Advantages of the product

Superior Flocculation Efficiency

Our cationic polyacrylamide for wastewater offers exceptional flocculation efficiency, enabling rapid aggregation of suspended solids and colloids. Field trials show up to 40% improvement in settling rates and 30% reduction in polymer usage, ensuring clearer effluent and lower chemical costs.

Enhanced Sludge Dewatering

Significantly enhances sludge dewatering, producing drier cake solids and reducing final disposal expenses. The polymer improves primary and secondary sludge conditioning, cutting moisture content by up to 25% and lowering transport costs.

Rapid Dissolution and Stability

Engineered for rapid molecular unwinding and complete dissolution in cold or hard water. Maintains flocculation efficacy across a broad pH spectrum (pH 4–11) and in high salinity, ensuring reliable performance in complex industrial streams.

In wastewater treatment, cationic polyacrylamide (CPAM) is pivotal for achieving compliance and efficiency. CPAM aggregates small particles into large flocs via electrostatic attraction and polymer bridging, removing COD, BOD, and TSS. At Jiangsu Feymer Technology, we combine deep polymer chemistry with continuous manufacturing to maintain consistency and low residual monomer, helping clients reduce their water footprint.

Frequently Questions

How does cationic polyacrylamide remove pollutants?

Cationic polyacrylamide (CPAM) operates via two principal mechanisms: charge neutralization and polymer bridging. Wastewater particles typically carry a negative surface charge, which prevents them from aggregating. The cationic sites on the polymer bind to these anionic particles, neutralizing the charge and reducing repulsive forces. Simultaneously, the long polymer chains adsorb onto multiple particles, forming bridges that create large, dense flocs. These flocs settle rapidly under gravity or can be removed by dissolved air flotation or filtration.
The optimal dosage varies with the characteristics of the wastewater, including pH, turbidity, organic content, and temperature. Typically, dosages range from 1–10 ppm for high-clarity effluents, but industrial streams with high COD may require up to 50 ppm. It is crucial to perform a jar test to determine the precise dose that produces a clear supernatant with minimal polymer residual. Overdosing can cause restabilization of particles and excessive sludge or polymer residues, while underdosing fails to achieve desired clarification.
