Effective wastewater treatment hinges on efficient contaminant removal, and at the heart of many successful processes lies the action of coagulants. Among these, Polyaluminum Chloride (PAC) has distinguished itself as a highly efficient inorganic polymer flocculant. Its mechanism of action is rooted in advanced chemical principles that promote rapid and effective aggregation of impurities, making it a cornerstone in industrial water treatment. As a leading manufacturer and supplier, understanding how PAC works is key to appreciating its value.

Polyaluminum Chloride functions through a dual mechanism: charge neutralization and sweep flocculation. When PAC is introduced into wastewater, the positively charged aluminum species (polymers) effectively neutralize the negative charges present on suspended particles and colloidal matter. This neutralization destabilizes the particles, allowing them to approach each other. Subsequently, these destabilized particles aggregate to form larger, visible flocs. This process is significantly accelerated by the higher molecular weight and polymeric structure of PAC compared to traditional single-metal coagulants like aluminum sulfate.

The 'sweep flocculation' aspect is equally important. As PAC hydrolyzes in water, it forms aluminum hydroxide precipitates. These precipitates act as a net, physically sweeping through the water and trapping suspended solids, dissolved organic matter, and even certain heavy metals. The rapid formation of dense alum flowers, a hallmark of PAC's performance, is a direct result of this efficient sweeping action. This leads to superior turbidity removal, often exceeding 95%, and a significant reduction in contaminants like COD and color. For industries seeking to buy Polyaluminum Chloride for enhanced treatment, this mechanism is crucial.

Moreover, PAC's efficiency is maintained across a wider range of pH and temperature conditions, making it a more adaptable and reliable choice for diverse industrial wastewater streams. Our commitment as a manufacturer in China is to provide PAC that consistently delivers these efficient coagulation properties. Whether you are treating paper mill effluent, textile wastewater, or municipal sewage, understanding how PAC works empowers you to optimize your treatment processes.
