“…However, after a long period running, the maximum power density of PEM-MFC increased by 24.6%, and that of 0.45μm-SFM-MFC increase by 49.5%. These difference may be ascribed to the reason that a few days were required to reach a new steady-state current after change the buffer solutions [17].…”

Abstract-Membrane separator in microbial fuel cell (MFCs) is one of the main factors that could significantly affect the performance of MFC. Proton exchange membranes (PEMs) are typically used in two-chamber microbial fuel cells to separate the anode and cathode chambers while to allow the transfer of protons from anode to the cathode. However, protons will accumulate in the anode chamber, and therefore and the pH balance will be broken if the MFC works for a long time. In this study, effects of two types of separator membranes (Proton Exchange Membrane; 0.45μm Synthetic Fabric Membrane) on the pH spitting and MFC performance were investigated. Membrane internal resistance, membrane biofouling and oxygen diffusion were also analyzed. The fouling layer attached on membranes consisted of microorganisms was demonstrated from imaging analysis coupled with SEM. We found that pH splitting might influence MFC internal resistance more than biofouling. This was attributed to the proton transfer process, which was influenced by cathode pH value.

“…The variation of Dissolved oxygen with time is depicted in Fig 7. Results showed that dissolved oxygen increased from 2.5 mg/L to 4.2 mg/L. The reason for increase in the Dissolved oxygen of waste water sample is due to decrease in the levels of BOD and COD in the waste water sample and aeration [18][19][20][21][22][23][24][25][26][27]. …”

“…The effect of Microbial Fuel Cell on BOD of the waste water sample is illustrated in the below Fig 8. Results showed that BOD has decreased from an initial value of 560 mg/L to a final of 220 mg/L. The decrease in BOD is due to continuous aeration and the action of sludge [28][29][30][31][32][33][34][35][36][37].…”

“…COD of the waste water sample at different time intervals are presented in the below Fig 9. Results shown that COD of the waste water has decreased from an initial of 1050 mg/L to 450 mg/L because the organisms in the waste water have grown and degraded the organic matter in waste water sample. The waste water showed its potential for COD removal indicating the function of microbes present in wastewaters in metabolizing the carbon source as electron donors [38][39][40][41][42][43][44][45][46][47]. …”

Eco system is deteriorating day by day due to Industrial effluents. The effluents are containing toxic chemicals which are inturn polluting ground drinking water and creating new diseases. Treatment methods for these Industrial effluents are becoming more costly. The Present study is aimed and focused at decreasing the toxicity of Industrial waters and the target is Reduction, Recycle and Reuse (RRR) using Microbial Fuel Cell. Microbial Fuel Cell experiments were carried out in batch operations for Appughar waste water using Bakers yeast (saccharomyces cerevisiae organism) in order to increase oxygen levels and decrease toxicity. The parameters studied are design of MFC, NaCl concentration, Agar concentration, fructose dosage, pH, COD, BOD, DO, TSS, TDS, Sulphates, Chlorides and Power generation. The results produced have high oxygen levels and change of pH is appreciable from 7.8 to 7.0. COD, BOD and DO have changed from 1050 to 450 ppm, 560 to 220 ppm and 2.5 to 4.2 ppm.

“…The electrons thus produced are transferred to a terminal accepter such as O 2 , nitrate and sulphate. These terminal electron accepters are get reduced by these electrons [16,17]. A new product is found which can leave the cells when terminal electron acceptors are diffused into the cells.…”
