Founded in 1998, Wuxi BS Water Treatment Chemicals Co., Ltd. (originally renamed in 2005 as Wuxi Bisheng Water Treatment Agent Co., Ltd.) stands at the absolute vanguard of industrial macromolecular synthesis and clean-water technology in China. Over nearly three decades of targeted research and empirical development, we have established ourselves as a premier manufacturing base and global technical authority for a comprehensive suite of water treatment polymers.
Operating from our highly automated production facilities, we produce advanced chemical formulations designed for municipal sewage treatment, complex industrial wastewater remediation, drinking water purification, and specialized oilfield recovery operations. By integrating our deep chemistry experience with robust supply chains, Wuxi BS supports water-stressed regions worldwide, facilitating compliance with the most rigorous environmental standards.
Our technical value proposition hinges on precision polymer design—adjusting molecular weight, charge density, and ionic properties to deliver highly optimized destabilization and flocculation kinetics. Under leadership that merges traditional expertise with modern industrial AI tools, Wuxi BS has evolved from a local chemical pioneer into a globally synchronized enterprise.
With regions enforcing ultra-low trace element thresholds (such as lead, arsenic, and monomer residues), global operators prioritize suppliers with certified clean-process chemistry. Wuxi BS compounds align with EU REACH, FDA standards for indirect contact, and international heavy-metal limits.
Industrial operators cannot risk operational downtime due to raw chemical shortages. With a finished-product warehouse of over 20,000 tons, Wuxi BS buffers procurement challenges against international transport delays and seasonal volume surges.
Advanced coagulants like Aluminum Chlorohydrate (ACH) and high-purity Polyaluminum Chloride (PAC-01) reduce the overall volume of chemical sludge generated during neutralization, addressing both carbon footprints and hazardous disposal costs.
Available in high-purity liquid formats (10%-17% active ingredient) and high-quality solid powders/granules. Wuxi BS Polyaluminum Chloride possesses optimized basicity to ensure rapid hydrolysis, high charge neutralization capacity, and minimum pH depressant impact. Our Composite Polyaluminum Chloride (CPAC) exhibits enhanced cross-linking to target complex industrial colloids.
Formulated for extreme basicity (typically >83%) and exceptionally high Al2O3 content (up to 23% in liquid, 46% in powder). ACH acts as an ultra-concentrated inorganic coagulant. It is highly effective in drinking water treatment and papermaking, requiring lower dosage volumes while drastically minimizing post-treatment sludge accumulation.
High molecular weight linear polymers. Cationic Polyacrylamide (CPAM) targets negatively charged organic matrices common in biological sludge, enabling efficient belt-filter press or centrifuge dewatering. Anionic Polyacrylamide (APAM) features high molecular chain length to facilitate massive aggregate bridge-flocculation in mineral processing and metallurgy.
A highly cationic dicyandiamide-formaldehyde copolymer engineered specifically for dye-house effluents, pulp mill discharges, and heavily colored textile wastewater. WDA exhibits exceptional capacity to cleave chromophore bonds in soluble acid, reactive, and disperse dyes, binding them into easily sedimentable macro-flocs.
Biological municipal plants yield massive amounts of secondary activated sludge. Applying Wuxi BS Cationic Polyacrylamide (CPAM) at targeted dosage levels results in robust floc density, superior water release, and high cake solids percentage. Our polymers maintain flock stability even under high shear stresses in dynamic centrifuge dewatering systems.
In downstream refinery wastewater processing and upstream polymer flooding operations, oil-in-water emulsions present major operational challenges. Our specialized Poly(diallyldimethylammonium chloride) (PDADMAC) acts as a highly effective demulsifier and organic coagulant, breaking down complex hydrocarbon-surfactant networks to ensure clean effluent discharges.
Reverse Osmosis (RO) and Ultrafiltration (UF) systems are highly vulnerable to particulate and organic fouling. Implementing low-dose inorganic coagulants like Aluminum Chlorohydrate (ACH) removes dissolved organic carbon (DOC) and colloidal silica prior to filtration, extending membrane operational lifespan and reducing backwash frequencies.
To run high-speed papermaking lines, paper mills must rapidly drain water while retaining fine fibers and inorganic fillers. Our cationic polymers and specialty Polymeric Aluminium Ferric Chloride (PAFC) serve as effective retention and drainage aids, improving sheet formation, opacity, and overall production capacity.
Wuxi BS Water Treatment offers comprehensive OEM/ODM customization services. Water treatment needs vary depending on salinity, temperature, and contaminant profiles. Our lab engineers formulate chemicals to meet target viscosity, active ingredient levels, and raw material purity specifications.
Launched advanced digital intelligent solid feeding systems in 2025. These setups continuously measure effluent parameters and auto-adjust dry powder chemical feeding. This prevents under-dosing or over-dosing, which can lead to chemical wastage and secondary environmental pollution.
Transitioning raw materials toward carbon-neutral precursors. We are optimizing our polymerization lines to reduce residual free monomers (such as acrylamide) to ultra-low levels, which minimizes downstream ecological toxicity and aligns with strict regional regulations.
R&D is focused on creating composite formulations that combine organic and inorganic polymers into single, stable products. These hybrid coagulants speed up settling rates and improve dissolved air flotation (DAF) performance.
Production factory established in Wuxi, focusing on basic chemical coagulants.
Renamed as Wuxi Bisheng Water Treatment Agent Co., Ltd. and expanded manufacturing space.
Initiated direct international exports, serving major environmental clients in Southeast Asia and Europe.
Annual export and sales revenue exceeded $10,000,000 USD, confirming global footprint.
Established dedicated global trade division, introducing smart dosing systems to overseas markets.
The primary differences lie in aluminum concentration (measured as Al2O3) and basicity. Standard Polyaluminum Chloride (PAC) typically features a basicity of 50%-75% and an Al2O3 content of 10%-30%. Aluminum Chlorohydrate (ACH) is a highly concentrated polyaluminum coagulant with basicity up to 83%-85% and Al2O3 content of 23% (liquid) to 46% (solid powder). This high basicity means ACH will consume far less alkalinity during dosing, resulting in minor pH shifts and significantly lower sludge volume.
WDA is a highly cationic quaternary polymer (dicyandiamide-formaldehyde copolymer). Dyes used in textile industries are usually anionic (sulfonated or carboxylated molecules). The high cationic charge of WDA neutralizes the negative charges on these dye molecules, destabilizing the colloidal dispersion. This charge neutralization causes the chromophores to aggregate and precipitate out as easily filtered or settled organic sediment.
For biological sludge (secondary activated sludge, anaerobic digested sludge), Cationic Polyacrylamide (CPAM) is highly recommended. Biological sludge surfaces carry net negative charges. CPAM neutralized these charges and bridges the particles together. For inorganic mineral sludge, Anionic Polyacrylamide (APAM) is typically preferred. The choice of cationicity and molecular weight depends on the dewatering machinery used (e.g., belt-press, filter-press, or centrifuge).
We operate an ISO 9001 and ISO 14001 certified manufacturing plant. Every production batch undergoes rigorous laboratory testing for active solids content, viscosity, free monomer concentration, bulk density, and heavy metal concentrations (arsenic, lead, cadmium). All chemical raw materials are strictly audited to ensure alignment with international environmental regulations, including EU REACH.
