In recent years, with the rapid development of China's industry, the water pollution caused by industrialization is severe, and the treatment of the water environment is not optimistic. Polyacrylamide is the most effective water treatment agent used in sewage treatment flocculants. Let's explain which kind of polyacrylamide to choose in industrial sewage:
The activated sludge method is usually used for the treatment of common industrial sewage. Biochemical sludge is often a colloid with strong hydrophilicity, and its organic content is particularly high. It is particularly difficult to dehydrate. To deal with this problem, we suggest to select the type according to the nature of sludge, and usually use the corresponding type of cationic polyacrylamide. The model is mostly polyacrylamide, which is divided into anionic polyacrylamide, cationic polyacrylamide and non-ionic polyacrylamide.
