Filter module, used for clarifying and treating liquids, comprises alternating layers of filter medium and draining spacer elements having connecting devices in region of filtrate or non-filtrate chamber

Filter module comprises alternating layers of filter medium and draining spacer elements with flow elements and sealing elements for the filtrate chamber and the non-filtrate chamber. The spacers allow the filter layers to be pressed in a sealing manner, and they have connecting devices in the region of the filtrate or non-filtrate chamber to interact with the connecting devices of at least one spacer element. Filter module consists of layers (4a, 4b) of filter medium alternating with layers (10, 10a, 10b, 20) of draining spacer elements having flow elements (12a, 12b, 22) and sealing elements (11a, 11b) for the filtrate chamber (40) and the non-filtrate chamber (41). The spacer elements are formed in such a way that they allow the filter layers to be pressed in a sealing manner and they have connecting devices in the region of the filtrate or non-filtrate chamber to interact with the connecting devices of at least one spacer element. Preferred Features: The connecting devices of neighboring spacer elements interact. The spacer elements have a drainage element (100, 200), a sealing element (11a, 11b, 21) and/or a flow element (12a, 12b, 22). The invention relates to a filter module (1) comprising filter layers (4a, b) made of a filter medium, especially comprising filter layers made of filter strata. Said filter layers alternate with layers made of draining spacer elements (10, 10a, b, 20), the first and last layer of the filter module (1) consisting respectively of a draining spacer element (10a, b, 20). The draining spacer elements respectively and mutually comprise flow elements (12a, b) and sealing elements (11a, b) for the filtrate chamber and the non-filtrate chamber (40, 41). Means are provided for the mutual connection thereof. The aim of the filter module (1) is to combine the advantages of known filter modules with improved sealing at the edges of the filter layers, and to make the filter module backwashable. The filter module (1) comprises draining spacer elements (10, 10a, b, 20) which are embodied in such a way that they enable the filter layers to be pressed in a sealing manner. At least some of the draining spacer elements (10, 10a, b, 20) comprise connecting means in the region of at least one filtrate chamber or non-filtrate chamber (40, 41), which co-operate with the connecting means of at least one other spacer element. The connecting means include lugs, stirrup straps (16a, b, 23a, b), and T and arrow-shaped catch elements. In this way,
