The present invention relates to modular ozone-based disinfection systems that generate hydroxyl radicals from gaseous ozone and water vapor using a manganese dioxide treatment module. A sealed, replaceable water cartridge supplies water to an electrochemical ozone generator, producing gaseous ozone for introduction into an airflow path within a housing. An air circulation subsystem directs the ozone-containing airflow across the manganese dioxide treatment module, which catalytically generates hydroxyl radicals and reduces residual ozone to levels safe for human exposure. In some embodiments, a positive temperature coefficient (PTC) heating element preheats airflow to enhance radical production. A controller manages ozone generation, airflow, heating, and operational modes, and may track cartridge usage, transmit data, or enforce geofencing. The modular design supports various water sources, portable or fixed installation, and integration into refrigerated or enclosed spaces, providing safe, on-demand oxidizing treatment of air, surfaces, and water systems while ensuring compliance with exposure limits.

When supplying gas along with liquid to an ejector to generate a gas-dissolved liquid, this prevents the liquid that flows back from the gas intake of the ejector from entering the gas supply system. [Solution] In generating ozonated water as a gas-dissolved liquid using an ozonated water generator equipped with an ejector 1 enclosed in a tank 2, ozone gas is injected as a gas into the flow of water, which is liquid, introduced into the ejector 1 to generate ozonated water. During this process, the water that flows back out from the ozone gas intake of the ejector 1 is stored in the tank 2.
