“…Este valor de densidad de potencia es similar a los valores reportados por otros investigadores en el tratamiento de aguas residuales domésticas (Cuadro V). La densidad de potencia alcanzada es mayor a la reportada por Rodrigo et al (2007) significativamente conforme a la arquitectura de la CMC (diferencias en las configuraciones), materiales, tipos de sustrato, TRH y tasa de carga (si se maneja con régimen continuo; Logan et al 2006, Wang et al 2011. Por otro lado, Rodrigo et al (2007) mencionan que la densidad de potencia máxima tiene una relación directa con la concentración de la DQO.…”

“…Esto concuerda con lo reportado por , quienes a pesar de obtener una potencia máxima de 26 mW/m 2 y remover el 80 % de la DQO inicial del agua residual, encontraron que la EC de la CMC fue inferior a 12 %, lo que indica que gran parte de la materia orgánica no contribuyó a la generación de electricidad. Por su parte, Rodrigo et al (2007) mencionan que un mínimo porcentaje de la DQO es eliminado por el proceso de generación de electricidad.…”

Palabras clave: digestión anaerobia, remoción de materia orgánica, sistema acoplado, densidad de potencia, eficiencia coulómbica RESUMENSe evaluó el desempeño de un sistema compuesto por un reactor anaerobio de flujo ascendente (RAFA) y una celda microbiana de combustible (CMC) en el tratamiento de agua residual de baja carga, así como la recuperación de energía de este sistema. El reactor RAFA (1 L) se alimentó de manera continua con agua residual domés-tica bajo tiempos de retención hidráulica (TRH) de 12 y 6 h. La CMC (250 mL) fue operada por lotes y alimentada con agua residual cruda (TRH = 12 h) o con el efluente del reactor RAFA (TRH = 6 h). Se encontró que la remoción de materia orgánica en el sistema acoplado RAFA-CMC (88 % en demanda química de oxígeno (DQO), 75 % de carbono orgánico total (COT) y 79 % de sólidos suspendidos totales (SST)) fue superior a los niveles observados en el reactor RAFA (76 % DQO, 66 % COT y 73 % SST) y en la CMC (60 % DQO, 53 % COT y 40 % SST) cuando estos fueron operados de manera individual. La mayor densidad de potencia obtenida con la CMC fue de 176 mW/m 2 , utilizando una resistencia de 1000 Ω, en tanto que la eficiencia coulómbica fue de 8 %. El sistema RAFA-CMC demostró ser una buena alternativa para el tratamiento de agua residual y la generación simultánea de electricidad aún bajo condiciones de limitación de sustrato, es decir, con baja concentración de materia orgánica en el influente.Key words: anaerobic digestion, organic matter removal, coupled system, power density, coulombic efficiency ABSTRACTThe performance of a system consisting of an up-flow anaerobic sludge blanket (UASB) reactor and a microbial fuel cell (MFC) for the treatment of low-strength wastewater and the recovery of energy was evaluated. The UASB reactor (1 L) was continuously fed with raw domestic wastewater under hydraulic retention times (HRT) of 12 and 6 h. The MFC (250 mL) was operated in batch mode and fed with either raw wastewater (HRT = 12 h) or the effluent from the UASB reactor (HRT = 6 h). It was found that the removal of organic matter by the coupled UASB-MFC system (88 % chemical

Microbial fuel cell (MFC) that was configured with the carbon felt electrode and the cation exchange membrane, and inoculated with mixed culture was demonstrated to yield bioelectricity. The cell was operated under four external loads with pHs ranging from 4 to 10 and the total cell operation was monitored up to 25 days. The presented results revealed that the potentiality of maximum current and power production was achieved while hexacyanoferrate(III) used as a cathodic reaction and at neutral pH condition of media. The maximum current density 2.5 Am -2 and power density 1410 mWm -2 were observed on the 25 th day at an anode potential of -378 mV. Stable and steady power was produced by MFC on the day 22 nd to 25 th when cell operated at 250 Ω external load. The internal resistance of the fuel cell was decreased with the increase of the operation time. Coulombic efficiency (CE %) was found 22.70 % at the stable phase of fuel cell operation.

Microbial fuel cells (MFCs) have recently been used to alter different sources of substrates to produce bioelectricity. MFCs can also be used for wastewater treatment and electricity generation simultaneously. Sulfur compounds such as sulfides commonly exist in wastewater and organic waste. In this study a dual chamber MFC was constructed for power production. Sulfide was used as the electron donor in the anaerobic anode compartment. A mixed culture of microorganisms was used as an active biocatalyst to convert the substrate into electricity. The obtained experimental results illustrated that the MFC can successfully alter sulfide to elementary sulfur while generating power. The initial concentration of sulfide in the anode compartment was 0.4 g l -1 and it was completely removed after 3 days of MFC operation. The influence of oxygen was examined in the cathode chamber and the cell voltage gradually increased during aeration, reaching 480 mV after 1200 s. Hexacyanoferrate was added to the cathodic solution in different concentrations and its effects were investigated. The maximum generated voltage, power and current density were 988.9145 mV, 346.746 mW.m -2 , 1285.64 mA.m -2 , respectively and they were obtained in the presence of 1.4 g l -1 of mediator.
