HOLLOW-FIBER SEPARATION MEMBRANE ELEMENT, HOLLOW-FIBER SEPARATION MEMBRANE MODULE AND MANUFACTURE OF THEM

摘要

PROBLEM TO BE SOLVED: To provide a hollow-fiber separation membrane element, a hollow-fiber separation membrane module, and a method for manufacturing them by which the element and the module can be manufactured without damaging or disconnecting the hollow fiber membranes even if the hollow-fiber membranes have low elongation and easy to be disconnected. ;SOLUTION: A fibrous substance is wound around the outer circumference of bundles of a plurality of hollow-fiber separation membranes to reinforce the membranes and a hollow-fiber separation membrane element and a hollow- fiber separation membrane module are formed by bundling a large number of the reinforced hollow-fiber bundles, so that damage and disconnection of hollow-fiber separation membranes at the manufacturing time can be prevented and the durability can be improved.;COPYRIGHT: (C)2001,JPO
