Résumé
This doctoral thesis aims to contribute to the advancement in knowledge and technological development of the recovery of materials contained in waste streams by integrating renewable energy sources with electro-membrane technologies, making an impact on both technical and environmental feasibility aspects. It has been considered the obtaintion of HCl and NaOH from desalination brines using the integrated process of photovoltaic solar-electrodialysis with bipolar membranes (EDBM-PV) as a case study. The production of acids and bases would potentially allow, depending on the concentration and purity achieved, to meet the on-site demand derived from the operations of conditioning currents within a desalination plant, or the possibility of marketing both products. The improvement in the environmental sustainability of the desalination plant would come mainly from the integration of PV solar energy (reduction of indirect environmental burdens) and the reduction of external consumption of chemical products.
