Explore our high-performance line of chemical agents designed to solve complex flocculation, coagulation, and sludge dewatering challenges.
Navigating tight discharge regulations requires highly technical chemical approaches to sewage and complex effluent streams.
Worldwide, regulatory standards for municipal and industrial sewage are intensifying. In areas like the EU, North America, and East Asia, standard limits for Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Total Suspended Solids (TSS), and heavy metal complexes are tighter than ever. Outdated precipitation methods often fall short when treating complex organic dyes, suspended colloids, and recalcitrant sludge.
As a leading wholesale manufacturer, Wuxi BS Water Treatment Chemicals offers high-charge cationic agents and structural coagulants. Our chemistry addresses the core issue of electrical double-layer repulsion in suspended colloids, destabilizing particles rapidly to improve settleability and sedimentation speeds.
Our solutions target zero-liquid discharge (ZLD) plant configurations, membrane pretreatment circuits, and large-scale municipality clarifiers, minimizing both chemical consumption footprints and total disposal costs.
Bridging chemical theory with robust manufacturing capabilities to support demanding municipal and industrial configurations.
Engineered for high charge-neutralization capacity, our PAC options span different basicity scales (up to 85% basicity) to ensure effective coagulation across a wide pH range. Polymeric Aluminium Ferric Chloride (PAFC) combines the fast settling speeds of iron ions with the low turbidity advantages of aluminum polymers, making it ideal for low-temperature, low-turbidity raw waters.
Available in anionic (APAM), cationic (CPAM), and nonionic (NPAM) formats with ultra-high molecular weights (up to 22 million). Our PAM series provides strong polymer bridging chains, aggregating small flocs into large, shear-resistant structures suitable for centrifuge, belt filter, or plate-and-frame dewatering equipment.
Our Water Decolorizing Agents (WDA) are highly active cationic quaternary polymers formulated to complex with colored compounds (particularly anionic dyes), precipitating them rapidly out of the effluent. When paired with PDADMAC, they serve as excellent coagulant aids, enhancing organic matter removal and preventing membrane fouling.

A history of engineering evolution, building capacity, and expanding our global wastewater treatment partnership footprint.
The manufacturing factory was established to produce basic inorganic coagulants for regional water grids.
Renamed Wuxi Bisheng Water Treatment Agent Co., Ltd. and upgraded to a multi-line industrial chemical synthesizer.
Our custom-formulated polymers began direct export to European, North American, and Southeast Asian distributors.
Annual sales values crossed the $10,000,000 threshold, marking significant global market expansion.
Established a dedicated foreign trade division to support international clients with direct technical and logistics services.
Our production practices are ISO-compliant and certified to meet international health, safety, and environmental standards.
Aligning polymer formulations with green manufacturing goals and global environmental standards.
The next generation of water treatment chemistry must reduce environmental impact. Wuxi BS is actively researching biodegradable, bio-based flocculants to replace traditional synthetic options in sensitive discharge areas. Our goal is to lower residual monomer concentrations (specifically free acrylamide) to less than 0.025% in cationic polymers, helping municipal drinking water plants meet safety regulations.
Additionally, we are optimizing the inorganic-organic coagulant ratio within our complex formulations. By combining the rapid neutralizing effects of PAC with the high-bridging capability of polyamines, we help operators reduce their total chemical footprint, lowering salt addition levels and mitigating secondary pollution.
For international supply chains, compliance is essential. Wuxi BS products are formulated to align with REACH registration requirements for European shipments, comply with US EPA standards for municipal discharge, and meet Chinese GB standards for municipal water purification. We provide complete technical data sheets (TDS) and safety data sheets (SDS) for our products, ensuring smooth transport and safe industrial handling.
Formulated for specific effluent challenges, from heavy metal precipitations to concentrated dye decoloring.
Technical answers to common queries regarding industrial coagulants and polymer chemistry.
Polymeric Aluminium Ferric Chloride (PAFC) incorporates iron ions alongside polymeric aluminum. The iron component increases the floc weight, accelerating sedimentation speeds and improving performance in low-temperature or low-turbidity conditions, whereas standard PAC relies primarily on charge neutralization via aluminum hydroxide species.
The choice depends on the surface charge of your suspended solids. APAM is ideal for inorganic suspensions, mining wastewater, and neutral-to-alkaline pH levels. CPAM is best suited for organic sludge (such as municipal sewage) and acidic industrial waste, where it neutralizes negatively charged organic particles to improve dewatering.
Basicity represents the ratio of hydroxyl ions to aluminum ions. Higher basicity (such as 83-85% in ACH) means less alkalinity is consumed during dosage. This minimizes pH drops in treated water, generates less sludge, and forms larger, more stable flocs compared to low-basicity coagulants.
Wuxi BS's cationic Water Decolorizing Agent (WDA) complexes with anionic dye molecules. It neutralizes their surface charges, causing them to precipitate as stable flocs that can be easily removed by sedimentation or dissolved air flotation (DAF).
PDADMAC acts as a coagulant aid. By neutralizing dissolved organics and small colloids before they reach ultrafiltration (UF) or reverse osmosis (RO) membranes, it reduces fouling and decreases the frequency of chemical clean-in-place (CIP) cycles.
Solid polymers (like PAC and PAM) are hygroscopic. They should be stored in a cool, dry, and well-ventilated warehouse, kept sealed in their original moisture-resistant packaging, and raised off the floor on pallets to avoid contact with ground moisture.
