Studies on Biological Degradation of 4-Bromophenol Using Anaerobic, Anoxic and Aerobic Bioreactors

Abstract

The present study investigates biodegradation of 4-Bromophenol (4-BP) and simultaneous removal of COD in anaerobic, anoxic and aerobic moving bed bioreactors. Cow dung slurry was used as a source of microbial consortium for acclimatization in moving bed reactors in batch mode. The acclimated microbial consortium was able to degrade various concentrations such as 5, 10 and 15 mg/l of 4-BP within specific time period. Biodegradation was evaluated by determining total degradation of 4-BP and simultaneous removal of COD. Nearly 97, 90.54 and 98.99% degradation of 4-BP and 76, 60 and 85% removal of COD was achieved in anaerobic, anoxic and aerobic reactor, respectively.
