Poly Aluminium Chloride (PAC) is a high-efficiency inorganic polymer coagulant widely used in water purification industry. It features strong adsorption, fast floc formation, large and compact flocs, and excellent sedimentation performance. Compared with traditional ferric sulfate and aluminum sulfate, PAC has lower dosage, wider applicable pH range and less residual metal ion in treated water.
