primarily as a flocculant: For the suspended particles, coarse, high concentrations of positively charged particles, water, PH value is neutral or alkaline water, since the anionic polyacrylamide molecular chain containing a certain amount of polar groups can adsorption of suspended solid particles, so that bridging between the particles to form large flocs. Therefore, it accelerates sedimentation of particles in suspension, has a very significant speed up a clear solution to promote filtering and other effects. The products are widely used in chemical industry waste water, waste water treatment, municipal sewage treatment. Water industry, high turbidity water purification, Shen Qing, coal washing, mineral processing, metallurgy, steel, zinc, aluminum industry, electronic industry and other water treatment;
