Wastewater Samples

A membrane-less and mediator-less system was designed and tested with wastewater sample as fuel to generate electricity. Microorganisms were first isolated from the wastewater sample to pure culture and were used as the ‘machinery’ that converts wastewater into energy. The wastewater samples were treated either by sterilization or non-sterilization methods. These tests were run using a modified air-cathode single chamber microbial fuel cell (MFC). By sterilizing the wastewater, the calculated power density was much lower compared to non-sterilized wastewater indicating a significant role of microbial activity in the SCMFC system and substrate availability. Furthermore, mixed culture was observed to give larger power density compared to an individual microbe (18.42 ± 5.84 mW/m2 for mixed culture and 8.82 ± 4.56 mW/m2 to 9.46 ± 4.87 mW/m2 for individual microbe, Bukholderi capecia and Acidovorax sp. respectively) to prove that larger power value could be achieved with a mixed microbial system. In addition, the system proved to remove 68.57% of chemical oxygen demand (COD) of the wastewater sample tested. In conclusion, the designed SCMFC has been proven capable of power generation and wastewater treatment comparable to other SCMFCs to date.

Chocolate Industry

Microbial Fuel Cell (MFC) is an efficient system for generating low power where wastewater is substrate for the biocatalyst. In this work, Annular Single Chamber Microbial Fuel Cell (ASCMFC) with spiral anode was fabricated and tested. Carbon cloth and stainless steel 400 meshes were selected as cathode and anode electrodes, respectively. In order to enhance the conductivity of anode, the graphite coating was applied. A 40% platinum as catalyst was used on carbon based cathode in MFC. The carbon cloth was coated with 5% Nafion solution. In fact Nafion acts as Proton Exchange Membrane (PEM) in the fabricated MFC. For the first time, wastewater of Chocolate industry with COD 1400 mg/L was used as substrate in anode compartment. Also a mixture of anaerobic sludge from wastewater treatment plant (Qaem-Shahr, Iran) was introduced into MFC. Maximum voltage obtained in the ASCMFC system was 792 mV in an open-circuit mode. Also, Fabricated MFC operating at 30 ◦C, the maximum achieved power density using an external resistance of 500Ω was about 4.8 W/m3. The upshots from single chamber MFC were compared to dual chamber MFC. The findings demonstrate that, due to the generated high power density and voltage by the cell, the ASCMFC has a great potential for COD removal and wastewater treatment.
