MFCs are reactors that collect the chemical energy found in wastewater that can be
biodegraded by microorganisms and converted into electrical energy. It can be stated that
wastewater treatment plants (WWT) are one of the important energy consumers. Therefore,
with the development of MFC technology, WWT technology aims to transition from an energyconsuming process to an energy-generating process. In recent years, various studies have been
carried out to increase the efficiency obtained from microbial fuel cells. Reactor design is an
important parameter for MFC treatment efficiency and power generation. In this study;
domestic wastewater treatment and electricity generation were examined in nested cylindrical
dual-chamber microbial fuel cells (NDMFC). The cathode chamber is placed inside the anode
chamber to bring the electrodes closer to together the reactor and to reduce the internal
resistance. The reactor was operated at 20oC temperatures and a pH 7,50. The anode and
cathode chamber was separated by Nafion 117 membrane. This experiment ended 14th day
because voltage values decrease rapidly. At the end of the experiment, the highest voltage and
power density values were obtained 267,9 mV and 21,948 mW/m2 respectively. Furthermore,
%89 COD removal was achieved. Considering these results, it is clear that reactor design for
wastewater treatment and electricity generation in microbial fuel cells is important for COD
removal and electricity generation.
