Poly Aluminum Chloride (PAC) Coagulant for Water Treatment
Poly Aluminum Chloride (PAC) is a highly effective water treatment coagulant widely used in municipal and industrial water and wastewater purification systems. Compared to traditional coagulants such as alum and ferric salts, PAC offers faster settling, better turbidity removal, and improved performance over a wider pH range.
PAC is manufactured through controlled hydrolysis of aluminum chloride or aluminum hydroxide, producing a polymeric aluminum compound that combines strong coagulating power with reduced sludge production.
What Is PAC Coagulant?
PAC (Poly Aluminum Chloride) is a highly polymerized aluminum salt used as a primary coagulant in water purification. When added to raw or wastewater, PAC destabilizes colloidal particles, promoting aggregation into larger flocs that can be removed by sedimentation or filtration.
Unlike traditional coagulants, PAC performs efficiently over a wide pH range, requires lower dosages, and often produces less sludge, making it cost-effective and easier to manage.
Key Features & Benefits
- High coagulation efficiency for water and wastewater clarification
- Improved turbidity removal compared to alum
- Effective across a wide pH range
- Lower sludge volume
- Faster settling and clearer effluent
- Ideal for municipal and industrial systems
Typical Applications
PAC coagulant is widely used in:
1. Municipal Water Treatment
Improves potable water quality by removing suspended solids, colloids, and organic matter.
2. Industrial Wastewater Treatment
Removes industrial contaminants and heavy metals, and helps meet discharge standards.
3. Cooling Tower and Boiler Feed Water
Controls turbidity and corrosion to protect process equipment.
4. Paper & Pulp, Textile & Dye Effluent Treatment
Helps clarify process water for reuse or discharge.
