Overview
Aluminium Sulphate, widely known simply as alum or non-ferric alum, is one of the oldest and most widely used coagulants in water treatment, and Suraj Chemicals supplies it as an off-white to light cream powder or lumps (CAS 10043-01-3) from our Chennai base. It's used as a primary coagulant in drinking water and municipal wastewater treatment, in effluent treatment plants for turbidity and colour removal, and in the paper industry for sizing, pulp processing and de-inking during recycling. We pack it in 50 kg HDPE/PP woven bags, with bulk supply available on request for larger treatment plants.
