A method and system of generating ozone gas. The method comprises receiving a stream of ambient air that includes at least oxygen gas, generating ozone gas based upon applying ultraviolet (UV) irradiation provided in accordance with a wavelength of 185 nanometer (nm) to at least a portion of the oxygen gas, the UV irradiation provided via an optical lamp module powered by a direct current (DC) voltage battery source, producing a modified air stream in accordance with the generating, and exhausting the modified air stream, the modified air stream having a higher concentration of ozone gas as compared with a trace concentration of ozone gas that is constituted in the stream of ambient air.

A distributed sterilizer system for distributing ozone water to a plurality of rooms comprising an ozone generation system for generating ozone from an air supply, a plurality of injection devices for mixing the ozone generated from the ozone generation system with a supply of water to form ozone water and a delivery piping system for distributing the ozone water from the plurality of injection devices into each of the plurality of rooms. The ozone generation system further comprises a centralized oxygen concentrator for providing a supply of oxygen and a plurality of ozone generators for generating ozone from the oxygen supplied by the centralized oxygen concentrator. The distributed sterilizer system also provides a mechanism for distributing ozone directly to a plurality of other rooms.

An air treatment device having a flexible air hose, duct or gooseneck member. The air hose, duct or gooseneck member permits an inlet end thereof to be positioned in proximity to a patient so that a negative pressure can be created around the patient so that air can sucked or vacuumed into the system whereupon it is treated as the air flows through the system.

A method for extracting and capturing airborne aerosol and particulate matters in the air that may be potentially contaminated with harmful bacteria and viruses using a vacuum extraction system; treating the contaminated air by scrubbing it with a biocide solution; filtering the scrubbed air using activated carbon and HEPA filters to remove any residual biocide; and optionally, treating the filtered air with UV-C, ozone, or plasma, before the sterilized air is return to the environment.

The system includes a computer server receiving data representative of the temperature of the cabin and including a database containing, for the aircraft, a predetermined cycle of regulation of the temperature of the air of the cabin; a ground pre-conditioned air unit including: a pre-conditioned air generator and a control module; and a user interface connected to the computer server and transmitting a control signal to the control module; and the control module, upon receiving the control signal, controlling the pre-conditioned air generator, according to the predetermined cycle, which is modulated depending on the data. This system makes it possible to control the temperature of the cabin in real time, so as to correctly disinfect it.
