Direct supply options for primary coagulants and advanced flocculants engineered for chemical sedimentation and clarification systems.
Water treatment additives play an essential role in municipal water filtration, industrial wastewater management, and process water purification systems. Modern factories require chemical additives that are highly pure, chemically stable, and conform to international regulatory and environmental standards. As global industries shift toward sustainable chemistry and zero-liquid-discharge (ZLD) technologies, manufacturing plants must produce flocculants, coagulants, and scale inhibitors that optimize water usage while minimizing environmental impacts.
In high-turbidity water systems, standard precipitation is not enough to meet chemical processing guidelines. Primary coagulants like Poly Aluminium Chloride (PAC) and Aluminum Chlorohydrate (ACH) work by neutralizing negative surface charges on suspended particles. This destabilization allows microscopic solids to aggregate. Once these micro-flocs are formed, polymeric bridging agents—specifically Anionic and Cationic Polyacrylamides (PAM)—link them together into larger, fast-settling flocs. This combination of inorganic charge neutralization and organic polymer bridging is the foundation of high-efficiency liquid-solid separation in wastewater processing.
For more challenging chemical compositions, such as wastewater from textile dyeing or paper manufacturing, specialized reagents like Polymeric Aluminium Ferric Chloride (PAFC) and Poly(diallyldimethylammonium chloride) (PDADMAC) are required. These complex polymers are formulated to capture colloidal organic dyes, heavy metal complexes, and mineral pulps, producing clear, treatable discharge water.
A Technology Leader with 27 Years of Expertise in Water Treatment Chemistry
Wuxi BS Water Treatment Chemicals Co., Ltd. is a global manufacturer of advanced chemical agents used in municipal drinking water purification, urban sewage plants, and industrial process loops. By leveraging modern production infrastructure, we ensure that every batch of PAC, PAM, ACH, and PDADMAC meets international safety and regulatory standards.
We provide customized formulas to help industries optimize water recycling rates, cut solid waste handling costs, and meet stringent regulatory requirements. Our facilities produce chemical solutions that consistently deliver high performance in variable water conditions.
Meeting international environmental mandates through next-generation chemical formulations and optimized process technologies.
Global environmental regulations are tightening limits on residual metal ions, particularly dissolved aluminum in municipal drinking water. Innovation in this field is centered on High-Basicity Aluminum Chlorohydrate (ACH) and hybrid composite flocculants that reduce the chemical footprint by up to 35% while maintaining rapid settling times.
Heavy industries such as mining, refining, and chemical processing are moving toward closed-loop water systems. Our high-performance polyacrylamides and decoloring agents assist plants in concentrating brines and separating complex organic contaminants, facilitating water reuse rates exceeding 98%.
Modern water treatment plants increasingly utilize smart sensors and real-time chemical dosing systems. This technology requires chemicals with stable viscosity profiles, highly consistent particle size distribution, and predictable dissolution properties to prevent pipeline clogging and system downtime.
Our formulations are designed to meet the operational parameters and water quality requirements of major global industries.
Wuxi BS Water Treatment Chemicals Co., Ltd. operates state-of-the-art production lines designed for reliability and chemical stability. By monitoring critical process parameters throughout the synthesis of PAC, ACH, and PAM, we ensure high purity, consistent activity levels, and uniform particle sizes. Our automated control systems allow us to adjust key characteristics, such as raw material ratios and molecular weights, to match client specifications.
Through our dedicated technical support team, we assist clients from initial water analysis through chemical selection and dosage optimization. If a customer is dealing with high silica concentrations, heavy metal loads, or extreme variations in pH, we can customize parameters such as molecular charge densities, active ingredient percentages, and solution viscosities. We specialize in producing custom liquid and dry formulations that integrate seamlessly into existing chemical dosing systems.
With an annual production capacity exceeding 500,000 tons and a dedicated warehouse holding up to 20,000 tons of finished products, Wuxi BS is equipped to maintain stable supply chains for large-scale municipal and industrial operations. Our facilities are designed for safe bulk packaging and dynamic container loading, ensuring efficient transit to major ports and reliable delivery to global distribution hubs.

Detailed technical answers addressing common chemical selection, dosing, and operational challenges.
A: The primary differences lie in basicity and aluminum oxide (Al2O3) concentration. PAC typically has a basicity of 50%-80% and contains 28%-30% Al2O3 in powder form. ACH is highly polymerized, featuring a basicity of 83% or higher and containing approximately 23%-24% Al2O3 in liquid form. The high basicity of ACH means it consumes less alkalinity during water treatment, reducing the need for post-treatment pH adjustment with lime or caustic soda.
A: CPAM selection depends on the surface charge of the organic sludge solids. Organic waste sludge, such as municipal biological sludge, is typically negatively charged. A laboratory jar test is used to identify the optimal cationic charge density (ranging from 10% to 80% charge) that achieves effective charge neutralization and polymer bridging, resulting in large, stable flocs that dewater efficiently under mechanical shear.
A: PAFC combines the charge-neutralizing capabilities of aluminum ions with the heavy, rapid-settling floc properties of iron salts. The inclusion of iron helps generate high-density flocs that settle quickly, which is particularly effective in cold, low-turbidity waters or for removing colloidal silica, complex sulfides, and heavy metals from industrial effluents.
A: WDAs are highly cationic, low-molecular-weight polymer formulations. They work by neutralizing the negative charges on dissolved organic dye molecules, such as those found in textile wastewater. This neutralization causes the dyes to destabilize and form insoluble complexes that are easily captured and removed by primary coagulants or dissolved air flotation (DAF) systems.
A: Dry polyacrylamide powders are stable for up to 24 months when stored in a cool, dry place in their original, sealed packaging to prevent moisture absorption. Diluted aqueous solutions of PAM degrade more rapidly and should ideally be used within 24 to 48 hours of preparation to prevent loss of molecular weight and performance.
