  • ozone generators of industrial extent are widely used in food sector, long-term preservation of agricultural and animal products, textile sector, sterilization of drinking water, providing swimming pools' hygiene, disinfection of city water supplies and purification of industrial waste waters and in accordance with these purposes, an ozone generation is generally required over its lOOg/hour capacity.
  • low- efficiency multiple reactor systems are obtained by connecting each ozone reactor in parallel. Whereas the discharge occurring in the power source -which is used in ther said reaclurs- in Lhe form of threadlike arches leads to low-efficiency, overheating and poor plasma formation.
  • Arc system provided between high voltage and electrodes is the method known as AC Corona plasma reactor and used most commonly in plasma reactor with the purpose of generating ozone.
  • AC Corona plasma reactor a significant part of different power sources consists of a transformer with a secondary circuit of 0.1-50 kV levels operating by 220V - 50Hz mains. Another part thereof is sources generating high voltage only in the form of short-term pulses. Discharges occur in both systems between the electrodes located in the reactor in the form of arches and arc threads.
  • AC Corona plasma reactor there are various methods in the art in order to generate ozone. Using UVA light for low-concentration generation is the first of them.
  • ozone generation is realized in a cheap and easy way usually by means of UV fluorescent lamps and the said method is preferred for small concentrations due to the fact that efficiency of the said method is low.
  • Another method is chemical production method and it is difficult, expensive and has low efficiency. Therefore, it is not preferred too much.
  • Another method is dielectric- barrier discharge method. This method is the most common method used today and its efficiency is relatively high and it is also suitable for high concentration production.
