Polyaluminium Chloride (PAC) is an inorganic polymer widely used in drinking water purification processes. Known for its efficient coagulation and flocculation properties, PAC plays a crucial role in removing impurities from water, making it safe for consumption. This article explores the significance of Polyaluminium Chloride for drinking water treatment and its advantages over traditional coagulants.

How Polyaluminium Chloride Works

PAC functions by destabilizing suspended particles in water. When added to water, it hydrolyzes to form aluminum hydroxide, which binds with impurities such as sediments, organic matter, and microorganisms. This aggregation forms larger particles or "flocs," which can then be easily removed through sedimentation and filtration processes. The effectiveness of PAC makes it a preferred choice for water treatment facilities aiming to meet stringent safety standards.

Advantages of Using Polyaluminium Chloride

One of the key benefits of using Polyaluminium Chloride for drinking water is its high efficiency at lower doses compared to traditional coagulants like alum. This results in reduced chemical costs and less sludge generation, making the treatment process more economical and environmentally friendly. Additionally, PAC operates effectively across a wide pH range, ensuring consistent performance in various water qualities.

Enhancing Water Quality

Incorporating Polyaluminium Chloride in drinking water treatment significantly enhances water quality. It effectively removes turbidity, color, and harmful microorganisms, ensuring that the water is clear and safe for human consumption. The use of PAC also helps in reducing chlorine demand in subsequent disinfection processes, contributing to better overall water treatment efficiency.
