| Research Abstract |
We developed a water disinfection treatment approach using ozone microbubbles generated by a hollow ultrasonic horn, and investigated the effect of inactivation for Escherichia coli with this treatment. Experimental results reveal that this treatment involves efficient disinfection of Escherichia coli. This treatment using ozone microbubbles generated by a hollow ultrasonic horn led to efficient disinfection, owing to the high solubility of the microbubbles and the synergism of the ozone and ultrasonic irradiation, i.e. the enhancement of ozone self-decomposition and radicals generation.
