Polyamine is a water-soluble cationic polymer used primarily as a coagulant and charge neutralizer in water and wastewater treatment. It is synthesized from epichlorohydrin and dimethylamine, giving it a strong positive charge density that effectively neutralizes negatively charged colloidal particles in water.Polyamine works well as a primary coagulant or as a coagulant aid in combination with inorganic coagulants (like PAC or alum) for color removal, turbidity reduction, and sludge dewatering.
