Professor Ryo Ohmura of the Department of Mechanical Engineering, Faculty of Science and Technology, Keio University, in collaboration with IHI Corporation and the University of Ottawa, has developed the world's first technology to stably store ozone and continuously produce ozone hydrate. The ozone gas, which is the subject of this research, is also reported to be effective in inactivating the novel coronavirus.
Traditionally, halogens and strong acids/bases have been used as disinfectants, but due to their negative environmental impact, the use of ozone, which has strong sterilizing properties and is environmentally friendly, has been considered. However, its use has been limited because it is difficult to store, and there has been a need for a technology to stably store ozone.
In this study, we have developed a manufacturing technology for ozone hydrate, the world's only technology capable of storing ozone at high concentrations for long periods, and have succeeded in the rapid and mass production of ozone hydrate. Ozone gas is effective not only for inactivating the novel coronavirus but also for disinfecting and sterilizing food and tap water, and this technology is expected to be applied in various industries.
