Specifications include, but are not limited to: I. POLYMER SPECIFICATIONS PolyDADMAC is used in water treatment to improve the performance of some unit operations in the treatment process, most often by increasing the extent or rate of liquid-solids separations. The DADMAC monomer used to make Poly DADMAC is made from two chemicals: allyl chloride and dimethylamine. PolyDADMACs have a cationic charge, a high relative charge density, and low-to-medium relative molecular weights. Approved: Three (3) products have been approved by District: 1. Cat Floc 8102 PLUS 2. DADMAC C308P. 3. Magnafloc® LT-7985 If there are other products that can meet these requirements please submit to District for testing and possible approval for next Invitation for Bid. District will determine their polymer needs based on jar testing, pilot plant testing, or operational testing. The best product for the job will be selected. Supplier is encouraged throughout the term of this Agreement to present new products for testing. II. CATIONIC POLYMER Product shall meet the NSF/ANSI Standard No. 60 for Drinking Water Treatment Chemicals - Health Effects and AWWA standard B451, of latest revision, for Poly(Diallyldimethylammonium Chloride) water supply service applications. 1. Impurities: The polymers shall contain no mineral or organic substances in quantities capable of producing deleterious or injurious effects on the health of those consuming water that has been properly treated with it. 2. Heavy Metals: All products purchased under this contract shall be free of heavy metals.
