PLATE FILTRATION MODULE

The invention relates to a module for the filtration of liquid mediums, especially for purifying waste water, comprising a plurality of essentially planar and flexible filter membrane pockets comprising at least one opening which drains the inner area thereof. Said pockets are arranged in a vertical and parallel manner and are arranged, preferably, at the same distance from each other in a rigid, essentially square supporting element in such a manner that the intermediate gaps arranged between adjacent filter membrane pockets can be intensively crossflown by a liquid. According to the invention, the filtration module in characterised in such a manner that the filter membrane pockets are fixed to closed side surfaces opposite the supporting element, preferably over the entire length thereof, such that the supporting element comprises at least one evacuation line which is used to evacuate the liquid which is suctioned out via the filter membrane pocket openings, and that the filter membrane pockets have a flexible, liquid-permeable core and/or a plurality of flexible liquid-permeable core elements and that the rod or grid-shaped supporting elements are provided on or at a distance from each filtration membrane pocket.
