DQO, al finalizar el periodo de operación,
fueron de 67,3%, para CCM3 y 69,8%,
para CCM6. Con relación a la remoción
de DBO, los resultados obtenidos fueron
de 55,9 y 60,6%, para CCM3 y CCM6,
respectivamente. Considerando los
resultados obtenidos, se concluye que
es posible generar valores significativos
de energía eléctrica, con simultánea
remoción de materia orgánica, usando,
como sustrato, agua residual de
curtiembre, en una celda de combustible
microbiano. En consecuencia, el presente
trabajo constituye un aporte para la
optimización de sistemas de tratamiento
de aguas residuales de curtiembres y su
potencial aprovechamiento como fuente
de energía renovable.
