Poly Aluminium Chloride (PAC) Granules - High-Quality China Suppliers and Factory, Low Dust, Uniform Particle Size
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 (applicable to printing and dyeing / paper-making / chemical wastewater); the pH of the treated effluent changes little. Water-insoluble matter ≤0.5% (better than national standard), with no residual impurities.
Convenient Dissolution: Completely dissolves in 3 minutes at room temperature, with low dosing amount, no residue, and reduces the risk of equipment blockage.
Convenient Transportation and Storage: The solid form is convenient for long distance transportation, has a storage period of up to 2 years and the concentration can be controlled after dissolution.

Frequently Asked Questions
Q
What is Solid PAC and how does it differ from liquid PAC?
Solid PAC (Poly Aluminium Chloride) is a dry, granular or powder form of the coagulant, offering higher Al₂O₃ content (28%–30%) compared to liquid PAC. It is easier to transport over long distances, has a longer shelf life of up to 2 years, and allows users to precisely control the concentration after dissolution on-site.
Q
What turbidity and COD removal rates can Solid PAC achieve?
Solid PAC achieves a turbidity removal rate of ≥95% and a COD removal rate of ≥40%, making it highly effective for treating both municipal and industrial wastewater with high suspended solids and organic matter content.
Q
What types of wastewater is Solid PAC suitable for?
Solid PAC is suitable for a wide range of applications including drinking water pre-purification, municipal sewage treatment, industrial wastewater from electroplating, printing and dyeing, and papermaking industries, as well as coal washing and oilfield reinjection water clarification. Its effective pH range of 4–10 makes it adaptable to diverse water quality conditions.
Q
How quickly does Solid PAC dissolve, and how should it be dosed?
Solid PAC completely dissolves within 3 minutes at room temperature. It requires a low dosing amount, leaves no residue, and significantly reduces the risk of equipment blockage. It is recommended to dissolve it in water first to form a solution before adding it to the treatment system.
Q
What are the packaging options and shelf life of Solid PAC?
Solid PAC is available in 25kg woven bags lined with plastic bags, or in 1-ton jumbo bags (customizable). When stored in a cool, dry place and protected from moisture and physical damage, the product has a shelf life of up to 2 years (unopened).
Q
What is the difference between Industrial Grade and Drinking Water Grade Solid PAC?
The Drinking Water Grade has stricter quality standards: a higher minimum Al₂O₃ content (29.0% vs 28.0%), lower insoluble substances (≤0.1% vs ≤0.4%), and significantly lower heavy metal limits for Fe, As, Cr, Hg, Pb, and Cd, ensuring safety for potable water treatment. Industrial Grade offers broader basicity flexibility (20–98%) for diverse industrial applications.
