ABSTRACT
One of the most effective ways to produce ozone is to use Dielectric barrier discharge plasma (DBDP). Various geometric configurations can be used to produce ozone. However, it is necessary to develop a reactor to produce medical ozone. Medical ozone can be produced using Double DBD reactor with an oxygen source. The aim of this paper is to carry out an experimental analysis of ozone concentrations which produced using DDBD reactor. The reactor used cylindrical- cylindrical electrode configurations made from copper mesh. The high AC voltage was applied in the range between 0,5 to 3,2 kV and the frequency of 50 Hz. Oxygen (O2) is used as input gas source with several variations in flow rates from 0,2 to 1 liter/min. The results show that air flow rate input and voltage can affect ozone concentration. Ozone concentration can be increased by increasing the voltage or decreasing the flow rate. The results also showed that DDBD with this configuration could produce medical ozone concentration from 24 – 768 ppm which could be applied further in the medical field.
