ABSTRACT:
A spiral membrane module where membrane elements are easily connected to each other and the connection thereof is prevented from being loosened. The spiral membrane elements (20) are each formed in multiple layers by winding membranes and channel materials around a center tube (3) having holes and are received in a pressure vessel (10) such that they are connected in series with connection mechanisms (J) placed between the membrane elements (20). Each connection mechanism (J) has a movable member (M) installed at either the upstream side end part or the downstream side end part of each membrane element (20) and having an engagement part (9d) engageable with the other of the upstream side end or the downstream side end. The movable member (M) has a contact part (9c) coming into contact with the inner wall (10a) of the pressure vessel (10) and locking the engagement by the engagement part (9d).
