High Purity Poly Aluminium Chloride (PAC-0Suppliers and Factory in China - Colorless Liquid, 10%-17% Active Content
Core Features
▶
High Effective Content: The content of Al₂O₃ is higher than 15%, and can reach up to 17% at most.
▶
Extremely Low Impurity Content: Compared to drinking water grade PAC, impurities are further reduced.
▶
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 (FAQ)
Q What is the Al₂O₃ content in your High Purity PAC, and why does it matter?
A Our High Purity PAC contains more than 15% Al₂O₃, with a maximum of 17%. A higher Al₂O₃ content means stronger coagulation performance, allowing smaller dosages to achieve effective water treatment results, which reduces overall operational costs.
Q Does liquid PAC need to be dissolved before use?
A No. One of the key advantages of our liquid PAC is that it can be directly added to the water treatment system without any pre-dissolution step. This saves labor costs and eliminates the need for dissolution equipment, making it more convenient and cost-effective.
Q What pH range is suitable for using this PAC product?
A Our PAC has a wide pH adaptability ranging from 4 to 10. This broad range makes it suitable for a variety of water sources and treatment conditions, while also exhibiting lower corrosivity to pipelines and equipment compared to high-concentration aluminum salts.
Q What types of wastewater can High Purity PAC treat?
A Our PAC is suitable for a wide range of applications including drinking water purification, municipal sewage treatment, industrial wastewater (papermaking, printing & dyeing, electroplating, chemical), coal slime water clarification, oilfield reinjection water, and stone cutting wastewater recycling.
Q How should High Purity Liquid PAC be stored, and what is its shelf life?
A The product should be stored in a cool, well-ventilated area away from direct sunlight. When kept sealed, the shelf life is 6 months. Available packaging options include 25L plastic drums, 1000L IBC totes, and liquid bags for flexible logistics.
Q How does liquid PAC compare to solid PAC in terms of flocculation speed?
A Liquid PAC molecules have higher activity, resulting in a flocculation speed approximately 20% faster than the solid version. This makes it particularly well-suited for small water treatment facilities or emergency treatment scenarios where rapid response is critical.
