Ozonation: effective way for removal of pharmaceuticals from wastewater
Original language description
The objective of the presented paper is to characterize the effectiveness of the removal of pharmaceuticals from wastewater during ozonation in laboratory-scale conditions. Almost 100 pharmaceuticals and their metabolites from different therapeutic classes were studied in effluent from the wastewater treatment plant, Devinska Nova Ves, used for ozonation. Telmisartan, diclofenac, and fexofenadine were found at the highest concentrations (1800 ng/dm(3), 680 ng/dm(3), and 620 ng/dm(3), respectively). The concentrations of another 13 pharmaceuticals and metabolites exceeded 100 ng/dm(3), and the rest of the compounds were below 100 ng/dm(3). These water samples underwent ozonation in intervals of 0-10 min. The flow of ozone during the test was 50 mg O-3/min. The results show that the removal of pharmaceuticals is significant after the first minute of ozonation, when most of the studied compounds were below the limit of quantification. The total concentration of the studied compounds after the first minute decreased to 190 ng/dm(3) (97.2% removal efficiency). More than 99% removal efficiency was achieved after 10 min of ozonation.
