Polyacrylamide can be divided into “anionic, cationic and nonionic polyacrylamide” according to its ionic properties, but the properties of high molecular organic polymers can be divided into anionic and cationic. Although both cationic polyacrylamide and anionic polyacrylamide are used as flocculants in sewage treatment, they are different in effect and principle. What is the difference between the anion and cation of …

Precautions when using polyacrylamide: Test: The selection of polyacrylamide needs to be determined through tests. Choose the right manufacturer, the suitable model, molecular weight, degree of ionization, degree of hydrolysis, etc. The dissolved concentration of polyacrylamide: generally 0.2-0.5%, which should be determined through experiments according to the material characteristics and operating conditions. Mostly 0.2-0.3%. Good dissolution is the …

The coal-washing process produces a large amount of wastewater. These wastewaters contain a large amount of suspended solids, coal slime and other organic matter, if they are directly discharged into the environment without treatment, they will cause serious pollution to the environment. Therefore, coal-washing plant wastewater must be treated to reduce the impact on the …
