Improved Single Barrier Ozone Chamber

Abstract

There have been many studies regarding ozone generation using Dielectric Barrier Discharge (DBD) method at atmospheric pressure in various conditions such as variations in gap distance, dielectric materials, electrode settings, gas flow rate, and perforated aluminum of configurations. However, the current study is based on our previous work. This has been intended to improve the ozone chamber design in order to reduce gas leakage as well as to enhance ozone concentration. Perforated aluminum electrodes were arranged on both the cathode and anode sides (double perforated) with an electrode area of 97.38%. The highest ozone concentration of 2002.37 ppm was obtained at 8 kVrms. The obtained ozone concentration in the current work is higher than the previous one, at 6 kVrms applied voltage. A 29.41% enhancement in ozone concentration was obtained. This showed that the improvement on chamber design and electrode configuration contributed to the ozone concentration. Based on these results, there is a possibility to increase the ozone concentration by raising the applied voltage as long as the stability can be achieved.
