Ensuring the safety and purity of drinking water is a fundamental public health responsibility. The processes involved in municipal water treatment rely on effective coagulants to remove harmful contaminants. Among the most efficient chemicals utilized today is Polyaluminium Chloride (PAC). As a leading supplier of high-quality water treatment chemicals, we delve into the science behind PAC's efficacy in delivering clean, safe drinking water.

Polyaluminium Chloride, an inorganic polymer coagulant, is widely recognized for its superior performance in water purification. Its chemical structure and properties allow it to neutralize the negative charges of suspended particles and dissolved organic matter in raw water. This process, known as coagulation, destabilizes the contaminants, causing them to clump together into larger, heavier masses called flocs. The formula [Al2(OH)nCl6-n]m accurately represents the polymeric nature that contributes to its effectiveness.

The mechanism by which PAC purifies water is multifaceted. Its high charge density enables extensive charge neutralization of colloidal particles, while its polymeric chains can bridge between these particles, forming larger, more manageable flocs. This enhanced flocculation leads to faster settling rates in sedimentation tanks and improved removal efficiency during filtration. Unlike some traditional coagulants, PAC typically exhibits minimal impact on the water's pH, reducing the need for secondary pH adjustment chemicals, which further simplifies the treatment process and lowers operating costs.

For municipalities and water authorities, sourcing PAC from a reliable manufacturer is essential. Consistency in product parameters such as Aluminium Oxide (Al2O3) content and basicity ensures predictable performance and compliance with drinking water standards. By choosing a trusted PAC supplier, you guarantee the delivery of a chemical that effectively removes turbidity, color, and potentially harmful microorganisms, while minimizing residual aluminium levels. Investing in high-quality PAC is investing in public health and the efficiency of your water treatment infrastructure.
