Polyacrylamide is abbreviated as PAM, which has the name of "Auxiliary Agent", and is widely used in sewage treatment. Many users think that polyacrylamide for sewage treatment only needs to distinguish between anions and cations. In fact, there are hundreds of models of polyacrylamide. Not one model can solve all problems. All sewage of different water quality can be treated to reach standards. Different sewage needs to use corresponding polyacrylamide products. When it comes to the issue of model selection, Capitel Chemical will give an introduction with you.
The nature of sewage produced by different enterprises is different. Some are acidic, some are alkaline, and some are neutral. Some contain greasy dirt, some contain a lot of organic matter, some contain color, and some contain a lot of There are various conditions of the sediment, and the nature of sewage has various conditions. To deal with these sewage, it is indeed necessary to work hard. So, how can wastewater treatment choose better and more suitable polyacrylamide?
Generally speaking, cationic polyacrylamide is good for sewage with acidic water quality, and anionic polyacrylamide is good for sewage with alkaline water. Of course, sewage with neutral water quality is relatively easy to treat with alkaline and acidic sewage. If the acidity of the sewage is too strong, it is generally difficult to treat. The usual method is to add alkali to the sewage to adjust the pH of the sewage to make The sewage reaches neutrality. This is easier to handle and can save processing costs. Conversely, if the sewage shows high alkalinity, acid should be added to adjust the pH of the sewage. Even if the sewage is neutral, not that type of polyacrylamide can treat the sewage well and meet the discharge standard. This has a more accurate selection problem. The usual way is to do a small test in the laboratory and pass Repeated experiments and comparisons, select models with better experimental results, and then check whether the selected models are suitable in production during the actual production process.
