Poly Aluminium Chloride (PAC)
Alₙ(OH)ₘCl₍₃ₙ₋ₘ₎ | CAS: 1327-41-9 | HS: 28273200
Product Description
Poly Aluminium Chloride is the advanced-generation coagulant that is rapidly displacing conventional alum in modern drinking water treatment plants worldwide. Its pre-hydrolysed aluminium chain structure delivers superior coagulation at significantly lower dosages, reducing sludge volume, minimising residual aluminium in treated water, and maintaining effectiveness across a broader pH range than alum. MITCHEM exports high-alumina PAC powder (28–32% Al₂O₃) to municipal water utilities, industrial effluent plants, and paper mills across the Middle East, South Africa, and Southeast Asia with full quality documentation.
Applications by Industry
Primary coagulant in modern water treatment plants; lower dosage requirements, smaller sludge footprint, and wider pH operating range versus alum make it the preferred choice for new-build and upgraded municipal plants.
Highly effective in treating high-suspended-solids industrial effluents from textiles, paper, food processing, and chemical industries; rapid floc formation reduces settling tank residence time.
Used as a retention aid and filler retention agent in paper machine wet end chemistry, improving filler retention and drainage at near-neutral pH.
Applied in textile effluent treatment to coagulate reactive and direct dye residues, reducing COD and colour in discharge water.
