This research plan will evaluate three microbial fuel cells (CCM) operated in continuous flow fed sanitary sewer, checking the capacity of power generation and removal of carbonaceous matter simultaneously. The use of three CCM will determine how the characteristic of each CCM can constructively interfere with the performance of each reactor and will also explore the possibility to adapt sewage treatment plants that employ existing processes such as UASB and activated sludge to generate electricity. As the process variables will be considered the TDH, the temperature and the number of electrodes to which the experimental design was adopted to duplicate the center point. Will be measured as parameters (COD, BOD, alkalinity, nitrogen series, a series of solids, redox potential, pH, volatile organic acids, conductivity and phosphorus). It is also intended to verify the morphology of the microbial communities present in CCM, enabling to observe that favor the better energy substrate. The efficiency in power generation will be monitored continuously by a data acquisition system connected to a meter in which you can apply multiple resistances to be generated graphs of polarization to evaluate the performance of each cell. Finally, we will use the response surface method to optimize the power generation and COD removal.
