| Outline of Final Research Achievements |
An energy-saving type of nonthermal plasma sterilization system is proposed and established. The system utilizes electrolysis of water to produce oxygen and hydrogen. The oxygen is a source of ozone for sterilizations, and the hydrogen is used for electric power generation in fuel cells. The system can supply the oxygen into a plasma ozonizer with an energy efficiency of 0.10 L/Wh at a high concentration of 99.9%, and the harmful nitrogen oxide is not generated as a byproduct. An environmental-friendly sterilization system is achieved. As for sterilization effect, bubbling of the produced ozone for only 5 min achieves a complete sterilization against 500 mL of used bathtub water.
