This paper presents a technical and economic study of a small scale of Multi-Stage Flash - Recycle Brine (MSF-BR) desalination plant, which is driven by the waste heat energy of Co-generator CHP (1.6 MWel), it provided about 1.6 MWth to produce 383 m³/day. Applied with a simple mathematical model to layout MSF-BR, that has performance ≈ 8. The plant consists of 24 small-stages with BR rate about 48 kg/s and stage length vary from1.7 to 2.3 m, where the unit product cost in term of production is about 2 €/m³ and investment cost 1.4 millions €. These design features provided a great opportunity to combine a twofold purpose. The thermodynamic diagnosis is identified the design restrictions and an improved feature of different small scales of MSF-BR, those can be effectively used for small and island towns in the Middle east.
