Effect of Pulse Width on Ozone Generation in Pulsed Streamer Discharges

Summary form only given. Ozone has been used in treatment of drinking water and waste water (e.g., deodorization, decolorization, and disinfection). Though general ozonizers based on silent discharges or barrier discharges have been used to supply ozone at many industries, there is still some problems, such as improvements of ozone concentration and ozone yield. In this work, ozone is generated by pulsed power discharges in order to improve the characteristics of ozone generation. High electric field with short pulse width could accelerate electrons to cause chemical reactions for ozone production without accelerating ion. This means pulsed power discharges could generate ozone without gas heating. It is also known that a pulse width gives strong effect to the improvement of energy efficiency in exhaust gas processing. In the conference, the effect of pulse duration on ozone generation in pulsed streamer discharges would be reported.
