PROBLEM TO BE SOLVED: To provide a water treatment system where operation control is possible while estimating the stain of a reverse osmosis membrane at a real time.SOLUTION: Provided is a water treatment system comprising: a reverse osmosis membrane 16; a foulant sensor 14 connected in parallel to a treatment water flow passage passed with treatment water fed to the reverse osmosis membrane 16, and in which a part of the treatment water passing through the treatment water flow passage is fed to estimate the degree of the stain sticking to the reverse osmosis membrane 16; and a control part 50 of controlling the feed conditions of the treatment water fed to the reverse osmosis membrane 16 based on the degree of the stain of the reverse osmosis membrane 16 estimated by the foulant sensor 14 during the continuous operation.SELECTED DRAWING: Figure 1 |
