Description of the system for water ozonizing

The efficiency of the ozone generation described by active power of the discharge element depends linearly on voltage and frequency.

The dependence on active power takes the following form:

f — frequency,

Cd — capacity of dielectric barrier,

Uz — ignition voltage,

Um — amplitude of the supply voltage,

Csz — capacity of the discharge chamber,

Cw — resultant capacity of discharge element.

Higher efficiency reached by increased voltage is limited by break-down strength of the dielectric and therefore the voltage does not usually exceed 50 V. The efficiency of the ozonizer can be improved by the increase of the frequency of the supply voltage. Higher frequency enables to gain required efficiency at lower voltage and thus raise the quality of the discharge elements. The influence of voltage and frequency on the ozonizer is presented in Fig. 1 and Fig. 2 [3]. The relation (1) and Fig. 1 and 2 show that active power is proportional to the frequency; the frequency influences the voltage of the discharge ignition Uz whereas the efficiency of the ozonizer changes less than proportionally.
