Premium grade industrial chemicals engineered for rapid sedimentation, heavy organic removal, and high floc generation stability.
A Technical Whitepaper on Precision Dosing, Macromolecular Bridging, and Effluent Optimization by Wuxi BS Water Treatment Chemicals.
In modern industrial manufacturing and municipal effluent processing, the separation of suspended solids, colloidal particulate matters, and dissolved organic molecules is crucial. Industrial wastewater often contains highly charged, stable colloidal dispersions that resist natural gravity sedimentation. Understanding the chemical and thermodynamic mechanisms of coagulation and flocculation is essential to optimizing these separations and meeting stringent discharge standards.
Wuxi BS Water Treatment Chemicals Co., Ltd., with 27 years of research and industrial manufacturing experience, stands at the intersection of applied chemical engineering and supply chain scalability. By focusing on polycations such as Polyaluminum Chloride (PAC), Aluminum Chlorohydrate (ACH), and high molecular weight Polyacrylamide (PAM), we deliver tailored solutions that minimize chemical dosing and reduce sludge volume. Our advanced formulations neutralize negative surface charges on colloidal particles, destabilizing suspensions and enabling rapid aggregation into shear-resistant macro-flocs.
Charge Neutralization: Polyaluminum complexes ($Al_{13}$ and $Al_{30}$ polycations) adsorb onto negatively charged organic colloid surfaces, reducing zeta potential to zero and allowing attractive Van der Waals forces to aggregate the particles.
Polymer Bridging: Long-chain polyacrylamides (anionic or cationic) bind to multiple particles simultaneously, creating strong polymeric bridges that can withstand the high shear forces in modern dewatering equipment.
Sweep Coagulation: Rapidly precipitating amorphous aluminum hydroxide wraps around suspended solids, dragging them down to speed up sedimentation in high-turbidity systems.

Available in solid spray-dried powder and highly stable liquid forms. Active species include polymeric $Al_{13}$ and $Al_{30}$ structures, offering superior coagulating performance compared to traditional monomeric alum.
With a basicity exceeding 83%, ACH is the most concentrated liquid inorganic coagulant available. It provides high alumina content with minimal impact on treated water pH, significantly reducing post-treatment chemical usage.
Available as high molecular weight Anionic (APAM) and Cationic (CPAM) dry granules or emulsions. Tailored charge densities allow for efficient sludge thickening and cake dewatering across various municipal and industrial sludge types.
A highly cationic dicyandiamide-formaldehyde copolymer designed to decolorize high-color effluents, especially those from reactive, acid, and disperse dyeing processes in the textile industry.
A liquid cationic polymer with high charge density. Stable across a wide pH range, it acts as a primary coagulant and coagulation aid in water purification, industrial waste treatment, and paper mill drainage processes.

Our high molecular weight Cationic Polyacrylamide (CPAM) speeds up floc formulation and sludge dewatering. It is ideal for belt filter presses and centrifuges, reducing cake moisture content and sludge disposal costs.
Anionic Polyacrylamide (APAM) acts as a highly effective polymer flooding agent, improving sweep efficiency in enhanced oil recovery. Its high shear stability and thermal resistance ensure steady viscosity under demanding reservoir conditions.
Adding Polyaluminum Chloride (PAC) or low-molecular-weight organic coagulants before ultrafiltration or reverse osmosis removes colloidal foulants. This protects membranes, prevents organic fouling, and extends element life.
In paper mills, Polyacrylamide acts as a retention and drainage aid, improving fiber recovery and paper quality. It speeds up water drainage on wire sheets while reducing fiber loss in white water systems.
High-purity PAC and ACH remove trace metals and organic carbons with minimal residual aluminum. Our NSF/ANSI-60 certified formulations ensure municipal treatment plants meet clean drinking water standards.
Industrial textile effluents are highly colored and structurally complex. Our specialty Decoloring Agents capture and precipitate dye particles, clearing colored water to support internal recycling.
Driving sustainable, eco-friendly water treatment solutions through continuous polymer research.
As environmental regulations tighten worldwide, the water treatment industry is shifting toward greener, more sustainable chemical technologies. Wuxi BS Water Treatment Chemicals is at the forefront of this transition, developing next-generation formulations that balance high performance with environmental safety.
We are researching graft-copolymerized flocculants that combine natural starches and chitosans with synthetic monomers. These hybrid polymers offer high charge densities while decomposing naturally in soil systems, reducing environmental footprint.
Our R&D team is developing composite coagulants with built-in metal chelating groups. These formulations allow operators to precipitate mercury, cadmium, and lead in a single dosing step, eliminating the need for secondary treatment chemicals.
We supply polymers customized for real-time digital feed systems. These chemicals feature stable molecular distributions that respond predictably to automated control loops, helping plants prevent chemical overdosing.
