The effectiveness of water treatment hinges on efficient coagulation and flocculation processes. Polyaluminium Chloride (PAC) has revolutionized these processes with its advanced chemical properties, offering superior performance in water clarification. As a leading supplier of high-quality PAC, NINGBO INNO PHARMCHEM CO.,LTD. is pleased to share insights into the science that makes PAC such a powerful tool for water treatment professionals.

At its core, PAC is an inorganic polymer with a high positive charge density. When introduced into water containing negatively charged suspended particles, colloids, and organic impurities, the PAC molecules act as charge neutralizers. This neutralization destabilizes the particles, allowing them to collide and aggregate. Simultaneously, the extended polymer chains of PAC can bridge between these destabilized particles, forming larger, amorphous masses known as flocs. This process is significantly more efficient than that achieved by simple inorganic salts like aluminum sulfate.

The key advantage of PAC lies in its hydrolysis behavior. Unlike aluminum sulfate, which requires specific pH conditions to form effective flocs, PAC is effective over a broader pH range. Its higher basicity means it contains more polymeric aluminum species, which are inherently more effective at bridging and entrapping impurities. This leads to faster settling rates and denser flocs, simplifying the subsequent separation steps in filtration and sedimentation. For purchasing professionals, this translates to reduced treatment times and more efficient plant operations.

Furthermore, PAC produces significantly less sludge compared to traditional coagulants. This reduction in residual waste minimizes disposal costs and environmental impact. When you buy PAC from a reputable manufacturer like us, you are investing in a scientifically advanced solution that offers both performance and sustainability. Understanding these scientific principles empowers procurement managers and R&D scientists to make informed decisions about chemical selection. We are readily available to provide quotes and samples to demonstrate the superior science behind our PAC products.
