How to choose polyacrylamide
Polyacrylamide stars cationic polyacrylamide, anionic polyacrylamide, nonionic polyacrylamide, an amphoteric polyacrylamide, four species. The application of various models, when selected should also understand the the polyacrylamide knowledge and information in order to help their own to use the most appropriate polyacrylamide. The following is a choice polyacrylamide Dongying City, Shun Tak Chemical Co., Ltd. for everyone.
1, in general, cationic polyacrylamides for the treatment of organic sludge, anionic polyacrylamide used in the inorganic sludge, not highly alkaline leather with a cationic polyacrylamide, the strong acid should not be used anionic polyacrylamide , high solid content, the amount of the sludge usually polyacrylamide is also large.
Floc size: by selecting the molecular weight of the polyacrylamide can adjust the size of the floc.
3, degree of polyacrylamide ion: for sludge dewatering, flocculants can be used in different ionic degree by a small test first screening.
4,Floc strength: floc under shear should remain stable and not broken.
5, polyacrylamide and sludge mixing: polyacrylamide in a certain position of the dewatering equipment must be fully and sludge reaction, flocculation occurs. To this end, the viscosity of polyacrylamide solution must be appropriate.
6, the dissolution of polyacrylamide: dissolution good to hair and give full play flocculation
