Title:

SEPARATION MEMBRANE UNIT AND SEPARATION MEMBRANE ELEMENT WITH SAME

Document Type and Number:

WIPO Patent Application WO/2011/058778

Kind Code:

A1

Abstract:

A separation membrane unit is provided with two separation membranes (1) which each have a separation active layer (4) formed on one surface of a sheet-like porous base material (3) and which are superposed on each other so that the separation active layers (4) face each other. The two separation membranes (1) are folded multiple times into pleats, and as a result, folds (5) are formed alternately on one side and the other side (top side and bottom side in FIG. 4A) of the two separation membranes (1). As a result of the two separation membranes (1) being superposed on each other so that the separation active layers (4) face each other, the separation active layers (4) are not exposed, and the simple configuration can prevent the separation active layers (4) from being damaged.
