Poly Aluminum Chloride (commonly known as PAC) is a highly efficient inorganic polymer coagulant. Synthetic variations, characterized by their high molecular weight and ionic charge, make it a dominant chemical agent in separating colloidal particles and suspended matter from raw water matrices. Unlike traditional alum (aluminum sulfate), PAC undergoes rapid hydrolysis, ensuring the formation of heavy, fast-settling flocs even at extremely low water temperatures.
The general formula for PAC is represented as [Al2(OH)nCl6-n]m. The performance and efficiency of PAC are largely dictated by its basicity value—the degree of hydroxyl substitution. Industrial grade PAC typically ranges between 50% to 85% basicity. Higher basicity translates to fewer acidic residues post-treatment, safeguarding downstream piping systems against corrosion, while drastically minimizing the consumption of alkaline neutralizing agents.

Founded in 1998, Wuxi BS Water Treatment Chemicals Co., Ltd. has established itself as an international benchmark for research, development, and high-volume synthesis of municipal and industrial water treatment agents. Spanning nearly three decades, we have continuously advanced our production lines, introducing intelligent solid feeding equipment and automated continuous-process liquid formulation reactors in 2025.
Our strategic location in Wuxi, China allows us to seamlessly tap into localized high-quality bauxite deposits and raw acid materials, which reduces operating overheads and translates to unparalleled economic viability for our global trade partners. We hold a comprehensive suite of international approvals, proving our strict adherence to both environmental sustainability and industrial safety benchmarks.
We manufacture a broad matrix of water treatment solutions tailored to specific turbidity levels, pH restrictions, and settling velocities.
From municipal drinking systems to harsh petrochemical processing, PAC adapts seamlessly to distinct operational environments.
PAC plays a pivotal role in municipal and industrial wastewater clarifiers. Its positive electrostatic charge destabilizes negatively charged colloidal particles, precipitating suspended organics, heavy metals, and phosphates, ensuring discharge limits meet strict ecological parameters.
Used extensively in oil-water separation systems, petroleum refineries, and drilling fluid clarification processes. Solid and liquid PAC variants break down emulsion barriers, accelerating the precipitation of drilling muds and oily sludges during upstream oilfield extraction.
By coagulating micro-turbidity particles prior to microfiltration (MF) or reverse osmosis (RO) systems, PAC prevents early membrane fouling. This optimization prolongs the system lifetime and cuts overall operational costs for desalinization plants.
PAC is a key agent in paper sizing, retention, and drainage. It promotes the precipitation of rosin size onto cellulose fibers, enhances paper strength, and filters out fine fibers from white water loops to implement closed-loop wastewater recycling.
Highly purified, low-iron spray-dried PAC is the gold standard for producing potable drinking water. It safely removes suspended particulate matter, microscopic pathogens, and natural organic matter (NOM) while minimizing residual aluminum levels.
