Chapter 4: Activated Sludge Modelling - IqTMA-UVa

Conclusions• The Model works at constant T and pH• The composition of organic matter was assumed constantConstant stoichiometric coefficients• It does not account for N or P limitations• Constant distribution of heterotrophic populations• The type of electron acceptor does not affect biomass decay• The Model does not consider biomass settling (SRT > 3 days)• Biomass concentration should range between 750 and 7500 mg/Lto avoid settling problems• The unaerated fraction of the reactor should not exceed 50 % toavoid a deteriorated biomass settling92
