This study investigates the effectiveness of using ozone as a disinfectant for wastewater treatment and its ability to reduce the emerging generations of micro pollutants as well as reducing the global and chronic toxicity. The following pollutants were of interest: coliforms thermotolerant spores, enterococci, pharmaceutical residues, surface active agents and nonyphenols. Pilot scale tests were performed using a biological treated domestic type wastewater and a physical/chemical treated domestic-industrial type wastewater with a strong industrial fraction. Ozone proved to be a technology that could simultaneously reduced significantly the overall concentration of the different pollutants analyzed without producing any toxic byproducts.
