When using dynamic simulation for fine tuning of the design of activated sludge (AS) plants diurnal variations of influent data are required. For this application usually only data from the design process and no measured data are available. In this paper a simple method to generate diurnal variations of wastewater flow and concentrations is described. The(More)
The aim of this study was to obtain a validated model, consisting of the Activated Sludge Model No. 3 (ASM3) and the EAWAG bio-P module, which could be used as a decision tool for estimating the maximum allowable peak flow to wastewater treatment plants during stormwater conditions. The databases used for simulations originated from the Hanover-Gummerwald(More)
The presented method aims to improve the current practice of using design procedures based on simplified steady-state assumptions for design of WWTP, by promotion of additionally use of dynamic simulation for the design refinement. This paper describes a consistent way to parameterise a dynamic simulation model in compliance with German design guidelines(More)
