The effectiveness of Polyaluminum Chloride (PAC) in sewage treatment is rooted in sophisticated chemical mechanisms that facilitate the removal of a wide array of contaminants. For procurement managers and wastewater engineers seeking to optimize their treatment processes, understanding these principles is key to making informed purchasing decisions. As a leading PAC manufacturer, we are dedicated to providing clarity on how our products deliver superior performance.

At its core, PAC functions as a coagulant and flocculant. In aqueous solutions, PAC hydrolyzes to form positively charged polynuclear complexes, such as [Al2(OH)nCl6-n]m+. These positively charged species effectively neutralize the negatively charged colloidal particles present in sewage, such as organic matter, suspended solids, and certain dissolved pollutants. This charge neutralization process is the initial step, destabilizing the colloidal suspension and preventing them from remaining dispersed.

Following charge neutralization, the polynuclear complexes undergo further hydrolysis and polymerization, forming larger polymeric aluminum hydroxide species. These species act as bridging agents, binding destabilized particles together into larger, amorphous aggregates known as flocs. The efficiency of floc formation is heavily influenced by factors like pH, temperature, and the dosage of PAC. Our yellow Polyaluminum Chloride, with its specific basicity and Al2O3 content, is formulated to promote rapid and robust floc development, essential for effective sewage treatment.

The resulting flocs are typically larger, denser, and more easily settled than those formed by traditional coagulants like aluminum sulfate. This improved settling characteristic leads to clearer supernatant water and reduced solid waste volume, both significant advantages in wastewater management. When you buy Polyaluminum Chloride from our facility, you are investing in a product engineered for optimal flocculation and settling performance, contributing to higher treatment efficiency and lower operational costs.
