Anionic polyacrylamide, referred to as APAM, the product appearance is white powdery particles. Is organic polymer flocculant, coagulant aid, is a water-soluble polymer, due to its molecular chain contains a certain amount of negative group, it can pass the suspended solid particles in the water adsorption, adsorption by bridging between the particles and charge neutralization, forming large lumps of flocculation, under the influence of gravity, speed up the settlement of sus...
