Sewage treatment plant, in the two stage treatment of water and iron sulfate coagulant, after two sink filter cloth, the result of filter cloth filter is easy to block, may I ask what is the reason, how to solve?
After filtration in the two sink filter, the filter cloth filter is easy to stop. This is a design defect. It is necessary to increase the sand filter with multi-layer gradation before the filter cloth filter, if not increase, it will shorten the operation cycle.
Check backwash time according to field backwash. Extended backwash time is certainly better than short time. The filter block of belt filter press stops the mud and carries out backwashing, and the time is decided by the degree of washing.
Because the pore size of filter cloth filter is very small, it is easy to block the SS after coagulation. The washing cycle depends on your blockage.
