At NINGBO INNO PHARMCHEM CO.,LTD., we are passionate about the science that drives effective water treatment. A fundamental concept underpinning the efficacy of Poly Aluminium Chloride (PAC) is the process of flocculation. Understanding this mechanism is key to appreciating why PAC is such a powerful tool in achieving clear and safe water.

Water sources, whether for industrial use or public consumption, often contain microscopic suspended particles and dissolved impurities. These particles, such as clay, silt, organic matter, and microorganisms, are typically too small to settle out on their own and may carry electrical charges that keep them dispersed and stable in the water. This is where the role of a coagulant like PAC becomes indispensable.

The process begins with coagulation, where PAC is introduced into the water. PAC, being a highly charged cationic polymer, effectively neutralizes the negative charges present on the suspended particles. This charge neutralization destabilizes the particles, reducing the repulsive forces that keep them separated. As the particles lose their charge, they begin to attract each other.

Following coagulation is flocculation. In this stage, with gentle mixing, the destabilized particles collide and aggregate to form larger, visible clumps called flocs. PAC's molecular structure is designed to bridge these particles, creating larger, heavier, and more settleable aggregates. The efficiency of floc formation is critical; larger and denser flocs settle more rapidly and are more easily removed by subsequent physical processes like sedimentation or filtration.

The effectiveness of PAC in promoting flocculation is superior to many traditional coagulants. It creates robust flocs that are less prone to breaking apart during settling. This enhanced flocculation leads to a more efficient removal of impurities, including turbidity, color, and even some dissolved organic matter. The resulting water is significantly clearer, and the contaminants are concentrated into manageable sludge for disposal.

NINGBO INNO PHARMCHEM CO.,LTD. ensures that our Poly Aluminium Chloride products are optimized to facilitate this crucial flocculation process. By understanding the intricate interplay of charge neutralization and particle aggregation, we provide solutions that deliver exceptional water clarity and purity. Our expertise in water treatment chemicals means we can guide clients on optimal dosage and application to maximize the flocculation power of PAC for their specific needs.
