Stage 2 Testing (PACl coagulant): 2 Started: 1/8/2015 Daily PDT results recorded from 1/10/2015 forward. Please advise us if further action is required. Thank you, Chris Christopher C.

Water treatment plants achie�e these treatment te�hnique requirements #hrvugh a connbination of physical and c�emical harriers. T'hese treatrnen# teohniques are generaIly achie�ed at wa#er treatment plants that incorporate �oagulation, flocculativn, clarifcativn, granular media �ltrativn and disinfection. Hvwe�er, Title 30 TAC §290.42(g} of the Texas Commission on Enviranmental Quality (TC�Q} rules allows systems to utilize ir�novati�e or aiternate treatment systems to achie�e the treatmen# tec�nique requirements. When these innv�ative or alternate treatment systems are proposed, the rules require a li�ensed professional engineer to pravide piiot tes# data or data collected at sirnilar ful]-sca3e operations demonstrating that the groposed treatment systems wi�l produce water that meets the requiremez�ts of Title 30 TAC Chapter 29�, Subchapter F, Drinkin� Water Standards Ga�erninr� Water Qualitv and Repartin� Requirements fnr 1'uhlic Water Systems. Qr+e emerg-ing ai#ernati�e treatment system that is be�aming a cpst-effective treatment far many surface water and grnund water under the infiuence af su.rface water systems is membrane �ltration. Membrane filtration units can be installed in tieu of granular media fiiters at most water treatment plan#s and, in some cases, can be used in lieu of complete conventinnal treatment. Normally, these will be ❑f the hollow-fiber (HF) znicrofiltration {MF) ul�afiitratian (LIF} rypes. Hawe�er, in some cases nanofltrativn {NF} and re�erse osrriasis {Rp} membranes are used. While all faur types of inemhranes achie�e parti�ulate and micrvvrganism rema�al, NF and R� membranes can alsa remo�e undesirabie chemical constitutes and nnay be used for achie�ing �ampliance with state and federai drinking water standards. As rnembrane filtratian has be�ome economically feasihle, the TCEQ staff have been re�eiwing an increased number of proposals to pilot and install different types af inem�rane filtratian units. Purpose of this PDW Pragram Staff Guidance This PDW Pragram Staff Guidan�e is intended to facilitate consistent and timely re�iews of pilot study reports submitted on membrane f ltration units by the TCEQ staff ar�d de�elop a written respanse for each sut�rnittal stating whether the pilnt study was acceptabte or unacceptabte.

The purpose of a pilot study report is ko provide the TCEQ staff with the results and �an�lusions af the pilot study, and to facilitate acceptance of the re�ommendatfons fvr the fu11-scale water treatment plant design. When reviewing a pilot study report, the T�EQ staff must be aware of and consider #he following. I. Acceptance ofpilot study data or the propased full-scale design criteria is nvtappro�al far cvnstruction of any membrane units far treatment of water for a public water systenn. Canstru�tion ❑f the membrane water treatrnent facilities may not begin unti3 the TCEQ staff has reviewed and apprn�ed the site-specific final engineering plans and sgecificatians for modifications to an existing or a new full-s�ale water treatment plant. Il. Linless a site-specific reyuest for an exception was re�ei�ed and granted hy TC�Q staff, a pilot study must be cnnducte� and data collected far a period of at l�ast 9fl days. At least 3Q days zr3ust be conducted under the proposed fu31-s�al� pretreatment scheme and membrane fluxrate, TMP, backwash �arameters and cnemical clean-in-place [CIP) procedures. The 30-day simulated full-scale run rr►us# be fpllawed hy a CIP pracedure and at least another tens of operation under the same full-scaie aperating conditions. III. The pilot study report must he prepared by the systems's prnfessional engineer, iicensed hy the Texas Board af Professional Engineers, and a��ompanie[i by a �over letter that is signed, sealed and