Abstract

In this study, the performance of an ANAEROBIC BAFFLED REACTOR (ABR Pilot 100 l and six COMPARTMENTs) for SULFATE removal from the wastewater from Amirkabir Industrial Estate was investigated. The reactor was started with a hydraulic retention time (HRT) of 25 h at 35°C to be gradually reduced to 3.33 h. The best reactor performance was observed at a HRT of 4 h and a SULFATE loading rate of 3.318 Kg SO4/m3.d at which the SULFATE removal efficiency was 89.15%. In this condition, the highest SULFATE removal was observed in the first COMPARTMENT (69.08%) which had the lowest PH as acidogenesis and acetogenesis had taken place in earlier COMPARTMENTs. This result demonstrated that the sulfidogenesis occurred in the acidogenic PHase. Maximum SULFATE removal (66.11%) was obtained when temperature was reduced to 20°C (HRT of 4 h). Under the same conditions, the fourth COMPARTMENT which had lowest PH level exhibited maximum SULFATE removal percent (28.98%). This indicates that decreasing temperature leads to the acidogenic PHase to shift toward the following reactor COMPARTMENTs. Also, these findings are a further indication of the ability of the acidogenic PHase for SULFATE removal.
