HOLDING STRUCTURE OF MEMBRANE CARTRIDGE

摘要

PROBLEM TO BE SOLVED: To provide holding structure of a membrane cartridge which can hold respective planar membrane cartridges with stable spaces. SOLUTION: In a membrane separating device 21 which is dipped in a treating bath, is arranged above an air diffuser 23 and holds in parallel a plurality of planar membrane cartridges 22 arranged in a vertical direction, slits 41 for holding both side edges of the respective planar membrane cartridges 22 are formed at inner flanks facing each other and a pair of guide faces 42 which are symmetric to a shaft center of the slit 41 and have downward incline are formed at a bottom part of the slit 41 supporting a lower end edge of the planar membrane cartridge 22.
