Abstract
Ozone is superior to conventional disinfectants such as alcohol and chlorine as it is highly effective, environmentally friendly, and non-carcinogenic. However, ozone is not commonly used because of its short concentration lifespan. In this research, ozone ultrafine bubbles (UFB) were created, and experiments were conducted with the aim of obtaining ozone water with a long lifespan. The effect of the particle size distribution of ozone UFB on the concentration and the lifespan was measured. The ozone concentration increased by up to 75% with an increase in the number of bubbles. The lifespan of ozone concentration was partially increased, while the lifespan of ozone concentration decreased as the circulation time increased. The ozone UFB water was effective in killing Escherichia coli bacteria, and the effect lasted for one day. This may be due to the increase in the concentration of ozone in UFB water.
