Constructed Wetland‐Microbial Fuel Cell: An Emerging Integrated Technology for Potential Industrial Wastewater Treatment and Bio‐Electricity Generation

Bacterial degradation is one of the main mechanisms of contaminant removal from wastewater treatment. Various wastewater treatment technologies, including constructed wetlands ( CWs ) and microbial fuel cells ( MFCs ), rely on bacterial degradation for removal of wastewater contaminants. Both technologies are currently being used independently for wastewater treatment. The MFCs require artificially made redox conditions for their implementation, while constructed wetlands have naturally occurring redox conditions. Recently, a merged technology was developed by implanting MFC into constructed wetland ( CW ), and named CW‐MFC . The proposed merged technology retains the best features of both the technologies, thus gaining a lot of attention. There is a possibility to upgrade and improve the CW technology with such merged technology for enhanced performance. This chapter aims to discuss details of this CW‐MFC merged technology and its possible application in industrial wastewater treatment.
