An ozone generator of a gas blow-through type, especially to produce a gas mixture of ozone/air or ozone/oxygen. An ozone producing structural unit in the path of the blown air or oxygen is used as ozone source. The ozone producing structural unit is operated on the principle of alternating current auxiliary electrode cold arc discharge with its capacity increased by limited arc discharge, with an alternating voltage voltage source. This solution does not result in high-temperature arc discharges, thus the fire hazard may be eliminated, and at the same time the device is capable of producing extremely large quantities of ozone. The ozone producing structural unit of the ozone generator is placed in one or more insulating housings/air ducts, placed in a direction parallel to or coaxial to the air blowing direction. Further details of the apparatus are disclosed herein.

An ozone generator includes a discharge chamber; an inlet opening for feeding air into the discharge chamber; an outlet opening for removing ozone from the discharge chamber; and at least two cylindrical electrode sets in the discharge chamber. Each electrode set includes a ground electrode; a high voltage electrode; a dielectric between the ground electrode and the high voltage electrode; the dielectric separated from the ground electrode by a first discharge gap, and the dielectric separated from the high voltage electrode by a second discharge gap. A high voltage power supply provides a voltage impulse to the high voltage electrode of at least 2 kV (at least 5 kV is most cases), and a peak current of at least 1 ampere (at least 4 amperes in most cases). The high voltage power supply provides a dU/dt of the voltage impulse of between 5 kV/sec and 50 kV/sec.

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 portable, personal advanced-oxidation water treatment system based on ozone and a catalyst such as titanium dioxide that can cycle and purify water to make it potable by removing organic contaminants. The unit can be used for long periods of time without having to replenish the active portions. The unit can be carried in a backpack or in a vehicle. Fresh water is typically loaded into the unit, and the unit is cycled until the water is pure enough to drink. A battery is used to produce ozone and to cycle the water through a reaction vessel and can optionally be charged with a small solar panel The unit can also be powered directly from a vehicle.
