Drinking Grade Polyaluminum Chloride (PAC)
Polyaluminum chloride (PAC) is an advanced inorganic coagulant used in water treatment processes. Drinking grade PAC is specially formulated to meet safety and purity standards for potable (drinking) water treatment.
What is PAC?
Polyaluminum chloride is a high-performance coagulant with the chemical formula [Al₂(OH)nCl₆–n]m, where the polymeric structure enhances coagulation efficiency compared to traditional coagulants like aluminum sulfate.
Key Features:
-
Appearance: Light yellow or white powder or liquid
-
Aluminum Content: Typically 28–30% (as Al₂O₃)
-
Basicity: 40–70% (varies by product grade)
-
Solubility: Completely soluble in water
-
pH Range for Use: Effective in a wide pH range (5.0–9.0)
Applications:
-
Drinking Water Treatment: Removes suspended solids, turbidity, organic matter, heavy metals, and pathogens.
-
Municipal Water Plants: Used in clarifiers and sedimentation tanks for efficient coagulation and flocculation.
-
Pre-treatment for RO Systems: Helps improve membrane lifespan by reducing fouling.
Benefits:
-
Produces less sludge than traditional coagulants
-
Rapid coagulation and floc formation
-
Works effectively over a wide range of temperatures and pH
-
Low residual aluminum levels in treated water
-
NSF/ANSI or equivalent certified for drinking water (if applicable)
