Polyaluminum Chloride (PAC) has become a cornerstone in modern water treatment due to its scientifically proven efficacy as a coagulant. Understanding the underlying mechanisms of PAC action is crucial for R&D scientists and environmental engineers seeking to optimize water purification processes. As a dedicated manufacturer and supplier, we leverage deep scientific understanding to produce PAC that consistently delivers superior results.

The effectiveness of PAC in water treatment is rooted in its ability to destabilize colloidal particles and promote their aggregation into larger flocs. Unlike simpler coagulants, PAC is a pre-polymerized inorganic salt containing aluminum species with higher positive charges and greater molecular weight. When introduced into water, these polymeric species neutralize the negative surface charges of suspended particles and dissolved organic matter, a process known as charge neutralization. Simultaneously, the long polymeric chains of PAC can bridge between multiple destabilized particles, forming larger, amorphous structures – the flocs.

The formation of these flocs is critical for efficient contaminant removal. PAC-induced flocs are typically denser and settle more rapidly than those formed by traditional coagulants like aluminum sulfate. This enhanced settling rate improves the efficiency of sedimentation and filtration stages in water treatment plants. For professionals looking to buy Polyaluminum Chloride for its proven scientific advantages, selecting a product with controlled polymerization and basicity is key. As a leading PAC supplier in China, we ensure our products are manufactured with precise control over these parameters, guaranteeing optimal coagulation performance. Explore how the science behind PAC can elevate your water treatment strategies and ensure the production of cleaner, safer water.
