<p>A water desalting apparatus which comprises a controlling device which, when the electric power generated by a source such as a solar cell is reduced, stops the supply of electric power to individual motors according to the predetermined preferential ranking so as to maintain smooth operation; a raw water flow rate controller which controls the flow of the raw water supplied to an evaporating device so that a heating medium supplied to an evaporating device has a given or lower temperature; and a concentrated raw water storage tank for storing a raw water concentrated by generating steam and a stored amount measuring device for concentrated raw water for measuring the amount of the concentrated raw water in the concentrated raw water storage tank, wherein the concentrated raw water is used as the cooling water for use in a condenser for the steam from the raw water and, when the stored amount of the concentrated raw water is lower than a given amount, raw water is supplied in advance to the evaporating device by the raw water supplying device and the raw water having been passed through the evaporating device is supplied to the concentrated raw water storage tank so that a given storing amount is maintained. The water desalting apparatus can be appropriately controlled in accordance with the conditions wherein it is operated and be used for desalting with good efficiency.</p> |
