High-performance cationic polymers and inorganic coagulants manufactured directly under advanced Quality Assurance frameworks for maximum water clarification efficiency.
In modern industrial processes, the optimization of water systems is highly dependent on high-efficiency flocculants. PDADMAC (Polydiallyldimethylammonium chloride) represents a class of highly effective quaternary ammonium cationic polymers that has fundamentally revolutionized solid-liquid separation. As wastewater guidelines grow increasingly stringent across the globe, industrial operators are pivoting from conventional inorganic salts (such as Alum and Ferric Chloride) toward advanced organic polymer systems.
The fundamental chemistry of PDADMAC—specifically its high charge density and stability across a wide pH range (0.5 to 14)—renders it the ideal agent for electrostatic charge neutralization. Under contemporary water treatment protocols, the primary objective is to lower chemical oxygen demand (COD), neutralize suspended colloidal solids, and minimize the resultant sludge volume. Our factory is positioned at the forefront of this market shift, manufacturing specialized liquid and solid versions designed to enhance flocculation kinetics while significantly reducing operating costs.
Founded in 1998, Wuxi BS Water Treatment Chemicals Co., Ltd. integrates high-end chemical synthesis, rigorous laboratory QC protocols, and automated manufacturing systems to supply global partners.
Leveraging Wuxi's regional chemical industrial integration, our plant implements advanced automation across synthesis, polymerisation, and packaging. This smart-manufacturing design limits variance in monomer-to-polymer conversion rates, resulting in uniform molecular weight distributions.
Faced with unpredictable global logistics, our 20,000-ton capacity buffer warehouse ensures uninterrupted supply lines for international distributors and large-scale industrial consumers. This structural availability limits exposure to ocean transit volatility and raw material pricing shifts.
Evaluating PDADMAC against traditional water treatment reagents across critical industrial parameters.
| Coagulant/Flocculant Type | Effective pH Range | Sludge Volume Production | Dosage Efficiency | Salt Tolerance | De-coloring Capability |
|---|---|---|---|---|---|
| PDADMAC (Organic Cationic) | 0.5 - 14 (Highly Stable) | Very Low (Compact Flocs) | Excellent (0.5 - 5 ppm) | High | High (Direct anionic dye complexation) |
| Polyaluminum Chloride (PAC) | 5.0 - 9.0 (Moderately Stable) | Medium | Moderate (10 - 50 ppm) | Medium | Moderate |
| Aluminum Chlorohydrate (ACH) | 5.5 - 8.5 | Medium-Low | Moderate-High | Medium | Low |
| Traditional Alum | 6.0 - 7.5 (Narrow Range) | High (Gelatinous Hydroxides) | Low (50 - 150 ppm) | Low | Low |
How PDADMAC polymers deliver custom-tailored separation dynamics in key processing sectors.
When used as a primary coagulant aid, PDADMAC significantly reduces the required dosage of inorganic coagulants like PAC. By neutralizing negatively charged humic acids and dissolved organic carbon, it reduces turbidity levels and prevents downstream membrane biofouling.
Within produced water treatment systems, PDADMAC plays a vital role in de-oiling processes. The high-charge density cationic polymer destabilizes oil-in-water emulsions, allowing rapid coalescence and floatation of residual hydrocarbons for recycling or safe disposal.
In closed-loop paper mills, PDADMAC acts as a pitch controller and retention aid. It neutralizes anionic trash in the pulp slurry, ensuring cellulose fiber binding, maximizing chemical retention, and expediting sheet dewatering on modern high-speed paper machines.

Key metrics for water engineers and procurement managers when choosing polymer concentrations.
PDADMAC is typically marketed in aqueous forms ranging from 10% to 50% active content. Procurement agents must assess the exact chemical concentration to prevent excessive freight charges on inactive water weight.
Viscosity profiles (typically 1,000 to 40,000 cps) determine the dilution mechanics and pumping requirements. Higher molecular weight equates to higher viscosity, influencing the polymer's bridging action during flocculation.
For municipal drinking water applications, residual DADMAC monomer limits must remain under strict levels (frequently < 0.1% or 1000 ppm) to ensure compliance with NSF/ANSI 60 standard requirements.
