A novel embodiment of a Filtration Unit with cleanable permeate side, formed by an internally channeled flat filter plate (1) formed by bonding of two flat half filter plates (2, 3), the filter effect formed by perforation slits or holes (10) in the surface of the plates, said perforations connecting to channels (9) inside the plate. The channels inside the plates are for permeate leading to two or more paired exits (4, 5) perpendicular to the plate, the plate exits forming exit channels for permeate to exit the Filtration Unit. The paired exits makes it possible to clean the permeate site of the Filtration Unit by flushing cleaning media from one exit (4 or 5) to the other exit (4 or 5). The filter area surface (6) can be covered by bonding a fine filter (7), typically an organic flat sheet membrane, to the filter surface, whereby very fine micro or ultra filtration or even molecular filtration can be achieved. |
