Polyaluminum chloride (PAC), identified by CAS number 1327-41-9, is a versatile inorganic polymer widely used across multiple industries as a coagulant and flocculant. This chemical compound plays a crucial role in various industrial processes due to its ability to remove impurities from water and other solutions. Its effectiveness stems from its chemical structure that allows it to neutralize negatively charged particles, causing them to coagulate for easy removal. This blog explores the industries that rely on CAS 1327-41-9 and examines its applications within each sector.

What Makes CAS 1327-41-9 Essential for Water Treatment Processes?

How Does PAC (CAS 1327-41-9) Function in Municipal Water Treatment?

Polyaluminum chloride (CAS 1327-41-9) serves as a primary coagulant in municipal water treatment facilities worldwide. When introduced to raw water sources, PAC neutralizes the negative charges of suspended particles such as clay, silt, organic matter, and microorganisms. This neutralization process causes these particles to clump together, forming larger flocs that can be easily removed through sedimentation and filtration processes. The effectiveness of CAS 1327-41-9 is particularly notable because it performs well across a wide pH range (5.0-8.0) and in varying water temperatures. Unlike traditional aluminum sulfate (alum), PAC maintains its efficiency even in colder water conditions. Additionally, CAS 1327-41-9 produces less sludge than alternative coagulants, reducing disposal costs and environmental impact for water utilities.
