Microbial fuel cell (MFC) systems, which have been tried as an alternative technology in wastewater treatment for the last decade, have become more and more important because they are sustainable systems that can meet their own energy needs and obtain electrical energy. Although microbial fuel cell systems are based on, this project, which is completely different from the products designed before, aims to provide electricity production by utilizing the transfer of electrons (extracellular electron transfer) obtained by oxidizing organic substances by anaerobic bacteria in soil or sediments. In this energy production, green algae that provide mutual polarization with the oxygen ion they produce served as a biological pump and took part in the cleaning of water. The materials to be used were determined as sediment, green algae culture, domestic wastewater, acetate to be a energy source for bacteria, H + ion-permeable membrane, carbon paper and platinum wire. Also some chemicals have been used for algae culture and to make ready to use the H+ ion membrane. In order to determine the most efficient version of the project, voltage measurements were made at certain intervals per day. In the end of measurements, it was seen that average volt of the system has produced was 42.633.With the completion of the project, a system that provides water treatment and electricity generation at the same moment, which is a first among MFC systems, was obtained. Thus, alternative energy source design has been successful and a completely new product has emerged that can be a solution to environmental pollution.