daied. VI. The TCEQ staff that is reviewing a pi�ot study report may request a meeting with a responsible af�cial of the publi� water system or their professivnal engineer prior to accepting the pilot study report ar t}�e proposed design criteria. V. Ea�h membrane unit tested must be of the same design a�d contain fibers of the same length and ty�e as will be spe�ified in the full-scale water treatment plant. VI. As the TCEQ's design capaciry and flow r�porting requirements are in Engiish Units, the flow raEes must be reported in gailons per minute {gpm) or millian galions per day �MGD} and flux rates in gailons per square foot per day (gfd} to facilitate the re�iew process. VII. Pilvt studies are nae�nally conducted in three stages. Hawe�er, ea�h stage may contain mare than nne phase nf testing. T�ite TCEQ requires pilot studies t� be conducted for a period of at least 9U days unless a written exception to this requirement was requested ar�d granted. A CII' procedure and direct integrity test must ha�e been conducted prior to }aeginning ea�h of these three stages of testing. A. The Stage i test perind shauld establish site-spe�iftc and full-scale pretreatment operating parameters for each tested mem�rane unit in regards to pretreatment requirernents, specific flux rate, ha�kwash frequency, hactcwash duration, backwash flow rate, and CIl' procedures. eontinued TEXAS COMMISSI4N �N E1V �IRUNM��VTAL QUALITY PDW PRDGRAM STAFF GZII�ANCE Guidance Title: REVIEW UF PILOT STLTDY REPURTS FUR MEMBRANE FILTRATIaN Rules Affected: Title 34 TAC §29�.42(g), §29Q.104, §290.105, §Z90.11�{b)(1} and §294.111{b}(2} Page 3 of 1� A selected set of optimized conditions de�elaped under the Stage I testing are used tn conduct the Sta�e 2 and 3 testing. If NF pr R� meznbranes are heing used in an integra#ed membrane system ta treat only a portion of the water, a blending ratio must �e esta�lished ta achie�e comp�iance wfth the drir�king wa#er standards. Be aware that the Stage 1 test period data may indi�ate [hat modifcations to the ac�epted pilot study protocol were reyuired far one ar aIi memhrane test units. B. After the Stage 1 test period, a chemical CIP and direct integrity test must be canducted on each memhrane test unit hefore �eginning the second stage of tesiing. The Stage 2 test period must be fvr a minimum vf 3a days under each membrane unit's selected set of fuil-scale operating conditions and �erify the �anclusions reached from data coiiected duringthe Stage i testperiod. For any unscheduled downti�ne greater than 24 hours, dacumentation must be included indicating that the TCEQ was cnntacted to see if the Stage 2 test period needed ta be restarted. AlI membranes are operated under pararne#ers that consist either of a constant flux rate with a �arying transmembrane pressure (TMP} or a constant TMP with a �arying #lux rate. When a membrane is in operation it continues to ha�e an in�rease in the fouling that the backwash/hacicflushlxe�erse flaw cycles do not remo�e. Once the varying parameter degrades to the manufactures recommended set point, a CIP procedure must be conducted to remo�e the fouling ar�d restare the operaring flux rate and TMP tn an acceptable le�e1. If the flux rate or TMP for a membrane unit reached unac�epta�ie levels before ihe end of the 3�-day test period, the engineer or system may ha�e chosen to start a membrane unit's Stage 2 test period over under different simulated full-scale operating conditians. Howe�er, they may ha�e chosen to �onduct a CIP ar�d direct integnity test and connplete the 30-day test period under the same aperating conditions. In this case, the CIP duration is iess than 30 days and the time out of service must be taken into cnnsideratian when calculating the TCEQ's approved net capacity because af the decrease ir� frequency of CIP procedures. Please note that Norit uses a chemi�al cleaning �rocess far their membranes that consists �f a series of "chemiaal enhanced