Bioreactors

In air pollution control, bioremediation is the use of bacteria and fungi to consume pollutants from an air stream contaminated with organic compounds that are soluble in water or can be solubilized in water. Bioremediation also includes chemical transformation for some inorganic compounds like sulfides and nitrogen oxides.

3.1 Device Types

Biofilters, biotrickling filters, aerobic digesters, and bioscrubber technologies include a wide range of methodologies that are applicable to a diverse spectrum of air-quality applications. Each device type has advantages and limitations. These will be described below.

This chapter also describes recent breakthroughs in bioreactor technology and the combination bioreactors with other ...
