mainly used as flocculant: for suspended particles, coarse, high concentration, particles with positive charge, water PH value of neutral or alkaline sewage, due to anionic polyacrylamide molecular chain contains a certain amount of polar base can absorb suspended solid particles in water, so that the formation of large flocculant bridging between particles. Therefore, it accelerates the sedimentation of particles in suspension, accelerates the clarification of solution and p...