backwash {CEH)" procedures using an acidic soluti4n mixed in with t�e chlorinated fltrate hackwash procedures approximately ever 18 ta 24 ba�kwashes in lieu of a single CIP procedures conducted e�er 30 days or so. T'he CEB procedures are ap�raxirnately 10 ta 15 minutes in duralion. Also, depending on the feed water quality, ather membrane �endors wil] snmetimes use similar prncedures �pndu�ted at fr�q�encies from once per day t� once per wee}c that they refer to as"enhanced filtrate maintenance," "mini CIP" or "chemica! saaks" to exten� the frequency between their normal CIP pracedures. AIl Qf these procedures result in tirne out of produ�tion for the mem�rane units and must be taken into account when calculating the TCEQ's a�proved net capacity for a specific membrane unit. Howe�er, single CIP pro�edures conducted at a irequency of 3U days, ar greater, that results in offline perinds of less than four hvurs ger mvnth, do not sigriificantly affect the average daily net prqductian. conti�ued T.EXAS C�1IIMISSI4N 4N' EIVYIRa1VME11�TAL QUALITY FD N� PRQGRAM STAFF GUIDANCE Guidanee Titie: REVIEW UF PIL�T STLTDY REPQRTS FUR MEMBRANE F�LTRATIUN Ruies Affected: Title 30 TAC §240.42(g), §290.1Q4, §29D.145, §29Q.11fl[b)(1) and §29d.111(b}(2} Page 4 of 1Q C. The Stage 3 test perivd mus# ha�e included a CIP and direct integrity test followed by aperaC�n� a minimum of ten d�ys at the simuiated full-scale operating conditians selected for the 5#age 2 testing. This is used to establish the % loss of original specific flux, temperature adjusted to 2Q° C, and determine if any irreversible membrane fouling af each membrane unit has occurred. If the % loss of original specifi� flux for a specific membrane unit ar % of irreversible membrane fouling is determined ta be excessi�e, the selected full-s�ale aperatingcnnditions may result in the TCEQ's appro�ved design �apacity bein� less than is re[�uired or desired by the system. A rapid increase in irre�ersible Fouling can result in de�adatian af net production and premature replacement of inerrcbrane units in a fuli-scale membrane installation. Under these �onditions the re�iewing TCEQ staff should include camments in the pilvt study review le�ter stating that the pilot st�.�dy indicates that the simulated full-s�ale operating conditiuns for the speci�� membrane unit indicates rapid fouling at 1he selected operating cs�nditions and the patential for rapid degradatian oF the net production and a short mem6rane jife. Alsa, the TCEQ's ac�epted net productian for ari indir�idual memhrane unit may need to he reduced.

The purpase of the pilot study is to evaluate four m�mbrane manufacturers for expaz�sion of the membrane treatment facility for up to 35-mi�lion gallons per day (MGD) capacity. Exceptions for the use of inembrane filtration must be approved in accordance with the requirements in Title �o of the Texas Administrative Code (�o TAC} §2go.42(g). We are granting your request to use membrane treatment based on the site-speci�c performance during the pilnt study for each of the four manufacturers as follows: BASF inge�� dizzer�� XL o.9 MB �o W UF Modules T��e TCEQ finds that the BASF inge� dizzer� XL o.g MB �o W UF module is accepted to yield a maximum of 202 allons er da GPD of filtrate water (at 2a� C} available for use by tl�e City af Fort Worth Eagle Mountain Water Treatznent Plant customers for a ��g square-feet (ft'-) membrane element based on the following operating parameters of the pilot testing: • A backwash cycle of once every 3o minutes For a duration of 45 secQnds; • A chemically enhanced backwash (CEB) once each day for a duration of 66 minutes (33 minutes caustic cycle and 33 minutes acid cycle}; • A total of 1,34o minutes per day in filtrate mode and ioo minutes per day in backwash mode or other maintenance activity; • For each BASF inge� dizzer��XL o.9 MB �o W UF Madule, 2,08�. gallons are used per module er da for in- lant filtrate use; P.O.

