Polyaluminium Chloride (PAC) Comprehensive Guide High-Efficiency Water Treatment Solution for Improved Water Quality
1. What is Polyaluminium Chloride (PAC)?
Polyaluminium Chloride (PAC), with the chemical formula Al2(OH)nCl6−nAl2(OH)nCl6−nₘ, is a highly efficient inorganic polymer coagulant. Produced through the hydrolysis and polymerization of aluminum salts, PAC boasts strong adsorption capabilities, rapid flocculation, and adaptability across a wide pH range. It is widely used in drinking water purification, industrial wastewater treatment, urban sewage management, and more.
2. Key Applications of PAC
Drinking Water Treatment
PAC effectively removes suspended solids, heavy metals, and microorganisms, ensuring compliance with WHO and GB5749-2022 standards for safe drinking water.
Industrial Wastewater Treatment
Ideal for electroplating, textile, pharmaceutical, and chemical industries, PAC reduces COD (Chemical Oxygen Demand) and BOD (Biological Oxygen Demand) by accelerating pollutant sedimentation.
Paper Manufacturing
Acts as a sizing agent to enhance paper strength and minimize wastewater discharge, supporting eco-friendly production.
Oilfield Reinjection Water Treatment
Prevents pipeline corrosion and scaling, improving oilfield operational efficiency.
Urban Sewage Recycling
Reduces sludge treatment costs and promotes sustainable water reuse.
3. Why Choose PAC?
✅ High Efficiency & Energy Savings: Dosage is 1/3 of traditional aluminum salts, with 40% faster flocculation.
✅ Eco-Friendly & Safe: Non-toxic residues; compliant with EU REACH and US EPA standards.
✅ Broad Adaptability: Works effectively in pH 5.0–9.0 and performs well in low-temperature, high-turbidity water.
✅ Cost-Effective: Reduces sludge disposal costs by over 30%.
