Application of polyacrylamide in industrial wastewater

As a commonly used water treatment agent, polyacrylamide is widely used in industrial wastewater. Today I will briefly explain the role of polyacrylamide in industrial wastewater.

Sewage treatment and industrial wastewater treatment require flocculants such as polyacrylamide for flocculation, clarification and purification. In mechanical dewatering, polyacrylamide must be used for effective pretreatment to improve the performance of sludge and the production efficiency of mechanical equipment. Among them, cationic polyacrylamide is widely used for sludge dewatering treatment.

Now, with the increase of urban population, the number of urban sewage treatment plants is also increasing. The sludge of the water plant needs to be dewatered uniformly, and the sludge must meet the requirements of dewatering and discharge. At present, sewage treatment plants in large cities in my country generally adopt the sludge dewatering process, and the amount of polyacrylamide in the urban water supply will also increase rapidly.

Polyacrylamide is a very important aspect in industrial wastewater treatment. Large petrochemical companies also pay great attention to environmental protection, and most of them use polyacrylamide as a catalyst.
