Abstract

To provide a water treatment system that can sterilize a reflux line of a reverse osmosis membrane apparatus as well with hot water.SOLUTION: A water treatment system 100 according to one aspect of the present invention comprises: a reverse osmosis membrane apparatus 2 that separates target water into permeable water and membrane concentrated water using a reverse osmosis membrane; a supply line 10 having a supply pump 12, and through which the target water is supplied to the reverse osmosis membrane apparatus 2; a permeable water line 20 through which the permeable water is derived from the reverse osmosis membrane apparatus 2; a membrane concentrated water line 30 through which the membrane concentrated water is derived from the reverse osmosis membrane apparatus 2; a reflux line 40 having a rectification valve 41 for preventing influx from the supply line, and through which some of the membrane concentrated water is refluxed from the membrane concentrated water line 30 to an upstream side of the supply pump 12 of the supply line 10; and a sterilization pump 71 that supplies the supply line 10 with sterilized water that is used for sterilizing the reverse osmosis membrane apparatus 2. At least either of the supply line 10 and the membrane concentrated water line 30 is bent to be nearly concentric with the reflux line 40 at a portion just before or a portion just after a connection point of the reflux line 40.SELECTED DRAWING: Figure 1
