Oxygen Mass Transfer in Biological Treatment System in the Presence of Non-aqueous Phase Liquid

Abstract

Oxygen mass transfer is an important phenomenon in any biological treatment systems, fermentation reactors and other biochemical reactors. In biological treatment processes, aeration and agitation is carried out to enhance the oxygen mass transfer in the system, which in turn enhances the fermentation or treatment efficiency. In case of wastewater treatment plant, this process takes around 45-50% of the total energy requirement of the treatment plant. This paper proposes a new method for enhancing an oxygen mass transfer phenomenon in biological treatment processes by introducing non-aqueous phase liquids in the treatment system.
