High-basicity inorganic coagulants and high-molecular organic polymers designed for rapid sediment settlement and molecular charge neutralization.
The global demand for industrial and municipal wastewater treatment chemicals is undergoing a paradigm shift. Historically, simple metal salts like alum and ferric chloride dominated primary sedimentation. However, modern environmental regulations like the EU Industrial Emissions Directive and EPA Zero Liquid Discharge (ZLD) mandates have driven chemical formulations toward higher molecular efficiency, lower sludge generation, and minimal chemical residue.
This dynamic has propelled advanced polymers like Aluminum Chlorohydrate (ACH) and Poly(diallyldimethylammonium chloride) (PDADMAC) to the forefront. These agents offer higher basicity and charge density, meaning lower dosages are required to achieve the same or better flocculation metrics. As chemical factories in China embrace digital synthesis and intelligent reaction systems, the batch consistency of these complex polymers has reached unprecedented heights, making them reliable staples for critical processes from membrane pretreatment to high-velocity sedimentation.
Founded in 1998, Wuxi BS Water Treatment Chemicals Co., Ltd. possesses advanced production technology and rich management experience. We specialise in producing a series of water treatment products for the treatment of drinking water and various types of domestic and industrial wastewater.
With 27 years of deep industry expertise, Wuxi BS has grown from a regional manufacturer to a global supplier, exporting advanced chemical solutions worldwide via distributors since 2007. We run highly automated production lines backed by a comprehensive quality control system, ensuring our chemical output meets international environmental and performance parameters.
Equipped with digital intelligent solid feeding systems since 2025.
ISO certified pathways ensuring systematic consistency across all output grades.
Tailored molecular weights, charge densities, and basicity parameters configured for specific industrial effluents and wastewater matrices.
| Chemical Agent Class | Active Ingredient (Al2O3 / Polymer Content) | Primary Mechanisms | Target Industrial Sector |
|---|---|---|---|
| Polyaluminium Chloride (PAC) | Solid (28%-30%), Liquid (10%-15%) | Charge neutralization, sweep flocculation, colloidal entrapment | Municipal drinking water, pulp & paper, urban sewage plants |
| Aluminum Chlorohydrate (ACH) | High Basicity (up to 83%), Al2O3 ≥ 23% | Destabilization of negatively charged colloids at wider pH ranges | Membrane filtration pretreatment, cosmetics, municipal purification |
| Polyacrylamide (PAM - APAM/CPAM) | Anionic, Cationic, Non-ionic polymers | Polymer bridging, floc stabilization, shear-resistant cake formation | Sludge dewatering, petroleum recovery, mineral washing |
| Water Decolorizing Agent (WDA) | High-density Cationic Dicyandiamide Copolymer | Complexation of anionic dye chromophores, rapid precipitation | Textile processing, dye houses, printing ink effluents |
| PDADMAC | Strongly Cationic quaternary ammonium polymer | Electric double layer compression, rapid mud-water separation | Oil recovery processing, paper retention, high-turbidity water plants |
Optimizing PAC and CPAM dosing ratios dramatically reduces primary sedimentation times. Proper charge neutralization results in robust floc strength, preventing break-up under the shear stresses of belt presses and centrifuges.
Our polymers break emulsified oil-in-water complexes. High-charge cationic polymers neutralize the surface charges on oil droplets, facilitating fast separation in API oil-water separators and DAF units.
Specifically target high retention dynamics. Highly charged ACH and PDADMAC agents neutralize anionic trash, resulting in less fiber loss, improved drainage, and cleaner wire cycles.
Prevent membrane fouling by pre-coagulating colloidal matter with low-dose ACH, minimizing dissolved aluminum carryover to downstream reverse osmosis (RO) and nanofiltration elements.
