The IOA is a not-for-profit educational association which performs its information-sharing functions through sponsorship of international symposia, seminars, publications, and the development of personal relationships among ozone specialists throughout the world. Towards achieving this goal, IOA has conducted a wide range of programs covering such fields as:
  • Generation of ozone from air or oxygen by corona discharge or by ionizing radiation
  • Mass transfer of ozone into water and wastewater
  • Chemical reactions of ozone for commercial organic syntheses
  • Drinking water treatment for disinfection and for oxidation of pollutants
  • Ozone treatment for preservation of fruits and for food processing
  • Stratospheric reactions of ozone
  • Development of reliable analytical procedures for ozone
  • Materials of construction for ozone use
  • Ozone safety and health effects

Membership participation in IOA programs is conducted through one of three regional groups. All members in North, Central and South America receive their membership services from and belong to the Pan American Group [PAG].
