An ozone generator cartridge 60 suitable for a sterilization, decontamination and/or sanitation device. The cartridge comprises a sealable housing 60 for providing a corona discharge, the housing containing at least one power supply unit 64 and at least one inlet 65 for connection to an oxygen or air supply, the cartridge including at least part of at least one ozone conversion cell 63 attached to and extending from an external surface of a wall of the sealed housing, the conversion cell extending into a delivery conduit 52 of a decontamination device that leads to at least one discharge outlet 16.

A sterilization system includes a controller, a transformer including a primary side in communication with the controller and secondary side, an ozone generator in communication with the secondary side of the transformer and the controller, and a power source in communication with the controller, wherein the ozone generator ionizes atmospheric oxygen through the application of corona discharge.

An ozone generator includes one or more electrode pairs each containing two electrodes arranged at a distance of a predetermined gap length and a power source for applying an alternating-current voltage between the two electrodes. In the ozone generator, ozone is produced when a source gas flows at least between the two electrodes and a discharge is generated between the two electrodes. The ozone generator has a discharge space formed between the two electrodes, and the ozone generator satisfies the condition of 0.5<V/f/L wherein V (m/s) represents a flow velocity of the source gas flowing through the discharge space, f (Hz) represents a frequency of the alternating-current voltage, and L (m) represents a length of the discharge space in the main flow direction of the source gas.

An ozone injector device comprising a housing having a water passageway through the housing, an ozone inlet in fluid communication with the water passageway, a corona tube disposed within the housing and in fluid communications with the ozone inlet, and a clearing piston positioned to move into and out of the water passageway towards the ozone inlet, and configured to prevent flow of ozone into the water passageway.

A water circulation system that includes a pipe assembly for in-line mixing of water and ozone is disclosed. The pipe assembly includes a first flow path for water to flow through. The first flow path includes one or more ozone intake ports that are fluidically coupled to one or more ozone output ports of an ozone supply unit. The pipe assembly further includes a second flow path fluidically coupled in parallel with the first flow path. The second flow path includes a control valve that selectively permits a portion of the water to flow through the second flow path to produce a negative pressure in the first flow path so that ozone is drawn into the first flow path through the one or more ozone intake ports and mixed into the water flowing through the first flow path.

Portable ozone generators and methods of use. For example, a hand-held portable ozone generator has: a housing defining an air inlet, an air outlet, and an air channel communicating between the air inlet and the air outlet; a battery; an ozone generator configured to output, during operation, ozone into the air channel at a non-zero rate that is equal to or below 50 mg/hour; and a controller connected to send control signals to the ozone generator in response to user input. In other cases, a plank or slab shaped portable ozone generator is disclosed, with an air inlet and an air outlet located in respective opposed face plates. In one case the unit has no defined base, and every face and side wall of the device forms a ground engaging base, and the unit functions properly regardless of what face or side wall the unit contacts the ground or a horizontal ground surface with.

A dielectric assembly for generating ozone includes a positive electrode, a negative electrode, a dielectric for generating the ozone, and a knob adapted to extend outside of a housing into which the dielectric assembly is to be placed. A system is also provided for sanitizing and deodorizing water, food, surfaces and air including a microbiological reduction filter device having an input connected to a water supply, a venturi injector disposed within a housing and connected to an output of the microbiological reduction filter device which generates ozone and mixes the generated ozone with the water, and an electrode assembly comprising a plurality of electrodes, a dielectric for generating the ozone, and a knob extending outside of the housing. The dielectric in a first embodiment and the entire dielectric assembly in a second embodiment can be removed from the housing and replaced in its entirety by the knob.
