“…On the other hand, synergistic effects can also be achieved by combing the O 3 with TiO 2 photocatalysis because an addition of O 3 increases the concentration of highly reactive species (OH • ) hydroxyl radicals in the medium, which further accelerates the process of organic matter degradation [14,64,65]. It is clearly evident from the results (Fig.…”

“…Hence, synergistic effects between ozone and photocatalysis can be achieved by using an optimal ozone concentration. An increase in ozone dose increased the decomposition of pollutants, but beyond optimal concentration, ozone starts to decrease the degradation process rather than increase it [71]. Therefore, in order to find out the optimal ozone dose for maximum SHWW degradation, ozone dose was varied between 2g/h-8g/h at pH 3 and reaction time of 40 min.…”

“…The results were in agreement with findings reported in the literature [67]. A significant increase in degradation of SHWW in terms of BOD, COD, and nitrogen was observed by Ag-TiO 2 -O 3 and resulted in 94%, 83%, and 71% removal, respectively, because doping of silver and the addition of ozone expedited the overall reaction rate due to the fact that silver enhances the electron-hole separation and act as electron reservoirs on TiO 2 surface and ozone initiates the radical chain reactions by producing the OH radicals in the presence of UV light, hence accelerating organic matter degradation [71,72].…”

The slaughterhouse industry generates massive amounts of highly polluted wastewater of environmental concern. The discharge of untreated slaughterhouse wastewater (SHWW) into water bodies may cause eutrophication, dissolved oxygen depletion, and change in water temperature, which may pose a threat to aquatic life [1-3]. The leaching/ percolation of SHWW may also lead to the contamination of groundwater resources [4]. Resultantly, people may suffer from diarrhea, typhoid fever, wool sorter diseases, pneumonia, asthma, and chest and respiratory diseases [5]. Therefore, it is highly desirable to treat SHWW before its discharge into water bodies in order to save the environment and human health [6]. The treatment of SHWW with physio-chemical (filtration, coagulation, chlorination, adsorption, sedimentation) and biological (up-flow anaerobic sludge blanket reactors, waste stabilization pond system, and sequencing batch reactors) processes, though, significantly removes its pollution load but cannot remove the recalcitrant contaminants [7]. Another disadvantage associated with physio-chemical

“…The highest humic acids removal efficiency, 79.4%, was achieved in the presence of 1.0% co-doped TiO 2 nanotubes with an Al:Fe ratio of 0.25:075. Shin et al (Shin, Jang et al, 2013) studied the removal of dichloroacetonitrile from drinking water by combined solar-photocatalysis and ozonation treatment. The dichloroacetonitrile removal rate by the solar/TiO 2 /O 3 process was two times faster than that of solar/TiO 2 .…”
