Process engineering of biological waste gas purification aims at the selection and operation
of biological waste gas purification technologies with the ultimate aim of assuring
mass transfer and biodegradation of one or more pollutants in a waste gas
stream. Biodegradation of the pollutants occurs when microorganisms use the pollutants
as a carbon source or an electron donor. In some special situations, microorganisms
using a particular substrate such as glucose, ethanol, etc., can also oxidize
another pollutant. This is due to unspecific metabolism by the enzymes of organisms
and is called cometabolism (Alexander, 1981). The extent to which biological
waste gas purification can occur is determined mainly by the physicochemical characteristics
of the pollutant(s), the intrinsic capabilities of the microbial physiology
and ecology, and the operating and environmental conditions.
When selecting the bioreactor technology, focus is placed on the operational and
control requirements needed to ensure an optimal chemical and physical environment
for mass transfer and biodegradation so as to achieve a high and constant removal
efficiency of the pollutant.
