Module filter comprising at least one admission for the non-filtrate and at least one discharge for the filtrate and comprising at least one filter module

A module filter comprising:

• a container comprising at least one container housing, a container bottom, at least one admission for a non-filtrate, and a discharge for a filtrate;
• at least one filter module arranged in said container housing comprising several stacked, disc-shaped filter cells, each filter cell substantially comprising first and second filter material layers, each filter material layer having an inner surface and an outer surface, the filter material layers having peripheral edges that are connected sealingly together, the filter cell having a hollow inner space between the filter material layers and further comprising a central opening wherein said central openings of the several filter cells form at least one central channel in fluid communication with said hollow inner space of each of said filter cells;
• a support element in each filter cell, the support element contacting and spacing apart the inner surfaces of each filter material layer, the support element comprising a ring and having an outer diameter, wherein the peripheral edges of the filter material layers are radially spaced from the outer diameter of the support element to provide said hollow inner space, the ring having openings providing fluid communication between said central channel and said hollow inner space of said filter cell;
• said central channel communicating with said admission for the non-filtrate during a filtration mode of said module filter;
• said container housing having a space surrounding said filter cells wherein said space communicates with said discharge for the filtrate;
• circular disc-shaped drainage support bodies arranged between said filter cells, wherein said drainage support bodies extend at least approximately over the entire outer surface of the filter material layers of said filter cells;
• said drainage support bodies having a plurality of drainage channels, respectively, wherein said drainage channels extend radially toward an outer rim of said drainage support bodies;
• said drainage support bodies having projections projecting axially away from both sides of said drainage support bodies, said projections being suitable for contacting an outer surface of an adjacent filter material layer and extending in a radial direction of said drainage support bodies;
• wherein between said projections intermediate spaces are defined;
• and
• wherein said intermediate spaces form said radial drainage channels and are configured to remove the filtrate.
