  • Separation membrane module and repairing method thereof
    Patent number: 11065584
    Abstract: An object of the present invention is to provide a separation membrane module in which an end member is prevented from coming out even at the occurrence of a reverse pressure or the like. The invention relates to a separation membrane module which is equipped with a cylinder-shaped housing and a tubular separation membrane and which takes out a fluid which has permeated the tubular separation membrane. An end pipe is connected to one end portion of the tubular separation membrane; the end pipe is supported by a support plate which is disposed so as to traverse the housing; and an end plug is connected to the other end portion of the tubular separation membrane. The separation membrane module is further equipped with a coming-out preventive member.
