Abstract The presence of emerging contaminants, such as antibiotics, in the environment has caused growing worldwide concern. Once in surface waters and other environmental matrices, such compounds can drive the spread of bacterial resistance, particularly in situations of large increase in drug consumption, such as pandemic health emergencies. The appearance of emerging contaminants in the environment has shown that conventional wastewater treatment methods are ineffective in removing these compounds, so new and more effective treatment processes need to be investigated and improved. The adsorption process and electrochemical oxidation are promising technologies that have been successfully applied to the removal/degradation of different organic pollutants. However, despite the electrochemical process being an attractive process for wastewater treatment, the low current efficiency is still a critical problem due to the mass transfer limitations in the case of dilute solution treatment, and the adsorption process requires a final stage of disposal and/or reuse of the saturated adsorbent. To address these questions, this research project aims to investigate a reaction system that allows the continuous treatment of effluents by adsorption and in situ electrochemical regeneration of low-cost unconventional adsorbent (clay). It is noteworthy that the electrochemical regeneration of adsorbents has not been widely investigated and studies that explore alternative adsorbents are rare. Furthermore, the electrochemical regeneration of clays has not yet been explored in the literature. Thus, this project intends to bring original scientific and technological contributions in a context in which the concern with treatment systems capable of removing contaminants of emerging interest has been gaining importance. | |
