L\u2019alt contingut de nitrats (NO3-) en aig\u00fces subterr\u00e0nies \u00e9s un tema de preocupaci\u00f3 global. A algunes zones geogr\u00e0fiques com Catalunya, les concentracions de nitrat excedeixen els l\u00edmits marcats per a la Organitzaci\u00f3 Mundial de la Salut (OMS) per al consum hum\u00e0 (50 mgNO3-\u00b7L-1\u00a0 o 11.29 mgN\u00b7L-1). Les tecnologies disponibles\u00a0 a l\u2019actualitat (osmosi inversa, electrodi\u00e0lisi inversa i intercanvi i\u00f2nic) poden reduir el contingut de nitrats per sota de l\u00edmit legal per aigua potable. Tanmateix, el seu alt cost energ\u00e8tic i ambiental – concentren els nitrats en salmorra de dif\u00edcil tractament – en limiten la utilitzaci\u00f3. Per tot aix\u00f2, cal cercar noves tecnologies que permetin el tractament de nitrats a un cost econ\u00f2mic i ambiental assequible.<\/p>\n

 <\/p>\n

La tesi \u201cBioremediation of nitrate-polluted groundwater using bioelectrochemical systems<\/strong>\u201d de l\u2019investigador del LEQUIA\u00a0Narc\u00eds Pous i Rodr\u00edguez<\/a>\u00a0s\u2019ha centrat en investigar la utilitzaci\u00f3 de sistemes bioelectroqu\u00edmics (BES) per al tractament d\u2019aig\u00fces subterr\u00e0nies contaminades amb nitrats. Els sistemes bioelectroqu\u00edmics aprofiten la capacitat de determinats microorganismes per a realitzar processos d\u2019oxidaci\u00f3\/reducci\u00f3 a base d\u2019alliberar\/captar electrons d\u2019un el\u00e8ctrode. Narc\u00eds Pous ha investigat l\u2019\u00fas de bact\u00e8ries per a utilitzar l\u2019el\u00e8ctrode com a donador d\u2019electrons (bioc\u00e0tode) i reduir aix\u00ed el nitrat a dinitrogen gas, que \u00e9s un compost inert. Com a resultat, s\u2019ha desenvolupat un proc\u00e9s patentat pel grup LEQUIA\u00a0(WO\/2014\/082989) que tracta els nitrats a altes velocitats de desnitrificaci\u00f3 (fins a 700 gN\u00b7m-3NCC\u00b7d-1) i a un cost energ\u00e8tic competitiu (0.68\u00b710-2\u00a0\u2013 1.27\u00b710-2\u00a0kWh\u00b7gN-1tractat). Tot aix\u00f2, sense generar fangs ni addicionar subst\u00e0ncies qu\u00edmiques. D\u2019altra banda, tamb\u00e9 s\u2019han determinat les caracter\u00edstiques electroqu\u00edmiques dels microorganismes i s\u2019han elucidat les subcomunitats microbianes responsables de la desnitrificaci\u00f3.<\/p>\n

 <\/p>\n

En definitiva, la tesi \u2013 que ha estat dirigida pels doctors Sebasti\u00e0 Puig Broch, Maria Dolors Balaguer Condom i Jes\u00fas Colprim Galceran del LEQUIA de la Universitat de Girona \u2013 ha demostrat que\u00a0els sistemes bioelectroqu\u00edmics, operats de forma adient, tenen el potencial de convertir-se en una alternativa competitiva pel tractament d\u2019aig\u00fces subterr\u00e0nies contaminades per nitrats.<\/strong><\/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
