Advanced Product Classification

Custom-grade chemicals synthesized to resolve distinct physical-chemical parameters in decentralized wastewater.

Polyaluminum Chloride (PAC) Aluminum Chlorohydrate (ACH) Polyacrylamide (PAM) Water Decolorizing Agent (WDA) Poly(diallyldimethylammonium chloride) (PDADMAC)

Polyaluminum Chloride (PAC)

Available in spray-dried white and light-yellow granular forms. Highly effective for rapid charge neutralization, forming robust flocs in varying turbidities of domestic household influent.

Aluminum Chlorohydrate (ACH)

An inorganic coagulant characterized by high basicity (up to 83%) and Al2O3 content (up to 24% liquid, 46% solid). Minimizes pH disruption and reduces sludge volume in local treatment tanks.

Polyacrylamide (PAM)

Synthesized in high-molecular-weight Anionic (APAM) and Cationic (CPAM) polymer strings. Facilitates bridging mechanism, producing large flocs for rapid gravity settling and sludge dewatering.

Chemistry of On-Site Wastewater Flocculation

Understanding the molecular dynamics required for efficient, decentralized home wastewater clarification.

Decentralized sewage treatment systems—such as residential septic tanks, multi-family aerobic treatment units (ATUs), and integrated greywater filtration loops—handle complex waste streams. Domestic wastewater contains suspended solids, organic proteins, kitchen lipids, surfactants from detergents, and pathogenic microorganisms. Destabilizing these colloidal suspensions requires a balanced sequence of coagulation and flocculation.

1. Double-Layer Compression & Charge Neutralization

Colloidal particles suspended in household wastewater carry negative electrostatic surface charges, preventing them from aggregating. The addition of inorganic coagulants like Polyaluminum Chloride (PAC) or Aluminum Chlorohydrate (ACH) introduces highly charged cationic aluminum species (such as Al13 polymer clusters like [Al30O8(OH)56(H2O)24]18+). These species neutralize the negative charges of the colloids, compressing the electrical double layer and allowing the particles to aggregate through van der Waals forces.

2. Polymeric Bridging Mechanics

Once the initial micro-flocs are formed, high-molecular-weight organic polymers like Polyacrylamide (PAM) are introduced. The long polymer chains of PAM adsorb onto multiple micro-floc particles simultaneously. This bridging mechanism builds larger, denser macro-flocs. In household sewage treatment, Cationic PAM (CPAM) is highly effective because it binds directly with negatively charged organic biological solids, optimizing gravity-settling clarifiers and mechanical press configurations.

3. Emulsified Oil and Surfactant Co-Precipitation

Residential greywater contains high concentrations of emulsified oils, fats, and chemical surfactants. Specialty organic coagulants, such as PDADMAC (Poly diallyldimethylammonium chloride) and cationic Water Decolorizing Agents (WDA), break these emulsions. They form insoluble complexes with the anionic surfactants, allowing them to be settled out alongside organic particulate matter.

Macro Industry & Local Application Scenarios

How Wuxi BS formulations are deployed across diverse residential and industrial wastewater environments.

Sewage Treatment Icon

Decentralized Domestic Septic Systems

Our low-dust PAC and high-solubility CPAM granules are integrated directly into automated dosing chambers of decentralized household sewage systems. These chemicals speed up primary clarification, preventing organic overload of sub-surface soil absorption fields and drain fields.

Membrane pretreatment

Membrane Process Pretreatment

Advanced residential MBR (Membrane Bioreactor) systems use our high-basicity ACH and PDADMAC. These coagulants pre-settle colloidal solids and organic polymers, preventing membrane fouling, reducing cleaning cycles, and extending the operational lifespan of the membranes.

Drinking water treatment

Drinking Water Clarification

For rural, community-level drinking water systems, Wuxi BS supplies drinking-water-grade PAC (PAC-01) and ACH conforming to ANSI/NSF Standard 60. These chemicals effectively remove natural organic matter (NOM) and reduce turbidity while keeping residual heavy metal levels well within safety limits.

The Advantage of Partnering with a Leading Chinese Manufacturer

Why global procurement managers trust Wuxi BS for supply chain resilience, cost efficiency, and technical precision.

Direct Raw Material Sourcing & Cost Control

Located in the heart of China’s chemical industrial corridor, Wuxi BS has direct access to key raw materials, including high-grade bauxite, hydrochloric acid, and pure acrylonitrile. This localized supply chain insulates our clients from global price volatility.

Scale-Driven Quality Consistency

Our fully automated, digital DCS-controlled reactor systems run continuously. This automation ensures that molecular weights, cationicity densities, and basicity indexes remain consistent from batch to batch, meeting tight performance tolerances.

Custom Formulations for Specialized Systems

We provide custom product tailoring (such as modifying Al2O3 ratios, molecular weight spreads, or liquid active ingredient concentrations) to match the temperature, pH, and flow profiles of specific domestic treatment equipment designs.

Frequently Asked Questions (FAQ)

Common questions regarding water treatment chemistry, product selection, and global logistics.

What is the difference between PAC and ACH in domestic wastewater applications? +

Polyaluminum Chloride (PAC) is a versatile, cost-effective coagulant suitable for a wide range of turbidity and temperature levels. Aluminum Chlorohydrate (ACH) is a highly concentrated, high-basicity (typically 83%) inorganic coagulant. ACH is preferred in systems with limited space, as its high charge density reduces sludge volume and minimizes pH drops in treated wastewater.

How do I determine the correct dosage of Polyacrylamide (PAM) for home sewage clarifiers? +

Dosage depends on suspended solids (SS) concentration, charge characteristics, and the clarifying equipment used. We recommend performing laboratory jar tests to optimize the dosage. Over-dosing can cause dispersion and increase chemical oxygen demand (COD), while under-dosing leads to incomplete clarification. Wuxi BS technical representatives are available to assist with water sample testing and dosage profiles.

Are Wuxi BS chemicals compliant with international environmental and health standards? +

Yes. Our chemicals are manufactured under ISO 9001:2015 Quality Management and ISO 14001:2015 Environmental Management certifications. For drinking water applications, our raw materials and purification processes comply with international safety standards, keeping trace heavy metals well below global regulatory thresholds.

What are the lead times and storage requirements for bulk polymer orders? +

Typical lead times range from 7 to 15 days, depending on custom packing and formulation requirements. Solid polymers should be stored in cool, dry warehouses away from moisture and direct sunlight. Liquid formulations should be stored in corrosion-resistant tanks (such as plastic, FRP, or lined steel) and protected from freezing temperatures.
