Poly Aluminum Chloride — PAC / CAS 1327-41-9

Description

1. Product Overview

Poly Aluminum Chloride (PAC) (CAS 1327-41-9) is a high-performance inorganic polymer coagulant widely used in water and wastewater treatment systems. It is engineered to deliver rapid floc formation and superior suspended solid removal across industrial, municipal, and process water applications. The product offers a high-efficiency alternative to traditional aluminum salts, reducing sludge volume while improving clarification performance. Strategically, PAC is a critical chemical in global water infrastructure due to tightening environmental discharge regulations and increasing demand for high-efficiency purification systems.

3. Core Industrial Applications

PAC is extensively used across water-intensive industries requiring high-efficiency clarification and contaminant removal.

• Municipal Water Treatment: Potable water clarification and turbidity reduction
• Industrial Wastewater Treatment: Heavy metal precipitation, COD/BOD reduction
• Paper & Pulp Industry: Retention aid and sizing agent improvement
• Textile Industry: Dye wastewater coagulation and color removal
• Oil & Gas: Produced water treatment and separation processes

PAC outperforms conventional coagulants such as aluminum sulfate due to faster reaction kinetics, wider pH adaptability, lower dosage requirements, and significantly reduced sludge generation—resulting in lower operational costs and improved process stability.
