“…Among all compounds detected, only six of them were suitable for inclusion in the index calculation as most of the compounds were detected at very low concentrations and did not meet the above-described criteria. The selected compounds for index calculation were propranolol ( k O3 ≈ 1.7 × 10 5 M –1 s –1 ; k OH ≈ 7.5 × 10 9 M –1 s –1 ), losartan ( k O3 ≈ 1.2 × 10 5 M –1 s –1 ; k OH not available), prednisone ( k O3 not available; k OH not available), diclofenac ( k O3 ≈ 1 × 10 6 M –1 s –1 ; k OH ≈ 7.5 × 10 9 M –1 s –1 ), ibuprofen ( k O3 ≈ 9.6 M –1 s –1 ; k OH ≈ 7.4 × 10 9 M –1 s –1 ), and venlafaxine ( k O3 ≥ 1 × 10 3 M –1 s –1 ; k OH ≈ 8.8 × 10 9 M –1 s –1 ). − …”

Despite the well-known efficiency of ozonation in treating secondary effluents and its increasing global application, the removal of micropollutants is still a matter of concern. Ozone installations for tertiary treatment are typically installed with specific objectives such as disinfection, color and odor removal, and micropollutant removal, among others. However, due to factors such as the absence of legislation in many countries, complexity, and cost of analysis, for example, the accurate assessment of micropollutant removal during ozonation is limited to a few legislated compounds. This study aimed to contribute to the evaluation of pharmaceutical removal by introducing an index that correlates the inactivation of common bacteria widely used as disinfection indicators (total coliforms and Escherichia coli) with the removal of micropollutants during ozonation of secondary effluents. The developed index, named Microlog, was tested in three different wastewater treatment plants and compared with existing literature data. Strong correlations were observed between the log 10 reduction of bacteria and the percentage of specific micropollutant removal, regardless of the effluent quality. The Microlog concept can serve as an additional tool for assessing the final removal of micropollutants when the ozone disinfection of the wastewater treatment plant effluent is measured.

Technology advancement improves the quality of life, however, it might also introduce new pollutants to the ecosystem, which needs to deal with for the goal of a sustainable ecosystem. Municipal and industrial wastewater has always been important in improving the quality of life while maintaining the sustainability of our planet simultaneously. The diversity of pollutants in wastewater requires more advanced and demanding treatment processes. The ozonation, as a crucial part of the advanced oxidation processes, is a superior oxidation method compared to traditional oxidation methods. After the recognition of ozone as GRAS (generally recognized as safe), its applications have diversified and is used currently for microbial inactivation, degradation of recalcitrant organic compounds, removal of a diverse range of micropollutants, solubilization and reduction of sludge, and removal of color and odor components in wastewaters treatment processes. However, some considerable challenges still exist towards its universal application, such as high ozone generation costs, diversity of pollutants, and formation of ozonation by-products, which still require further studies. The main theme of this review paper is the transformation of traditional oxidation methods into advanced oxidation processes and the role of ozonation in this regard, including its applications, by-products, and its comparison with the traditional oxidation methods and advanced oxidation processes.

Simultaneous ozonation of 90 organic micropollutants including illicit drugs and their metabolites in different water matrices

Abstract: The ozonation of 90 chemically diverse organic micropollutants (OMPs) including four classes of illicit drugs and their metabolites was studied in pure buffered water, tap water and wastewater effluent at three specific ozone doses and three pH levels.
