Abstract

Paper recycling wastewater was investigated to produce electricity in a microbial fuel cell. Power output increased from 55 mW/m2 (1.6 W/m3) to 200 mW/m2 (5.7 W/m3) with the influent wastewater strength increasing from 136 mg/L to 449 mg/L while COD removal decreased from 37.5% to 27.5% corresponding to coulombic efficiencies (CEs) ranging from 22% to 33% at a hydraulic retention time (HRT) of 6 h. Power generation improved to 394 mW/m2 (11 W/m3) by increasing the ionic strength using a 50 mM phosphate buffer solution while COD removal increased to 35% and CE increased slightly to 24% with an influent COD of 449 mg/L. Changing the HRT from 6 h to 15 h led to the increase of COD removal to 38% while power generation did not change. Further increase of the HRT to 25 h only resulted in the increase of COD removal to 41% while power generation decreased to 102 mW/m2 (3 W/m3).
