L’aigua destaca com el recurs m\u00e9s essencial, tot i que actualment es troba sota una amena\u00e7a seriosa. La combinaci\u00f3 de l’escassetat d’aigua i l’increment de la contaminaci\u00f3 de l’aigua disponible planteja reptes significatius per a l\u2019administraci\u00f3 i la societat. Normalment, aquest problema s’agreuja a les \u00e0rees rurals a causa de l’acc\u00e9s limitat als serveis de gesti\u00f3 de l’aigua. En aquestes regions, les pr\u00e0ctiques agr\u00edcoles modernes i la ramaderia intensiva contribueixen de manera significativa a la contaminaci\u00f3 de l\u2019aigua per nitrats. En aquests escenaris, hi ha una necessitat urgent de desenvolupar solucions sostenibles de tractament descentralitzat. Aquesta tesi de doctorat se centra en l’electro-biorremediaci\u00f3, que aprofita la capacitat de certs microorganismes per intercanviar electrons amb un material s\u00f2lid. Espec\u00edficament, l’eliminaci\u00f3 de nitrats es basa en la seva reducci\u00f3 a gas dinitrogen utilitzant un c\u00e0tode com a donador d’electrons. Aquest proc\u00e9s innovador elimina la necessitat d’introduir productes qu\u00edmics com a agents reductors a l’aigua, una pr\u00e0ctica comuna en els tractaments convencionals, i al mateix temps evita la generaci\u00f3 de qualsevol residu. Aquest \u00e9s el principal avantatge del tractament, que requereix una quantitat m\u00ednima d’energia per aconseguir l\u2019eliminaci\u00f3 de nitrats. Aquesta tesi descriu el desenvolupament de l’electro-biorremediaci\u00f3 des d’experiments al laboratori fins a la construcci\u00f3 d’una planta pilot on-site. Es va comen\u00e7ar amb experiments de laboratori per entendre la reducci\u00f3 de nitrats en aquests sistemes per tal d’optimitzar el proc\u00e9s. A m\u00e9s, l’estudi explora la plena explotaci\u00f3 d’aquesta tecnologia per abordar altres contaminants, com ara l\u2019ars\u00e8nic i els pat\u00f2gens. Finalment, la tecnologia es va validar mitjan\u00e7ant un tractament real en una planta pilot on-site. Els resultats globals demostren la competitivitat econ\u00f2mica d’aquest tractament i encoratgen per continuar la recerca en aquesta \u00e0rea<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
