Advantages of the product

Exceptional Charge Density and Purity

Synthesized with high cationic charge density, Feymer's polydadmac achieves rapid neutralization of colloidal particles. With a purity level exceeding 99% and unreacted monomer residuals below 0.5%, it is ideal for sensitive drinking water applications. The uniform molecular weight distribution guarantees predictable performance, lower dosage requirements, and up to a 35% reduction in sludge volume for municipal and food processing facilities.

Stability Across Broad pH and High Salinity

Unlike traditional coagulants that fail under extreme conditions, our polydadmac retains high efficacy across pH 2 to 12 and in high-salinity environments. This resilience makes it ideal for complex industrial wastewater, oilfield produced water, and textile dyeing effluents. It operates smoothly without extensive pH adjustments, simplifying process control while reducing additional chemical consumption.

Superior Sludge Dewatering and Settling

Feymer's polydadmac promotes rapid formation of dense, easy-settling flocs. In sludge conditioning, it reduces cake moisture significantly, lowering transport and disposal costs. When used in papermaking, it serves a dual role by clarifying process water and enhancing fiber retention, helping plants cut overall chemical and energy costs by up to 20%.

Polydadmac (Polydiallyldimethylammonium chloride) is a quaternary ammonium polymer valued globally for its superior charge neutralization and bridging efficiency. Its high positive charge density enables effective destabilization of negatively charged colloidal particles across municipal drinking water, textile dyeing, paper production, and oilfield operations. At Jiangsu Feymer Technology Co., Ltd., advanced polymerization technology limits unreacted monomer residuals to under 0.5%, guaranteeing safety in potable water systems. Operating three major production bases with five specialized factories, Feymer integrates AI-empowered quality management systems to monitor molecular weight distribution and charge density in real time. In practical water treatment operations, incorporating polydadmac alongside polyaluminum chloride (PAC) cuts PAC consumption by 30% to 50%, generating lighter chemical sludge and reducing operational costs.

Frequently Questions

What are the primary polydadmac uses in water treatment?

Polydadmac is extensively used as a primary coagulant and flocculant in drinking water clarification and wastewater treatment. In potable water applications, it removes fine turbidity, organic matter, and color while drastically reducing the dosage of inorganic salts needed. In industrial wastewater, polydadmac effectively treats complex effluents from textile dyeing, chemical processing, and oil refining by lowering COD and removing heavy metals. Its strong cationic charge density allows it to perform exceptionally well even in cold or low-turbidity raw water where traditional coagulants often fail. Additionally, it serves as a superior sludge conditioner, accelerating dewatering and improving cake solids across municipal and industrial treatment plants.
Unlike alum, which relies on aluminum hydrolysis, polydadmac is a pre-formed cationic polymer that neutralizes charge rapidly at much lower dosage levels. Alum introduces metallic ions that create large amounts of hydroxide sludge, whereas organic polydadmac significantly reduces sludge generation and disposal burdens. Furthermore, polydadmac remains effective across a wide pH range from 2 to 12, whereas alum is restricted to an optimal pH window of 5.5 to 8.0. Combining polydadmac with alum can reduce total inorganic chemical consumption by 30% to 50%. Its high biodegradability and low toxicity also lower environmental impact during discharge.
