In order to forecast and to follow the dispersion of odours around its treatment sites, SIAAP which treats wastewater for the entire region around Paris, developed and implemented an innovative tool called SYPROS. SYPROS is based on the 3D CFD dispersion tool Fluidyn–PANEIA and uses a Lagrangian puff model for real time calculations, together with a source definition module for determining the source emission rates in real time. In order to adjust the source emission the so–called remapping process has been implemented. A case study for the implementation of the comprehensive tool SYPROS on the Seine Aval site is described.
