Performance of anaerobic fixed film down-flow reactor for spent wash treatment

    Research output: Contribution to journalArticlepeer-review


    The performance of a bench scale ‘anaerobic fixed-film down-flow bioreactor’ with glass bead as a packing material for treatment of high strength wastewater (spent wash) in terms of percent Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD) removal at various temperatures has been studied. The reactor is operated at temperatures ranging from 35oC to 51oC for hydraulic retention time (HRT) of 15 days. For this hydraulic retention time, experimental results show that COD removal is 60-64.8 % and BOD removal is 65.3 – 70%. The maximum percent COD and BOD removal is observed at 41oC.
