Summary

Conventional packed-bed bioreactors for waste-gas treatment such as biofilters and biotrickling filters frequently encounter operational problems such as filter bed clogging, channelling, pressure drop, mass transfer issues for sparingly soluble pollutants, oxygen deficit, pH and temperature fluctuations, substrate toxicity, and transient-state operations. Recently, the better scientific understanding of the basic mechanism governing gas-phase pollutant removal in bioreactors, and in-depth analysis of different bioprocesses have paved way for researchers to develop new bioreactor configurations for waste-gas treatment. Some novel bioreactor configurations have been designed with the idea to overcome the limitations of conventional biological waste-gas treatment systems. In this chapter, the operation and performance of different novel bioreactor configurations such as planted biofilter, rotatory-switching biofilter, tubular biofilter, fluidized-bed bioreactor, airlift and bubble column bioreactors, monolith bioreactor, foam emulsion bioreactor, fibrous bed bioreactor, and horizontal-flow biofilm reactor were reviewed. Besides, a brief overview of different two-stage systems for waste-gas treatment has also been provided, combining biological and non-biological (such as adsorption, oxidation, absorption) processes.
