Ozone Generation
Principle
Besides fluorine, ozone is the strongest oxidizing agent, and if correctly applied, able to
contribute enormously to improve the condition of our life and environment. When compared
to other oxidizing agents, the advantage of ozone is that, aside from the reaction products,
only oxygen develops - no toxic residue must be disposed. Ozone has been known for more
than 100 years, and has proven itself as an environmentally friendly oxidizing agent in many
areas of application.
Ozone is technically produced through silent electrical discharge from oxygenic feed gases,
typically air or oxygen, by special ozone generators.
During the ozone synthesis process oxygen molecules are split through the supply of energy.
The resulting oxygen atoms react with oxygen molecules to form ozone, whereby heat is
released which has to be dissipated by cooling.
Ozone formation takes place between two electrodes, which are isolated from each other by
a dielectric made of glass or ceramic and by a small gap. A high voltage, middle frequency,
unilaterally grounded alternating current is applied to the electrodes. The oxygenic gas flows
through the gap, resulting in ozone generation in the electrical field.
