Abstract: A multi-use sanitization system is disclosed which includes one or more containers in fluid communication with other system components. Components of the system include an ozone contacting device, such as a vortex-venturi or a sparger, for incorporating ozone into a liquid, an ozone generator to provide ozone to the vortex-venturi, a fluid transfer valve to allow simultaneous flow of liquid into and out of the container, and a pump to promote fluid flow through the system. Optionally, a gas-liquid separator with an optional integral gas release valve, an ozone destructor, an oxidation-reduction potential ozone sensor, or a pour-through type pre-filter may be incorporated into the system.

Abstract: A removable disposable air dryer cartridge is provided for a small enterprise water ozonation system. The cartridge includes an air inlet to receive atmospheric air, a desiccant material to remove moisture, and a dry air outlet for interfacing with the ozonation system to provide dry air to an ozone generator. This facilitates better ozonation of water in the system, since dry air reacts better in an ozone generator, achieving higher concentrations of ozone gas, thus resulting in a better “kill rate” when ozonated water is applied to bacteria. The air dryer can be provided as a chamber of a combined air dryer and water filter cartridge, the other chamber being a water filter chamber having a water filter for extracting large particles of material from the water stream in order to prevent damage to the system.

Abstract: A drinking water pitcher is provided including an upper reservoir and a lower reservoir, and preferably a filter or filter housing. The upper and lower reservoirs are removably mated with one another. The interface between the upper and lower reservoirs restricts or prevents water flow from the upper reservoir to the lower reservoir unless the reservoirs are properly mated/seated together, such as by a water restriction means in the upper reservoir. In another aspect, a drinking water purification system is provided including a base unit and a drinking water pitcher. The drinking water pitcher includes an upper reservoir, a lower reservoir and preferably a filter or a filter housing. The base unit can include a sanitization means. The upper and lower reservoirs are removably mated with one another, and the upper reservoir can be removably mated with the base unit. A method of purifying water is also described.

Abstract: An ozonated water dispenser allows a user to kill bacteria and microbiological organisms on their hands or other objects. The dispenser includes a reservoir, a pump, and an ozonated water delivery means downstream from the pump to dispense pressurized ozonated water in a fine mist. The delivery means includes a mister and a control valve, such as a solenoid, to restrict water flow in a water line to build up water pressure between the pump and the control valve to overcome the mister's cracking pressure. A water ozonation means is provided downstream from the ozonated water delivery means, and in communication with an inlet of the reservoir to recirculate water. This dispenser uses regular tap water and can be employed as an alternative to a sanitizing gel, or when use of a gel is not practical or desirable, such as for sanitizing fresh produce after its purchase.
