Polyaluminium Chloride (PAC) is more than just a chemical; it's a sophisticated tool in the science of water purification. Understanding its operational mechanism is key to appreciating why it has become a preferred choice at NINGBO INNO PHARMCHEM CO.,LTD and across the global water treatment industry. PAC functions through a dual mechanism involving charge neutralization and sweep flocculation, making it exceptionally effective in removing a wide array of water impurities.

At the molecular level, PAC is a complex inorganic polymer composed of various aluminum species, including positively charged polynuclear cations such as Al13. When introduced into water containing negatively charged colloidal particles (like clay, silt, and organic matter), these positively charged aluminum species rapidly neutralize the destabilizing charges. This charge neutralization process, known as coagulation, breaks down the repulsive forces keeping particles dispersed, allowing them to begin aggregating.

Following coagulation, the process of flocculation takes place. The neutralized particles start to collide and bind together, forming larger aggregates known as flocs. PAC’s polymeric nature promotes the formation of larger, denser, and stronger flocs compared to simpler coagulants. This is often referred to as 'sweep flocculation,' where the polynuclear aluminum species physically enmesh and entrap impurities as they precipitate out of the solution.

The effectiveness of this 'poly aluminium chloride wastewater treatment' process is evident in its ability to remove not just suspended solids but also dissolved organic matter, color, and even certain heavy metals. The specific 'benefits of polyaluminium chloride in water' treatment stem from this efficient floc formation, which leads to faster settling times and improved efficiency in subsequent filtration steps. This is why it's considered a 'high efficiency coagulant for industrial water' and municipal supplies alike.
