Water Treatment
Poly Aluminium Chloride (PAC)
Aln(OH)mCl3n-m
Pre-polymerized aluminium coagulant for drinking water, wastewater and industrial process water.
- Chemical name
- Polyaluminium chloride
- CAS number
- 1327-41-9
- Also known as
- PAC, Polyaluminum chloride
Product overview
Poly aluminium chloride is a pre-hydrolyzed inorganic polymer coagulant. Compared with conventional aluminium salts, it typically works across a wider pH range and produces less impact on alkalinity.
It is used for turbidity and color removal in drinking water, clarification of industrial and municipal wastewater, and as a retention aid in paper production. Basicity and aluminium content vary by grade and are confirmed on request.
Applications
Typical uses for this chemical. Suitability for a specific process, and grade requirements for food, pharmaceutical or potable-water use, should be confirmed with our team.
