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 (FAQ)
Q
What is Solid PAC (Poly Aluminum Chloride) and how does it work?
Solid PAC is a high-efficiency inorganic coagulant used in water purification. It works by forming large, dense flocs through adsorption and charge neutralization, rapidly coagulating suspended solids, colloids, and organic matter in water. Its large molecular structure enables fast sedimentation and effective dewatering of sediment.
Q
What is the difference between Industrial Grade and Drinking Water Grade Solid PAC?
The main differences lie in purity and heavy metal content. Drinking Water Grade has a higher Al2O3 content (≥ 29%), significantly lower limits for heavy metals such as Fe (≤ 0.2%), As (≤ 0.0001%), Cr (≤ 0.0005%), Hg (≤ 0.00001%), Pb (≤ 0.0005%), and Cd (≤ 0.0001%), making it safe for potable water treatment. Industrial Grade is suitable for wastewater and process water applications.
Q
What types of wastewater is Solid PAC suitable for?
Solid PAC is suitable for a wide range of water treatment applications including drinking water pre-purification, municipal sewage treatment, and industrial wastewater from sectors such as electroplating, printing and dyeing, papermaking, coal washing, and oilfield reinjection water clarification. Its applicable pH range of 4–10 makes it highly adaptable to various water qualities.
Q
How should Solid PAC be dissolved and dosed?
Solid PAC dissolves completely within 3 minutes at room temperature. It requires a low dosing amount, leaves no residue after dissolution, and significantly reduces the risk of equipment blockage. The concentration can be precisely controlled after dissolution, making it easy to integrate into existing dosing systems.
Q
What are the packaging options and shelf life for Solid PAC?
Solid PAC is available in 25kg woven bags lined with plastic bags, or in 1-ton jumbo bags (customizable for bulk orders). 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). Its solid form also makes it ideal for long-distance transportation.
Q
Can the Al2O3 content and basicity of Solid PAC be customized?
Yes. Solid PAC offers flexible customization options. The Al2O3 content can be specified between 28% and 30%, and the basicity is adjustable from 40% to 90%, allowing customers to tailor the product to their specific water treatment requirements and process conditions.
