HEARING:
SUBJECT: Authorize the Execution of Change Order No. 13 to City Secretary No. 30908 with Renda
Environmental, Inc.,for the Village Creek Water Reclamation Facility Solids Dewatering,
Processing and Disposal Program and Gas Turbine Operations and Maintenance
Contract to Continue to Provide Chemical Treatment of Liquid Sludge, Increasing the
Contract in the Amount of$520,000.00 for a Revised Total Program Cost of
$70,399,067.16(COUNCIL DISTRICT 5)
RECOMMENDATION:
It is recommended that the City Council authorize the execution of Change Order No. 13 to City Secretary Contract No. 30908 with
Renda Environmental, Inc.,for the Village Creek Water Reclamation Facility Solids Dewatering, Processing and Disposal Program
and Gas Turbine Operations and Maintenance Contract,to continue to provide chemical treatment of the liquid sludge from the
Village Creek Water Reclamation Facility, increasing the contract cost by$520,000.00 for a revised total program cost of
$70,399,067.16.
DISCUSSION:
On April 6,2010(M&C C-24163),the City Council authorized the third five-year renewal of the Solids Dewatering, Processing and
Disposal Program and Gas Turbine Operations and Maintenance Contract with Renda Environmental, Inc. (RENDA). The contract
includes the dewatering, processing and disposal of approximately 110 dry tons per day of biosolids for the City of Fort Worth and
its wholesale customer cities and the operation and maintenance of two 5.2 megawatt gas turbine generators at the Village Creek
Water Reclamation Facility(VCWRF).
On May 05,2015(M&C C-27287),the City Council authorized an amendment and settled claims to the Solids Dewatering,
Processing and Disposal Program and Gas Turbine Operations and Maintenance Contract with RENDA related to operational
changes,increased landfill gas cost and other modifications to the contract for an estimated cost of$67,330,360.16. This
amendment also included funding for RENDA to provide treatment of liquid sludge with ferric chloride through September 30,
2015. This chemical treatment improves the odors associated with biosolids production,transportation,and land application
activities. It also improves the dewatering characteristics of the biosolids which reduces costs incurred by the City.
This proposed Change Order No. 13 addresses the need to continue with chemical treatment of the liquid sludge from October 1,
2015 to January 31,2016. The total contract will be$70,399,067.16. The total cost for the purchase of chemicals for this
treatment shall not exceed$520,000.00 for the specified timeframe.

Attention: Mr. Ben Davis, Renda Environmental, Inc. Biosolids Manager
Ref: The Village Creek WWTP and/or Renda Environmental Inc. proposal for the application
of Kemira's Auto-Optimized Dosing System for Dewatering. Application of a fully optimized
dewatering treatment program to include: Kemira Remote Contaminant Control &
Monitoring Technology (a.k.a. RCCMT), feed equipment, and chemistries at the Village Creek
Water Reclamation Plant and the Renda Environmental Inc. operated Biosolids facility.
Kemira Water Solutions, Inc. would like to offer the following:
Kemira Scope:
The continuation of the full-scale evaluation of Kemira's Auto-Optimized Treatment Program.
The project start date was April 1, 2015 and it will continue until December 31, 2015. Provisions
will be made for multiple extensions, if agreed upon by both parties. Our intention is to
provide our customer access to one of Kemira latest advanced technologies. Kemira wishes
to enter into a long-term mutually-benefitting relationship. We will provide this technology at
no additional charge, provided that we can share the data generated from the project and
that the provisions of the chemical supply contracts continue.
The ultimate aim is to provide consistently higher % cake solids, regardless of the changes in
flow or solids content. The other aim is to lower the overall treatment costs, as much as
possible. The inorganic coagulant will be optimized based on flow, conductivity, and TDS. All
of this will occur with real-time reactivity. All data will be shared via the Kemira G2 Portal.
Automatic monthly reports will be written and provided to The Village Creek WWTP and
Renda Environmental Inc.
Requirements from Renda Environmental Inc.:
We ask that The Village Creek WWTP and Renda Environmental Inc. provide: a cut-out and
welded double-flanged 4" section of pipe for the TS meter, a tapped valve for the TSS meter,
a local electrical source, and a local clean water source. Details on the installation are
provided.

