PRESSURE VESSEL FOR MEMBRANE ELEMENT, MEMBRANE FILTRATION APPARATUS EQUIPPED WITH THE PRESSURE VESSEL FOR MEMBRANE ELEMENT, AND METHOD FOR MANUFACTURING MEMBRANE FILTRATION
摘要
<p>Provided is a pressure vessel for membrane element wherein a membrane element can be loaded easily. Also provided are a membrane filtration apparatus equipped with the pressure vessel for membrane element, and a method for manufacturing a membrane filtration apparatus. A rail (protrusion) (60) is formed on the inner circumferential surface of a pressure vessel (40) in such a manner that a ridge line (61) extends along the inserting direction of the membrane element. Consequently, a 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 circumferential surface of the pressure container (40). Since frictional resistance can be reduced when compared with conventional configurations, the membrane element (10) can be loaded easily onto the pressure vessel (40).</p>
