High-purity chemical compositions designed for coagulant optimization, wastewater treatment, and advanced solid-liquid separation processes.
Understanding the transition from traditional monomeric salts to complex polynuclear polymeric structures for optimal coagulation performance.
Aluminium Chlorohydrate (ACH) is a specialized, highly concentrated inorganic polymer characterized by high basicity (typically 83%). Unlike conventional polyaluminium chloride (PAC) variants which contain lower proportions of active Al13 and Al30 polymers, ACH leverages a dense network of highly stable polymeric aluminum species. This molecular configuration provides maximum charge neutralization per unit mass, drastically reducing sludge volume, bypassing the need for alkaline additions, and optimizing operating budgets.
In municipal drinking water purification, paper production sizing, and cosmetic antiperspirant manufacturing, chemical consistency is paramount. As a leading manufacturer with 27 years of industry experience, Wuxi BS Water Treatment Chemicals Co., Ltd. has developed specialized reaction technologies to control the hydrolysis and polymerization phases. This ensures that every batch maintains a narrow basicity distribution, minimizing residual aluminum in processed effluents and maximizing turbidity removal efficiency.
Founded in 1998, Wuxi BS Water Treatment Chemicals Co., Ltd. is a modern tech-driven company focused on the research, development, and manufacturing of advanced flocculants and coagulants. With operations extending over decades, we have established ourselves as a dependable strategic partner for global bulk sourcing.
We specialize in producing a high-performance series of water treatment chemicals, including High-Basicity Aluminium Chlorohydrate (ACH), Polyaluminium Chloride (PAC), Polyacrylamide (PAM), and Poly(diallyldimethylammonium chloride) (PDADMAC) to satisfy the rigorous requirements of drinking water standards and industrial wastewater systems globally.
Our intelligent production plant supports digital dosing systems, zero-caking solid granular processing, and highly controlled chemical synthesis. Through a commitment to performance, we have expanded our capacity to meet global demand, shipping to municipal facilities, pulp mills, and chemical distributors across six continents.

How procurement teams can mitigate logistics risks, ensure batch consistency, and verify chemical authenticity.
Basicity represents the degree of polymerization of the aluminum molecules. Buyers must demand certificates of analysis highlighting accurate basicity. Lower basicity translates to high chemical consumption and excess acidity, while standard 83% basicity ACH optimizes dosing budgets.
Choosing high-potency ACH over alum or low-basicity PAC can reduce sludge output by up to 50%. This yields direct savings in dewatering polymers, storage overheads, filter-press cycles, and industrial waste disposal taxes.
Standard solid PAC and ACH powders often absorb moisture in damp environments, leading to blockages in mechanical feeders. Wuxi BS uses proprietary drying processes to produce low-dust, free-flowing granules that resist caking.
From heavy industrial runoff to cosmetic purity standards, see how our customized formulas deliver target metrics.
In acidic and neutral papermaking processes, ACH works as an excellent anionic trash catcher (ATC) and sizing promoter. It neutralizes dissolved colloidal contaminants, accelerating drainage rates, and improving fiber retention without damaging paper machine components.
Oil refineries discharge wastewater containing emulsified hydrocarbons, organic color compounds, and suspended solids. By combining CPAC and specialized Water Decolorizing Agents (WDA), Wuxi BS enables plants to separate oil-water emulsions and discharge clear effluent within standard regulatory limits.
For municipal water plants treating cold or low-turbidity raw water, traditional metal salts react slowly, leaving high residual metal levels. High-basicity ACH forms large, heavy flocs rapidly, ensuring clear drinking water while conforming to strict heavy metal guidelines.
Exploring the future of eco-friendly water chemistry and precision manufacturing technologies.
In response to international carbon reduction initiatives, Wuxi BS is transitioning to closed-loop chemical synthesis. By reclaiming steam from the reaction processes and utilizing green energy in our spray-drying lines, we have successfully reduced the carbon footprint of our solid ACH and PAC products by 18% over the past three years. This supports procurement organizations aiming to optimize their Scope 3 upstream emissions.
Our technical team is also focusing on composite formulations. By cross-linking inorganic polymeric aluminum with synthetic polymers like PDADMAC or Polyacrylamide, we are developing single-component flocculants. These simplify chemical storage, reduce dosage requirements, and lower chemical costs for water treatment facilities.

Answers to common technical and chemical selection questions from our industrial research laboratory.
The primary differences lie in the basicity and concentration of Al2O3. ACH is synthesized to have a basicity of 83% to 85%, which is the highest possible basicity for a stable inorganic aluminum solution. Standard PAC ranges from 50% to 75% basicity. Because of this high basicity, ACH has a higher density of polynuclear aluminum complexes, meaning it requires less product to treat raw water, minimizes sludge volume, and causes minimal pH drop.
Coagulation reactions typically lower the pH of raw water. Traditional alum or low-basicity PAC consume alkalinity rapidly, requiring operators to add lime or soda ash to maintain target pH levels. With a basicity of 83%, ACH consumes almost no alkalinity, bypassing the need for pH adjustment chemicals. This reduces chemical storage costs and simplifies system maintenance.
Liquid ACH remains stable for 12 months when stored in a cool, ventilated area, away from direct sunlight and incompatible substances like strong bases. Solid ACH powder can be stored for 24 months, provided it remains sealed in its original multi-layer packaging to prevent moisture absorption and caking.
Yes. Wuxi BS manufactures high-purity ACH that meets the specifications required for municipal potable water treatment. It efficiently removes turbidity, natural organic matter (NOM), and color without leaving high levels of residual dissolved aluminum in the treated drinking water.
