The effectiveness of Polyaluminum Chloride (PAC) as a water and sewage treatment agent stems from its unique chemical structure and mechanism as a flocculant. Unlike traditional coagulants, PAC is an inorganic polymer characterized by its high charge density and polymeric bridging capabilities. NINGBO INNO PHARMCHEM CO.,LTD., a premier supplier in China, provides PAC that exemplifies these powerful flocculation properties.

The primary function of PAC as a flocculant is to destabilize suspended particles in water. These particles, such as clay, silt, and organic matter, typically carry negative surface charges, causing them to repel each other and remain dispersed. PAC, with its positively charged aluminum species, neutralizes these negative charges through a process called charge neutralization. This reduces the repulsive forces between particles, allowing them to approach each other closely.

Following charge neutralization, PAC promotes flocculation through two main mechanisms: sweep flocculation and bridging. In sweep flocculation, the aluminum hydroxide precipitate formed when PAC is added to water entraps suspended particles as it settles. Bridging occurs when the long polymer chains of PAC adsorb onto multiple particles, physically linking them together. This process creates larger, denser flocs that are easily removed by sedimentation, filtration, or flotation. Understanding these principles is key when considering high purity PAC supplier China options for optimal treatment results.

The superior performance of PAC as a flocculant for sewage treatment and general water purification is attributed to its higher basicity and the presence of polymerized aluminum species, which offer more effective charge neutralization and bridging compared to monomeric aluminum salts. This leads to faster settling rates, better dewatering of sludge, and a wider effective pH range for treatment. NINGBO INNO PHARMCHEM CO.,LTD. ensures that its PAC products possess these desirable characteristics, making them ideal for various applications.
