Comparison of the advanced oxidation processes in the degradation of pharmaceuticals and pesticides in simulated urban wastewater: Principal component analysis and energy requirements

Pollutants such as pharmaceutical products and pesticides are still present in treated water. Several of these compounds photoactive. The photodegradation eight organic pollutants was studied using listed advanced oxidation processes: UV/H2O2, UV/persulfate, Fenton, photo-Fenton UV/TiO2. results show that is most effective the first 10 min treatments simulated urban wastewater collected from local Nišava River. To identify correlation between applied degradation processes well relationship among structure investigated efficiency degradation, Pearson’s coefficient analysis principal component (PCA) were performed. established correlations processes, determination influence on enable a more efficient choice procedure, especially case interference. Additionally, process electrical energy consumption treatment costs for with different pharmaceuticals determined.
