Explore our industrial range of high-efficiency coagulants, flocculants, and customized color removal agents direct from our Factory 4.0 production center.
A comprehensive technical analysis of flocculation, charge neutralization, and chemical formulations driving modern municipal and industrial wastewater recycling.
Wastewater management has evolved from simple compliance-driven sediment settlement to sophisticated Zero Liquid Discharge (ZLD) protocols. At the heart of this process lies the physical chemistry of coagulation and flocculation. Raw sewage contains stable colloidal suspensions that carry negative surface charges. The primary role of our inorganic coagulants, including Polyaluminium Chloride (PAC) and Aluminum Chlorohydrate (ACH), is to destabilize these colloidal suspensions via double-layer compression and charge neutralization.
ACH, characterized by its exceptionally high basicity (typically exceeding 83%), presents a highly charged polymer structure [Al2(OH)5Cl]n. This structure exhibits a high positive charge density, which effectively neutralizes the negative surface charge of suspended clay particles, algae, and organic matrices. Compared to conventional alum, ACH requires up to 50% less dosage and leaves minimal residual aluminum, significantly reducing downstream filter backwash frequencies and sludge volume.
For more demanding organic matrices, such as those containing complex humic substances or industrial dyestuffs, cationic polymers like PDADMAC and customized Water Decoloring Agents (WDA) are used. These polymers provide strong charge neutralization alongside polymer bridging, aggregation, and rapid sedimentation. This dual-action mechanism is essential for municipal sewage processing plants targeting strict chemical oxygen demand (COD) and total suspended solids (TSS) reduction targets.
Our formulations achieve precise monomer and polymer distributions, ensuring efficient coagulation kinetics even in low-temperature and low-turbidity conditions.
We prioritize formulation pathways that decrease heavy metal concentration in the resulting sludge, enabling simplified sludge disposal and agricultural recycling where permitted.

Aluminum Chlorohydrate (ACH) is a highly concentrated aluminum-based coagulant with a typical basicity of 83% or higher, whereas Polyaluminium Chloride (PAC) basicity generally ranges from 50% to 80%. ACH has a higher positive charge density, requiring lower dosages and resulting in less pH drop during treatment.
We provide Certificate of Analysis (COA) documents for every batch, detailing active ingredients, basicity, density, and pH parameters. We also supply MSDS, ISO 9001/14001 documentation, and third-party inspection reports (such as SGS) upon request.
Yes. Our R&D team can adjust the molecular weight and charge densities of cationic and anionic Polyacrylamide (PAM) as well as PDADMAC products to match the specific filtration and dewatering requirements of your facility.
Depending on port location and stock availability, custom synthesis orders typically ship within 14–21 days of order confirmation. Standard items stored in our 20,000-ton warehouse can be prepared for port delivery in Wuxi/Shanghai within 7–10 days.
