Poly Aluminium Chloride (PAC)
[Al₂(OH)ₙCl₆₋ₙ]ₘ
A pre-polymerised aluminium coagulant that works across a wider pH range than alum and forms flocs faster, often at a lower dose. It leaves less residual aluminium and less sludge.
Applications
- Drinking water clarification
- Industrial and municipal effluent
- Paper sizing and retention
- Textile wastewater colour removal
Grades & forms
Powder, typically 28–31% Al₂O₃, in yellow (industrial) and white (drinking water) grades; liquid grade on request.
