Treatment of Municipaland Industrial Wastewater

The treatment of municipal and industrial sewage is mainly divided into two types according to the source of sewage, namely: municipal sewage and industrial sewage. In the treatment of these two kinds of sewage, the more commonly used treatment method is to add polyacrylamide.
Municipal sewage: refers to the sewage discharged into the urban sewage system. At the same time, municipal sewage also includes domestic sewage and industrial sewage. When polyacrylamide is used as a flocculant for municipal sewage, cationic polyacrylamide is usually used. Depending on the water quality, Sewage analysis experiments have to be done to determine the specific model.
Industrial wastewater is mainly divided into: organic wastewater containing mainly organic pollutants, inorganic wastewater containing inorganic pollutants, mixed wastewater containing both organic and inorganic substances, wastewater containing radioactive substances, and cooling water polluted only by heat, and Heavy metal wastewater.
The selection of polyacrylamide is mainly based on the different types of charges carried by the sewage water quality. According to the characteristics of the water quality, cationic polyacrylamide, anionic polyacrylamide, non-ionic polyacrylamide, etc. are selected, and the product model is selected through experiments.
