    Modeling of sulfide emission from the Virginia sewer system
    (2001) Lu, Yue; Loewenthal, Richard Eric; Alexander, Mark Gavin
    Recognizing that attack in the sewer environment invovles five distinct processes occurring simultaneously, each with its own kinetics, any meaningful research can be effected only once the individual processes have been uncoupled and studied separately. The principal objective of this thesis is to predict hydrogen sulfide emission from sewerage along the line of flow for the Virginia sewer field laboratory. Meeting this objective required both an understanding of the flow hydraulics in this sewer environment, and a model (kinetic equation) for hydrogen sulfide emission in terms of the flow characteristics. This thesis presents the relevant theory for predicting hydraulic characteristics (including velocity gradient, G) in gravity flow sewers.
