Polyacrylamide is a water-soluble polymer that is very important in the water treatment industry, and its properties include flocculation, adhesion, thickening, and resistance reduction. According to its ionic characteristics, it can be divided into four major categories: cationic polyacrylamide, anionic polyacrylamide, nonionic polyacrylamide and zwitterionic polyacrylamide.
Polyacrylamide must be dissolved in water before it can be added. It can not be directly added to the sewage. There is also a certain requirement for the pH of the tap water when preparing the solution. The water temperature in winter is low, and the dissolution rate of polyacrylamide will be slow, which can be appropriately increased. Water temperature, but it should be noted that when the water temperature exceeds 40 degrees, the polymer will accelerate degradation and the effect will be compromised.
