Poly Aluminium Chloride 30% (PAC)

Poly Aluminium Chloride 30% (PAC) (CAS 1327-41-9, molecular formula Al2Cln(OH)6-n) is a treatment chemical specified by municipal and industrial plant operators where dose consistency and impurity control directly affect finished water quality. China Chemicals supplies it at Al2O3 30% min in pack sizes from 1 kg through to 1000 kg Bulk Bag, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as PAC, Polyaluminium Chloride, Aluminium Chlorohydrate. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Primary coagulant in drinking water treatment
Turbidity and colour removal in municipal plants
Industrial effluent and paper mill clarification
Phosphate removal in wastewater
Sludge conditioning and dewatering support
