<P>PROBLEM TO BE SOLVED: To provide a filter membrane module which is configured to minimize difference in pressure applied to respective parts of a filter membrane. <P>SOLUTION: The filter membrane module 1 includes: a frame 10 of a flat plate shape on a surface of which slit-like water passages are formed; and a filter membrane 21 which is attached onto the surface of the frame. The frame is provided with a suction water collection port 3 to which negative pressure is applied in order to supply to an outside treated water flowed in the water passage after passing through the filter membrane. Further the water passages are formed in recessed shapes at the frame surface and projections are formed between these water passages. The filter membrane is fixed to either a fixed part of the frame at a rim portion side or the projections formed between water passages to divide a space to which negative pressure is applied. <P>COPYRIGHT: (C)2012,JPO&INPIT |
