Abstract

This study has been carried out to achieve high energy efficiency for a water purification method using a plasma generation with cavitation bubbles. In the method proposed herein, the pressure loss in the water flow path of the treatment reactor is reduced by removing the nozzle for the generation of cavitation. Cavitation bubbles can be generated between the electrodes installed in the flow path by adjusting the water flow rate. With and without nozzle, a similar degree of Escherichia coli sterilization was achieved. In the proposed system, the power consumption of the pump was reduced by removing the nozzle, and as a result, the total power consumption of the apparatus could be reduced.
