Biofilter Model for Robust Biofilter Design: 1. Adsorption Behavior of the Media of Biofilter

Enhanced Biofilter Design for Consistent Odor

Biotilters are recognized by an increasing number of state air quality regulatory agencies as ”best available control technology” (BACT) for treatment of volatile organic compounds (VOCs) and odor. This has been the case for two cocomposting facilities permitted by Bedminster Bioconversion Corporation in Cobb County, Georgia, and Marlborough. Massachusetts. Both areas are in ozone non-attainmen...

Nanoporous Membrane for Immunoprotection Biofilter

Comparison of Biofilter Residence Time

Residence time is a critical factor in determining the size of an open face biofilter. Four test biofilters were constructed with media comprised of yard waste compost and brush chips to compare 8 s. and 4 s. residence time. Biofilter performance was monitored for ten months by measuring pressure drop, moisture content, odor threshold, hydrogen sulfide, and ammonia concentrations. Odor reductio...

Hydrogen Sulphide Removal Using a Novel Biofilter Media

Air emissions from waste treatment plants often consist of a combination of Volatile Organic Compounds (VOCs) and odors. Hydrogen sulfide is one of the major odorous gases present in the waste emissions coming from municipal wastewater treatment facilities. Hydrogen sulfide (H2S) is odorous, highly toxic and flammable. Exposure to lower concentrations can result in eye irritation, a sore throat...

Analysis of a Recent Biofilter Model for Toluene Biodegradation

This paper investigates and provides a critical analysis of the toluene biofilter model developed by Li and De Visscher. The model simulation results have been reproduced and compared with several sets of experimental data from literature. Three different model variations are considered: model with no substrate inhibition, with substrate inhibition, and with air flow rate modification. A sensit...
