Abstract:
1. A separation membrane module comprising: a tubular pressure container; a plurality of separation membrane elements each having a separation membrane, and a first end member and a second end member that are disposed so as to sandwich the separation membrane, the plurality of separation membrane elements being inserted in the pressure container in such a manner that the first end members and the second end members are alternately arranged in an axial direction of the pressure container; and a sealing member being annular and mounted on one of or both the first end member and the second end member that are adjacent to each other, the sealing member in a normal condition being located radially inward of a maximum diameter portion of the first end member and/or the second end member on which the sealing member is mounted, wherein the sealing member is deformed due to contact between the separation membrane elements adjacent to each other or due to supply of a pressurized liquid into the pressure container, and thus comes into close contact with an inner circumferential face of the pressure container.
