Polyacrylamide treatment of sewage is not good? That is, you did not choose the right type.
- Jun 11, 2018 -

Although polyacrylamide is favored by everyone in sewage treatment, it is not omnipotent. It can solve all problems without one type, and the types and types of polyacrylamide needed for different water quality are also different. The nature of the sewage produced by different enterprises is different. Some are acidic, some are alkaline, some are neutral, some contain oil pollution, some contain a large amount of organic matter, some contain color. Some contain a lot of sediment, there are a variety of circumstances, the nature of the sewage has a variety of circumstances. It really takes a lot of effort to deal with the sewage. So, how can we better and more reasonably choose the appropriate polyacrylamide?201405231710215306.jpg


In general, cationic polyacrylamide is used to treat acidic wastewater and anionic polyacrylamide is used to treat alkaline wastewater. Of course, sewage with neutral water quality is relatively alkaline and acidic sewage is relatively easy to treat. If the water quality is too acidic, it is generally very difficult to treat. The usual practice is to add alkali to the sewage and adjust the pH of the sewage. Make the sewage neutral best. This is the easiest to handle, and can save processing costs. On the contrary, if the sewage shows a large alkaline strength, it is necessary to add acid to adjust the pH of sewage. Even if the sewage is neutral, it is not the type of polyacrylamide that can treat the sewage well and reach the discharge standard. This has to do with an accurate selection problem. The usual practice is to do a small scale test in the laboratory. Through repeated experimental comparison, the best model is selected, and then the model selected is tested in the actual production process to see if it is appropriate in production.
