Poly Aluminum Chloride (PAC) is a chemical compound that has become indispensable in various treatment processes, most notably in water purification. At NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to providing high-quality PAC and educating our clients on its remarkable properties and the benefits it offers. This article provides a comprehensive look into what makes PAC such an effective and widely used chemical.

Chemically, Poly Aluminum Chloride is a polymeric aluminum salt with the general formula [Al2(OH)nCl(6-n)]m. The 'n' and 'm' represent variations in the polymer structure, which contribute to PAC's enhanced efficiency over simpler aluminum salts like aluminum sulfate. This polymeric structure means PAC molecules carry a higher positive charge, allowing them to neutralize a greater number of negatively charged impurities in water more effectively.

The mechanism by which PAC works in water treatment is primarily through coagulation and flocculation. When PAC is added to water, it rapidly hydrolyzes, forming positively charged polynuclear complexes. These complexes neutralize the negatively charged colloidal particles (like silt, clay, and organic matter) that cause turbidity and color. This process, known as coagulation, destabilizes the particles. Subsequently, these destabilized particles begin to collide and adhere to each other, forming larger, amorphous masses called flocs. This is the flocculation stage.

The advantages of using PAC over traditional coagulants are significant. Firstly, high purity poly aluminium chloride requires lower dosage rates to achieve the same level of water clarification, leading to cost savings for users. Secondly, PAC operates effectively over a broader pH range, offering greater flexibility in treatment conditions. Thirdly, the flocs formed by PAC are generally denser and settle more rapidly, improving the efficiency of sedimentation processes and reducing treatment time. When considering poly aluminum chloride price, these efficiencies often make it a more economical choice in the long run.

Furthermore, PAC produces less residual aluminum in treated water compared to aluminum sulfate, which is a critical consideration for drinking water applications. The availability of specific grades, such as poly aluminum chloride drinking water grade, ensures that it meets the strict safety and purity standards required for potable water. For industrial applications, industrial grade polyaluminium chloride offers robust performance in treating diverse wastewater streams, contributing to environmental protection.
