Abstract
Official abstract text for this publication.
The purpose of the present invention is to provide a highly reliable membrane module for removing hazardous components without the risk of a feed-source fluid and a concentrated fluid intermixing inside a hollow tube. The spiral wound separation membrane module is characterized in that: a spiral wound separation membrane element accommodated in a cylindrical container, the spiral wound separation membrane element having a structure in which a laminated body having a separation membrane, a feed-side spacer and a permeation-side spacer is wound around a porous hollow tube in a spiral shape, the feed-side spacer is positioned on a feed side of the separation membrane, the permeation-side spacer is positioned on a permeation side of the separation membrane, and a feed-side flow path and a permeation-side flow path are sealed so as not to communicate directly with each other.
First claim
Opening claim text (preview).
The invention claimed is: 1. A spiral wound separation membrane module, comprising a spiral wound separation membrane element accommodated in a cylindrical container, the spiral wound separation membrane element having a structure in which a laminated body having a separation membrane, a feed-side spacer and a permeation-side spacer is wound around a porous hollow tube in a spiral shape, the feed-side spacer is positioned on a feed side of the separation membrane, the permeation-side spacer is positioned on a permeation side of the separation membrane, and a feed-side flow path and a permeation-side flow path are sealed so as not to communicate directly with each other; wherein the cylindrical container has a feed-source fluid inlet, a permeation fluid outlet and a concentrated fluid outlet; the upstream-side end of the hollow tube is closed off integrally with the tube side surface; the downstream-side end of the hollow tube protrudes to the outside via the permeation fluid outlet in the cylindrical container; wherein the cylindrical container has one permeation fluid outlet at each end; two spiral wound separation membrane elements are accommodated in the cylindrical container; and the downstream-side end of each hollow tube of each spiral wound separation membrane element protrudes to the outside via each permeation fluid outlet in the cylindrical container.
