The common polyacrylamide is cationic polyacrylamide and anionic polyacrylamide. Both solid polyacrylamide need to be dissolved before use. Can the dissolved cationic polyacrylamide and anionic polyacrylamide be dissolved together and put into sewage for use?
It is certain that due to the characteristics of polyacrylamide, no matter what type of polyacrylamide can not be mixed, dissolved and added together. As for the dissolution of cationic polyacrylamide and anionic polyacrylamide, once they are dissolved in water at the same time, coagulation effect will appear, and massive small particles will appear in water. These small particles are formed by mutual flocculation of cationic polyacrylamide and anionic polyacrylamide. Therefore, after the polyacrylamide dissolved in water is agglomerated and precipitated, There will be no effect of water treatment.
Because of its high viscosity, polyacrylamide will remain on the side wall of the dissolving tank when preparing the water solution. If it is not cleaned and then dissolves other types of polyacrylamide, it will still cause impact, so it needs to be treated reasonably.
Therefore, different types of polyacrylamide need to be dissolved separately. Because of the complexity of wastewater treatment, a variety of chemicals are generally needed to achieve good results, and cationic polyacrylamide and anionic polyacrylamide will also be used together. Then it should be noted that the use method of cationic polyacrylamide and anionic polyacrylamide after reasonable dissolution also needs to be determined by experiments. Cationic polyacrylamide and anionic polyacrylamide cannot be added at the same time.
