Resumo
Brazil is one of the largest producers of ethanol in the world. However, during the process of ethanol
production, large quantities of vinasse are generated which can be harmful to the biota due to its
physical and chemical properties. Thus, there is a growing interest in identifying new processes for
its treatment. Microbial fuel cells (MFC) are bioreactors whose technology has been considered
promising for the treatment of biodegradable waste and simultaneous production of clean and
sustainable energy. In this context, our study evaluated the possible application of a double
chamber MFC for the vinasse treatment. We observed a reduction in chemical oxygen demand
(COD) of 58.8%, and a current density of 330 mWm-2 in a period of 28 days. Taking into
consideration our preliminary results, we concluded that the MFC technology presents itself as
highly promising for the treatment of vinasse. However, further studies on the configuration and
operation of the MFC are required for a higher number of cycles.
