• Four (4) storage tanks with the capacity of 12,000 gallons each. <br />• One (1) overflow tank with the capacity of 4,100 gallons each. <br />2.12 EPICHLOROHYDRIN DIMETHYLAMINE POLYAMINE <br />All Epichlorohydrin dimethylamine polyamine polyelectrolytes (EPI-DMA) must meet American National <br />Standards Institute (ANSI)/American Water Works Association (AWWA) Standard B452-20. This might also <br />be identified as liquid cationic polyelectrolyte. The liquid EPI-DMA polyelectrolyte shall be potable water <br />treatment grade, in aqueous suspension, of a concentration not less than 50% by weight active polymer. <br />The City will only accept the below approved polyelectrolytes for use at the Water Filtration Plant: <br />• Nalco 8105 <br />• Diafloc 3495 <br />• Ciba Magnafloc LT-7981 <br />• Sweetwater B-150 <br />• Summit Sumaclear P-10 <br />• Jes Chem PA-16 <br />• Hexafloc 500L <br />• Clarifloc C-339 <br />Suppliers seeking approval of their liquid polyelectrolyte for inclusion on the list of eligible products must <br />provide technical information and specifications with their price sheet submittal. <br />The supplier's agent shall provide samples for the City. The samples will be held in borosilicate glass jars. <br />The City shall retain one (1) sample from each shipment. <br />Each shipment must be accompanied by a Certificate of Analysis, which shall include, but is not limited to, <br />the following information: <br />1. Product name <br />2. Batch number <br />3. Date of manufacture <br />4. Weight per gallon and temperature <br />5. Neat viscosity and temperature <br />6. Parts per million epichlorohydrin monomer residual <br />7. Specific gravity <br />8. Nephelometric turbidity units <br />9. Color <br />The supplier must be able to deliver bulk shipments of 4,000 to 5,000 gallons. <br />Page 14 of 27 <br />
