As mentioned in Chapter 3, biotreatment for air pollution control started in the 1950s using soil beds. The technology has since matured and industrial applications of biofilters are numerous. More recently research has focused on a variation of biofilters called biotrickling filter, or trickling biofilter.
WebMar 13, 2013 · Summary. Biological air treatment processes have been available for many years. Among these, biofilters (filter beds, biocatalysts), biotrickling filters and bioscrubbers are implemented. In a bioscrubber, a large number of soluble and biodegradable molecules are transferred into an aqueous phase and degraded in an activated sludge reactor. WebAug 21, 2012 · Biofilters are used to treat air from mechanically ventilated buildings that use fans to control airflow. The ventilating fans allow contaminated air to be collected and directed to a biofilter. In some …
