| Zusammenfassung: | To provide a method for operating a membrane separation device that can maintain cleanliness in a system and separation performance of membrane separation means.SOLUTION: Provided is a method for operating a membrane separation device configured to be capable of changing flowing directions of permeable water and concentrated water in a membrane separation module for supplying raw water and separating the raw water into permeable water and concentrated water. The method for operating the membrane separation device includes: a water sampling step of sampling permeable water from a permeable water outlet of the membrane separation module; and a cleaning step of cleaning the membrane separation module by draining raw water from a concentrated water outlet of the membrane separation module.SELECTED DRAWING: Figure 3
