The University of Southern California (USC), in collaboration with the County Sanitation Districts of Orange County (CSDOC), the South Coast Air Quality Management District (SCAQMD), Southern California Edison (SCE), the Water Environment Research Foundation (WERF), and Huntingdon Environmental Engineering, Inc. (HEEI), is conducting a research project to evaluate the application of biofiltration to remove volatile organic compounds (VOCs), odor-causing air pollutants, and toxics from a publicly owned treatment works (POTW) waste airstream. As part of this project, bench-scale and pilot-scale experiments are being conducted to test the effectiveness of biofiltration and determine the optimum parameters for applying biofiltration to POTWs. Results from the bench-scale experiments demonstrate that biofiltration is effective in reducing the concentration of hydrogen sulfide (H{sub 2}S) and total VOCs present in waste airstreams by over 99% and up to 90%, respectively. Average reduction of specific aromatic and carbonyl compounds ranged from 55% to 91%. Removal efficiencies for chlorinated hydrocarbons were variable, ranging from 6% to 88%. Overall, biofiltration appears to be a promising technology for full-scale implementation at POTWs for VOC and odor emission compliance.
