Abstract
Provided is a pure water production device including a reverse osmosis membrane system having two or more reverse osmosis membranes arranged, in which a detection means for detecting an indicator capable of calculating an effective membrane pressure of a reverse osmosis membrane of the reverse osmosis membrane system is provided upstream or downstream of the reverse osmosis membrane system, and the pure water production device includes a control means for adjusting an effective membrane pressure by controlling a number of reverse osmosis membranes through which water passes in the reverse osmosis membrane system based on a detection value of the detection means.
