Abstract

The present invention provides a membrane separation system suitable for suppressing a decrease in a content of an organic compound in a permeated fluid. A membrane separation system of the present invention includes a membrane separation device that has a separation membrane, a feed space and a permeation space. When an aqueous solution containing a volatile organic compound is supplied to the feed space and the permeation space is decompressed, the separation membrane separates the aqueous solution into a permeated fluid having a content of the organic compound higher than that in the aqueous solution and a non-permeated fluid having a content of the organic compound lower than that in the aqueous solution. The membrane separation system performs a pressurizing procedure that increases a pressure in the permeation space when at least one condition selected from the group consisting of conditions (A1) to (A3) is satisfied.
