PRESSURE VESSEL FOR MEMBRANE ELEMENT, MEMBRANE FILTRATION APPARATUS EQUIPPED WITH THE PRESSURE VESSEL FOR MEMBRANE ELEMENT, AND METHOD FOR MANUFACTURING MEMBRANE FILTRATION

摘要

membrane element is provided for the membrane element is a pressure vessel which can be easily mounted . Membrane and the membrane filtration unit is also provided with a pressure vessel for the element , a method of manufacturing a membrane filtering device. Rail ( protrusion ) 60 is on the inner circumferential surface of the pressure vessel 40 , a ridge 61 is formed in a direction extending along the insertion direction of the membrane elements . As a result, the membrane element 10 can be inserted into the pressure vessel 40 is in sliding contact manner to the ridge 61 of the rail 60 formed on the inner circumferential surface of the pressure vessel 40 . The membrane elements as compared with the prior art 10 can be easily mounted in the pressure vessel (40). ;
