When it comes to polyacrylamide, I believe many people will first think of sewage sludge treatment, but many people are not sure why polyacrylamide can be used for sewage sludge treatment. As is well known, the properties of sewage sludge produced by different industries are different, and the treatment methods used are also different.

Usually, polyacrylamide can be simply divided into anions, cations, non ions, and zwitterions. According to the different needs of the industry, it is necessary to choose the correct standard model. If the wrong type of polyacrylamide is used, the sludge treatment effect may be poor.

Generally speaking, cationic polyacrylamide is commonly used for organic sludge treatment, while anionic polyacrylamide is commonly used for inorganic sludge treatment. The concentration of sludge also directly affects the amount of polyacrylamide used.

In addition, when treating sludge, attention should be paid to the size of the flocs during the reaction process, as the molecular weight of polyacrylamide can affect it. During the dehydration process, polyacrylamide must fully react with sludge to produce a better flocculation state and achieve better purification effects. The sludge concentration and viscosity of the solution prepared with polyacrylamide must be appropriate.
