PolyAluminium Chloride (PAC) Liquid - China Suppliers & Factory - 10%-15% Active Ingredient, Transparent Liquid
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 (FAQ)
Q What is Liquid PAC and how does it differ from solid PAC?
A Liquid PAC (Poly Aluminum Chloride) is a ready-to-use solution that requires no dissolution before dosing. Compared to solid PAC, it offers 20% faster flocculation speed due to higher molecular activity, reduces labor costs, and eliminates the need for dissolution equipment, making it ideal for continuous or emergency water treatment operations.
Q What is the Al₂O₃ content difference between Industrial Grade and Drinking Water Grade?
A 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, As, Cr, Hg, Pb, and Cd to ensure safety for potable water treatment.
Q What is the suitable pH range for using Liquid PAC?
A Liquid PAC has a wide pH adaptability ranging from 4 to 10. This broad range makes it compatible with a variety of water sources and treatment processes, while maintaining lower corrosivity to pipelines and equipment compared to high-concentration aluminum salts.
Q What packaging options are available and what is the shelf life?
A Liquid PAC is available in 25L plastic drums, 1000L IBC totes, and liquid bags for bulk container shipments. When stored sealed in a cool, well-ventilated place away from direct sunlight, the shelf life is 6 months.
Q Can Liquid PAC be used for industrial wastewater treatment?
A Yes. Liquid PAC is widely applied in industrial wastewater treatment, including papermaking black liquor treatment (delignification and COD reduction), decolorization of printing and dyeing wastewater, removal of heavy metals (Cr⁶⁺, Cu²⁺) from electroplating wastewater, and phosphorus removal from chemical wastewater.
Q Is Liquid PAC suitable for drinking water purification?
A Yes. The Drinking Water Grade Liquid PAC meets international drinking water safety standards and is effective for removing iron and manganese from groundwater and reducing turbidity from surface water. Its heavy metal content is strictly controlled to ensure it is safe for use in potable water treatment systems.
