Document Type and Number:
WIPO Patent Application WO/2024/004743
Kind Code:
A1
Abstract:
The present invention provides a membrane separation system suitable for suppressing the growth of unwanted microorganisms in the interior of a membrane separation device. A membrane separation system 100 according to the present invention comprises a membrane separation device 10. The membrane separation device 10 includes: a pervaporation membrane 11; and a supply space and a permeation space separated by the pervaporation membrane 11. The membrane separation system 100 performs: a membrane separation operation in which the permeation space is decompressed in a state in which a solution S containing a volatile organic compound C is supplied to the supply space, whereby the solution S is separated into a permeated fluid and a non-permeated fluid; and a cleaning operation in which, in a state in which the membrane separation operation is stopped, the solution S is supplied to the supply space to clean the pervaporation membrane 11 with the solution S.
