FIELD: separation.

SUBSTANCE: invention relates to rotary disk filters for filtration of water, more specifically to frame disc filters, which are usually supported on a concrete structure, which includes a reservoir for receiving filtered water formed by a disk filter. Frame disk filter is equipped with header of bypass water located near inlet hole in disk filter. Water supplied for cleaning is poured over edge of inlet header of bypass water. Pipeline is communicated with bypass water header to direct bypass water from ram disk filter into waste water channel, which is independent of ram disk filter.
