CATIONIC POLYMER FOR WATER CLARIFICATION AND SLUDGE DEWATERING

摘要

Methods of clarifying wastewater and of dewatering sludge are disclosed. The methods comprise adding to the wastewater or the sludge an effective amount for the purpose of a polymer comprising repeat unit moieties of methacryloyloxyethyl trimethyl ammonium chloride, said polymer having an intrinsic viscosity from about 1.0 to about 4.5 dl/g.
