El disseny actual de reactors per al\u00a0tractament biol\u00f2gic d\u2019aig\u00fces residuals\u00a0<\/strong>est\u00e0 enfocat a desenvolupar nous processos amb una \u00f2ptima capacitat d\u2019eliminaci\u00f3, un baix cost econ\u00f2mic en consum de mat\u00e8ries primes i energia, i un m\u00ednim impacte ambiental. Els models matem\u00e0tics i la simulaci\u00f3 poden ajudar a determinar i validar els par\u00e0metres claus de disseny, escur\u00e7ant d\u2019aquesta manera la durada dels treballs experimentals de R+D+I. Tot i aix\u00ed, encara cal incrementar la capacitat computacional d\u2019aquestes eines i superar les limitacions d\u2019alguns models actuals, com ara l\u2019assumpci\u00f3 d\u2019una \u201cmescla perfecta\u201d.<\/p>\n

 <\/p>\n

La tesi\u00a0“Integrating computational fluid dynamics and biological models to assess wastewater reactor design”<\/strong>d\u2019Albert Vil\u00e0 Rovira<\/a><\/strong>\u00a0ha integrat\u00a0models biol\u00f2gics\u00a0<\/strong>– en concret, models de fangs activats \u201cASM\u201d (en angl\u00e8s,\u00a0Activated Sludge Models<\/em>) – amb eines de simulaci\u00f3 de\u00a0din\u00e0mica de fluids computacional\u00a0<\/strong>\u201cCFD\u201d (en angl\u00e8s,\u00a0Computational Fluid Dynamics<\/em>), i les ha aplicat al disseny de dues tecnologies avan\u00e7ades per al tractament de les aig\u00fces residuals: les \u201cMicrobial Fuel Cells\u201d o piles bioelectroqu\u00edmiques i el proc\u00e9s \u201cAnammox\u201d. El sistemes de tractament d\u2019aig\u00fces residuals basats en\u00a0Microbial Fuel Cells\u00a0<\/strong>aprofiten l\u2019activitat catal\u00edtica bioelectroqu\u00edmica de determinats microorganismes per oxidar compostos org\u00e0nics i produir electricitat sense necessitat d\u2019addicionar compostos qu\u00edmics. Tamb\u00e9 en el\u00a0proc\u00e9s\u00a0Anammox<\/em><\/strong>\u00a0(Anaerobic Ammonium Oxidation<\/em>) els protagonistes s\u00f3n els microorganismes, en aquest cas per eliminar de manera autotr\u00f2fica compostos de nitrogen, i reduir aix\u00ed la quantitat de fangs generats i les necessitats d\u2019aeraci\u00f3. L\u2019investigador ha realitzat la tesi doctoral al grup\u00a0LEQUIA<\/a>\u00a0de la Universitat de Girona, amb un gran bagatge en projectes de recerca experimental i contractes de transfer\u00e8ncia per optimitzar aquestes dues tecnologies. Aix\u00f2 li ha perm\u00e8s interaccionar amb investigadors experts i con\u00e8ixer de prop la seva implementaci\u00f3 a escala industrial.<\/p>\n

 <\/p>\n

Els\u00a0resultats\u00a0<\/strong>obtinguts demostren que el potencial d\u2019integrar la din\u00e0mica de fluids computacional i els models biol\u00f2gics per dissenyar reactors biol\u00f2gics de tractament d\u2019aig\u00fces residuals, \u00e9s molt alt. Entre els par\u00e0metres que s\u2019han estudiat destaca la influ\u00e8ncia de la configuraci\u00f3 del reactor en la distribuci\u00f3 del substrat i en les velocitats d\u2019eliminaci\u00f3 de nutrients. En el cas de les\u00a0Microbial Fuel Cells,<\/em>\u00a0s\u2019han avaluat diferents materials per a l\u2019el\u00e8ctrode i s\u2019ha considerat la geometria, composici\u00f3 i propietat el\u00e8ctriques. L\u2019\u00fas de grafit granular i malla d\u2019acer inoxidable ha resultat afavorir la distribuci\u00f3 del flux a trav\u00e9s de l\u2019\u00e0node, essent l\u2019\u00faltima opci\u00f3 la m\u00e9s v\u00e0lida per les seves propietats el\u00e8ctriques i baix cost. Pel que fa al proc\u00e9s\u00a0Anammox<\/em>, s\u2019ha demostrat que l\u2019\u00fas de plats interns afavoreix la distribuci\u00f3 del flux i que la introducci\u00f3 de corrents d\u2019alimentaci\u00f3 laterals al llarg de la columna del reactor augmentaria la velocitat d\u2019eliminaci\u00f3 de compostos de nitrogen. Per obtenir resultats de simulaci\u00f3 m\u00e9s fiables, es podria incloure una fase s\u00f2lida que represent\u00e9s el fang involucrat en el proc\u00e9s biol\u00f2gic.<\/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
