Estimation of VOCs and semivolatiles emission rate from an intermittently aerated bioreactor

The activated sludge process is widely employed to treat municipal and industrial wastewater. The common design considers a continuous, constant flow-rate wastewater stream and a corresponding continuous air supply. Recently, intermittently aerated bioreactors, such as the sequencing batch reactor (SBR), have found great potential for more efficient wastewater treatment. A transient model considering the emission rate of volatile and semivolatile organic compounds from an intermittently aerated bioreactor is developed and solved analytically. If the aeration time is relatively short, and/or the overall mass transfer resistance is high, a large deviation can occur from the pseudo-steady-state mass transfer model by Chern and Yu or from the conventional ASCE standard model by Matter-Mueller et al.
