Reverse osmosis desalination plants (RODP) located in many arid or semi arid Greek islands consist a solution to the problem of water scarcity by supplying with fresh water the local population. However, the constant discharge of large quantities of brine into the sea may cause harmful effects on marine flora and fauna due to excess salinities. These effects can be avoided by selecting properly the configuration and location of the water outfall system of RODP via the performance of a

In the present work, (1) the mixing processes, the types of brine discharge outfall and the existing regulations for brine discharge salinity are presented, (2) these outfall configurations are compared in a fictitious case of brine discharge from a RODP regarding the achievable mixing (dilution) in the near and intermediate field region using the CORMIX model, and (3) an integrated modelling procedure for the performance of hydrodynamic studies for brine effluents from RODPs is presented which couples the near field CORMIX-CORJET model with the far field model FLOW-3DL.
