MODELLING AND DESIGN OF BRINE OUTFALL DISCHARGES: CASE OF A DESALINATION PLANT IN MEDITERRANEAN
In the various actions of desalination plant Project, the one to which it attaches great importance from an environmental point of view, is the waste discharge of brine poured in marine and coastal environments, since it is about of a continuous waste of significant flow with important salinity. This salinity difference conditions the environmental salinity behaviour. To determine this behaviour, the effluent dispersal poured by underwater outfall has again been studied. In order to reach this aim, dilution characteristics of the future outfall have been evaluated and concentrations of rejected brine under worst case conditions have been estimated. Also, it has been carried out the analysis of various design alternatives which allow improving efficiency of the waste management in order to increase dilution of brine. With of view to meeting this study, the CORMIX model has been of a significant contribution and Delft-3D-Flow as an audit model.
