FILM-TYPE FILTER FROM HOLLOW FIBERS Russian patent published in 2011 - IPC B01D63/04 B01D65/02 

FIELD: process engineering.

SUBSTANCE: invention relates to film-type filter 7 from hollow fibers for filtration of initial solution on forcing it through film made up of hollow fibers immersed in work bath 24. Filtered fluid discharge channels (12a and 12b) are communicated with filtered fluid discharge pipeline (11) via open-and-shut valves (26a and 26b), respectively, pipeline (11) is communicated with suction port of suction pump (25), open-and-shut valve (30) is communicated with pipeline (11), in its turn, communicated with discharge port of suction pump (25), backwash channels (29a and 29b) are communicated via open-and-shut valves (28a and 28b) with backwash main line (27) branched from the section between open-and-shut valve (30) and section pump (25) of pipeline (11), channels (29a and 29b) comprises multiple hollow-fiber filtration film modules (16a and 16b).

EFFECT: ruling put wash pump or backwash tank in wash-out of suspensions or similar sticking.
