Abstract
The performance of a system consisting of an up-flow anaerobic sludge blanket (UASB) reactor and a microbial fuel cell (MFC) for the treatment of low-strength wastewater and the recovery of energy was evaluated. The UASB reactor (1 L) was continuously fed with raw domestic wastewater under hydraulic retention times (HRT) of 12 and 6 h. The MFC (250 mL) was operated in batch mode and fed with either raw wastewater (HRT = 12 h) or the effluent from the UASB reactor (HRT = 6 h). It was found that the removal of organic matter by the coupled UASB–MFC system (88 % chemical oxygen demand (COD), 75 % total organic carbon (TOC) and 79 % total suspended solids (TSS)) was higher than the levels obtained by the UASB reactor (76 % COD, 66 % TOC and 73 % TSS) and the MFC (60 % COD, 53 % TOC and 40 % TSS) when these were operated individually. The highest power density obtained in the MFC was 176 mW/m2 with 1000 Ω resistance, whereas the coulombic efficiency was 8 %. The UASB-MFC system proved to be a good alternative for the treatment of wastewater and the simultaneous generation of electricity even under substrate limiting conditions, such as low concentration of organic matter in the influent.

Physicochemical treatment (coagulation-flocculation-Fenton) of mature leachates from Tuxtla Gutierrez, Chiapas landfill
Nájera Aguilar, H.A.; Vázquez Sánchez, R.A.; Gutiérrez Hernanadez, R.F.; Bello Mendoza, R.; Rojas Valencia, M.N. (University of Canterbury. Civil and Natural Resources Engineering, 2011)Mature leachates are a significant cause of soil and water contamination because they contain high organic loads of recalcitrant materials. The application of a physicochemical process is normally insufficient to remove ... -
