PAM Chemical Water Treatment Industrial Sludge Dewatering Cationic Polyacrylamide

Polyacrylamide is a commonly used flocculant product, which has outstanding effects in sewage treatment and other fields, and the contrast effect is obvious. Polyacrylamide is easily soluble in water in the process of sewage treatment, which can effectively reduce the frictional resistance of the liquid. According to the different charged ions, it can be divided into four types: anionic polyacrylamide, nonionic polyacrylamide, cationic polyacrylamide and zwitterionic polyacrylamide.

When treating industrial wastewater, the pH value of the water quality should be considered first. The effective pH range of anionic polyacrylamide is between 5-14, which is effective for treating alkaline, neutral and weakly acidic water, and is mostly used for flocculation and sedimentation; The effective pH range of cationic polyacrylamide is between 5-9, which is more effective for the treatment of acidic and neutral water, and is more used for sludge dewatering; the pH value of non-ionic polyacrylamide is between 1-8. It is effective for the treatment of acidic water.

PAM Chemical Water Treatment: In the application, the classification source of sewage water quality should be considered. At present, sewage treatment is divided into two categories: urban sewage and industrial sewage. Urban sewage treatment is relatively simple, the source is relatively single, and the material composition is basically similar. However, industrial wastewater treatment is more complex. Industrial production varies widely and produces different types of wastewater. When treating industrial wastewater, it is necessary to carry out a comparative test according to the actual situation to select the ideal polyacrylamide model.
