Pilot-scale evaluation of UV/O3 oxidation, UV irradiation, and GAC filtration for removal of gabapentin and ibuprofen and impacts on selected physicochemical properties of treated wastewater

Popis výsledku v původním jazyce

This study evaluates the pilot-scale performance of a combined tertiary wastewater treatment system integrating ozone-based UV oxidation (UV/O3), secondary UV irradiation, and granular activated carbon (GAC) filtration at the Moravský Beroun WWTP. The novelty lies in assessing the influence of high-rate (100 %) internal recirculation on pharmaceutical removal and evaluating treatment effects on wastewater ion composition and trace element speciation. The full treatment sequence (UV/O3 → UV → GAC) achieved >99 % removal of gabapentin (GAB) and ibuprofen (IBU). Standalone UV/O3 removed 69.7 % of GAB and 92.2 % of IBU at the highest ozone dose (16.7 g O3/m3), whereas high-rate recirculation reduced oxidative treatment efficiency (GAB 28.8–36.7 %, IBU 45.4–69.6 %) due to increased pharmaceutical mass flux and lower oxidant availability. Secondary UV irradiation provided an additional 11–40 % removal, and GAC consistently ensured >99 % total removal. Despite high bicarbonate concentrations acting as radical dotOH scavengers, the combined treatment effectively mitigated radical quenching. Residual chemical oxygen demand (CODCr) after GAC treatment was typically
