Department of Environmental Science, Catholic University of Daegu, Daegu, Korea*Faculty of Liberal Education, Daegu University, Daegu, KoreaABSTRACT Objectives: This experiment was carried out to elucidate the effect of discharged water on the disinfection ofPhytophthora capsici and evaluate the water characteristics.Methods: The dielectric barrier discharges (DBD) plasma reactor system used in this study consisted of a plasmacomponent [discharge, ground electrode and quartz dielectric tube], high voltage source, and air supply. Theeffects of water characteristics such as pH, ORP and conductivity and the disinfection effect of discharged waterwere investigated. Results: Experimental results showed that in the process of discharge, the pH decreased, whereas ORP andelectric conductivity increased. When the discharge time was 30 min, Phytophthora capsici of 2.94 log wasdisinfected within 300 seconds. Disinfection performance of stored discharged water was maintained for threedays; however the disinfection effect vanished after five days. When Phytophthora capsici was injected into thedischarged water, the disinfection effect decreased after two days.Conclusions: It is considered that the main disinfection parameters of the discharged water were chemicallyactive species such as H
