View DetailsWastewater derived from textile processing, particularly dyeing and finishing operations, is widely recognized as one of the most challenging streams to treat due to its high chemical oxygen demand (COD), dynamic pH fluctuations, structural resistance of synthetic dyes, and significant concentrations of dissolved salts. In response to increasingly strict municipal regulatory thresholds, global textile operators must transition beyond simple sedimentation treatments to integrated chemical clarification processes utilizing highly specialized polymers.
At Wuxi BS Water Treatment Chemicals Co., Ltd., our 27 years of technological research and industrial application expertise have led to the development of advanced formulations that target specific dye groups. Reactive, direct, and acid dyes are highly water-soluble anionic molecules. Traditional coagulants often fail to break down their complex molecular rings. Our signature Water Decoloring Agent (WDA) leverages cationic polymer chemistry to neutralize these anionic charges, forming insoluble, dense organo-metallic complexes that precipitate rapidly.
By using highly active quaternary ammonium polymers, our formulations exhibit high cationic charge density. This forces immediate destabilization of suspended negatively charged dye particles. The addition of high-molecular weight Anionic Polyacrylamide (APAM) then bridges these destabilized micro-flocs into large, rapid-settling macro-structures, significantly optimizing decanter centrifuge and DAF clarifier run times.

The chemical treatment of textile industrial wastewater is undergoing a fundamental shift. Innovations are driven by the search for lower sludge yields, reduced chemical consumption, and compliance with the Zero Discharge of Hazardous Chemicals (ZDHC) guidelines. The technical roadmap of Wuxi BS focuses on transitioning from purely mineral-based coagulants (like PAC and PAFC) to sophisticated organic-inorganic composite materials. These composite formulations reduce aluminum residue in treated water, prevent pipe scale, and ensure compliance with municipal drinking water feedstock safety thresholds.
Our development pipeline prioritizes biodegradable cationic flocculants and high-density, salt-tolerant polycarbonates. As textile factories implement reverse osmosis (RO) and nanofiltration (NF) membrane systems to recover up to 90% of process water, chemical pretreatment must protect these membranes from biofouling and organic adsorption. The introduction of high-basicity Aluminum Chlorohydrate (ACH) and ultra-pure PDADMAC offers superior particle aggregation with minimal ionic disruption, extending membrane life by up to 35% compared to standard PAC.
| Chemical Agent Class | Primary Active Mechanism | Target Pollutants | Optimal Application Phase |
|---|---|---|---|
| Water Decoloring Agent (WDA) | Charge neutralization & polymeric encapsulation | Soluble Reactive, Acid & Direct dyes, refractory COD | Dye effluent primary clarification loop |
| Composite PAC / CPAC | Alum-silicate colloid destabilization | Suspended solids, mineral turbidity, emulsified oils | Influent processing and primary sedimentation |
| PDADMAC (Cationic) | High charge-density flocculation | Organic humic matter, micro-colloids, surfactants | Membrane protection pre-treatment filtration |
| Anionic Polyacrylamide (APAM) | Polymer bridging and micro-floc consolidation | Flocculated suspended matter, inorganic muds | Sludge thickeners and belt press dewatering |

View ClassificationWastewater management is no longer just a compliance cost. In modern circular industrial setups, it is an essential component of resource recovery. Our macro chemical treatment solutions are customized for various industrial applications, ensuring that chemicals are used efficiently and system reliability is maintained:
Sewage & Municipal Wastewater Treatment: High-charge anionic flocculants combined with basic PAC optimize primary clarifier sedimentation and secondary biological settling. This reduces organic loading to municipal biological stages by up to 45%.
Petroleum & Petrochemical Processes: Demulsifying polymers target oily emulsions, splitting hydrophobic organic droplets from the water phase for easy skim collection, protecting biological treatment steps.
Membrane Filtration Pretreatment: Utilizing high-purity ACH and low-molecular-weight cationic polymers ensures that colloidal silica and organic carbon are removed before water enters microfiltration (MF) and reverse osmosis (RO) systems.
Paper & Pulp Mill Effluents: Customized retention aids and dewatering flocculants increase fiber recovery, control white-water cycles, and accelerate fiber sludge pressing operations.
China's chemical manufacturing sector has evolved from simple raw material processing to high-precision, digitally controlled production. At Wuxi BS, our digital manufacturing platform integrates real-time inventory management with precise chemical dosing reactors. This setup ensures batch-to-batch consistency for complex polymers like PAC, CPAC, and PDADMAC. With an annual sales volume exceeding 500,000 tons and a finished product warehouse holding over 20,000 tons, we offer a highly reliable supply chain to global distributors and textile mills.
In August 2025, Wuxi BS introduced advanced digital intelligent solid feeding equipment.

Technical and commercial answers from our laboratory and logistics teams.
PAC is an inorganic coagulant that aggregates suspended solids by destabilizing mineral colloids. It is less effective for highly soluble anionic dyes. Our cationic polymer Water Decoloring Agent (WDA) specifically binds and precipitates dissolved dye molecules. For optimal performance, we recommend using a dual system: WDA for primary dye destabilization, followed by a low dosage of PAC to build denser, faster-settling flocs.
Aluminum Chlorohydrate (ACH) has a high basicity (up to 83%), compared to 50%-65% for standard PAC. This high basicity provides more active polymeric aluminum ions, allowing for a lower dosage. It also maintains water pH, reducing the need for neutralizing chemicals like sodium hydroxide, while generating lower volumes of sludge.
Our ISO 9001 certified plant uses automated polymerization reactors that monitor temperature, viscosity, and molecular weight in real time. Each batch undergoes testing for charge density, viscosity, and active content. We retain reference samples of all shipments for two years to ensure trace stability.
