Abstract:

The application of process modeling to aerated facultative lagoons is demonstrated through case studies investigating 1) the benefit of bioaugmentation for extending the period of seasonal nitrification 2) the effect of sludge deposits on ammonia load, and 3) the effect of sludge deposits on BOD load. The base model used to mimic lagoon behavior in each investigation is comprised of a two-compartment transport model that accounts for interactions between the water column and sludge deposits and a reactive model based on the BioWin comprehensive ASDM model. A modeling approach and calibration procedure is applied based on a case-by-case basis.
