At NINGBO INNO PHARMCHEM CO.,LTD., we believe in empowering our clients with knowledge about the products they use. Polyaluminium Chloride (PAC) is a sophisticated chemical agent, and understanding its scientific action is key to appreciating its efficacy in water purification.

The primary mechanism by which PAC purifies water is through coagulation and flocculation. Unlike simple salts, PAC is a polymer composed of various aluminum species with high positive charges. This characteristic allows it to effectively neutralize the negative charges present on suspended particles, colloids, and dissolved organic matter in water. This process, known as charge neutralization, destabilizes the particles, preventing them from repelling each other.

Following charge neutralization, PAC also operates through adsorption bridging. The long polymer chains of PAC can adsorb onto the surface of destabilized particles, effectively linking them together. This creates larger, more manageable aggregates, often referred to as micro-flocs. The high molecular weight and the multiple positive charges on the PAC molecule facilitate this bridging action.

When introduced into the water, PAC hydrolyzes, forming aluminum hydroxide precipitates. These precipitates have a large surface area and a strong adsorption capacity, further attracting and trapping impurities. This process, known as sweep flocculation, effectively sweeps out suspended solids, colorants, and certain dissolved contaminants from the water column.

The outcome of these combined actions is the formation of visible flocs – clumps of aggregated impurities. These flocs are significantly heavier and larger than the original suspended particles, making them readily settleable through sedimentation or easily removable via filtration. The efficiency of polyaluminium chloride water treatment lies in its ability to rapidly accelerate these natural processes.

NINGBO INNO PHARMCHEM CO.,LTD. supplies polyaluminium chloride that is manufactured to optimize these scientific principles. Our high efficiency coagulant PAC ensures that these mechanisms are activated efficiently, leading to superior water quality. Whether you are researching the polyaluminium chloride powder price or looking for the best polyaluminium chloride supplier, understanding the science behind PAC highlights its value.

By leveraging the advanced chemistry of PAC, water treatment facilities can achieve cleaner water with fewer resources, demonstrating the power of applied chemical science in environmental protection.
