Abstract: An apparatus has a tank with an interior for containing water, a nozzle for directing ozonated water out of the spray apparatus, and an electrolytic cell located between the nozzle and the tank. The electrolytic cell is configured to ozonate water as the water flows from the tank to the nozzle. The apparatus also includes a power source for providing electric potential to the electrolytic cell. The tank, nozzle, and electrolytic cell all are part of a single spray bottle or dispenser (e.g., like a soap dispenser).

Abstract: An apparatus has a hub including a water inlet for receiving source water, a water outlet for discharging ozonated water, and an interface between the water inlet and the water outlet. The apparatus also has a cartridge including an electrolytic cell for ozonating the source water. The electrolytic cell has a cathode, an anode comprising diamond, and a membrane between the cathode and the anode. The electrolytic cell is configured to flow source water through both the cathode and the anode. The cartridge further includes at least one cartridge port for removably coupling with the interface on the hub. The at least one cartridge port and the interface are configured to flow source water from the hub into the electrolytic cell and to flow ozonated water from the electrolytic cell into the hub.

Abstract: A system and method for disinfecting contact lenses produces ozone from the water in which the contact lenses are submerged, thus avoiding the need to supply ozone from an external source. Ozone is created by an electrolytic cell including a diamond electrode, which is submerged in the water with the contact lenses to be disinfected. The diamond electrode may include a number of fingers, and may be fabricated from a diamond blank.
