Abstract :

  Article abstract The Reverse Osmosis (RO) system has confirmed its viability to produce high quality water from brackish water sources. However, the increase in water and electricity demands and has raised the necessity of a sustainable and integrated water treatment systems. Renewable sources of energy can be applied to reduce the environmental footprint and satisfy the energy demand. An integrated system of wind energy and largescale RO system has been proposed in this paper to generate freshwater from brackish water. A generic model of the multistage multi pass RO system of Arab Potash Company (APC) was dedicated with a set of algebraic equations for wind turbine operation to form an accurate model to compute different performance indicators including total energy consumption. The energy analysis was carried out for each individual and the integrated systems and estimating the total generated power from the wind turbine for one year (July/2019 to July/2020). In this regard, the power for the high-pressure pumps of the RO system has been supplied from the grid and the wind energy system. The results show that the integrated wind – RO system attain a maximum energy saving during the windy months. Overall, the wind turbine system has enhanced the reduction of total required power of RO system compared to a grid powered RO system.
