Product overview
Poly Aluminium Chloride (PAC) is a pre-polymerised inorganic coagulant that outperforms conventional alum and ferric salts across a broader pH range, without needing separate coagulation aids.
Floc forms faster and settles more completely than with simple aluminium or iron salts, and performance is less affected by water temperature — making it a preferred coagulant for both municipal and industrial water treatment plants.
Applications
Municipal drinking water treatmentIndustrial & textile wastewater treatmentPaper mill effluent treatmentBroad pH-range coagulationLow-temperature water treatmentSludge dewatering aid
