Fort Worth, TX 76118 Attention: Mr. Ben Davis, Renda Environmental, Inc. Biosolids Manager ; A Renda Environmental Inc. proposal for the application of Kemira Ferric Chloride at the Village Creek Water Reclamation Facility (VCWRF) Sludge Well #4 to enhance dewatering performance and reduce struvite formation. Kemira Water Solutions, Inc. would like to offer the following: Scope: A full-scale evaluation of Kemira Ferric Chloride at feed rate of 2 gallons per 800 gallons of sludge. The target start date will be November 20, 2014 and the trial period will be up to March 31, 2015 (120 days). During the trial period improvements and preparation for a permanent installation will be made to take over after March 31, 2015. It is important to note that Kemira recommends Renda Environmental Inc. to consider a sole-source contract based on performance. The trial equipment, product, personnel, rental, improvements, setup and breakdown cost for the project is listed on page 3. There are no other additional costs associated with the project.

Initial Feed Rates: We would propose commencing the Kemira PIX 116 evaluation utilizing an initial feed rate of 2 gallons Kemira PIX 116 per 800 gallons of sludge (also based on dewatering benefits such as reduced polymer demand, increased cake solids and reduced ortho-phosphate levels). Based on the dosages mentioned, the expected Ferric Chloride consumption will be 2880 gallons per day. The feed rate will be optimized during the course of the evaluation. Equipment and Detail: The equipment required to effectively introduce Kemira PIX 116 until March 31, 2015 includes: • One (1) bulk Storage tanks (6500 Gallons capacity) • 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. • 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 pumps will have a calibration column • Sufficient hoses and extension cords needed to operate and flush pump • Hoses and fittings required to effectively introduce Kemira PIX 116 at the targeted location • An air compressor for air mixing in the sludge well • Equipment set-up and tear-down fees 3 Trial Equipment, Rental and Setup Fees: Kemira would provide the Ferric Chloride and equipment, including storage tanks, pumps, personnel trial services, hoses, fittings, travel, delivery and pickup. Renda Environmental Inc. would be responsible for an all-inclusive price per Lb. cost of the Ferric Chloride and equipment cost. Product: Kemira PIX (30-37% Ferric Chloride) Kemira PIX 116 and Equipment Price: $0.1264 per Lb. delivered. Feed rate = 2 gallons PIX 116 per 800 gallons sludge = 2 X 1440 gallons Kemira PIX 116 per 800 X 1440 gallons sludge per day. 2880 gallons Kemira PIX 116 per day for a 120 day trial = 345,600 gallons of Kemira Ferric Chloride. 1 1 .18 Lbs. /gallon X 345,600 gallons = 3,863,808 Lbs. of Kemira PIX 116. 3,863,808 Lbs. X $0.1264 per gallon delivered = $488,385.33 for a 120 day trial. Shipment will be via full bulk truckload (approximately 4,200 gallons per shipment) quantity. Trial services, monitoring and optimization is included in this product price. 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. 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 and the VCWRF staff.
