Product Description
Polyaluminium Chloride (PAC) Liquid - High Efficiency Coagulant for Water Treatment
Polyaluminium Chloride (PAC) is a highly efficient inorganic polymeric coagulant that exists in an intermediate state between AlCl₃ and Al(OH)₃. Characterized by a highly charged, polynuclear complex structure, PAC serves as a core chemical in modern water treatment technology with exceptional properties including broad pH adaptability, rapid formation of dense flocs, fast settling speed, high efficiency in removing turbidity and color, low dosage requirements, and minimal corrosivity.
Core Applications & Industry Solutions
Safe Drinking Water Purification
PAC is the preferred coagulant for water treatment plants and advanced drinking water systems. It efficiently removes suspended particles, colloidal substances, microorganisms, natural organic matter (including humic acids), and heavy metals from raw water. The resulting flocs are coarse and dense with excellent settling properties, while residual aluminum content remains controllable and compliant with national drinking water standards (GB 5749).
Industrial and Municipal Wastewater Treatment
PAC demonstrates strong versatility in treating various industrial wastewaters from papermaking, textile dyeing, electroplating, food processing, pharmaceuticals, and petrochemicals, as well as municipal sewage. For challenging wastewater with high concentrations, color, and complex compositions, PAC effectively breaks emulsions, removes phosphorus, reduces COD, and eliminates heavy metal ions through charge neutralization and adsorption bridging.
Paper Industry Applications
In papermaking processes, PAC serves as both a neutral sizing precipitant and retention/drainage aid. It improves fine fiber and filler retention, enhances paper formation and strength, optimizes dewatering properties, reduces white water concentration, and minimizes environmental pollution while saving raw materials.
Additional Industrial Applications
PAC finds innovative uses across multiple industries including:
- Precision casting - as a shell hardening agent
- Cosmetics - raw material for antiperspirants
- Pharmaceuticals - as an astringent
- Leather tanning and oil-water separation processes
