Advanced high-purity coagulants engineered to satisfy local US municipal and industrial effluent standards.
The water purification ecosystem in the United States faces intensifying regulatory pressures and shifting municipal infrastructure requirements. Across major industrial centers—from the oil and gas operations in Texas and the Permian Basin to the textile, pulp, and paper hubs in the Southeast—highly efficient inorganic macromolecular coagulants are replacing older chemical alternatives.
Historically, traditional Aluminum Sulfate (Alum) served as the primary coagulant. However, modern environmental engineering demands faster floc sedimentation rates and lower chemical dosing volumes to control total dissolved solids (TDS) and reduce secondary waste output. High-performance polyaluminum chloride (PAC) has stepped in as the industry benchmark, delivering effective turbidity removal even in low-temperature winter environments common in northern states.
Evaluate our range of high-efficiency water treatment agents to customize solutions for your industrial or municipal water demands.
Selecting the ideal polyaluminum chloride formulation requires assessing water parameters such as initial turbidity, biological load, and heavy metal concentrations. The chemical reactivity of PAC is determined by its active Al2O3 concentration and basicity (the ratio of hydroxyl groups to aluminum atoms). Standard municipal drinking water systems require a high-purity spray-dried powder containing 30% Al2O3 with low iron profiles to ensure standard compliance. For industrial wastewater treatment, polymeric compounds like Polymeric Aluminium Ferric Chloride (PAFC) provide rapid precipitation cycles by combining the advantages of iron and aluminum coagulants.
Contains up to 83% basicity. Exceptional for municipal potable water treatment. Delivers minimal pH depression, reducing overall post-treatment chemical costs.
Engineered with active iron molecules to accelerate floc sedimentation. Suited for treating high-chroma, high-turbidity industrial runoffs, oilfield waste, and steel mill sludge.
Integrating PAC with organic polymers like PDADMAC or Anionic/Cationic Polyacrylamide (PAM) results in micro-floc aggregation, speeding up heavy solids separation.

Procuring water treatment chemicals for the US market requires navigating strict regulatory frameworks. Under the Safe Drinking Water Act (SDWA), any chemical introduced into municipal purification plants must comply with NSF/ANSI Standard 60. This certification verifies that chemical impurities, such as heavy metals (Arsenic, Lead, Cadmium, Mercury), do not leach into public drinking water at concentrations exceeding designated Maximum Allowable Levels (MAL).
Wuxi BS Water Treatment maintains trace testing protocols for all export shipments. Our spray-dried PAC-01 formulation leverages high-purity raw materials, minimizing insoluble iron matrices. For chemical buyers in regions like California or New York, who manage strict regional environmental runoff guidelines, our low-dust dry solids and stable liquid products support predictable coagulation outcomes.
To maintain reliable material flows, we partner with key chemical distributors across the US, offering strategic warehousing near ports on both coasts. This structure mitigates supply chain delays, ensuring stable inventory levels of high-purity coagulants for municipal and industrial partners throughout the year.

PAC contains pre-polymerized aluminum ions, which exhibit higher charge densities than simple aluminum sulfate (Alum) molecules. This allows for faster micro-floc formation, higher settling velocities, and superior performance in low-temperature waters. Additionally, PAC consumes less water alkalinity, significantly reducing the requirement for auxiliary pH-adjusting chemicals.
Basicity represents the percentage of hydroxyl groups relative to aluminum atoms in the polymer structure. High-basicity PAC (70%-83%) contains a higher density of polymerized Al13 structures, which are efficient at neutralizing negative colloid charges in high-turbidity water. Low-basicity variants are suited for waters with low turbidity, where sweep coagulation mechanisms are required.
Liquid PAC is mildly acidic and should be stored in corrosion-resistant tanks constructed from materials like fiberglass-reinforced plastic (FRP), polyethylene (PE), or rubber-lined steel. Storage areas should remain between 32°F and 100°F (0°C to 38°C) to prevent crystallization or product degradation.
PAFC introduces iron (Fe) ions into the polymeric aluminum structure. The iron species form insoluble metal-phosphate complexes, enhancing phosphorus precipitation in secondary municipal clarify tanks, while the aluminum component aggregates organic particles.
