Abstract
Background: Purified terephthalic acid (PTA) wastewater from a petrochemical complex was utilized as a fuel in the anode of a microbial fuel cell (MFC). Effects of two important parameters including different dilutions of the PTA wastewater and pH on the performance of the MFC were investigated. Methods: The MFC used was a membrane-less single chamber consisted of a stainless steel mesh as anode electrode and a carbon cloth as cathode electrode. Both power density and current density were calculated based on the projected surface area of the cathode electrode. Power density curve method was used to specify maximum power density and internal resistance of the MFC. Results: Using 10-times,...

Abstract
Environmental issues are more and more considered because of increasing environmental pollution along the industrial growth. In recent years Microbial Fuel Cells (MFCs) have attracted attention of many researchers as a renewable source of clean energy. In this research, wastewaters of purified terephthalic acid (PTA) plant and polyethylene terephthalate (PET) plant were examined in MFC.
Voltage generation in the PTA MFC cycle indicated two steady phases. Produced power was 31.8 mW/m2 (normalized per cathode area) and calculated Coulombic efficiency was 2.05 % for COD removal of 74% during 21 days. Concentration changes of each pollutant indicated that acetic acid (AA) and benzoic acid...

Abstract
Wastewater of purified terephthalic acid (PTA) from a petrochemical plant was examined in a membrane-less single chamber microbial fuel cell for the first time. Time course of voltage during the cell operation cycle had two steady phases, which refers to the fact that metabolism of microorganisms was shifted from highly to less biodegradable carbon sources. The produced power density was 31.8 mW m-2 (normalized per cathode area) and the calculated coulombic efficiency was 2.05 % for a COD removal of 74 % during 21 days. The total removal rate of different pollutants in the PTA wastewater was observed in the following order: (acetic acid) > (benzoic acid) > (phthalic acid) > (terephthalic...
