FILTRATION APPARATUS

摘要

An object is to provide a filtration apparatus which can be reduced in size by relatively densely arranging a plurality of filtration modules and in which the efficiency of cleaning the hollow-fiber membranes can be increased. A filtration apparatus according to the present invention includes a plurality of filtration modules, each including a plurality of hollow-fiber membranes, which are arranged in parallel in a vertical direction so as to form a substantially curtain-like shape, and a pair of rod-shaped holding members that secure top and bottom ends of the hollow-fiber membranes; one or more cleaning modules that supply bubbles to the filtration modules from below; and a frame that holds the filtration modules and the one or more cleaning modules. The filtration modules are arranged in parallel and with substantially constant intervals therebetween. A plurality of guide rails that engage with the lower holding members of the filtration modules extend between opposing surfaces of a plurality of frame members that are arranged horizontally in parallel. The one or more cleaning modules preferably have bubble ejection holes disposed between the lower holding members in top view.
