Abstract

Official abstract text for this publication.

A filter unit according to the present invention includes a plurality of filtration modules and a plurality of air bubble generation modules. Each filtration module includes a plurality of hollow fiber membranes extending in an up-down direction and arranged side by side in a curtain shape and a pair of holding members to which top and bottom ends of the hollow fiber membranes are fixed. The air bubble generation modules discharge bubbles toward the hollow fiber membranes. The filtration modules are arranged in parallel at intervals. each air bubble generation module has a discharge port that is disposed between lower holding members of a pair of adjacent filtration modules and above bottom ends of the lower holding members.

First claim

Opening claim text (preview).

1 . A filter unit comprising: a plurality of filtration modules which each include a plurality of hollow fiber membranes extending in an up-down direction and arranged side by side in a curtain shape and a pair of holding members to which top and bottom ends of the hollow fiber membranes are fixed; and a plurality of air bubble generation modules that discharge bubbles toward the hollow fiber membranes, wherein the filtration modules are arranged in parallel at intervals, and wherein each air bubble generation module has a discharge port that is disposed between lower holding members of a pair of adjacent filtration modules and above bottom ends of the lower holding members. 2 . The filter unit according to claim 1 , wherein the discharge port of each air bubble generation module is at a horizontal level close to a horizontal level of top ends of the lower holding members of the pair of adjacent filtration modules. 3 . The filter unit according to claim 1 , wherein the discharge port of each air bubble generation module is formed in an oblong shape whose longitudinal direction is a direction parallel to the filtration modules. 4 . The filter unit according to claim 1 , 2 , or 3 , wherein each air bubble generation module is configured to discharge the bubbles intermittently. 5 . The filter unit according to claim 1 , wherein each air bubble generation module has gaps between the air bubble generation module and side surfaces of the lower holding members of the pair of adjacent filtration modules. 6 . The filter unit according to claim 5 , wherein each air bubble generation module is spaced from the lower holding members of the pair of adjacent filtration modules.
