anionic polyacrylamide

The use of cationic polyacrylamide in the form of 0.1-0.2% water solution, the use of tap water preparation, preparation should pay attention to is that the dry powder of polyacrylamide evenly, dispersed into the constant mixing of water, and ensure that the water are dispersed individual particles, can not form a group, otherwise, once the formation of large particles, it is difficult to continue to dissolve, the formation of large particles of water. The preparation should be thoroughly stirred to dissolve it. The prepared solution is easy to hydrolyze and can be applied the same day.

Cationic polyacrylamide should be effectively mixed after being added in sewage or sludge, the mixing time is generally 10-30 seconds, generally not more than 2 minutes. The specific dosage of polyacrylamide is closely related to the concentration, properties and treatment equipment of colloids and suspended solids in sewage or sludge. The amount of sewage treatment is generally within 3-10PPM, and 3-10g is added per ton of water. The amount of sludge treatment is more, and the amount should be obtained through a large number of experiments.

In the process of sewage treatment, if some sewage alone using cationic polyacrylamide or polyaluminum chloride can not achieve the ideal effect, you can consider the use of polyacrylamide and polyaluminum chloride, sometimes will achieve good results, make sewage treatment more simple and convenient.
