Article abstract: Reverse Osmosis (RO) desalination capacity has been increasing steadily over the years. However, the necessity of developing more efficient designs is becomes more crucial due the increased demands for fresh water. This study shows the development of a conceptual design of an efficient energy medium-scale RO brackish water desalination plant of the Arab Potash Company (APC) located in Jordan. In this regard, a photovoltaic (PV) solar farm has been combined with the original RO process generate electricity in a sustainable way and decrease the overall energy consumption. To obtain an accurate estimation of the process performance, this work shows the utilisation of an efficient process model for the spiral wound RO process. Also, an accurate model for the photovoltaic system was gathered from the literature to conduct preliminary calculations of the proposed new configuration. The simulation results of the proposed RO design are compared to the original ones of APC and showed a considerable energy saving.
