The role of sulphidogenesis in anaerobic treatment phase of tannery wastewater treatment in advanced integrated wastewater pond system.
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.
