Transforming of Organic Materials to Electrical Power by Means of Nonpathogenic Microorganism
(Abstract Constructing and testing of a microbial fuel cell (MFC) had been accomplished in this research. Two MFC chambers connected with salt bridge had been operated and studied using synthetic waste water and real waste water as anode chamber solution. Operating temperature and pH value were investigated by changing temperature from (25 to 30 °C) and reducing pH from (6.7 to 6.5). The results revealed that increasing operation temperature had a significant effect on reducing operation time while decreasing pH improved the measured voltage and current besides reducing operation time to just five days. The cell was tested in the presence of real waste water under the best temperature and pH, and the results proved the capability of the manufacture cell in treating such contaminate material in relatively short operation time. The COD levels for the adopted experiments revealed reduction above 60% proving the ability of the living microorganisms in digesting the used substrate producing electrical power., 2018) -
