Comparison Double Dielectric Barrier Using Perforated Aluminium for Ozone Generation

Abstract

Ozone generation has widely known may replace chlorine compounds in various applications including wastewater treatment, polluted air processing, antimicrobial, bacterial inactivation, semiconductor oxidation, and serve as disinfectan. This study mainly focuses on comparison of different dielectric materials performances using perforated aluminium to obtain high concentrated ozone. Perforated aluminium with sharp edges used for ozone generation as electrode. Dielectric barrier discharge (DBD) using glass and 96% alumina ceramic have been chosen for limiting discharge current due to its low thermal conductivity and low dielectrics loss when high breakdown voltage occur. Double dielectric barrier using perforated aluminium has been observed using 96% alumina and quartz glass, both within 2 mm thickness. Ozone concentration of alumina ceramic dielectric for 0.5mm space gap was higher than quart glass. However, for 1mm space gap, ozone concentration using quart glass was higher than alumina ceramic. These results lead to optimum condition for DBD using alumina ceramic is not more than 0,5mm space gap.
