The planar filtration element comprises a planar support structure 11 and at least one filtration layer 12, 13 provided with membrane material, the planar support structure being spaced apart and fixed by the spacing members 113. Two opposing outer surfaces 111, 112 to define a drainage compartment 114 between the first and second outer surfaces, the at least one first and second outer surfaces defining the drainage compartment 114. ) And through-openings 115 for fluid connection, wherein the outer surfaces 111 and 112 are formed of a material that extends continuously throughout the outer surfaces when ignoring the through-openings 115. And the filtration layers 12, 13 coat the outer surface such that the membrane material penetrates the through-openings 115 and anchors the filtration layers 12, 13 to the support structure 11. |
