Outline of Final Research Achievements

A nobel reactive plasma device for water purification was developed successfully by utilizing a single or two capillary discharges with sudden expansion diameter. It aims at the establishment of decomposition of persistand organic pollutants with high energy efficiency and control of water purification process. The correlation between discharge characteristics and generated bubble hehavior in the cappillaries, flow pattern, pump performance, and decolorization characteristics of methylene blue were experimentally clarified each other.
The time dependent 2D diffusion model for oxidized radicals in the nano pulsed discharged bubble and treated solution outside bubble was successfully established. The optimum operating condition for high OH radical concentration in the solution was clarified by comparing with experimental data to obtain the high energy efficiency.
