The efficiency of ozone in groundwater remediation is limited by its relatively low solubility and rapid decomposition in the aqueous phase. In this study, the characteristics of ozone micro-nano-bubbles (MNBs) were examined, including their size distribution, bubble quantity, and zeta potential. The mass transfer rate of ozone MNBs was experimentally investigated, and column tests were also conducted to study the efficiency of ozone MNBs for organics-contaminated groundwater remediation. Based on the lab tests, field monitoring was conducted on a TCE-contaminated site, where results indicated that ozone MNBs improved remediation efficiency. Additional information on this technology is available in a U.S. patent application at https://patents.google.com/patent/US20150041392.
