CERAMIC MEMBRANE MODULE AND METHOD FOR REMOVING CONTAMINANT ON MEMBRANE SURFACES OF CERAMIC MEMBRANE MODULE

摘要

PROBLEM TO BE SOLVED: To provide a ceramic membrane module capable of easily and sufficiently removing the contaminant adhered to membrane elements.;SOLUTION: The ceramic membrane module 1 is constituted by providing an element assembly 3 for filtering water to be treated in a casing 2. The element assembly 3 is formed by bundling and fixing a plurality of the membrane elements 6 made of ceramic having a straight tube shape closed at its leading end. An air diffuser 19 for ejecting air to vibrate the membrane elements 6 is provided in the casing 2. The air diffuser 19 is provided in the casing 2 and equipped with a plurality of air diffusion pipes 20a and 20b having a large number of air diffusion holes 23 and a supply pipe 21 for supplying air to the air diffusion pipes 20a and 20b.;COPYRIGHT: (C)2004,JPO
