PolyAluminium Chloride (PAC) Liquid - 10%-15% Active Ingredient | China Suppliers & Factory
Core Features
✔
Convenient to Use: No need for dissolution, can be directly added, saving labor and dissolution equipment costs.
⚡
Quick Response: Liquid molecules have high activity, and the flocculation speed is 20% faster than that of the solid version, making it particularly suitable for small water treatment facilities or emergency scenarios.
🛡
Low Corrosivity: Wide pH adaptability (4–10), with lower corrosivity to pipelines/equipment than high-concentration aluminum salts.

🏙 Municipal Sewage
Coagulation sedimentation, sludge dewatering, BOD (biochemical oxygen demand) in urban domestic sewage treatment plants.
🏭 Industrial Wastewater
Treatment of papermaking black liquor, decolorization of printing and dyeing wastewater, removal of heavy metals from electroplating wastewater (Cr⁶⁺, Cu²⁺), and removal of phosphorus from chemical wastewater.
🔧 Other Scenarios
Coal slime water clarification in coal preparation plants, oil removal from oilfield reinjection water, and recycling of stone cutting wastewater.
Frequently Asked Questions
Q
What is Liquid PAC and how does it differ from solid PAC?
Liquid PAC (Poly Aluminum Chloride) is a ready-to-use aqueous solution of aluminum chlorohydrate. Unlike solid PAC, it requires no dissolution step before dosing, which saves labor costs and eliminates the need for dissolution equipment. Liquid PAC also offers 20% faster flocculation speed due to the higher molecular activity of its liquid form.
Q
What is the Al₂O₃ content difference between Industrial Grade and Drinking Water Grade?
Industrial Grade Liquid PAC contains a minimum of 8.0% Al₂O₃, while Drinking Water Grade contains a minimum of 10.0% Al₂O₃. The Drinking Water Grade also has significantly stricter limits on heavy metals such as Fe (≤0.2%), As (≤0.0001%), Cr (≤0.0005%), and other trace contaminants to ensure safety for potable water applications.
Q
What pH range is Liquid PAC suitable for?
Liquid PAC has a wide pH adaptability ranging from 4 to 10, making it suitable for a broad range of water treatment conditions. This wide adaptability also means it has lower corrosivity to pipelines and equipment compared to high-concentration aluminum salts, reducing maintenance costs.
Q
What packaging options are available for Liquid PAC, and how should it be stored?
Liquid PAC is available in 25L plastic drums, 1000L IBC totes, and liquid bags for bulk container shipments. It should be stored in a cool, well-ventilated area away from direct sunlight. When kept sealed, the shelf life is 6 months.
Q
Can Liquid PAC be used for drinking water treatment?
Yes. Our Drinking Water Grade Liquid PAC meets international drinking water standards. It is effective for removing iron and manganese from groundwater, reducing turbidity in surface water, and supporting coagulation processes in municipal water treatment plants. All heavy metal content levels comply with the strictest safety thresholds for potable water use.
Q
What types of industrial wastewater can Liquid PAC treat?
Liquid PAC is highly versatile for industrial wastewater treatment. It is effective for treating papermaking black liquor (delignification, COD reduction), decolorizing printing and dyeing wastewater (reactive dyes, sulfur dyes), removing heavy metals from electroplating wastewater (Cr⁶⁺, Cu²⁺), removing phosphorus from chemical wastewater, clarifying coal slime water in coal preparation plants, removing oil from oilfield reinjection water, and recycling stone cutting wastewater.
