Software program for computing coulombic efficiency and power densities generated by microbial fuel cells through treating livestock slurry and wastewater.

To perform the calculations of the coulombic efficiency, areal and volumetric power densities generated by microbial fuel cells (MFCs), several procedures should be accomplished; this necessitates long period and efforts, beside the probability of committing errors. This article aims at developing a tool to support users, engineers, and specialists in performing these computations by developing a desktop software that can run on laptops and computers. A mathematical model was developed to perform the calculations. Next, a flowchart was generated, and the mathematical model was incorporated in the flowchart. Then, Microsoft Visual FoxPro 9.0 Service Pack 2.0 was implemented to configure the software by combining the flowchart, mathematical model, and interface creation. Data were obtained from government associations, wastewater treatment plants, non-governmental organizations (NGOs), and literature. The data obtained for performing the calculations in the traditional way were utilized to generate output data which were matched with the output data obtained from the software. The results of both the traditional method and the program were congruous. The software is able to calculate the coulombic efficiency, area and volumetric energy density of MFCs by processing various feedstocks such as livestock manure and wastewater. [ABSTRACT FROM AUTHOR]
