Poly Aluminium Chloride (PAC) is a cornerstone of modern water treatment, renowned for its exceptional ability to purify water. Understanding the science behind its efficacy is key to appreciating its value as an efficient water purification chemical. NINGBO INNO PHARMCHEM CO.,LTD., a trusted supplier in China, provides PAC that leverages these scientific principles to deliver pristine water quality.

The primary mechanism by which PAC functions is through coagulation and flocculation. In raw water, impurities like suspended solids, colloids, and dissolved organic matter often carry negative electrical charges. These charges repel each other, keeping the particles dispersed and preventing them from settling. PAC, being a positively charged polymer, neutralizes these negative charges. This charge neutralization allows the particles to approach each other, initiating the formation of smaller aggregates. This initial stage is known as coagulation.

Following coagulation, the process of flocculation takes over. PAC molecules, with their extensive polymeric chains, act as bridges, linking the destabilized colloidal particles together. This bridging action creates larger, heavier, and more amorphous structures called flocs. The size and density of these flocs are crucial for their subsequent removal. PAC is particularly effective at forming large, robust flocs that settle rapidly in sedimentation tanks or are easily captured by filters. This enhanced settling characteristic is a significant advantage, particularly when considering poly aluminium chloride for drinking water treatment, as it ensures efficient removal of contaminants.

The advantages of PAC over traditional coagulants are scientifically validated. Its higher charge density and polymeric structure allow for more efficient charge neutralization and bridging, often requiring lower dosages. This results in less residual aluminum in the treated water and a significant reduction in sludge volume, making it an effective wastewater treatment solution and an environmentally sound choice. As an industrial water treatment coagulant, its predictable performance and adaptability to various water conditions underscore its scientific superiority. NINGBO INNO PHARMCHEM CO.,LTD. ensures that the PAC supplied embodies these scientific principles, providing a reliable chemical for all your water treatment needs.
