<p><P>PROBLEM TO BE SOLVED: To provide a pressure vessel for membrane elements enabling an easy filling of membrane elements, and also to provide a membrane filtration device provided with the same and a method of manufacturing the membrane filtration device. <P>SOLUTION: A rail (protrusion) 60 is formed on an inner peripheral surface of the pressure vessel 40 in such a manner that a ridge line 61 extends along an insertion direction of the membrane element, by which the membrane element 10 can be inserted into the pressure vessel 40 in a sliding contact with the ridge line 61 of the rail 60 formed on the inner peripheral surface of the pressure vessel 40. Accordingly, since a friction resistance can be decreased compared with the conventional constitution, the membrane element 10 can be loaded easily to the pressure vessel 40. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
