Enhancing energy recovery from industrial wastewater using microbial fuel cells
… great promise for the simultaneous treatment of wastewater and electricity production. However, the electricity recovery needs improvement if MFCs are to compete with already established technologies e.g. anaerobic digestion. The aim of this study was to investigate ways of enhancing electricity …

The Effectiveness of Multiple Redox Treatment Strategies on the Treatability of a High Strength Industrial Wastewater
The treatability of a high strength industrial wastewater, 9,000 mg/L as chemical oxygen demand (COD), by three sequencing batch reactor (SBRs) systems operated under alternating redox environments: anaerobic/aerobic (ANA), anoxic/aerobic (ANX), and aerobic was investigated. A synthetic wastewater …
