Sulfonated poly (ether ether ketone) (SPEEK) membranes and their modifications are viewed as arguably the most promising in microbial fuel cell (MFC) applications due to their non-fluorinated base, superior chemical stability, and lower costs compared with Nafion membranes. In this work, SPEEK membranes with different degrees of sulfonation (DSs) (60 to 76 ) and blended with charged surface modifying macromolecule (cSMM) were used as electrolytes in an MFC for simultaneous electricity generation and wastewater treatment. RESULTS: Performance evaluation of newly fabricated membranes was carried out and was compared with that of Nafion 117. The MFC with SPEEK76/cSMM generated about 16.5 higher maximum power density (172.1 mW m-2) than that with Nafion 117 (143.7 mW m-2). In addition, the SPEEK76/cSMM exhibited the highest coulombic efficiency (CE) of 17.6 , which was 21.6 higher than that of Nafion 117 (13.8 ). Chemical oxygen demand (COD) removal of all characterized membranes was above 80 in our particular MFC. CONCLUSION: MFC is a suitable method for simultaneous wastewater treatment and electricity generation. SPEEK76/cSMM is a promising membrane to be applied in MFC.
