How is Ozone Produced

There are basically two methods of producing ozone:

  • Corona Discharge
  • Ultra-violet

Corona discharge creates ozone by applying high voltage to a metallic grid sandwiched between two dielectrics. The high voltage jumps through the dielectric to a grounded screen and in the process, creates ozone from oxygen present in the chamber. This also occurs naturally during lightning storms.

Ultra-violet (UV) light creates ozone when a wavelength at 254 nm (nanometers) hits an oxygen atom. The molecule (O2) splits into two atoms (O) which combine with another oxygen molecule (O2) to form ozone (O3). This also occurs naturally through the sun rays.
