Zusammenfassung:Provided is a method for evaluating performance of a water treatment device provided with a plurality of main vessels that are arranged in parallel to each other and that each have a reverse osmosis film for separating to-be-treated water into concentrated water and permeate water, the method comprising: a specification step (S1) for specifying, as a target vessel, a main vessel having the highest concentration rate among the plurality of main vessels; and a detection step (S2) for detecting an index regarding the likelihood of scale precipitation to-be-detected water that has a concentration corresponding to that of the concentrated water discharged from the target vessel.