Page 2 November 30, 2015 • A filtrate flux rate of �o.� �allons �er square faot per da�(gfd) at 20� C; and, • Based on the gross filtrate production of 4g,2.83 GPD and the in-plant filtrate use of 2081 GPD, the nei �ltrate capacitv is 47,202 GPD per 753-ftz module at 20° C. Based on our understanding of the submitted pilot study data, the TCEQ wauld issue a ca aci rating of 3�� million gallons per da�(MGD� for a proposed surface water treatxnent plant (SWTP} design using 2 BASF in e� dizzero XL o. MB o W UF Modules. The TCEQ issues a net ca�acity rating for HF membrane facilities based on an instantaneous filtrate flux corrected to 20° C. This rating is detErmined by subtracting the total in-plant use of fiitrate {for backwashes, maintenance cleaning, and other in-plant use) from the gross potential filtrate production of a membrane unit. The TCEQ understands and accepts tha� an increase in zirzembrane feed water tempera�ure normally results in an increase in the filtrate flux rate and a corresponding increa�e in patable water available for custom.er use. A decrease in water temperature will resul� in a reduction of the filtrate flux rate and a corresponding decrease in potable water available for customer use. This seasonal increase and decrease of water temperatur� corresponds to the accepted increase of summ.er and decrease of winter customer demands. This increased production shall have TCEQ approval provided it does nat exceed a temperature-corrected filtrate flux rate based on tlae following calculation from the United States Environmental Protection Agency (USEPA) Mernbrane Filtration Guidanc� Manual: E�uation 2.10: Jao = J�r � [1.784 — (0.0575 � T) + (O.Q011 x TZ) — (ia-5 x T�i) Where: J2o is the normalized flux at 2o°C (gfd} JT is the actual flux at temperature T(gfd) T is the water temperature {°C) Speci�cations of the appraved BASF inge� dizzer� XL o.9 MB �o W UF modules: a) Polyethersulfone znodified (PESM) hollow fiber membranes with 7 capillaries per fiber; b) Naminal membrane pore size - 0.02 microns (µm}; c) Fiber inner diameter - a.g mm; d) Fiber outer diameter - q.o mm; e) Module diameter - 9.875 in.; f� Modnle length - 6�.� in.; g) No�ninal membrane surface area of 753-ft2; h) OperationaI mode: deposition; i) Maxirnum filtrate flux: �05 gfd at 2o°C; j) Operating temperature range of o°C (32°�) to 40° C(1o4°F); k} Maximum trans-membrane pressure of i.,5 bar; 1) Maximum feed pressure -� bar at 40° C; m) Operating pH range: r to i3; and, n) Maz�imum chlorine tolerance: 200,00o mg/L hours Dow IntegraFlaTM DWio2-iioo iTF Modules The TCEQ finds that the Dow IntegraFloTh� DW�o2-iioo UF module is accepted to vield a maximum of 62�q6� GPD of filtrate water (at 20° C) available for use by the City of Fort Worth Eagle Mountain Water Treatment Plan� customers for a 1,xo3-ft2 membrane elernent based on the following operating parameters of the pilot testing: Mr. Alan Davis, P.E.

