1 INTRODUCTION
The ozone is an active modification of the oxygen. It has clear blue color and spicy odor, it is more soluble in water and much more active than the oxygen, it is considered the more powerful oxidant over the earth and it has a lot of applications mainly in sanitation, salubrity and contamination. Due to its chemical properties, it is used as a disinfectant and germicidal. It is employed in air and residual water treatment, deodorization, oxidation process, dental medicine, etc. An important property of the ozone is the absence of toxic substances as a result of its application to disinfect water or other substances, by this reason is commonly used by purification and deodorization industry. The principle of operation of ozone generator consists to apply a high voltage between two parallel plaques with air inside, the high voltage produces the phenomenon know as silent discharge or corona effect. The silent discharge produces ultraviolet radiations that break the oxygen molecule producing ozone. It is important to avoid the arc discharge to maintain the silent discharge, which is obtained adding a dielectric between the air gap and one of the electrodes.
