As a linear polymer flocculant, polyacrylamide has the appearance of white particles. Because its molecular chain contains a certain amount of polar genes, it can absorb solid particles suspended in water, and bridge the particles to form large flocs. It can accelerate the sedimentation of the particles in the suspension, and has a very obvious effect of accelerating the clarification of the solution and promoting filtration.
Nonionic polyacrylamides are linear polymers with high molecular weight and low ionicity. Because of its special group, it contains the functions of flocculation, dispersion, thickening, bonding, film-forming, gelling, and stabilizing colloid. As a sewage treatment agent, when the suspended sewage is acidic, it is more suitable to use non-ionic polyacrylamide as a flocculant.
Non-ionic polyacrylamide contains a certain number of polar groups in its molecular chain, which can form large flocs by adsorbing solid particles suspended in water, bridging between particles or through charge neutralization. Therefore, it can accelerate the sedimentation of particles in the suspension, and has a very obvious effect of accelerating the clarification of the solution and promoting filtration.
The application scope of non-ionic polyacrylamide mainly includes flocculation and sedimentation of various industrial wastewater, sedimentation and clarification treatment; wastewater treatment in mineral processing and metal smelting process; wastewater treatment in iron and steel plants and stone processing plants.