Requirements for the Use of LTl#rafiltration Membranes The following ruZes apply to the use of the membrane treatment at the City af Fart Woa-th Eagle Mountain Wa�er Treatment Plant: 1) In accordance with 3o TAC §2ga.42(g} and §2go.39(I}, the approvaI to use UF membranes is site-specif c for the treatment of settled water from the Ciry of Fort Worth Eagle Mountain Water Treatment Plant (Plant ID No. �5o�a). 2) All treatment chemicaIs and media used in the full-scale facility must conform to ANSI/NSF Standard 6o for Drinking Water Tz•eatzTtent Cnemicals and ANSI/NSF Standard 6i for Drinking Wa�er System Cornponents and must be certified by an organization accredited by ANSI. This includes coagulants, disinfectants, anti-scalants, acids, caustics and other membrane cleaning chemzcaIs in accorc�ance with 3o TAC §29o.42(j}. 3} A revised Concentration Time (CT) study must be sui�mitted for TCEQ review and approval prior to delivery of potable water to t�e customers of the water system as specified in 3o TAC §290.Ill(�j�2�{B�. 4) Prior to delivery of potai�le water to the customers of the water system, t�e TCEQ must review and approve the direct integrity test (DIT) parameters %r the full-scale membrane faciiity as required by 3o TAC §29o.42(g)(3}(B). 5) In accardance with 3o TAC §2go.46(s)(2}{F), pressure monitors used for DIT measuremEnts shaIl be calibrated or verified at least once every �2 rnonths. 6) To prevent chemicals from the various membrane cleaning processes from contazninating other rnembrane units in other modes of ogeration, the membrane systems must have cross- connection protection for pipes handling feed water, filtrate, backwash, waste, and cnenrzicals. This may be accomplished by a double block-and-bleed valve arrangement, a removable spool systerr�, or other methods approved by the TCEQ (see 3o TAC §2go.42(g)(3}(F)). �) As required by 3o TAC §2go.46(e}{6}, the mernbrane fltration facilities must be operated and maintained at alI times under the direct supervision of an operator with a Ciass "B" or higher surface water license. The qualifi�d operator must be present anytime: a) T�ie membrane elements are replaced and/or repairs are made ta the membrane unit; Mr. Alan Davis, P.E. Page 6 November 30, 2oi� b) A CIP is performed; c} A direct integriry tes� is performed; d} Changes are made to the treatrnent process; or, e) The membrane units' operating parameters are changed. $) As required by 3o TAC §29o.ii1(f�(2), the water syst�m must monitor the performance of its filtration facilities. A qualified operator must be present at the meznbrane facility whenever water is being treated unless the rnembrane plant is provided with continuous monitors, alarms, and shutdowns. Specifically, the water system must provide: a) An alarzn system main�ained to sumznon #he operators in the event of an apparent degradatian in filtrate quality. The alarm must sumrnon the operators if an individual turbidimeter has t�vo consecutive readings above ioo mNTU (a.io NTU). b) Controls to automatically take a membrane unit out of service if the turbidity level rises above 1�4 mNTU (0.15 NTU) for two consecutive readings (as required by 3o TAC 29o.ixx(fl(2)(D)(v)). Pathogen Removal Credit in accordance with 3o TAC §2go.42(g)(3)(D), tk�e level of removal credit approved £or the City of Fort Worth Eagle Mountain Water Treatment Plant shall not exceed the lower of: • the removal eff ciency demonstrated during challenge testing, or • the maximum removal eff'iciency that can be verified through direct integriry testing.

E�Yceptions for the use of inembrane filtration are approved in accordance with the requirements in Title 30 of the TeYas Aclministrative Code (30 TAC) �290.42(g). Our letter, dated November 30, 2015, evaluated and approved the use of four membrane manufacturers for expansion of the membrane treatment facility for up to 35-mi]]ion gallons per day (NIGD) capacity. Your letter requested changes to the capacity calculations for each module based on either changes to the proposed membrane cleaning processes or corrections to our understanding of the cleaning processes demonstrated in the pilot study (as discussed in our approval letter dated November 30, 2015). We find the proposed changes and corrections to be acceptable, and with - this letter, we are revising our approval letter dated November 30, 2015, and are granling your request to use membrane treatment based on the site-specific performance recorded during the pilot study for the four manufacturers listed below. This letter replaces and supersedes our letter dated November 30, 2015. BASF inge' dizzeraXL 0.9 MB 70 WT UF Modules The TCEQfinds that the BASF inge° dizzer'XL 0.9 NIB 70 WT UF module is accepted to yield a maYisnum of 44,910 gallons per dav (GPD) of filtrate �vater (at 20° C) available for use by the City of Fort Worth Eagle Nlountain Water Treatment Plant customers for a 753 square-feet (ftZ) membrane element based on the following operating parameters of the pilot testing: • A backwash cycle of once every 30 minutes for a duration of 45 seconds; • A chemically enhanced backwash (CEB) twice each day for a duration of 66 minutes each cycle (33 minutes caustic cycle and 33 minutes acid cycle), resulting in a total backwash time of 132 minutes per day; • A total of 1,2 76 minutes per day in filtrate mode and 100 minutes per day in backwash mode or other maintenance activity; P.O.