Kemira will also provide a second mag-flow meter to be placed on the discharge side of one
existing polymer feed pump. This installation should be done by The Village Creek WWTP
and/or Renda Environmental Personnel. This mag-flow meter is required to validate actual
polymer dosage rate versus targeted dosage rates. In addition, a Kemira PLC will be
mounted (by Kemira personnel) close to the existing polymer pump speed controller (VFD).
This PLC will be used to automatically control the polymer pump speed based on inputs from
the Kemira Master PLC. This PLC should be wired in by Village Creek WWTP and/or Renda
Environmental Personnel, with guidance from Kemira Field Electrical Engineers (unless
otherwise agreed to by both parties).
Auto-Optimized Chemical Feed Rates: We are proposing auto-optimized feed rates versus
maintaining the existing feed rates of estimated 122 Lbs. neat ferric chloride/DT of solids. The
feed rate will be optimized during the course of the evaluation by several methods. First and
foremost, there will be accurate reporting of actual feed rates based on mag-flow meter
outputs for the total FeC13 feed. Utilizing TS, conductivity, TSS, and TDS measurements taken in
real time; the total inorganic chemical feed demands will be auto-calculated. As a final
check, these auto-calculated outputs will be measured against actual dosage rates.
Equipment and Detail:
The equipment required to effectively optimize dosage rates includes:
• One (1) bulk Storage tank (10,500). The Village Creek WWTP and/or Renda
Environmental Inc. must provide a compacted level surface.
• The Bulk Storage Tank will be fitted with an Ultrasound Level Transducer that will relay
real-time tank level data (with alarms) to Kemira logistics personnel. This will help
ensure that they product does not run out.
• One containment or berm for the bulk storage tank and pump skid.
• One sump pump for the containment in case of spills and wash water.
4
• One pump skid with two (2) chemical pumps (3 gallons per minute capacity). One of
the two pumps will be a back-up pump. The pump skid will now have a magflow
meter.
• Sufficient hoses and extension cords needed to operate and flush pump
• Hoses and fittings required to effectively introduce Kemira PIX 1 16 at the targeted
location
• An air compressor for air mixing in the sludge well
• Several PLC SCADA Units located at various locations. These PLCs are designed to
feed data to a central PLC via radio communication. The main PLC will be located at
the ferric chloride feed site. Another will be located at the TS and TSS sensor location.
And, a third will be located at the polymer feed pump location.
• A TS Wafer Sensor mounted on a digestor effluent line.
• A TSS Optic Sensor (with a saddle for tap included) on the same digestor effluent line.
• Equipment set-up and tear-down (with the exception of cut and tapped lines) is
included.
Governance:
Kemira would provide the auto-optimized dosing equipment plus the chemical feed
equipment. Kemira will share all the data collected during the trial. Kemira will wire and
radio in all of its own equipment and mount PLCs in The Village Creek WWTP' and/or Renda
Environmental Inc.' approved locations.
The Village Creek WWTP and/or Renda Environmental Inc. will be responsible for cutting and
flanging a 4" section of pipe. The Village Creek WWTP and/or Renda Environmental Inc. will
also be responsible for tapping the same line for a valve. Kemira will provide the saddle for
the sample tap. The Village Creek WWTP and/or Renda Environmental Inc. will be responsible
for installing a Kemira supplied mag-flow meter. It will also be responsible for providing wire
connections from the designated polymer speed pod controller to the Kemira PLC.
Kemira will make provisions to keep the equipment on-site, as long as The Village Creek
WWTP and/or Renda Environmental Inc. continues to utilize Kemira' chemistries to optimize its
dewatering process. If the current contract ends on December 31, 2015, the auto-optimized
feed equipment will need to be removed within a thirty (30) day period at the end of the
existing contract (unless agreed upon by both parties to continue the treatment). Kemira will
provide a fitted plug to replace the gap where the original TS Sensor was placed.
Products:
Kemira PIX-1 16(30-37% Ferric Chloride) and/or PIX-1 1 1 (38-42% Ferric Chloride) and Equipment
Price: $0.1264 per Lb. Delivered.
• Production of PIX-1 16 (30-37% ferric chloride) is scheduled to be discontinued by the
end of September 2015. After discontinuation of production of this product, Kemira
will supply PIX-1 11 (38-42% ferric chloride) at the above price through the end of
December 2015.

Customer Requirements
The trial equipment will require access to electrical outlets (120V) and service water for
routine PMs (Cleanings and Maintenance) at the injection site and at the various monitoring
devices. Monthly calibrations will be required. Therefore, extra monthly samples (at least 4-6
samples) will be submitted to The Village Creek and/or Renda Environmental Laboratory to
confirm the calibrations.
Please do not hesitate to contact either Mark Hust or myself at any time. We look forward to
continuing to work with you, the Renda Environmental Inc. staff.
