Cationic Polyacrylamide (CPAM)
Cationic polyacrylamide is a water-soluble polymer with positively charged groups that make it highly effective for flocculating negatively charged suspended particles and colloids. It is extensively used in sludge dewatering, paper manufacturing, and municipal wastewater treatment. Its cationic nature allows direct interaction with negatively charged biomass and organic matter for rapid floc formation.
