IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

ACTIVATED SLUDGE MODELLING WITH SMOOTHED PARTICLE HYDRODYNAMICS
Author : MICHAEL MEISTER , CHRISTOPH BERGMEISTER , DANIEL WINKLER & WOLFGANG RAUCH
In this work a novel wastewater treatment model based on smoothed particle hydrodynamics is proposed. To account for the biokinetic processes the activated sludge model (ASM) number 1 is used. Since the local hydrodynamics are neglected in the original model, ASM1 is coupled to the wastewater hydraulics, which are simulated with weakly compressible smoothed particle hydrodynamics. In the aerobic reactor the stirrer induced mixing of the biokinetic compounds is modelled with external forces. In the anoxic reactor the bubble induced mixing is described by a novel multi- fluid formulation, which allows for resolving the collective movement of rising air bubbles at a coarse resolution of 4 to 8 SPH particles per bubble. With the new algorithm the simulation times of biokinetic processes can be attained and hence we present results for a full scale treatment plant simulation conducted with the coupled solver.
