Abstract

Constructed wetland (CW) is a potential technology that can treat wastewater. Microbial Fuel Cells (MFCs) are devices that use bacteria as a catalyst to oxidize organic and inorganic materials and capable of generating electricity. The new approach of combining MFCs into CW is known to improve the performance of CW. Research on Constructed Wetland - Microbial Fuel Cells (CW-MFCs) has increased rapidly in recent times. The CW-MFCs is worthwhile as it has great potential to treat wastewater and to produce electricity. However, sustainable operation and application still be a challenge. Therefore, this paper aims to update the newest research development in CW-MFCs so that it can inspire a sustainable solution to make CW-MFCs feasible to be applied in the field. This study also uses a bibliometric approach to analyze the development of CW-MFCs research in the world. Hence, this paper defines CW-MFCs, the design and operational discussion, and also future research suggested improving the sustainability of CW-MFCs.
