AERATION UNIT AND FILTERING APPARATUS COMPRISING THE SAME

摘要

Disclosed is an aeration unit capable of cleaning all the hollow fiber membranes in a filtering apparatus sufficiently and uniformly thereby improving the filtration efficiency and a filtering apparatus comprising the same. An aeration unit of the present invention comprises a plurality of aeration tubes parallel to each other, each of the aeration tubes comprising a first end and a second end opposite the first end; and a first common pipe in fluid communication with the aeration tubes through the first ends of the aeration tubesto provide the aeration tubes with air. The first common pipe is perpendicular to the aeration tubes. The closer to both ends of the first common pipe the aeration tubes are, themore densely the aeration tubes are arranged.
