Abstract

Wastewater treatment is an energy intensive process and sustainable processes/technologies for the treatment of wastewaters need to be considered. One such contender might be the microbial fuel cell (MFC), a subset of bioelectrochemical system (BES) which generates electricity in the process of electrogenic (generating electrons) degradation of soluble organic contaminants present in the water (or wastewater) by electrogens (electron producing bacteria) at the anode in absence of oxygen. Several issues related to the power performance (also somewhat linked to the cost) of MFCs exist causing barriers in the deployment of up-scaled MFC system and the continual research from a multitude of discipline is focusing on overcoming these issues.

Key findings

  • MFCs generate electricity through the degradation of organic contaminants by electrogens at the anode.
  • Several issues related to power performance and cost hinder the deployment of up-scaled MFC systems.
  • Continual research from multiple disciplines is necessary to overcome these issues.
