Water purification by plasma microbubble generator in flowing water

Abstract

Plasma activated water (PAW) has been studied as the remarkable technique for sterilization process, water purification and agriculture. Effective method to generate high concentration PAW is required. In this study, we invent a novel technique to generate PAW by combining microbubbles and plasma technology in a water recirculation system. Venturi type setup is used to generate microbubbles. The motion of bubbles in the pipe is measured by optical flow technique.
