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.
