ABSTRACT:
A system and method for producing an ozone-containing disinfecting cloud includes an enclosure. A pair of atomizing nozzles are affixed to the enclosure in substantially directly opposed relation. Each nozzle produces a spray of ozonated water from compressed gas, ozone, and water and are positioned to direct the sprays toward each other to form a cloud comprising droplets having a size distribution. A portion of the cloud that comprises droplets having a size less than a predetermined limit is expelled from the enclosure. Droplets having a size greater than the predetermined limit remain in the enclosure. The expelled cloud has been found to have a pH lower than a pH of the remaining droplets. The cloud so produced can be used to disinfect an area by directing the cloud to the area desired to be disinfected, which can comprise a surface and/or a space.
