A. LIQUID CATIONIC POLYMER John Jones Water Treatment Plant – Bulk Supply/Delivery a. Quality i. The liquid cationic polymer shall contain no substances in quantities capable of producing deleterious or injurious effects upon the health of those consuming the water to which the liquid cationic polymer has been added or causing water so treated to fail to meet the requirements of the California Domestic Water Quality and Monitoring Regulations. ii. The liquid cationic polymer delivered under this agreement shall conform to the following: • USEPA approved for use in potable water at dosages up to 50mg/1 • Free of biological contamination; and • No more than 5mg/l iron. • Liquid polymers delivered to the Wastewater Treatment Plant need not meet potable water standards. b. Affidavit of Compliance i. The Contractor shall submit an affidavit of compliance with the following specifications for each delivery of liquid cationic polymer as delivered to the John Jones Water Treatment Plant bulk storage tanks. ii. The affidavit of compliance shall contain: • Percent active polymer • Pounds per gallon • Date of manufacture. c. Certified Laboratory Report i. A certified laboratory report to meet NSF Standard 60 shall be submitted for the first liquid cationic polymer delivery to the John Jones Water Treatment Plant and when a significant change occurs in the Contractor’s manufacturing process. This report shall contain the following: • Percent active polymer • Pounds per gallon • Date of manufacture • Specific gravity • Iron content • pH ii. Charges for the certified laboratory reports shall be included in the bid price. d. City Approved Cationic Polymers The following are the only currently City-approved cationic polymers to be used in the Water Treatment Plant: Manufacturers Products Calgon Corporation Cat Floc-T, Cat Floc-C, Cat Floc-T2, Cat Floc-C2 Nalco Nalco 8102, Nalco E-792 Allied Colloids Inc. Percol 775, 778 Polydyne C – 4420 e. Qualification Requirements for City Approval To achieve City approval, for future bid purposes, a prospective Contractor’s liquid cationic polymer shall meet the following requirements: i. All the requirements of these specifications. ii. Performance criteria established by the City: • A screening evaluation conducted on a laboratory scale, performed by City personnel. The Contractor shall furnish at least 100 ml of liquid cationic polymer for this evaluation. • If the laboratory evaluation demonstrates the liquid cationic polymer to be effective, under laboratory condition, then a plant-scale evaluation shall be performed. • For the plant-scale evaluation, the prospective Contractor shall furnish liquid cationic polymer in the amount established by the City to be able to run the evaluation for a seven (7) day run supplied at prospective Contractor cost. Also, to re-evaluate if process conditions warrant; for example: if major changes occur in nature of feed solids. • Performance evaluations shall be performed at the convenience of the City and may be witnessed by the prospective Contractor. • A copy of the City’s performance evaluation procedure shall be furnished on request. iii. No prospective liquid cationic polymer shall be screened at the John Jones Water Treatment Plant without introduction by prospective Contractor personnel.
