“…It is mostly excreted unchanged to the environment 7 and it was detected more than the reference threshold of 100 ng/L both in in ow and e uents of WWTPs, rivers, sewage hospital 8, 9 . In addition to FUR, related metabolites (saluamine and pyridinium of FUR) can be also found in raw wastewater but their removal in the WWTPs is generally very high (> 80%) 10 . However, the availability of literature data regarding the development of processes and technologies suitable for e cient drug removal from water is very limited.…”

The degradation in water of furosemide (FUR), a widely used diuretic drug, was herein reported. The method entails an integrated approach based on the hybridisation of hydrodynamic cavitation (HC) with electrical discharge (ED) plasma technology. This dynamic duo could increase the production of oxidising compounds in water, in particular hydroxyl radicals (OH radicals), by triggering the rapid homolytic decomposition of water molecules and avoiding the addition of external oxidants. This study clearly emphasises the effectiveness of an integrated approach to improve the degradation of pollutants in wastewater originating from active pharmaceutical ingredients (APIs). The results of HC/ED-assisted FUR degradation in the presence of radical scavengers highlight the predominant role of the radical oxidation mechanism at the gas-liquid interface of the cavitation bubble during HC/ED treatment. A comparative analysis of the three technologies — HC alone, HC/ED and UV alone — emphasised the promising potential of hybrid HC/ED as a scalable industrial technology. This is demonstrated by the higher degradation rates (100%, 10 min) when treating large volumes (5L) of wastewater contaminated with FUR (50mg/L), even in the presence of other APIs.
