L’amoni (NH4+) \u00e9s un contaminant present a tot tipus d’aig\u00fces, fet que ocasiona m\u00faltiples problemes mediambientals i de salut. Actualment, hi ha diverses tecnologies disponibles al mercat per eliminar amoni, per\u00f2 totes consumeixen molta energia i, conseq\u00fcentment, s\u00f3n molt cares. Les tecnologies electromicrobianes (en angl\u00e8s, METs) utilitzen microorganismes electro-actius i s\u00f3n una alternativa biotecnol\u00f2gica de baix consum energ\u00e8tic per convertir l\u2019amoni en nitrogen gas (N2<\/sub>). Tot i aix\u00ed, encara fa falta realitzar recerca i desenvolupament industrial per assolir resultats competitius a escala real. La tesi doctoral\u00a0\u201cBioelectrochemical systems for ammonium removal in contaminated water\u201d de Miguel Osset \u00c1lvarez<\/strong>\u00a0t\u00e9 com a objectiu contribuir al desenvolupament de dues de les principals METs d’eliminaci\u00f3 d’amoni: la nitrificaci\u00f3 bioelectroqu\u00edmica i la combinaci\u00f3 de nitrificaci\u00f3 aer\u00f2bica amb desnitrificaci\u00f3 bioelectroqu\u00edmica.<\/p>\n

La\u00a0nitrificaci\u00f3 bioelectroqu\u00edmica<\/strong>\u00a0\u00e9s una tecnologia molt prometedora per eliminar NH4<\/sub>+<\/sup>. Tot i aix\u00f2, els mecanismes darrere d’aquest proc\u00e9s no han estat completament dilucidats. Miguel Osset va construir, operar i estudiar un sistema bioelectroqu\u00edmic nitrificant (niBES; sigles en angl\u00e8s) durant 550 dies. Es va descobrir que el microorganisme dominant al niBES era un nitrificant (Achromobacter sp.), i que la hidroxilamina (NH2OH) i el nitrit (NO2-), dos intermediaris de la nitrificaci\u00f3, s\u00f3n compostos electroactius. En general, aquests resultats suggereixen que l’amoni es va transformar en nitrogen gas (N2) mitjan\u00e7ant un proc\u00e9s que combina l’oxidaci\u00f3 bioelectroqu\u00edmica de NH4+, la desnitrificaci\u00f3 i, menys, l’anammox.<\/p>\n

D’altra banda, es va construir un nou\u00a0sistema bioelectroqu\u00edmic (BES; sigles en angl\u00e8s) d’eliminaci\u00f3 d’amoni, l’e-biofiltre,<\/strong>\u00a0integrant la desnitrificaci\u00f3 bioelectroqu\u00edmica en un biofiltre percolador. Es van utilitzar els e-biofiltres per transformar l’NH4+ present en aigua sint\u00e8tica d’aq\u00fcicultura en nitrat (NO3-) i N2, cosa que va permetre reutilitzar aquesta aigua per a cultiu hidrop\u00f2nic. A m\u00e9s, els e-biofiltres van ser capa\u00e7os d’eliminar la major part de l’amoni, la mat\u00e8ria org\u00e0nica i els s\u00f2lids en suspensi\u00f3 presents a l’efluent secundari d’una planta de tractament d’aig\u00fces residuals (EDAR) urbana, cosa que demostra que els e-biofiltres poden proporcionar un tractament hol\u00edstic de les aig\u00fces residuals.<\/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
