Sewage treatment plants can emit significant quantities of volatile organic compounds (VOCs) and toxic air contaminants, but emission control by conventional methods has been difficult to achieve. The biofilter technology developed in a previous contract can satisfactorily control emissions from these plants and possibly from other sources of high-volume, low-concentration emissions such as landfills. The purpose of this study was to determine process design parameters and constraints so that this technology can be successfully commercialized. The study was conducted by the University of California, Davis.
