In this study, we investigated a water treatment method spraying the droplets of wastewater into pulse discharge space. The water treatment was carried out by applying voltage with different pulse widths to determine the optimum pulse width, and the optimum pulse voltage determined on the basis of the results of the study was analyzed. The rise time of the voltages with pulse widths of 40, 60, and 80 ns was about 12, 19, and 32 ns, respectively, and the discharge current in the case of the faster rise time was higher. The number of streamer discharges is believed to increase with a decrease in the rise time. The energy efficiency in the case of the pulse width of 40 ns is higher than that in the case of the other pulse widths. This is because almost all of active species are generated by early streamer discharge, and longer discharging time by longer pulse width makes more ineffectual energy by thermal loss. These results show that the pulsed voltage of faster rise time and shorter pulse width is optimum for the treatment.
