Polyaluminum chloride

Its efficient action over a wide pH range makes it an ideal solution for municipal, industrial, and potable water applications requiring reliable and cost-effective clarification. Polyaluminum Chloride is available in both liquid and powder forms with different Al₂O₃ contents and basicity levels to meet diverse operational needs. Typical Al₂O₃ percentages range from 8%–12% for liquid PAC and 10%–18% for powder grades, with basicity commonly between 40% and 70%. Powder PAC usually appears yellow to orange, while high-purity grades may be light yellow or white. PAC is composed of polymerized aluminum species, chloride ions, and controlled amounts of hydroxyl groups, providing excellent charge neutralization and bridging ability. Its main applications include drinking water treatment, wastewater and sewage treatment, industrial effluent clarification, paper and pulp processing, textile wastewater treatment, and food-processing wash water systems.

Polyaluminum Chloride is supplied in a variety of commercial packages such as 25 kg and 50 kg bags, jumbo bags (500–1000 kg), plastic drums, IBC tanks, and bulk tanker deliveries for liquid grades. Special specifications including low-iron, high-basicity, and potable-water-approved grades are available upon request. With advantages such as lower dosage requirements, reduced sludge generation, minimal pH impact, and excellent storage stability, PAC remains a preferred coagulant for industries seeking efficient, compliant, and high-quality water treatment solutions.
