ABSTRACT
This chapter focuses on the varying types of Bio-Electrochemical System systems, such as Microbial Fuel Cells (MFC), Microbial Electrolysis Cells, Microbial Desalination Cells, and Microbial Electrosynthesis Cells. Microbial Fuel Cell (MFC) is a device that uses microbes or bacteria as biocatalysts to produce electricity via chemical reactions. MFCs offer many potential advantages over other means of localised power generation. MFC is very valuable as there are many advantageous applications in reducing pollution and cost of wastewater treatment in a sustainable and environmentally friendly way. In breweries and food manufacturing industries, waste can be treated by MFCs because of their organic-rich wastewater compounds that can serve as food for microorganisms. Sewage wastewater can also be exchanged through MFCs to decompose the organic waste contained within it. The primary concern of all researchers is to produce cheap MFCs with compact designs. Microbial electrolysis cell is theoretically related to MFC technology, which was initially introduced in 2005.
