<p>Provided are a pressure vessel for a membrane element in which the membrane element can be easily mounted, a membrane filtration apparatus equipped with the pressure vessel for a membrane element, and a method for manufacturing a membrane filtration apparatus. A rail (protrusion) 60 is formed on the inner circumferential surface of the pressure vessel 40 in such a manner that a ridge line 61 extends along the insertion direction of the membrane element. Consequently, the membrane element 10 can be inserted into the pressure vessel 40 so as to be in a sliding contact onto the ridge line 61 of the rail 60 formed on the inner circumferential surface of the pressure vessel 40. Therefore, the frictional resistance can be reduced as compared with conventional ways, so that the membrane element 10 can be easily mounted onto the pressure vessel 40.</p> |
