Stable Voltage

Microbial fuel cells (MFCs) are devices that exploit microorganisms as biocatalysts to degrade organic matter or sludge present in wastewater (WW), and thereby generate electricity. We developed a simple, low-cost single-chamber microbial fuel cell (SCMFC)-type biochemical oxygen demand (BOD) sensor using carbon felt (anode) and activated sludge, and demonstrated its feasibility in the construction of a real-time BOD measurement system. Further, the effects of anodic pH and organic concentration on SCMFC performance were examined, and the correlation between BOD concentration and its response time was analyzed. Our results demonstrated that the SCMFC exhibited a stable voltage after 132 min following the addition of synthetic WW (BOD concentration: 200 mg/L). Notably, the response signal increased with an increase in BOD concentration (range: 5–200 mg/L) and was found to be directly proportional to the substrate concentration. However, at higher BOD concentrations (>120 mg/L) the response signal remained unaltered. Furthermore, we optimized the SCMFC using synthetic WW, and tested it with real WW. Upon feeding real WW, the BOD values exhibited a standard deviation from 2.08 to 8.3% when compared to the standard BOD5 method, thus demonstrating the practical applicability of the developed system to real treatment effluents.

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.

Abstract - The need of energy in Indonesia was increasing and encouraging to develope some efficient   renewable   technology   and   environmental   friendly   researches.   One   of   the alternative energy that can be used is Microbial Fuel Cell (MFC). Microbial Fuel Cell (MFC) works by using microorganisms to degrade organic compounds that can generate electrical energy.   Several   studies   have   been   conducted   on   Single   Chamber   MFC.   In   this   study, conducted to determine the effect of wastewater treatment through Stack Microbial Fuel Cell (MFC) on current producing. The system used carbon brush electrode, Proton Exchange Membrane (PEM) as cation exchanger, tofu liquid waste as source of substrate, and bacterial isolated tofu liquid waste as degrading organic substrate, that has known in system's ability to generate electrical energy as well as reduce COD value. Optical Density (OD) value was measured to determine the metabolic activity of bacteria, with wavelength 570 nm. The research showed that Microbial Fuel Cell (MFC) that lasted for 72 hours resulted potential of electrical current  0.96 mA at  Stack MFC and Blank 0,43 mA.  The acquisition of electric current Stack MFC was greater than Blank Single Chamber. In addition, it also decreased Chemical Oxygen Demand (COD) value in the range of 28-38%. Keywords -  Chemical Oxygen Demand, Current, Microbial Fuel Cell , Stack MFC, Tofu liquid waste

High Chemical Oxygen Demand

To investigate the performance of microbial fuel cell (MFC) with a single-chamber membrane, Pseudomonas aeruginosa is used as a bio catalyst for various synthetic wastewaters rich in carbohydrate and is compared with real dairy wastewater in this experiment. Therefore, the choice of appropriate carbon, nitrogen, NaCl, inoculum content, temperature, and pH process parameters are used for preparing synthetic wastewater was agreed upon by one-variable-at-a time approach. Maximum levels of voltage generation attained from the synthetic wastewater was 485 mV when supple­mented with 1.5 % of lactose as a source of carbon, 0.3 % of ammonium chloride as a decent nitrogen source, 0.03 % of NaCl, inoculum concentration of 3 %, the temperature at 37 oC and pH 7. On the other hand, the maximum voltage attained with real dairy wastewater was 561 mV with high chemical oxygen demand (COD) value of 801 mg l-1. The maximum power density obtained from dairy wastewater was 73.54 mW m-2. Thus, High voltage achieved for MFC operating with real dairy wastewater suggests that it can be used not only for the industrial application to generate more renewable power, but also for the wastewater treatment carried out at the same time.
