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
QWhat is Solid PAC (Poly Aluminum Chloride) and how does it work?
Solid PAC is a solid-form inorganic coagulant used in water purification. It works by releasing aluminum ions when dissolved in water, which rapidly form flocs that adsorb and bind suspended solids, colloids, and organic matter, allowing them to settle quickly. This results in a turbidity removal rate of ≥95% and a COD removal rate of ≥40%.
QWhat is the difference between Industrial Grade and Drinking Water Grade Solid PAC?
The primary differences lie in purity and heavy metal content. Drinking Water Grade has a higher minimum Al2O3 content (29.0% vs 28.0%), much lower limits for heavy metals such as Fe, As, Cr, Hg, Pb, and Cd, and a lower insoluble substance fraction (0.1% vs 0.4%), making it safe for potable water treatment applications.
QWhat types of wastewater is Solid PAC suitable for treating?
Solid PAC is highly adaptable and suitable for a wide range of water treatment 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 is 4–10, making it suitable for both acidic and alkaline water conditions.
QHow should Solid PAC be dissolved before use?
Solid PAC dissolves completely in just 3 minutes at room temperature. It requires a low dosing amount, leaves no residue, and significantly reduces the risk of equipment blockage. The concentration of the solution can be precisely controlled after dissolution, allowing for flexible dosing in various treatment systems.
QWhat are the packaging options and shelf life of Solid PAC?
Solid PAC is available in 25kg woven bags lined with inner plastic bags, or in 1-ton jumbo bags (customizable options are available). 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 in its unopened original packaging.
QCan the Al2O3 content and basicity of Solid PAC be customized?
Yes. Solid PAC offers high customizability. The Al2O3 content can be specified within the range of 28%–30%, and the basicity is adjustable from 40% to 90%. This flexibility allows the product to be tailored to meet specific water treatment requirements and process conditions for different industries.
