Abstract: A sanitizer system has an ultraviolet (UV) lamp, a UV transparent tube and Venturis that that draw ozonated air from near the UV lamp and mix the ozonated air with water traveling through the UV transparent tube while UV light breaks down ozone in the UV transparent tube into free radicals and other ozone decomposition products. Additional ozone can be introduced into what after it passes through the UV transparent tube.

Abstract: A method for dispensing a sanitizing composition comprising a carrier fluid involves passing a carrier fluid under pressure through a nozzle and a chamber mounted to the nozzle. The chamber receives the carrier fluid from the nozzle and has an opening on an opposite side from the nozzle through which the carrier fluid exits the chamber. Ozone is provided to an interior of the chamber in the presence of the carrier fluid, and is irradiated with ultraviolet radiation as the carrier fluid and the ozone pass through an interior of the chamber.
