  • Patent number: 9504963
    Abstract: A spiral separation membrane element (1A) includes: a wound body (3) including a separation membrane; a core tube (2) that penetrates the wound body (3) along the central axis of the wound body (3); and a joining portion (4) that joins the wound body (3) to the core tube (2) at at least one end face (3a) of the wound body (3). The joining portion (4) has a holding portion (41) disposed inwardly of the end face (3a) of the wound body (3) and an extending portion (42) formed integrally with the holding portion (41). The spiral separation membrane element (1A) further includes a restraining member (5A) that secures the extending portion (42) to the core tube (2).

  • Patent number: 9061247
    Abstract: A separation membrane module (1A) includes: a tubular pressure container (7); a plurality of separation membrane elements (2) inserted in the pressure container (7) and each having a first end member (3) and a second end member (4); and a sealing member (5A) mounted on one of or both the first end member (3) and the second end member (4) that are adjacent to each other. In a normal condition, the sealing member (5A) is located radially inward of a maximum diameter portion of the first end member (3) and/or the second end member (4) on which the sealing member (5A) is mounted. The sealing member (5A) is deformed due to contact between the adjacent separation membrane elements (2) or due to supply of a pressurized liquid into the pressure container (7), and comes into close contact with an inner circumferential face (7a) of the pressure container (7).
