A Method for Enhanced Control of Biomass Activity and Distribution in Biofilters

Abstract

Long-term performance of vapor-phase bioreactors can be unreliable because of uneven distribution of biomass and microbial activity throughout the bioreactors. One method to improve biomass distribution and maintain high removal efficiencies for continuous long-term use is to operate the bioreactor in a directionally-switching (DS) mode, in which the contaminant inlet is periodically switched between the top and bottom of the reactor column. The objective of this study was to evaluate the effect of DS operation on biomass distribution and activity.
