Ozonisation is a chemical water treatment technique based on the infusion of ozone into the water, which can be a powerful oxidant, destroying a wide range of organic compounds and microorganisms (Environmental Protection Agency, 1999; Meijers, 1977; Tzortzakis, 2016). In 2014, one of the most modern wastewater treatment plants in the world was brought online established in Dübendorf, Switzerland, which was the first facility in the country to treat micro-pollutants by ozonation followed by a proprietary sand filtration process (McArdell, 2015). This plant was designed to protect Lake Zurich in accordance with new Swiss legislation. Limiting the micro pollutants discharge in the environment has also become a new issue in connection with organic pollution (Abdel-Raouf, Al-Homaidan, & Ibraheemet al., 2012), with organizations needing to recover and preserve their surface and groundwater environments. Conventional municipal wastewater treatment plants (WWTP) have also become important targets for the upgrading and the implementation of advanced ozone water treatment technologies as tertiary treatment appears essential to protect receiving water bodies (Eggen, Hollender, Joss, Schärer, & Stammet al., 2014; Rice, 2002).
