Industrial Biofilter Design for Removal of Hydrogen Sulphide (H2S) from Wastewater Treatment Plants

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. <br>
