| description | The invention relates to a fresh water generation system which controls operation of the system via efficiently utilizing surplus power of generated power. More specifically, when the surplus power 22 of a natural energy power generator 20 is small, only a brackish water RO device 14 is operated to generate produced water having a low salinity concentration from intermediate water supplied from middle water tanks 12 and 13, whereby the produced water is stored in a produced water tank 14c. When the surplus power 22 is middle, only a salt water RO device 1 la is operated to generate intermediate water having a relatively low salinity concentration from raw water having a high salinity concentration supplied from a raw water tank 16. Then, the intermediate water is stored in the middle tanks 12 and 13. Further, when the surplus power 22 is large, both brackish water RO device 14 and salt water RO device 11 a are operated. In this case, while storing intermediate water in the middle tanks 12 and 13, produced water is generated from the intermediated water thus stored in the middle tanks 12 and 13. Then, the produced water thus generated is stored in the produced water tank 14c. Herein, a controller 15 controls operation change between the brackish water RO device 14 and salt water RO device 11 a corresponding to the fluctuation of the surplus power. |