Page 2 June 28, 2016 o For each BASF inge° clizzer�XL 0.9 MB 70 WT UF Module, 2,006 gallons are used per modt�le per dav for in-plant filtrate use; o A filtrate flux rate of 70.3 allons per square foot per day (gfd) at 20° C; and, • Based on the gross filtrate production of 49,283 GPD and the in-plant filtrate use of 2,006 GPD, the net filtrate capacity is 44,910 GPD per 753-ftZ module at 20° C. Based on our understanding of the submitted pilot study data, the TCEQ would issue a capacity rating of 35 million gallons per day (MGD) for a proposed surface water treatment plant (SWTP) design using 779 BASF inge' dizzer°XL 0.9 MB 70 WT LTF Modules. The TCEQ issues a net capacity rating for HF membrane facilities based on an instantaneous filtrate flu1Y corrected to 20° C. This rating is determined by subtracting the total in-plant use of filtrate (for backwashes, maintenance cleaning, and other in-plant use) from the gross potential filtrate production of a membrane unit. The TCEQunderstands and accepts that an increase in membrane ieed water temperature nornially results in �n increase in the fiitrate flux rate and a corresponding increase in potable water available for customer use. A decrease in water temperature will result in a reduction of the filtrate flux rate and a corresponding decrease in potable water available for customer use. This seasonal increase and.decrease of water temperature corresponds to the accepted increase of sunu�er and decrease of winter customer demands. This increased producrion shall have TCEQ approval provided it does not eYceed a temperatt�re-corrected filtrate flu.Y rate based on the followis�g ca1cL�lation from the United States Environmental Proteetion Agency (USEPA) Nlembrane Filtration Guidance Manual: Equation 2.10: 1,0 = JT Y[1.784 -(0.0575 Y T) +(0.0011 Y T') -(10�' Y T�) Where: J,o is the normalized flux at 20°C (gfd) JT is the actual flu�Y at temperature T(gfd) T is the water temperature (°C) Specifications of the approved BASF inge' dizzer9 XL 0.91��IB 70 WT ITF modules: a) Polyethersulfone modified (PESNI) hollow fiber membranes with 7 capillaries per fiber; bj Nominal membrane pore size - 0.02 microns (um); , c) Fiber inner diameter - 0.9 mm; d) Fiber outer diameter - 4.0 mm; e) Nlodule ctiameter - 9.875 in.; f) Module length - 67.7 in.; g) Nominal membrane surface area of 753-ftZ; h) Operational mode: deposition; i) Ma��mum filtrate flu<Y: 105 gfd at 20°C; j) �Operating temperature range of 0°C (32°F) to �0° C(10�°F); k) Maximum trans-membrane pressure of 1.5 bar; 1) Ma��mum feed pressure - 5 bar at 40° C; m) Operating�H range: 1 to 13; and, n) Nla��mum chlorine tolerance: 200,000 mg/L ours Dow IntegraFlo�"` DW102-1100 UF Modules The TCEQ finds that the Dow IntegraFloT"' DW102-1100 ITF module is accepted to vield a mal�mum of 63,31� GPD of filtrate water (at 20° C) available for use by the City of Fort Worth Eagle Mountain Water Treatment �Plant customers for a 1,103-ftz merribrane element based on the following operating parameters of the pilot t�sting: , Mr. Alan Davis, P.E.
