Tracer Studies for the Modelling of Sedimentation Tanks Etudes de traceurs pour la modélisation de bassins de décantation

The flow in stormwater tanks has a major impact on their treatment efficiency. A measurement method and an evaluation method was developed to identify unfavourable flow conditions in existing sedimentation tanks. The data base is provided by mobile, event-controlled measurements of tracerbased hydrographs. The analysis is based on transfer functions known in system theory. The model parameters ...
