ABSTRACT:
A method of flocculating coagulated and/or finely divided suspended matter in aqueous systems comprising adding to the system from 0.005 to 1 weight percent based on the dry weight of the coagulated and/or finely suspended matter of at least one water soluble cationic polymer selected from a water soluble cationic copolymer (I) composed of the polymerization reaction of an N-vinylamide with at least one cationic quaternary amine monomer.
