The purpose of this study is to evaluate the effects of underwater non-thermal Dielectric Barrier Discharge Plasma(DBD plasma) on fish farm effluent. This experiment was conducted in the DBD plasma generator, and the voltages given to generate DBD plasma were 11.6 kV and 23.1 kV. The measurement intervals were 0, 1, 5, 10 and 15 minutes. As a result of the experiment, the change in water quality was proportional to the strength of the voltage and the treatment time. At 23.1 kV for 15 minutes, the water temperature was increased to 51.1%, the pH was decreased by 26.2%, the dissolved oxygen was reduced to 50.3%, the chemical oxygen demand was reduced to 19.1% and the suspended solids was decreased 17.9%. NH₄<SUP>+</SUP>-N was decreased by 95.8%, while NO₂<SUP>-</SUP>-N and NO₃<SUP>-</SUP>-N were increased by 851.8% and 170.2%. The total bacteria number contained in the discharge water was removed 100% at 23.1 kV for 15 minute, and the coliform group was sterilized up to 100% at 23.1 kV for 10 minute. The DBD plasma technology was found to reduce the organic pollutants and have high sterilization power against microorganisms in fish farm effluent.
