Overview
Poly Aluminium Chloride, or PAC, is the primary liquid coagulant Suraj Chemicals supplies for water and wastewater treatment — a pale yellow liquid (CAS 1327-41-9) that typically performs at a lower dosage than conventional alum. We supply it to drinking-water treatment plants, effluent and industrial wastewater facilities, and to paper mills and tanneries for sizing, de-inking and wastewater clarification, shipping from our Chennai base in 35/50 kg HDPE carboys and drums, IBC totes, or bulk tanker for larger plant requirements. See the characteristics table below for the current batch's assay, and contact us for pricing against your required dosage and volume.

Buyer’s Notes
Choosing the grade. This liquid is about 10.4% Al2O3, pale yellow, specific gravity 1.255. Compare liquid PAC suppliers by price per kg of Al2O3, not by price per kg of liquid.
What to check on the spec sheet. Al2O3 content, basicity, specific gravity, pH of a 5% solution (2.7 on this report) and iron. Always jar-test against alum or your present coagulant.
Handling and storage. Acidic and corrosive to mild steel. Use HDPE, FRP or rubber-lined tanks and pumps, store in a cool, shaded place and away from alkalis.
Where it is used. Drinking-water treatment, effluent clarification, paper sizing and tannery and textile wastewater.
