- 01GJ4SGFZ9F1AMZ0HAP89BMQMG abstract "Secondary effluent from wastewater treatment plants contains (bio)recalcitrant trace organic contaminants (TrOCs) that are discharged into the environment. Ozonation can offer a solution for TrOCs removal from effluent and has been extensively investigated with respect to reaction mechanisms, performance and control strategies in view of full-scale application. The ozone-activated peroxymonosulfate process (O3/PMS) is a relatively new and promising upgrade of ozonation for which research under real conditions is, however, still lacking. Therefore, this work focuses on the removal of 11 TrOCs with different ozone reactivity at environmentally relevant concentrations in effluent by using O3/PMS. At short reaction times, the hydroxyl radical exposure is approximately 2 times higher in O3/PMS than during ozonation at O3 concentrations exceeding the instantaneous ozone demand (IOD). The radical production during O3/PMS is even noticeable at ozone concentrations lower than the IOD, which indicates that radical reaction pathways are more important during the IOD phase in O3/PMS than during ozonation. At longer reaction times, also direct PMS oxidation enhances the removal of some TrOCs at low ozone concentrations (< IOD). However, the extra TrOCs removal during O3/PMS is overall limited compared to ozonation, i.e. up to 24 % extra removal at 0.5 min reaction time and the highest ozone concentration (12.3 mg/L). In a second part of this research, spectral surrogate models based on UV absorbance at 254 nm (UVA254) and fluorescence were developed for the prediction of TrOCs removal. The intensity of both surrogates decreased in a similar way as a function of the applied ozone concentration in both the ozonation and O3/PMS process. However, the regression parameters of the surrogate models and particularly the location of the inflection point show differences between both advanced oxidation processes.".
