The product shall be a cationic copolymer of acrylamide. The product shall contain no formaldehyde. Active solids concentration must be a minimum of 40%. C. The polymer materials shall have a shelf life of at least six months at ambient temperatures. D. The polymer materials in both concentrated and diluted form shall not require special handling, nor shall they pose hazards to employees working with them. E. The polymer shall not contain any substances which are inhibitory or toxic to bacteria essential to wastewater treatment processes. F. The materials shall not cause corrosion problems to the City’s equipment. The polymers must be compatible with the City’s existing storage and handling facilities. G. The product must meet the following performance specifications for each of the City’s wastewater treatment plants.
