“…Ozone, on the other hand, has been described as an efficient disinfection agent, able not only to control bacteria, but also to oxidize organic matter in municipal effluents [7]. However, despite its high potential for application in municipal effluent, relatively few papers dealing with this approach have been reported [8,9].…”

UV radiation and ozonation were investigated as disinfection alternatives for the wastewater treatment plant. The inactivation of total and fecal coliforms using ozone and ultraviolet radiation as separate treatments was evaluated. Different ozone concentrations (3 to 40 mg O 3 /L) were applied and UV fluencies ranging from 8.5 to 12 mJ/cm 2 at different pH values (from 5 to 9) were tested. Best results were obtained for ozone doses near 20 mg/min with removals of 72% and 78% of fecal and total coliforms, respectively. The ozone also was capable of oxidizing organic matter in the effluent measured as COD (the highest removal obtained was 36% for 20 mg O 3 /min). Maximum bacterial resistance was observed at pH 7 in both cases. The UV light offered a high bacterial inactivation (over 80%) and the lowest bacterial inactivation was observed at pH 7. Finally, we obtained the electric energy per order (E EO , kWh/m 3 /order), defined as the electric energy (kW-h) required to degrade a contaminant by one order of magnitude in a unit volume of contaminated water, being noteworthy that E EO values for the UV process resulted were lower than those determined for the process with ozone in all the water flow tested.

“…Ozonation. Salveson et al (2008) assessed the potential benefits of the HiPOx TM system, an ozone-based pressurized in-vessel system, which could be utilized as an UV Disinfection. Beltran and Jimenez (2008) evaluated the efficiency of UV to inactivate microbial indicators in three secondary effluents.…”
