  • Membrane module apparatus, packaging body, liquid treatment system, steam sterilization method and system constructing method
    Patent number: 10384166
    Abstract: Provided is a membrane module apparatus capable of allowing an aseptic connection member to be applicable to a hollow fiber membrane module and avoiding the need for a user to perform a sterilization treatment. A membrane module apparatus includes: a hollow fiber membrane module to be filled with a liquid during steam sterilization; thermoplastic tubes, being aseptic connection members, for aseptically connecting the membrane module apparatus to another duct; connecting tubes for connecting liquid ports of the hollow fiber membrane module respectively to the thermoplastic tubes; and closure members capable of pinching and closing the connecting tubes. The connecting tubes have heat resistance to the steam sterilization. An expansion member is connected to a liquid port of the hollow fiber membrane module.

  • Device and method for detecting leakage of filter film
    Patent number: 6065329
    Abstract: An apparatus for detecting leakage through a filtration membrane which comprises a gas-supplying source for supplying a gas to one of two spaces formed by partition with the filtration membrane, a gas-detecting device for measuring the degree of leakage of the gas into the other space, and further preventing the undesirable influence of the supplied gas on the gas-detecting device.
