    • Provided is method for concentrating ozone gas the method including the steps of: allowing ozone gas to be adsorbed onto the adsorbent by introducing ozone gas-containing raw material mixed gas into an adsorption vessel (20) that houses an adsorbent for adsorbing ozone gas; reducing a pressure in a concentration vessel (30) in a state where the concentration vessel (30) does not communicate with the adsorption vessel (20), the concentration vessel (30) being configured to be connected to the adsorption vessel (20) so as to be interswitchable between a state where the concentration vessel (30) communicates with the adsorption vessel (20) and a state where the concentration vessel does not communicate with the adsorption vessel (20); and introducing concentrated mixed gas including ozone gas with a higher ozone gas concentration than the ozone gas concentration in the raw material mixed gas into the concentration vessel (30) by desorbing the ozone gas adsorbed onto the adsorbent using a pressure difference between the internal pressure of the concentration vessel (30) and an internal pressure of the adsorption vessel (20) in a state where the concentration vessel (30) having a reduced internal pressure communicates with the adsorption vessel (20) that houses the adsorbent onto which the ozone gas is adsorbed, and delivering the desorbed ozone gas into the concentration vessel (30). Also provided is an apparatus (1) for concentrating ozone gas for implementing the method.

    • Ozone generating apparatus are disclosed. An example ozone generator includes an outer housing defining a first inlet port and a first outlet port, and an inner housing disposed in the outer housing. The inner housing defines a second inlet port and a second outlet port. The example ozone generator also includes a plurality of UV lamps disposed in the inner housing and a lamp ballast for powering at least some of the plurality of UV lamps. The lamp ballast are disposed in the outer housing. Additionally, the example ozone generator includes a blower disposed in the outer housing configured to intake air via the first inlet port and to exhaust air through the second inlet port, and a plurality of springs disposed in the inner housing. Each of the plurality of springs are disposed between one of the plurality of UV lamps and the inner housing.
