Performance of sulfidogenic anaerobic baffled reactor (ABR) treating acidic and zinc-containing wastewater.
The applicability of anaerobic baffled reactor (ABR) was investigated for the treatment of acidic (pH 4.5-7.0) wastewater containing sulfate (1000-2000 mg/L) and Zn (65-200mg/L) at 35 degrees C. The ABR consisted of four equal stages and lactate was supplemented (COD/SO(4)(2-)=0.67) as carbon and energy source for sulfate reducing bacteria (SRB). The robustness of the system was studied by decr...
متن کاملPerformance of an Anaerobic Baffled Reactor (ABR) in treatment of cassava wastewater
The performance of an anaerobic baffled reactor (ABR) was evaluated in the treatment of cassava wastewater, a pollutant residue. An ABR divided in four equal volume compartments (total volume 4L) and operated at 35ºC was used in cassava wastewater treatment. Feed tank chemical oxygen demand (COD) was varied from 2000 to 7000 mg L(-1) and it was evaluated the most appropriated hydraulic retentio...
متن کاملPerformance of electrical stimulated anaerobic baffled reactor for removal of typical pollutants from low-strength municipal wastewater at low temperatures
Background: Although anaerobic system has been successfully used for treating the strong industrial wastewater, its efficiency for low-strength wastewater as municipal wastewater is not satisfying. This study aimed to enhance the capability of an anaerobic baffled reactor (ABR) for treating municipal wastewater. Methods: A 7-L ABR with 5 compartments was operated for a 287-day period fed with ...
متن کاملHybrid anaerobic baffled reactor for treatment of desizing wastewater
Polyvinyl alcohol-containing desizing wastewater discharged within final textile wastewater has a great impact to the environment due to its poor biodegradability. An improved lab-scale hybrid anaerobic baffled reactor was developed to treat desizing wastewater. The modification was achieved by increasing the height of hybrid anaerobic baffled reactor and application of proper effluent recycle ...
متن کاملCoupled Anaerobic Baffled Reactor (ABR)/Activated Sludge Treatment of Synthetic Wastewater with High Concentration of Sulfate and COD
A synthetic wastewater with high concentration of sulfate and COD was treated in anaerobic baffled reactor (ABR) coupled with an activated sludge. The work was accomplished in two phases. In the first phase, the concentration of sulfate was kept constant at 500mg/l, but COD concentration was increased from (3000mg/l to 6000mg/l), consequently, COD and sulfate removal in ABR reached to 80% and 9...
