Patent attributes
Ultraviolet irradiation of liquids for purposes of sterilization, disinfection, cleaning and/or treatment. A liquid collection reservoir can receive an inflow of a liquid. A filtering unit can filter the inflow of liquid received by the liquid collection reservoir. A liquid chamber stores the liquid. Ultraviolet light emitting sources located about the liquid chamber irradiate the liquid in the liquid chamber with ultraviolet light. A control unit, operatively coupled to the ultraviolet light emitting sources, controls the irradiation of the liquid in the liquid chamber with the ultraviolet light emitting sources. The control unit is configured to control an intensity and a duration of the irradiation as a function of time that the liquid is stored in the liquid chamber and the amount of the liquid that is in the liquid chamber.
