Effect of pulse width on generation of ozone by pulsed streamer discharge

Ozone has been used in treatment of drinking water and waste water (e.g., deodorization, decolorization, and disinfection). Though general ozonizers based on silent discharge or barrier discharge have been used to supply ozone at many industrial situations, there is still some problem, such as improvements of ozone concentration and ozone yield. In this work, ozone was generated by pulsed power discharge 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 discharge 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.[9] In the conference, the effect of pulse duration on ozone generation by pulsed streamer discharge would be reported.
