ABSTRACT:
With the increasing standard of living, the energy consumption increases as well. So, waste production, like wastewater, increases as well too. One of wastewater is wastewater from yeast industry. Wastewater from this industry has not only a high pollutants load but are produced in great amounts as well. Technical device that can accomplish the wastewater treatment and electricity production from wastewater is a microbial fuel cell. In microbial fuel cells activated sludge bacteria can be used for electricity production during wastewater treatment. The possibility of using the Cu-B alloy as cathode catalyst for microbial fuel cells to wastewater treatment of wastewater from yeast industry is presented in this paper. The reduction time for COD with the use of microbial fuel cell with the Cu-B catalyst (with 5, 10 and 15% amount of B) is similar to the reduction time with aeration. The obtained power (4.1 mW) and amount of energy (0.93 Wh) are low. But, if can accept a longer COD reduction time, the obtained amount of energy will allow elimination of the energy needed for reactor aeration.
