Title:
SPIRAL-TYPE SEPARATION MEMBRANE MODULE
Document Type and Number:
WIPO Patent Application WO/2017/073279
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a highly reliable membrane module for removing hazardous components without the risk of a supply-source fluid and a concentrated fluid intermixing inside a hollow tube. This spiral-type separation membrane module is characterized in that: a spiral-type separation membrane element is accommodated in a cylindrical container, the spiral-type separation membrane element having a structure in which a laminated body is wound around a porous hollow tube in a spiral shape, a supply-side flow path member being positioned on the supply side of a separation membrane, a transmission-side flow path member being positioned on the transmission side, and the supply-side flow path and the transmission-side flow path being sealed so as not to communicate directly with each other; the cylindrical container has a supply-source fluid inlet, a transmission fluid outlet, and a concentrated fluid outlet; the upstream-side end of the hollow tube is closed off integrally with the tube side surface; and the downstream-side end of the hollow tube protrudes to the outside via the transmission fluid outlet in the cylindrical container.
