<p>A filter module (1) comprising filtering layers (4, 4a, 4b) composed of a filter medium is described, in which layers of first and second draining spacing elements (10, 20) alternate and the draining spacing elements show, in an alternating sequence with respect to the filtrate chambers and the non-filtrate chambers throughflow elements (11, 21) on one side and sealing elements (12, 22) on the other side. In order to improve filtration and to make it possible to fulfil additional aims with reference to filtration and treatment of the fluid, whilst retaining a solid construction, the filter module (1) is equipped with third spacing elements (30). Between two filtering layers (4, 4a, 4b), which are disposed between a first and second spacing element (10, 20), there is disposed at least one such third spacing element (30) which has sealing elements (31, 32) adjacent the filtrate chamber (3) and the non-filtrate chamber (2). A process for the production of a filter module that is at least partially filled with treating material is also described.</p> |
