Collection description
Wastewater is the main source of micropollutants and although treated in WWTPs, it can continue to contain recalcitrant substances, potentially dangerous for the health of living organisms and for the environment. These substances, known as emerging contaminants (ECs), represent a growing concern worldwide today. The reuse of treated wastewater in agriculture can represent a sustainable solution to address the growing demand for water and improve the management of water resources, however the problems related to the presence of these dangerous substances in them must be carefully examined and resolved. In this thesis, particular attention was paid to the transformation by-products of pharmaceuticals and personal care products (PPCPs) obtained through simulated chlorination processes that imitate the same ones normally present in WWTPs. A first part was dedicated to the chromatographic detection of degradation by-products and the evaluation of their toxicity. A further phase of the work involved the application of new strategies effective in removing a wide range of ECs. In this scenario, advanced oxidation processes (AOPs) offer a real opportunity for the removal of these pollutants from wastewater. In particular, the main objective was to apply REE-based heterogeneous liquid phase photocatalysis systems for the degradation of chemical and biological contaminants. The experimental activities have made it possible to develop and compare kinetic models of the AOPs and to evaluate the best combination and performance of the process in terms of degradation capacity of the chosen target contaminant. The potential of the experimental results obtained represents an interesting new perspective in eco-compatible treatments for the removal of emerging contaminants from wastewater effluents.
