GENERATION OF ELECTRICITY USING A DOUBLE CHAMBER MICROBIAL FUEL CELL
ABSTRACT
The microbial fuel cells (MFCs) was used to generate electricity from waste water and fresh water, Design MFCs using different types of materials for the electrodes on the generation of electrical power from two MFCs, operated identically with a waste activated sludge feed and understand how bacteria and other living organisms can be used to produce energy. For this set of tests, using a fresh set of substrate and distilled water without the addition of either glucose or salt, it was observed with Copper (Cu) acting as the electrode for both anode and cathode, a voltage of 0.073V was generated. Alternating the electrode in the same samples, using Copper (Cu) for the anode chamber and Aluminium (Al) for the cathode chamber, a voltage of 0.420V was generated. The BOD readings measured before and after treatment were 22ˑ32mg̸ L and 19ˑ86mg̸ L respectively, this shows that as electricity is being harnessed the wastewater is being treated simultaneously, making the MFC setup highly economically advantageous in solving the wastewater disposal problem of the environment as well as that of power (electricity). Also the conductivity of the wastewater sample was measured to be 2790μscm.For the efficiency of MFC we compare different types of electrodes and anodes to obtain different power output.
