Beschreibung
Zusammenfassung:	A method of sterilizing a separation membrane module using water vapor includes: a liquid supplying step of supplying a liquid having a boiling point of 80° C. or higher at atmospheric pressure to a secondary side of the separation membrane module such that a filling ratio of the liquid in a space surrounded by a filtration portion of a separation membrane is 70% or more, the filtration portion being used for filtration; a liquid sealing step of isolating the secondary side of the separation membrane module such that the filling ratio of the liquid supplied to the secondary side in the liquid supplying step is 70% or more; and a sterilization step of sterilizing the separation membrane module by supplying water vapor to a primary side of the separation membrane module while the secondary side of the separation membrane module is isolated.
