SPIRAL MEMBRANE MODULE

摘要

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