Product Description

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 (FAQ)

What are the primary advantages of using this Polyaluminum Chloride (PAC)?

Our PAC features a large molecular structure with high-efficiency water purification capabilities. It provides rapid floc formation, fast sedimentation, and strong adsorption. It achieves a turbidity removal rate of ≥95% and a COD removal rate of ≥40%.

What is the difference between Industrial Grade and Drinking Water Grade PAC?

Drinking Water Grade PAC has a higher Al₂O₃ content (≥29.0%) and a much lower mass fraction of insoluble substances (≤0.1%). It also strictly limits heavy metals, such as Lead (Pb ≤0.0005%) and Arsenic (As ≤0.0001%), to ensure safety for consumption.

How adaptable is this product to different pH levels and water qualities?

It offers strong adaptability across a wide pH range of 4 to 10 and is highly resistant to high turbidity and salinity, making it perfect for challenging wastewater from chemical, paper-making, and printing/dyeing processes.

How long does it take for the solid PAC to dissolve?

The solid PAC completely dissolves in room temperature water within just 3 minutes, leaving zero residue. This quick dissolution prevents equipment blockage and ensures optimal dosing efficiency.

What are the recommended packaging and storage conditions?

The product is supplied in 25kg woven bags with plastic lining or 1-ton jumbo bags. It should be stored in a cool, dry place protected from moisture. Under these conditions, the unopened shelf life is up to 2 years.
