Title:
METHOD FOR PROCESSING SEPARATION MEMBRANE COMPOSITE, AND PROCESSING APPARATUS FOR SEPARATION MEMBRANE COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2023/037886
Kind Code:
A1
Abstract:
This method for processing a separation membrane composite includes a step of preparing a separation membrane composite comprising a porous support and a separation membrane provided on the support (step S11), and a step of causing a washing fluid comprising supercritical or subcritical carbon dioxide having a density of 600-1000 kg/m3 to contact the separation membrane of the separation membrane composite (step S13). This enables removal of organic compounds adsorbed onto the separation membrane, and appropriate restoration of the membrane performance of the separation membrane.
