20.500.12556/RUL-126481 The removal of bisphenols and other contaminants of emerging concern by hydrodynamic cavitation from lab-scale to pilot-scale The rapid growth in the variety and quantity of contaminants of emerging concern (CEC) in wastewater indicates the necessity for developing efficient and environmentally friendly methods for their removal. This study investigates the removal efficiency of 46 CEC, including 12 bisphenols, from wastewater using a lab and pilot-scale hydrodynamic cavitation generator alone and in combination with UV illumination (pilot-scale). During lab-scale cavitation, the highest removal efficiencies of bisphenols (15-63%) for this specific design of cavitator were obtained at a rotational frequency (vcav)=9500 rpm and time (tcav)=10-min. Temperature and the physicochemical properties (e.g. Kow) of the studied compounds also had a significant effect on removal efficiency. At the pilot-scale, 11 CECs were quantifiable in the wastewater influent, and the generator operated at cav=2290 and 2700rpm. The highest removal efficiencies (15-90%) were obtained at a lower cav=2290 rpm while neither an increase in cav, tcav or the presence of UV-C light increased the removal efficiency. A lower cav also reduced the hydrodynamic power of the cavitator from 477W to 377W, resulting in reduced energy consumption. Overall, the results show the potential of hydrodynamic cavitation for a large-scale application as a pre-treatment technology and pave the way for future improvements in the design of cavitation reactors. contaminants of emerging concern bisphenol hydrodynamic cavitation UV Lab-scale pilot-scale kontaminanti bisfenol hidrodinamična kavitacija UV laboratorijska lestvica pilotna lestvica true false true Angleški jezik Slovenski jezik Članek v reviji 2021-04-23 10:30:47 2021-04-23 10:30:51 2025-03-14 13:26:23 0000-00-00 00:00:00 2020 0 0 Str. 1-7 Vol. 743 2020 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 2020-11-15 2022-11-15 547:615 0048-9697 10.1016/j.scitotenv.2020.140724 21591299 RAZ_Kovacic_Ana_2020.pdf RAZ_Kovacic_Ana_2020.pdf 1 88E2A41433D8A37EDE696166C27F46B2 de51781223a8f6414ab1dd5ac84cfea3d736a3a94ba60297dee74d6b487e39b6 f77c4fb1-ac04-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142728 https://www.sciencedirect.com/science/article/pii/S0048969720342467?via%3Dihub 1 34b1b780-a40e-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142461 Fakulteta za strojništvo 0 0 0
