9003-05-8 Anionic Polyacrylamide,
Hongzheng 90% Polyacrylamide Flocculant Water Treatment
Dyeing Wastewater/ Electroplating Wastewater Treatment Polyacrylamide PAM Anionic/ Cationic
Polyacrylamide, an acrylic resin that has the unique property of being soluble in water. It is employed in the treatment of industrial and municipal wastewater.
Polyacrylamide powders include cationic polyacrylamide(CPAM),anionic polyacrylamide(APAM)and nonionic polyacrylamide(NPAM),used for water treatment,oilfield,mineral processing,papermaking and other application areas.

1. Municipal sewage
Polyacrylamide can promote the rapid aggregation and sedimentation of suspended particles to achieve separation and clarification by means of electrical neutralization and its own adsorption bridging effect. It is mainly used for the flocculation and sedimentation of the front stage of the sewage treatment plant and the dewatering of the sludge in the back stage.
2. Industrial wastewater
When polyacrylamide is added to the water of suspended turbid particles, through the electrical neutralization and the adsorption bridging effect of the polymer itself, the suspended particles can quickly agglomerate and settle, so as to achieve the effect of separation and clarification, and then Improve work efficiency and reduce operating costs.
3. Paper industry
Polyacrylamide is widely used as retention aid, filter aid, dispersant, etc. in the papermaking field.
Non-ionic PAM is mainly used to improve the filterability of pulp, increase the strength of dry paper, and increase the retention rate of fibers and fillers.
Anionic PAM is mainly used as a dry and wet strengthening agent and retention agent for paper; cationic copolymers are mainly used for papermaking wastewater treatment and filter aid, and also have a good effect on increasing the retention of fillers.
In addition, PAM is also used in papermaking wastewater treatment and fiber recycling.
4. Coal industry
Coal washing wastewater, coal slurry water from coal preparation plants, and ground washing wastewater from coal-fired power plants are all a mixture of water and fine coal. Its main characteristics are high turbidity, fine particle size of solids, and more negative charges on the surface of solid particles. Choose the appropriate PAM flocculant to strengthen the treatment of slime water.
