Principles of Ozone Formation

• A high voltage is applied between two
  concentrically arranged electrodes. The
  electrodes are separated from each other by a
  dielectric and two discharge chambers, through
  which gas flows. Some of the oxygen molecules in
  the input gas break down in the electric field
  and immediately attach themselves to free oxygen
  molecules, forming ozone.

Principles of Ozone Formation

• Because ozone is very reactive, it is also
  unstable. It cannot therefore be stored and has
  to be produced where and when it is needed. Ozone
  is produced from oxygen-containing gases in ozone
  generators by means of a silent electrical
  discharge. All industrial-scale ozone generators
  make use of this method.
• The effectiveness of the ozone generation is
  related to a number of factors. Depending on the
  input gas, the strength of the electric field,
  cooling and the design of the ozone generator,
  ozone yields of 1 to 16 percent by weight can be
  achieved in the production gas.
