Effect of Pulse Width on Ozone Generation in Pulsed Streamer Discharges

Ozone has been used in treatment of drinking water andwaste water (e.g., deodorization, decolorization, anddisinfection). Though general ozonizers based on silentdischarge or barrier discharge have been used to supplyozone at many industrial situations, there is still someproblem, such as improvements of ozone concentrationand ozone yield.In this work, ozone was generated by pulsed powerdischarge in order to improve the characteristics of ozonegeneration. High electric field with short pulse widthcould accelerate electrons to cause chemical reactions forozone production without accelerating ion. This meanspulsed power discharge could generate ozone without gasheating. It is also known that a pulse width gives strongeffect to the improvement of energy efficiency in exhaustgas processing.[9] In the conference, the effect of pulseduration on ozone generation by pulsed streamerdischarge would be reported
