Abstract
Hydrogen sulphide (H2S) is the main odor-causing, toxic, and corrosive
chemical found in wastewater treatment operations. Bio-oxidation based processes for
air pollutant removal have become more attractive to the industry and numerous
wastewater treatment facilities have replaced conventional air treatment technologies
such as adsorption and chemical scrubbing with bio-oxidation based processes such as
biofilters. Of the three main types of air phase bioreactors, biofilter is used more
commonly than the others due to its simple configuration, ease of operation, and
economic benefits. This chapter addresses challenges in the industrial biofilter design
for H2S removal from wastewater treatment facilities. Wastewater industry
professionals, biofilter customers, biofilter vendors, and researchers who work in the
field of odor and H2S emission control and biofilter design will find this chapter very
useful.
