The viscosity of polyacrylamide solution mainly reflects the internal friction resistance generated by the flow or relative movement between liquid molecules. The internal friction resistance is related to the structure of the polymer, the properties of the solvent, the concentration of the solution, and the temperature and pressure. The larger its value, the greater the …

Reason 1: The influent volume suddenly increases, the retention time of the secondary sedimentation tank is shortened, and the activated sludge flows out of the secondary sedimentation tank before it can settle, resulting in sludge running. At the same time, the increase in influent concentration will lead to the enhanced activity of activated sludge, which …

Classification of polyacrylamide Polyacrylamide can be divided into nonionic, anionic and cationic polyacrylamide. Non-ionic: (NPAM), neutral, uncharged. ① Neutral or acidic sewage is more commonly used, such as mineral processing wastewater, stone factories, engineering mud, and printing and dyeing factories. ② The flocculation effect mainly relies on a large number of molecular groups on the …
