Microbial Fuel Cell (MFC) in treating spent caustic wastewater: Varies in Hydraulic Retention Time (HRT) and Mixed Liquor Suspended Solid (MLSS)

The performance of an anoxic-aerobic MFC reactor operated with spent caustic wastewater was studied at different HRT and MLSS. Spent caustic wastewater is the industrial wastewater with high COD concentration influenced by its high sulfur content, high salinity and high alkalinity. Little is known on the MFC capacity in treating spent caustic wastewater, therefore the present study employed spent caustic wastewater as the feed wastewater. The...
