Abstract
This paper details how high-voltage pulsed discharge was generated in water with different types of bubbling gases as well as no gas in a reactor with a point-mesh electrode configuration. Acid orange 7 organic dye solution was treated as wastewater sample to elucidate chemical efficiency of bubbling gas types in discharge reactor. Experimental results showed that, oxygen bubbling gas effectively removed 84.35% of acid orange 7, while corresponding removal rates were 70.40%, 64.67%, 58.36% and 50.81% with argon, air, nitrogen and with no bubbling gas, respectively. Our research clarifies that chemical efficiency of the discharge reactor is significantly influenced by bubbling gases. A magnetic compression pulsed power modulator at 25kV, 100pps was used as a high voltage pulse source to initiate discharge in reactor.
