Beschreibung
Zusammenfassung:	A method for evaluating the performance of a water treatment device having a plurality of main vessels arranged in parallel to each other and having a reverse osmosis membrane for separating water to be treated into concentrated water and permeable water, the method including a specifying step of specifying a main vessel having a highest concentration rate among the plurality of main vessels as a target vessel, and a detecting step of detecting an index of the precipitation ease of scale in the water to be detected having a concentration corresponding to a concentration of concentrated water discharged from the target vessel.
