Low frequency ozone generator

A method of operating an ozone generator apparatus, said ozone generator apparatus comprising an ozone generator unit comprising:

• a high voltage electrode unit;
• a first and second dielectric element;
• and
• a first and second earth electrode;
• wherein said high voltage electrode unit is located between said first and said second dielectric element, and
• wherein said generator unit is configured to be operated at an operational frequency range between 30 and 40 kHz;
• and the apparatus further comprises a low frequency, high voltage AC power supply being a transformer assembly, configured to provide between 50 and 800 Watts at a frequency between 30 and 40 kHz to the ozone generator unit, said method comprising operating said ozone generator apparatus at a frequency between 30 and 40 KHz.
