Ozonation By-Products

Persistent contaminants of emerging concern in ozone‐biofiltration systems: Analysis from multiple studies

“…Organic macromolecules with highly susceptible sites for ozone oxidation, such as aromatic and amino acids functional groups, can react to form oxidation byproducts such as aldehydes, ketones, and carboxylic acids (Legube, 2003), as well as nitrosamines such as NDMA and NMOR (Bacaro et al, 2019;Bourgin et al, 2018;D. Li et al, 2017).…”

Catalytic ozonation of fenofibric acid over alumina-supported manganese oxide

“…Among them, heterogeneous catalytic ozonation has received attention due to the simplicity of catalyst recovery. It is also a choice to limit the formation of oxidation intermediates [9,10]. Alumina and aluminasupported metal oxides exhibit a high activity for the gas phase ozone-assisted oxidation of volatile pollutants [11].…”

Qualitative and Quantitative Analysis of the Inorganic Materials Changes with Time in the Stages of the Wastewater Treatment Plant

“…Furthermore, the phosphate compounds, and particularly the polyphosphates, were proposed as good removals to the inorganic wastes [7]. Chemical oxidants such as ozone, chlorine, chlorine dioxide, and chloramines, besides their disinfection role, were also used since a number of organic and inorganic compounds can go reactions with these oxidants [8][9][10][11][12][13][14][15][16]. One case of oxidants is chlorine, which was reported capable to undergo reactions with numerous inorganic and organic micro pollutants [17].…”

“…In water treatment using chemical oxidants, the ozone, chlorine, chlorine dioxide, and chloramines are reported used for various purposes: disinfection of microorganisms, oxidation in taste and odor control, and elimination of the micro pollutants [8][9][10][11][12][13][14][15][16]. Under certain circumstances, these oxidants could induce the formation of the harmful by-products due to their highly reactivity with water matrix components and micro pollutants [18][19][20][21][22][23][24].…”
