Scope of Action of Polyacrylamide


In terms of performance, polyacrylamide is more suitable for the treatment of various sewage, not only the effect is significant, but also the effective prevention of secondary pollution. This makes the sewage treatment problem that has received much attention, so that it can be better solved. So what are the specific functions and scope of polyacrylamide?

The more extensive role is still applied to sewage treatment. When treating sewage, the model of the product should be selected according to the nature of the sewage. Polyacrylamide can be used before the sludge enters the filter press. The flocs produced during dehydration are relatively large, and it is not easy to stick to the filter cloth when the filter press is filtered. The flow sludge cake is thicker and the dehydration rate is relatively high. In the treatment of domestic sewage and organic wastewater, because polyacrylamide presents positive electricity in both the coordination and alkaline media, the sewage with negatively charged suspended particles in the sewage is flocculated and precipitated.

Polyacrylamide can also be used in papermaking. As a reinforcing agent for papermaking, it can improve the retention rate of pigments and the strength of paper. In addition, it can also be used in oilfield economics and learning aids, textile sizing agents, etc. Polyacrylamide is an organic polymer flocculant, which can enhance the coagulation effect through the adsorption and bridging of its chain molecules, and effectively increase the size of floccules. Through the effects of bridging flocculation and network flocculation, the flocs are tightly combined, and the particle settling speed is accelerated, so that the chroma and the removal rate of organic matter can be improved.

Polyacrylamide is still widely used in sewage treatment, and its effect is no less than that of some water treatment equipment. At present, the problem of water pollution has attracted the attention of many people, and it is very common to choose a suitable sewage treatment agent for treatment.
