<p>A filtering installation comprises two cartridge filters (34) each containing a filter cartridge (7) formed of an inner filtering element (9) and of an outer filtering element (10). The filtering elements (9 and 10) are separated by a flow channel (13) and are arranged on a housing plate (5). The cartridge filters (34), respectively the filter cartridges (7) are connected in parallel to a feeder channel (35). The flow channel (13) of each filter cartridge (7) opens out in a reflux channel (38). The housing plate (5) is welded to the casing wall (6) by the welding seams (33) and the two parts are rigidly connected. The passage section of the inlet opening (3) is larger than the passage section of the evacuation channel (13). Thereby, it is possible to obtain a hydrostatic pressure up to 10 Kg/cm<2>, and therefore a liquid flow rate in the order of 250 m<3>/h.</p> |
