Transparent Water Treatment Coagulant Water Purification

Product Description:

Liquid Poly Aluminum Chloride (PAC) is widely utilized in water treatment and industrial applications as an inorganic polymer coagulant. Its chemical formula is typically denoted as [Al ₂ (OH) _n Cl _6-n ] _m , where n ranges from 1 to 5 and m is less than or equal to 10. This formulation results in a highly charged polymeric structure.

PAC is derived from the partial hydrolysis of aluminum chloride, which yields a solution containing abundant hydroxyl and aluminum ions. In comparison to conventional coagulants such as alum ( Aluminum Sulfate ), liquid PAC boasts enhanced efficiency, wider applicability, and eco-friendliness. Its liquid state negates the necessity for dissolution, facilitating quick mixing and immediate efficacy in treatment procedures.

Features:

Liquid PAC contains 10–12% Al ₂ O ₃ (aluminum oxide) with low impurities, ensuring consistent performance.

High Purity and Stability

Strong charge neutralization capability destabilizes suspended particles and colloids rapidly. Forms large, dense flocs that settle quickly, reducing turbidity and organic matter.

Effective across a broad pH range (5–9), minimizing the need for pH adjustment. Performs well in low-temperature or high-alkalinity water.

Less corrosive to equipment compared to ferric salts or sulfuric acid-based coagulants. Free of heavy metals and toxic byproducts, making it safe for drinking water applications.

Lower dosage requirements (20–50% less than traditional coagulants) reduce operational costs. Liquid form simplifies transportation, storage, and dosing systems.

Applications:

Water Treatment

Drinking Water Purification: Removes turbidity, algae, heavy metals, and microorganisms.

Wastewater Treatment: Treats industrial effluents (e.g., textiles, dyes, pharmaceuticals) by reducing COD, BOD, and phosphorus.

Municipal Sewage: Clarifies urban wastewater and aids sludge dewatering.

Industrial Processes

Papermaking: Acts as a retention agent and improves paper quality.

Textile Industry: Removes dyes and stabilizes wastewater pH.

Oil & Gas: Treats oil-containing wastewater and enhances oil-water separation.

Other Uses

Cosmetics: Functions as an antiperspirant ingredient.

Pharmaceuticals: Utilized in drug purification processes.

Agriculture: Adjusts soil pH and flocculates irrigation water.
