Abstract:
A water treatment system, comprising:a source of water to be treated; an ultraviolet sterilizer unit operable for applying ultraviolet radiation to said water; a first electrochemical precipitator selectively operable to precipitate minerals in the ultraviolet radiation treated water; a heating device for heating a first portion of said ultraviolet radiation treated water received from said precipitator to a superheated temperature for killing bacteria; a blending device for tempering the heated first portion of treated water with a second portion of said ultraviolet radiation treated water to obtain a blended treated water having a desired temperature; and a recirculating loop including a temperature-responsive valve set to the same temperature as the temperature of said blended water for providing constant recirculation of at least a portion of said blended treated water to said heating device.
