ABSTRACT

Double Dielectric Barrier Discharge (DDBD) generator is a reactor that is considered more qualified as an ozone reactor for medical applications because there is space between two barriers that function as a place for the flow of pure oxygen. Research on optimization of medical ozone production with Double Dielectric Barrier Discharge (DDBD) technology with spiral-spiral electrode configuration has been carried out. The purpose of this study is to obtain the optimum dose of ozone for applications in the medical field. Variations in the number of coils on electrodes (N), namely 30, 40, 50 and high voltage AC used with voltage variations from 0.5 to 2.3 kV and flowrate variations between 0.2 to 1 L/min with 0.2 intervals. The frequency used is 30 Hz. The results showed that the higher the voltage with a constant flow rate, the higher the current produced so that the ozone concentration obtained was also higher. However, the more the number of turns with a constant voltage, the smaller the resulting concentration. In the configuration of the number of coils, the ozone dosage produced is between 67.2 to 537.6 mg.
