STACK OF MEMBRANE FILTER POCKETS COMMONLY POTTED AT THEIR CORNERS

摘要

The invention relates to a filter element (1) for cleaning liquids, comprising a stack of at least two filter membrane pockets (2), which are substantially flat and comprise a flexible, liquid-permeable filter material for retaining waste particles and/or microbes, wherein each filter membrane pocket (2) has a substantially polygonal shape with at least three corners (3) and a corresponding number of edges (4), wherein the filter membrane pockets (2) are stacked with a defined distance and aligned with each other, wherein aligned corners (3) of the filter membrane pockets (2) are embedded in a casting (5) covering only part of the adjacent edges (4) such that the casting (5) for each corner (3) is spaced from the castings (5) of the neighbouring corners (3).
