| Research Abstract |
Water disinfection treatment using ozone microbubbles generated by a hollow ultrasonic horn was developed, and its ability to inactive Escherichia coli in water was evaluated. The times required for complete sterilization by the disinfection treatment with ozone microbubbles generated by the hollow ultrasonic horn, ozone bubbles generated by a disperser with ultrasonic irradiation, and ozone bubbles generated by a disperser under the same ozone gas supply conditions were 15, 27, and 30 min respectively, which indicates that ozone bubbling with ultrasonic irradiation enhances disinfection.
