Abstract

The secondary settling tanks (SST) often prove to be the bottleneck of the whole activated sludge wastewater treatment process. Therefore, when using computer simulation for the design and optimal operation of wastewater treatment plants, the SST model has to be selected adequately besides the model describing the activated sludge process. For this reason, six SST models are introduced and compared in this study using the framework of the Simulation Benchmark developed by the COST 682 group. The Takács-model is described in the Benchmark in detail, combination of it with the Härtel-Pöpel correction function is investigated is this study. The models of Otterpohl and Dupont having three component fractions, the model of Hamilton which adds a diffusion term to the convective process description and a reactive SST model are also simulated and analysed in this contribution.
