🔬 Adaptability
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.

Frequently Asked Questions
What is Solid PAC and how does it differ from liquid PAC?
Solid PAC (Poly Aluminium Chloride) is a dry, powdered or granular form of the coagulant. Unlike liquid PAC, solid PAC offers easier long-distance transportation, a longer shelf life of up to 2 years, and allows users to control the concentration precisely after dissolution on-site.
What is the turbidity and COD removal efficiency of this Solid PAC?
This Solid PAC achieves a turbidity removal rate of ≥95% and a COD removal rate of ≥40%, making it highly effective for both drinking water purification and industrial wastewater treatment.
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. It is effective across a pH range of 4–10.
How quickly does Solid PAC dissolve, and what is the recommended dosage method?
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 — making it convenient for automated dosing systems.
What are the available packaging options and storage requirements?
Solid PAC is available in 25kg woven bags lined with plastic bags or 1-ton jumbo bags (customizable). It should be stored in a cool, dry place, protected from moisture and physical damage. The shelf life is 2 years for unopened packaging.
What is the difference between Industrial Grade and Drinking Water Grade Solid PAC?
Drinking Water Grade Solid PAC has stricter purity requirements — for example, 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 it is safe for use in potable water treatment applications.
