Anionic polyacrylamide is a water-soluble polymers. Due to its molecular chain containing a certain number of , it can adsorption the solid particles suspended in water, bridging between the particles or the particles flocculation by charge neutralization to form large flocs. So it can accelerate the sedimentation of particles in suspension, have a very clear clarification for filtering . Mainly used for various industrial wastewater flocculation, sedimentation clarification treatment, such as steel plant wastewater, electroplating plants and waste water, coal washing waste water sewage treatment, sludge dewatering. It can also be used for drinking water clarification and purification. Features
