Operating method for separation device

Abstract

An operating method for a separation device is an operating method for a separation device including a separation membrane, the separation device including: a first flow path to which a mixture is to be supplied; and a second flow path through which a substance that has permeated through the separation membrane is allowed to flow. The operating method includes a step of supplying the mixture to the first flow path so that the mixture flowing through the first flow path has an average Reynolds number of less than 2,000.
