Abstract

Persistent organic pollutants (POPs) are recalcitrant contaminants that are hardly removed by conventional water treatments. Incorrect disposal and incomplete treatment of POPs present serious risks to environmental and human health. Most of these compounds are toxic, have been identified as carcinogenic species, and/or endocrine disruptors. The need to search for new wastewater technologies has become a priority. Within this context, electrochemical advanced oxidation process (EAOP) emerged as viable alternatives to efficiently remove many POPs. However, most of studies on EAOPs capabilities reported in literature have been carried out in synthetic solutions in ultrapure water and using POPs concentrations orders of magnitude higher than the values generally found in the environment. A new path must be followed in order to face challenges on EAOPs implementation and technology translation to treat real effluents. This project aims to understand these challenges by studying (i) the effect of the real concentration of pollutants, (ii) the effect of water matrices components on the performance of electrochemical systems. In addition, it will be studied the stability of the different electrodes in the real/complex mediums. The performance of the EAOPs will be evaluated in terms of pollutants removal and engineering figures of merit such as Faradaic efficiency and energy consumption. (AU)
