Zusammenfassung:A scale detection device of a concentrating device comprises: a reverse osmosis membrane device 13 that is a concentrating device including a reverse osmosis membrane 13a, which is a filtering membrane for concentrating salt in a water to be treated 11, containing at least calcium sulfate to obtain reclaimed water 12; and a scale detection unit 15 disposed in a branched line L14 branched from a concentrated water line L13 discharging concentrated water 14 having a high concentration of salt, the scale detection unit further concentrating the salt in the concentrated water 14 to obtain reclaimed water for detection 16, and including a detection membrane 15a detecting the absence or presence of scale component deposition in the concentrated water 14.
