| Zusammenfassung: | A method for operating a desalting device that has a first desalting device and a second desalting device, said method comprising: a normal operation step for supplying to-be-treated water to the first desalting device so as to separate the to-be-treated water into first concentrated water and first desalted water, and supplying the first concentrated water to the second desalting device so as to separate the first concentrated water into second concentrated water and second desalted water; and a recovery operation step for supplying the to-be-treated water to the first desalting device so as to separate the to-be-treated water into the first concentrated water and first permeated water, and passing dilute water having a lower concentration than the first concentrated water through the second desalting device so as to recover desalting performance of the second desalting device. |
