SEPARATION MEMBRANE ELEMENT, SEPARATION MEMBRANE MODULE, AND MANUFACTURING METHOD OF SEPARATION MEMBRANE ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a separation membrane element, and a separation membrane module using the separation membrane element having flexibility of root parts of the hollow fiber porous separation membranes, causing little breakage of the root part and leakage of liquid and gas in use, being manufactured by dipping terminal parts of the hollow fiber porous separation membranes in resin liquid, followed by formation of a membrane seal part by hardening the resin, and a manufacturing method of the separation membrane element.;SOLUTION: The separation membrane element has the plurality of the hollow fiber porous separation membranes and the membrane seal part bundling the terminal parts. In the separation membrane element, separation membranes using the separation membrane element and manufacturing method of the separation membrane element, the membrane seal part is formed with casting resin, the holes of the hollow fiber porous separation membranes are filled with hole filling resin at a contact part of the hollow fiber porous separation membranes with the membrane seal part, and the casting resin is firmly bonded to the hole filling resin.;COPYRIGHT: (C)2009,JPO&INPIT
