PolyAluminium Chloride (PAC) Liquid – High-Quality China Suppliers & Factory, 10%-15% Active Ingredient
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.

Applicable Scenarios
Our PAC has been widely used in industrial and municipal water treatment scenarios worldwide, with typical cases including:
💧
Drinking water purification: Removal of iron and manganese from groundwater, turbidity removal from surface water, meeting international drinking water standards.
🏙️
Municipal sewage: Coagulation sedimentation, sludge dewatering, BOD (biochemical oxygen demand) in urban domestic sewage treatment plants.
🏭
Industrial wastewater: Treatment of papermaking black liquor (delignification, reduction of COD), decolorization of printing and dyeing wastewater (removal of reactive dyes, sulfur dyes), 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 chloride polymer. Unlike solid PAC, it does not require dissolution before use, which saves time, labor, and equipment costs. It also offers 20% faster flocculation speed due to the high activity of liquid molecules.
Q
What is the Al₂O₃ content in industrial grade vs. drinking water grade liquid PAC?
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 much stricter limits on heavy metal impurities such as Fe, As, Cr, Hg, Pb, and Cd to ensure safety for potable water treatment.
Q
What pH range is liquid PAC effective in?
Liquid PAC has a wide pH adaptability ranging from 4 to 10, making it suitable for a broad range of water treatment applications. Its lower corrosivity compared to high-concentration aluminum salts also makes it safer for use with pipelines and equipment.
Q
What types of wastewater can liquid PAC treat?
Liquid PAC is highly versatile and can be used to treat drinking water (iron/manganese removal, turbidity reduction), municipal sewage (coagulation sedimentation, sludge dewatering), industrial wastewater (papermaking, printing/dyeing, electroplating, chemical), as well as specialized applications such as coal slime water, oilfield reinjection water, and stone cutting wastewater.
Q
How should liquid PAC be packaged and stored?
Liquid PAC is available in 25L plastic drums, 1000L IBC totes, and liquid bags for flexible logistics options. It should be stored in a cool, well-ventilated location away from direct sunlight. When kept sealed, the shelf life is 6 months.
Q
Is liquid PAC suitable for emergency water treatment scenarios?
Yes. Because liquid PAC requires no pre-dissolution and reacts 20% faster than solid PAC, it is particularly well-suited for small water treatment facilities and emergency scenarios where rapid deployment and quick flocculation response are critical.
