Poly Aluminium Chloride (PAC) is a high-performance inorganic coagulant for water and wastewater treatment, offering superior floc formation over conventional alum at a wider pH range.
Inquire About This ProductPoly Aluminium Chloride (PAC) is an inorganic polymer coagulant used extensively in water and wastewater treatment. It offers superior coagulation performance over conventional aluminium sulphate across a broader pH range (5.0–9.0), forming dense, fast-settling floc with lower sludge volumes.
Our PAC is available in both liquid (solution) and powder form and is suitable for potable water, industrial effluent and municipal wastewater treatment. It complies with SANS and international standards for potable water treatment chemicals and is supplied with a Certificate of Analysis.
