Microbial Fuel Cell (MFC) have the potential to provide energy reuse within bioloigal treatment processes and reduce carbon footprint. This paper discusses use of MFCs in wastewater processes, methane production, desalinations, power supply and other advantages. The overall econonic advantages of MFCs are estimated....

Microbial desalination cells used a pretreatment for seawater RO can reduce salt content between 50-70%. The pretreatment step is self-powered because of the energy created in the cell. An energy savings of 7 kW-hr/1000 gallons would save a 1 MGD RO facility $200,000 per year....
