The diurnal flux in the dispersion of sewage plant odors

This study used a Gaussian plume dispersion model to analyze the diurnal flux in odors emanating from a sewage treatment facility in Lincoln, Nebraska. For each test day, eight sets of meteorological observations taken every 3 h were utilized in the computations. Input data included both January and July measurements to facilitate seasonal comparisons in the daily flux of odors. The odor problem appeared to be more severe in January when compared to July, and distinctive diurnal patterns were uncovered for both months. The implications of the results are discussed, and suggestions for further research are presented.
