Abstract

This paper presents the development of an underwater plasma for wastewater treatment. A treatment reactor made of acrylic with multiple stainless-steel rods as the cathode electrode and stainless-steel plate as the ground was used. To find the suitable frequency for treatment, 25 kV pulse high voltage with the adjustable frequency of 20 kHz, 40 kHz, and 60 kHz, was applied to the cathode electrode inside the treatment reactor for generating plasma discharge. The quality of treatment process was evaluated by standard levels of the Biological Oxygen Demand (BOD) and the Chemical Oxygen Demand (COD). By the treatment results, it was found that 25 kV pulse high voltage with 20 kHz frequency was more suitable for wastewater treatment when compared with the other two frequencies due to the faster reduction in COD and BOD values were measured.
