<P>PROBLEM TO BE SOLVED: To provide a membrane cartridge capable of setting a flow channel area wide, capable of suppressing the degradation of the strength of a filtering plate, capable of suppressing the flowing channel width between membrane cartridges from becoming uneven with an immersion type membrane separation device filled with the plurality of membrane cartridges parallel, and capable of preventing the occlusion of flowing channels among the membrane cartridges and the occlusion of the filtering membranes by effectively causing flows of an upward flow to act whole the membrane surfaces of the filter membranes. <P>SOLUTION: In the membrane cartridge 51 constituted by arranging the filtering membrane 53 on the surface of the filtering plate 52 and arranging a liquid collecting part 56 communicating with a liquid passing channel 55 between the filtering membrane 53 and the filtering plate 52 in the upper part of the membrane plate 52, the filtering plate 52 has a liquid passing groove 61b with a predetermined pattern constituting the liquid passing channel in the filtering plate surface, the liquid passing grooves 61b do not continue in a linear pattern repeat merging and branching in a vertical direction of the filtering plate 52. <P>COPYRIGHT: (C)2013,JPO&INPIT |
