An attaching/detaching method of an element unit, a demarcation membrane module, and a demarcation membrane element

Japanese Patent JP6164216

B2

An object of the invention is to reduce the costs of members that constitute a separation membrane module and give a separation membrane element an appropriate rigidity and a softness that allows energy of aeration to escape. Another object is to provide a separation membrane module that, at the time of failure occurring on one or more of the membrane elements constituting the separation membrane module, allows the maintenance thereof, that is, the replacement or extraction of the failed one or more membrane elements, to be easily performed. A separation membrane module 21 has an element unit. The element unit comprises: a shaft 9; a plurality of separation membrane elements 1 each including a separation membrane pair having two separation membranes disposed so that permeate-side surfaces of the separation membranes face each other and a water collecting flow path provided between the separation membranes, and a sealed portion that seals the separation membranes at peripheral edge portions of the separation membranes; a suspension portion (8) that suspends the separation membrane elements 1 on the shaft 9; and a water collection nozzle 7 provides communication between the water collection flow path and an outside of the separation membrane elements.
