The efficacy of Polyaluminium Chloride (PAC) as a primary coagulant in water treatment is rooted in sophisticated chemical and physical mechanisms. Understanding these principles allows users to appreciate why NINGBO INNO PHARMCHEM CO., LTD.'s Polyaluminium Chloride PAC 30% is such a powerful inorganic polymer coagulant. This article explores the science behind PAC's performance, detailing how it achieves superior results in various water purification and wastewater treatment applications.

At its core, PAC functions by destabilizing suspended colloidal particles in water. These particles, such as clay, silt, and organic matter, typically carry a negative surface charge, causing them to repel each other and remain dispersed, thus contributing to turbidity. PAC, with its complex aluminum species and high positive charge, neutralizes these negative charges through a process called charge neutralization. This reduces the electrostatic repulsion between particles, allowing them to approach each other more closely.

Following charge neutralization, PAC facilitates flocculation through bridging mechanisms. The polymeric structure of PAC, with its hydroxyl groups and bridging aluminum atoms, can adsorb onto the surface of multiple destabilized particles. These adsorbed polymer chains then act as bridges, linking the particles together to form larger, more complex aggregates called flocs. This bridging action is significantly more effective than simple charge neutralization alone, leading to the rapid formation of large, dense, and easily settleable flocs. This characteristic is particularly valuable when dealing with high turbidity water, as our water treatment PAC powder is specifically formulated for this purpose.

The efficacy of Polyaluminium Chloride PAC 30% is also influenced by factors such as pH, temperature, and the nature of the contaminants. PAC typically operates effectively across a broad pH range, with optimal performance often observed in slightly acidic to neutral conditions. Its ability to form flocs quickly and its high activity make it an efficient industrial circulating water treatment agent, preventing scaling and improving water clarity. The science behind its application in industries like papermaking, textiles, and mining further highlights its versatility as a chemical auxiliary agent.
