Bio-oxidation control of air emissions from panel board production – A new direction
Biofilters or bio-oxidation systems have been used for control of air emissions, primarily odors, since the 1960’s. Those early uses in the U.S. were largely relegated to odor control, primarily H2S, mercaptans and skatols, from wastewater treatment facilities. The Europeans were more aggressive in applying biofilter systems to various industrial air emissions, again primarily for odor control in the close confines of European communities. Many of these applications were associated with food and fragrance odors from production facilities located in highly populated areas of Western Europe. During the 1980’s and 1990’s odor emissions control using biofilters increased dramatically in North America, however, virtually all of these bio-oxidation systems were installed without specific VOC or HAP pollutant emission limits.
