Cationic Polyacrylamide performance is excellent,The formed flocs are produced quickly, separated quickly, and they are dense, highly resilient, and have good dehydrating properties.
Cationic Polyacrylamide Mechanism Of Action
Charge neutralization: The organic colloidal particles in the sludge usually carry a negative charge, while the Cationic Polyacrylamide molecular chains are equipped with positive charge groups such as quaternary ammonium salts. When Cationic Polyacrylamide is added to the sludge, the positive charge groups are attracted by electrostatic forces to the negative charges on the surface of the sludge particles, significantly reducing the electrostatic repulsion between the particles and causing the negatively charged suspended particles to lose their dispersion stability
Bridging adsorption: The long molecular chains of Cationic Polyacrylamide (with a molecular weight of 8 million - 15 million) further enhance the flocculation effect through adsorption bridging. A single Cationic Polyacrylamide molecule can simultaneously adsorb multiple sludge particles, forming a three-dimensional network structure, which causes the suspended particles to aggregate into larger particles and accelerate their sedimentation
Reaction precipitation: React with negatively charged dissolved substances to form insoluble precipitates.

Cationic Polyacrylamide Application Fields
Sewage treatment
① Sludge dewatering: Cationic Polyacrylamide used for mechanical dewatering of municipal sludge and industrial sludge , such as belt press filters, centrifuges, etc., which can reduce the viscosity of the sludge cake and improve the dewatering efficiency.
② Organic wastewater treatment: Treating high-concentration organic wastewater from alcohol plants, meat processing plants, by neutralizing charges to remove suspended solids and chemical oxygen demand (COD).
③ Oil-containing wastewater treatment: In the treatment of oil extraction wastewater and oilfield reinjection water, it can reduce the oil content and prevent formation blockage.
Paper industry
① Paper dry strength agent: Cationic Polyacrylamide can form hydrogen bonds with fibers, increasing the connection force between fibers, significantly improving the dry strength of paper, enabling the paper to maintain shape stability during production and reducing damage.
② Retention agent: Cationic Polyacrylamide can promote the sedimentation of fibers and the separation of impurities through adsorption and bridging, improving the retention rate of pulp fibers and fillers, and reducing raw material loss and wastewater discharge.
③ Retention agent: Promotes water separation, increases the drying speed of paper, and saves energy.
Textile printing and dyeing industry: Treating dye wastewater to reduce color and suspended solids content, and can also be used as softening agent and static prevention agent in the textile printing and dyeing process.
Mining and coal separation industry: Cationic Polyacrylamide can be used as a clarifying agent for mine wastewater and coal washing wastewater, making the wastewater purified and achieving water resource recycling.
Water treatment plants: Cationic Polyacrylamide used as a flocculant for water treatment in water plants using river water sources, with low dosage, good effect, and low cost. Especially when used in combination with inorganic flocculants, the effect is even better.
