英文摘要	In this paper, a modified multiple effect distillation (MED) system will be studied for a minimal water footprint in the Algerian desert, as to preserve the aquifer and for a sustainable use of this later. In fact, the water footprint is the most important factor to take into consideration in the treatment of the brackish underground water in the Algerian desert to preserve this unique source of water. The modification of MED system consists on the change of the last water condenser of the unit for a hybrid condenser (water and air condenser). For this purpose, a MED system is studied for its high recovery ratio for brackish water treatment, its flexibility with different salt concentrations, its low thermal energy need, and its robustness. The results show that the introduction of a hybrid condenser in the system allows a minimal water footprint, which is expressed by the cooling water ratio running from 4 to 18 times less than a standard water condenser system. This new configuration is applicable for a top brine temperature ranging between 75 degrees C to 100 degrees C. Otherwise, for low-temperature MED, the total heat area of the system would reach twice the total heat area of a standard MED system. Finally, a nine effects standard MED system rejects six times the feed water quantity at a higher temperature than that of the aquifer's from the last condenser and 4%-10% of brine. Whereas, the modified MED system will reject only 4%-10% of the brine at the end of the process and zero cooling water, which is a satisfactory result for a sustainable exploitation of the aquifer.
