Overview
Aluminium Chlorohydrate, or ACH, is a cationic coagulant Suraj Chemicals supplies as a clear, slightly viscous liquid (CAS 12042-91-0) for water and wastewater clarification where a higher-performance alternative to conventional coagulants is needed. It removes colloidal, dissolved and suspended impurities — including anionic colloidal impurities and dyes — typically at a lower dosage than conventional coagulants and with negligible residual aluminium in the treated water, and it also works as a sludge dewatering aid. We supply it in 35/50 kg HDPE carboys and drums, with bulk quantities available on request.
