title: The role of sulphidogenesis in anaerobic treatment phase of tannery wastewater treatment in advanced integrated wastewater pond system.
abstract: An outdoor experiment was conducted to study the competition between Sulphate Reducing Bacteria (SRB) and Methanogenic Archaea (MA) in anaerobic treatment phase of tannery wastewater treatment in pilot-scale Advanced Facultative Pond (AFP). The relative electron flow towards sulphate reduction was higher (59-83%) than towards methanogenesis (17-41%), although the COD recovery within the reactor varied between 15 and 90%. The results also demonstrated that the flow of electrons towards SRB increased with increase of the sulphate concentration and decrease of the COD:SO4= ratio.
