Improvement of Efficiency of Decolorizing Organic Dye
Using Pulsed Power Discharge by Air Bubbling
Taichi SUGAI, Ayato SUZUKI, Yasushi MINAMITANI and Yoshio HIGASHIYAMA *
(Received August 31, 2007; Accepted February 1, 2008)Water pollution is one of the global environmental issues at present. We are studying water treatment using pulsed
power discharge in water and air mixture. In this paper, water in a pulsed discharge reactor was
injected with large
quantity of air for bubbling. Decololization time of indigo carmine in the treatment by the strong air bubbling is over
15 times faster than that of non-bubbling. As the airflow for the bubbling increased, the decolorization time
decreased. Likewise, as length of the electrode on water increased, the decolorization time decreased. These results
show that more discharge space in air leads to more decreasing of the decolorization time in the water treatment.
Additionally, as size of bubble is made small, the decolorization time decreased. This result shows that large surface
area of air contacting water solution for reaction of active species leads to decreasing of the decolorization time.
