This paper presents the elimination of eukaryotic microorganisms in wastewater using high-frequency and high-voltage electric field. The principle and method for eliminating this group of microorganisms are to apply the principle of generating a high-voltage and high-frequency electric field to a switching circuit to supply DC voltage through a flyback transformer. After passing through the flyback transformer, it causes the voltage to rise between 1-30 kV and the frequency to rise between 1-30 kHz to supply a set of designed electrode chamber mechanism. This mechanism is phenomenal in coronal conditions to be used for the elimination of eukaryotic microorganisms in wastewater. The research has been conducted on several issues, including the testing of control circuits, the operation of mechanisms, and the generation of high-frequency PWM signals. It was found that the designed mechanism could control the input and output voltages when the frequency changed according to the purpose. After testing the relationship between constant high voltage values and varied high frequency values, and the relationship between constant high frequency values and varied high voltage values, it was found that the optimal frequency was 10 kHz and the optimal voltage was 30 kV, which were sufficient to eliminate eukaryotic microorganisms in wastewater.
