6.7–8 kWh/m 3 , which is much lower than that of multi-stage flush distillation (51.7 kWh/m 3 )<br />

<strong>and</strong> multi-effect distillation (45 kWh/m 3 )(80). The energy consumption keeps decreasing to<br />

3–5 kWh/m 3 by installation of energy recovery systems (81), <strong>and</strong> by the application of high<br />

rejection <strong>and</strong> high flow membranes to RO plants (82). As recently reported, the specific<br />

energy consumption can even drop down to as low as 1.6 kWh/m 3 in large-scale seawater RO<br />

plants with energy recovery devices (83). Whereas, the energy consumption of small-scale<br />

RO desalination plants (
