How To Choose Polyacrylamide In Diffierent Industry


As we all know, Polyacrylamide(PAM) also named industry additives, It is widely used in sewage treatment. But it is not a panacea, not a model can solve all the problems, all the different sewage treatment standards, different sewage needs to use the corresponding product, there is a problem how to choose the appropriate flocculant? Here we will give you an introduction for this question.

The nature of sewage produced by different enterprise,some are acidic water, alkaline water and some water, is neutral, some contain oil, some contain large amounts of organic matter, containing some color, some contain large amounts of sediment, as well as a variety of circumstances, nature of sewage have different situation.

In general,Cationic Polyacrylamide has a good effect on acidic sewage,anionic polyacrylamide has a good effect on alkaline sewage.Of course, the water quality of neutral sewage is relatively alkaline and acidic sewage is easy to deal with, if the acidic water quality of sewage is too large, is generally difficult to handle, the usual approach is to add alkali to the sewage, adjust the pH of the sewage, so that Sewage to neutral the best. So the most easy to deal with, but also can save processing costs. Conversely, if the sewage showed alkaline strength, it is necessary to add acid to adjust the pH of the sewage. Sewage is neutral, not the kind of polyacrylamide can be the sewage treatment is good, to discharge standards, which have a more accurate selection problem, the usual practice is to do a small test in the laboratory, through Repeated experiments, select the best experimental model, and then in the actual production process to test whether the selected models in production is also appropriate.
