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) reduction 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 Poly Aluminium Chloride (PAC)?
Our high-purity PAC (Liquid Type 1) contains a minimum of 15% Al₂O₃, with the content reaching up to 17% at its highest. This high alumina content ensures superior flocculation performance compared to standard-grade PAC products.
Q
What is the difference between Liquid Type 1 and Liquid Type 2?
The main difference lies in density and Al₂O₃ content. Type 1 has a density ≥ 1.30 g/cm³ and Al₂O₃ ≥ 15.0%, making it a higher-concentration option. Type 2 has a density of 1.15 g/cm³ and Al₂O₃ ≥ 10.0%, suitable for applications requiring a more diluted solution. Both types share the same basicity range (40–55%) and pH range (3.5–5.0).
Q
Does liquid PAC need to be dissolved before use?
No. One of the key advantages of our liquid PAC is that it does not require any pre-dissolution. It can be directly dosed into the water treatment system, which significantly saves labor costs and eliminates the need for dissolution equipment, making operations more efficient.
Q
What types of wastewater is this PAC suitable for treating?
Our PAC is highly versatile and suitable for a wide range of applications, including drinking water purification (groundwater and surface water), municipal sewage treatment, industrial wastewater (papermaking, printing and dyeing, electroplating, chemical), as well as specialized uses such as coal preparation plant water clarification, oilfield reinjection water treatment, and stone cutting wastewater recycling.
Q
How should liquid PAC be stored, and what is its shelf life?
Liquid PAC should be stored in a cool, well-ventilated area away from direct sunlight. When kept in a sealed container, the shelf life is 6 months. Available packaging options include 25L plastic drums, 1000L IBC totes, and liquid bags to suit different storage and transportation needs.
Q
Is liquid PAC corrosive to pipes and equipment?
Our liquid PAC features wide pH adaptability ranging from 4 to 10, and exhibits lower corrosivity to pipelines and equipment compared to high-concentration aluminum salts. This makes it a safer and more equipment-friendly choice for long-term use in water treatment systems, reducing maintenance costs and extending equipment lifespan.
