Advantages of the product

Advanced High-Charge Cationic Polymer for Superior Flocculation

Our PDADMAC polymer is synthesized using cutting-edge aqueous polymerization technology, resulting in a robust cationic charge density typically ranging from 50% to 100% mol. This high charge neutralization capability efficiently destabilizes negatively charged colloids, suspended solids, and organic matter, forming large, dense flocs that settle rapidly. Compared to standard coagulants, our polymer reduces turbidity by up to 30% more at lower dosages. Its tailored molecular weight ensures optimal bridging and charge patch mechanisms, enhancing performance even in variable raw water conditions.

Sustainable Production and Reliable Supply Chain

Feymer is committed to sustainable manufacturing, implementing green chemistry principles in our PDADMAC polymer production. We use energy-efficient processes that minimize waste and emissions, and we continuously recycle auxiliary materials. Our production bases in Jiangsu and Anhui are equipped with advanced automation, allowing for 24/7 production capability and a total annual capacity exceeding 50,000 tons of water-soluble polymers. With five strategic factories, we offer an uninterrupted supply, even during peak seasons or supply chain disruptions.

Comprehensive Technical Support and Customized Solutions

We differentiate ourselves through dedicated technical support and customization capabilities. Our experienced team of water treatment specialists assists in conducting jar tests, optimizing dosage, and designing polymer injection systems to achieve peak performance. We collaborate closely with clients to adapt the polymer’s molecular weight and charge density to specific water types or process requirements. For instance, we can synthesize ultra-high molecular weight PDADMAC for sludge dewatering applications requiring maximum floc strength or lower molecular weight versions for color removal in textile effluents.

In the field of water treatment, selecting the right PDADMAC polymer supplier is as critical as the polymer itself. PDADMAC, or polydiallyldimethylammonium chloride, is a quaternary ammonium polymer widely used as a coagulant and flocculant due to its high cationic charge density. Its mechanism is based on charge neutralization and interparticle bridging, effectively aggregating suspended particles, dissolved organic matter, and colloidal substances. In raw water treatment, PDADMAC helps clarify water for potable use by reducing turbidity and removing natural organic matter, which are precursors to harmful disinfection by-products. In wastewater treatment, it enhances biological floc settling, improves sludge dewatering, and reduces the load on downstream processes. For industrial applications, such as in the pulp and paper industry, PDADMAC is a cost-effective retention aid and drainage enhancer, improving fibre and filler retention while purifying process water.

Frequently Questions

What is PDADMAC and how does it work in water treatment?

PDADMAC (polydiallyldimethylammonium chloride) is a high-charge cationic polymer used to neutralize and aggregate negatively charged particles in water. It functions via two main mechanisms: charge neutralization, where it compresses the electrical double layer of colloids, and bridging, where polymer chains adsorb onto particles to form larger flocs. When added to turbid water, it rapidly induces coagulation, causing suspended matter to clump and settle. It is effective in removing organic compounds, algae, and color from raw water, as well as improving effluent clarity in wastewater. As a supplier, we offer various viscosity grades to match the application, as higher molecular weights facilitate bridging, while lower molecular weights are suitable for direct charge neutralization.
Feymer is a specialized manufacturer with over a decade of expertise in water treatment chemicals, combining cutting-edge production technologies with a robust commitment to quality control.

Customer Testimonials

Maria Santos
Reliable Partner for Municipal Water Treatment

We switched to Jiangsu Feymer's PDADMAC for our city's drinking water treatment plant two years ago, and the difference is remarkable. The product consistency is superb, allowing us to reduce dosage by 15% compared to our previous supplier, while achieving the same effluent turbidity—even during seasonal algal blooms. Their technical team conducted a thorough on-site audit and provided us with a tailored dilution and dosing setup that streamlined our operations. The after-sales service is genuinely attentive; they check in regularly and deliver promptly, even during supply chain constraints.

David Chen
Excellent Performance in Industrial Wastewater

Our plant treats a complex effluent from fine chemical manufacturing, including high COD and charged surfactants. Feymer's PDADMAC product, used as a primary coagulant, has significantly improved our clear water separation and reduced our chemical costs by 20%. The flocs are dense and rapid-settling, which increased our throughput. We also value their technical responsiveness; they helped us adjust the polymer grade to optimize performance when our feed composition changed. Their product quality is stable, with no batch variation issues.

State-of-the-Art Manufacturing Facilities

State-of-the-Art Manufacturing Facilities

Jiangsu Feymer Technology operates three production bases and five factories in the Yangtze River Delta region, specifically in Jiangsu and Anhui provinces. These facilities are equipped with advanced automation and continuous process control systems, ensuring high throughput and consistent product quality. For PDADMAC production, we utilize a proprietary water-phase polymerization technique that yields high molecular weight polymers with narrow molecular weight distribution. Reactors are constructed with high-grade stainless steel and lined with non-corroding materials to prevent contamination. The entire process—from monomer feeding to polymer finishing—is monitored by in-line sensors and a central distributed control system (DCS), allowing real-time adjustments to maintain optimal reaction parameters (temperature, initiator concentration, and stirring rate). This results in a highly reproducible product, batch after batch.
Integrated Supply Chain Management

Integrated Supply Chain Management

As a vertically integrated company, we source key raw materials, including dimethylamine and allyl chloride, from certified suppliers, and we also produce the monomer DADMAC (diallyldimethylammonium chloride) in-house. This integration allows us to control monomer purity and ensure reliable feedstock availability, independent of market fluctuations. We maintain strategic inventory levels of raw materials to buffer against supply disruptions. The entire production cycle is synchronized, from monomer synthesis to polymer drying and packaging, reducing lead times and providing flexibility to meet urgent orders. Our logistics team handles international shipping with documentation such as CE, ROHS, and other compliance. We also sustain safety stock of finished PDADMAC products in various regions through our export distribution partners, enabling faster delivery to any port.
