Use of advanced oxidation processes for water treatment

Popis výsledku v původním jazyce

This paper investigates removal efficiencies of ozone and hydrogen peroxide based advanced oxidation processes (AOPs) on pharmaceuticals (antibiotics and non-steroidal anti-inflammatory drugs) in water solution, which are commonly presented in outflow of wastewater treatment plant. It is proved that AOPs are able to satisfactory remove these substances from water and interrupt its entrance to aquatic environment. Balance between removal efficiencies and costs is the main issue of current research into removing xenobiotics from wastewaters. To investigate justification of using costlier processes for reaching higher effectivity, sets of trials were performed. Artificially contaminated drinking water matrix was treated by various combinations of AOPs (O3, H2O2, UV, O3/UV, H2O2/UV, O3/H2O2) in flow through AOPs pilot unit. Evaluation of removal efficiencies for each AOPs combination was made. Study proves that AOPs are capable of pharmaceuticals removal, especially ozone-based processes which showed very high rate in removal of studied substances in comparison to hydrogen peroxide-based processes. However, coupling ozone with UV or hydrogen peroxide did not result in significant increase of pollutant removal and justification of higher costs is debatable.
