  • Bioscrubber;

  • VOC;
  • biological air treatment


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. This process is particularly applied to remove volatile organic compounds (VOCs) and/or odorous molecules present in industrial gaseous emissions. The contaminant concentrations range from above 1 g m-3 to very diluted pollutants present in the gas stream (a few mg or μg m-3 for air flow rates between a few m3 h-1 and 100,000 m3 h-1, or even more for some systems). The objective of this chapter is to present the general operating methods and some applications of gas stream treatments, especially the removal of volatile organic or inorganic compounds, by bioscrubbers: i) Principles of a bioscrubber and general operating conditions, ii) Biotreatments of pollutant families, iii) Treatment of by-products generated by this waste gas treatment process.
