Abstract
Official abstract text for this publication.
An object of the present invention is to provide a filtration apparatus capable of achieving space-saving of the entire apparatus. A filtration apparatus according to the present invention includes a plurality of filtration modules that each include a plurality of hollow fiber membranes that are arranged adjacent to each other so as to extend in an up-down direction, a washing module configured to supply air bubbles from below the plurality of filtration modules, and a frame that supports the plurality of filtration modules. The washing module includes a plurality of aeration tubes each having a plurality of aeration holes. At least a portion of the frame is a hollow tube through which a gas is supplied to the plurality of aeration tubes.
First claim
Opening claim text (preview).
1 . A filtration apparatus comprising: a plurality of filtration modules that each include a plurality of hollow fiber membranes that are arranged adjacent to each other so as to extend in an up-down direction; a washing module configured to supply air bubbles from below the plurality of filtration modules; and a frame that supports the plurality of filtration modules, wherein the washing module includes a plurality of aeration tubes each having a plurality of aeration holes, and wherein at least a portion of the frame is a hollow tube through which a gas is supplied to the plurality of aeration tubes. 2 . The filtration apparatus according to claim 1 , wherein the hollow tube is disposed so as to extend in an up-down direction. 3 . The filtration apparatus according to claim 2 , wherein the washing module includes a gas-introducing tube in communication with the plurality of aeration tubes, and the hollow tube is in communication with the gas-introducing tube. 4 . The filtration apparatus according to claim 3 , wherein the frame includes the hollow tube as a single hollow tube, and the hollow tube is in communication with one end portion of the gas-introducing tube. 5 . The filtration apparatus according to claim 4 , wherein the frame includes four vertical frame members disposed at four corners of a support structure in plan view, four upper horizontal frame members suspended between upper end portions of the vertical frame members adjacent to each other, and four lower horizontal frame members suspended between lower end portions of the vertical frame members adjacent to each other, and wherein the hollow tube is connected, between a pair of the vertical frame members adjacent to each other, to the upper horizontal frame members and the lower horizontal frame members.
