Abstract: Three laboratory-scale moving bed biofilm reactors (MBBR) with different carrier filling ratios rangingfrom 40% to 60% were used to study the effects of carrier-attached biofilm on oxygen transfer efficiencyThese results were compared to αSOTE of wastewater with a clean carrier (no biofilm attached).conditions, αSOTE decreased by approximately 70% as compared to αSOTE of wastewater at a different carrier-fillingThis indicated that the biofilm attached to the carrier had a negative effect on αSOTE.
