Document Type and Number:
Japanese Patent JP2017047417
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a separation membrane element capable of reducing pressure loss between separation membrane elements adjacent to each other when connecting a plurality of separation membrane elements in series.SOLUTION: A separation membrane module includes a plurality of separation membrane elements (A) which have the followings (1) and (2) and are arranged in series: (1) a water collecting pipe, (2) a wound body which has a plurality of separation membranes wound around the water collecting pipe, a supply side channel provided between the separation membranes and a permeation side channel provided between the separation membranes, and a connection channel (B) which connects the supply side channel between end surfaces of the wound body. Therein, a ratio S2/S1 of area S2 of the connection channel on a radial direction cross-section of the water collecting pipe with respect to area S1 of the supply side channel on the end surface of the wound body is 75 to 135%.SELECTED DRAWING: Figure 3
