Humedales artificiales con celdas de combustible microbianas (CW-MFC): Avances y futuras direcciones

Abstract

Resumen Los humedales con celdas de combustible microbianas (CW-MFC, por sus siglas en inglés) son sistemas que han tomado gran relevancia en los últimos años, debido a su gran capacidad para generar energía y tratar las aguas residuales. Desde el 2012 que fue el primer estudio detallado de esta tecnología, diversos autores han encontrado grandes eficiencias en la remoción de contaminantes, con valores promedio reportados de 88% para la demanda química de oxígeno (COD, por sus siglas en inglés), 75% para la demanda bioquímica de oxígeno (BOD, por sus siglas en inglés), 85% para nitrógeno total y 80% para el fosforo total, estos resultados evidencian que los CW-MFC son capaces de eliminar de manera eficiente tanto materia orgánica, principales responsables del deterioro de la calidad del agua. De forma complementaria, el acoplamiento del proceso biológico con la conversión electroquímica permite que, durante la degradación de los contaminantes, los sistemas CW-MFC produzcan energía eléctrica. En este sentido, diversos estudios reportan valores de densidad de potencia, densidad de corriente, voltaje y resistencia interna en rangos de 3.20–17.46 mW·m⁻², 25–26 mA·m⁻², 165–569 mV y 210–397 Ω, respectivamente, confirmando su viabilidad como sistemas generadores de bioelectricidad. Dichos resultados alientan a la búsqueda de nuevas configuraciones, materiales y diseños que permitan mejorar la producción de energía y la remoción de contaminantes. Abstract Constructed wetlands coupled with microbial fuel cells (CW-MFCs) have gained significant relevance in recent years due to their dual capability to generate energy while treating wastewater. Since 2012, when the first detailed study of this technology was reported, numerous authors have demonstrated high contaminant removal efficiencies, with average values of 88% for chemical oxygen demand (COD), 75% for biochemical oxygen demand (BOD), 85% for total nitrogen, and 80% for total phosphorus. These results indicate that CW-MFCs are capable of efficiently removing both organic matter, which are the primary contributors to water quality deterioration. In addition, the coupling of biological processes with electrochemical conversion enables CW-MFC systems to generate electrical energy during pollutant degradation. In this regard, several studies report power density, current density, voltage, and internal resistance values within the ranges of 3.20–17.46 mW·m⁻², 25–26 mA·m⁻², 165–569 mV, and 210–397 Ω, respectively, confirming their viability as bioelectricity-generating systems. These findings encourage further exploration of new configurations, materials, and designs aimed at enhancing both energy production and contaminant removal performance.
