Success in Stably Storing Ozone by Hydration in a World First －Improved Usability of Ozone Gas, which is also Effective against COVID-19－
October 19, 2020
Professor Ryo Ohmura of the Keio University Faculty of Science and Technology, Department of Mechanical Engineering collaborated with researchers at IHI Corporation and the University of Ottawa, and succeeded in stably storing ozone for the first time in the world as well as developing a technology to continuously produce ozone hydrate. Ozone gas, which is the subject of this study and for which the technique was developed, is also said to be effective in inactivating COVID-19.
Traditional disinfectants use halides or strong acids and bases; however, because of their negative impact on the environment, the use of ozone has been considered, which has powerful disinfectant properties and high environmental affinity. Nevertheless, its use has been limited because it is difficult to preserve, and a technique to stably store it was therefore required.
In this study, a technology to manufacture ozone hydrate, the world's first technique to store high concentrations of ozone for long periods of time, was developed, and the researchers were successful in rapidly producing large quantities of ozone hydrate. In addition to inactivating COVID-19, ozone gas is effective in sterilizing and disinfecting food and tap water, and this technology is expected to have various industrial applications.
