High-Quality Poly Aluminium Chloride (PAC) Powder Granules from China Suppliers & Factory - Low Dust, No Caking
Core Features
High-Efficiency Water Purification: Large molecular structure, strong adsorption capacity, rapid formation of flocs, high sedimentation speed, short reaction time, and good dewatering performance of sediment. It rapidly coagulates suspended solids, colloids, and organic matter, with a turbidity removal rate ≥95% and a COD removal rate ≥40%.
Highly Customizable: Al₂O₃ content 28%-30% (optional), basicity adjustable from 40% to 90%.
Strong Adaptability: Applicable pH range is 4-10, resistant to high turbidity and high salinity water quality (printing/dyeing/paper-making/chemical wastewater). Water-insoluble matter ≤0.5%.
Convenient Dissolution: Completely dissolves in 3 minutes at room temperature, with low dosing amount and no residue.
Transportation and Storage: Solid form is convenient for long distance transportation, with a storage period of up to 2 years.
