DEVICE FOR PRODUCING DESALTED WATER AND METHOD OF PRODUCING DESALTED WATER

摘要

PROBLEM TO BE SOLVED: To provide a device for producing desalted water and a method of producing desalted water which can satisfactorily maintain the quality of treated water in the production of a desalted water using a liquid passage type electric double layer capacitor. SOLUTION: This device for producing the desalted water is provided with the liquid passage type electric double layer capacitor 2, a drawing path 16 which draws the treated water from the liquid passage type electric double layer capacitor 2 to the outside of system and a return path 3 which returns the treated water to the upstream side of the liquid passage type electric double layer capacitor 2.
