“…Robertson et al (1996) improved the operation of RO plants by introducing computer simulations for the control of an RO pilot plant. Kahdim et al (2003) developed a theoretical model to predict the performance of RO systems. They showed good agreement between the model results and the performance of two different membrane types.…”

Seawater desalination using a cost‐effective reverse osmosis system is crucial for hot climate countries suffering from water scarcity. The most favorable seawater membrane characteristics were identified under typical Egyptian operating conditions. Twelve different commercially available membrane elements were investigated. A reverse osmosis system was designed and simulated using available software (e.g., ROSA and IMSDesign). The characteristics of the most promising membranes were identified for operation at Matruh (Mediterranean Sea) and Sharm El‐Sheikh (Red Sea). The present work shows that the lowest cost of seawater desalination is obtained with membranes having high salt rejection, high permeate flow, high membrane active area, and permeate flux greater than 0.914 m3/(d·m2). Moreover, the cost of seawater desalination in summer is lower than in winter by 5% for Matruh and 2.7% for Sharm El‐Sheikh. However, the impact of water salinity on the cost and specific energy consumption is higher than that of the seawater temperature. The cost of Mediterranean seawater desalination is lower than that of the Red Sea by 10.6%. Cost analysis at five different locations in Egypt shows that the highest cost takes place at Suez (Gulf of Suez), and the lowest cost occurs at Matruh (Mediterranean Sea). Practitioner Points Twelve different membranes were investigated for use under typical hot climate conditions. The cost of seawater reverse osmosis (RO) desalination is lower in summer by 2.7%–5% compared with winter. RO desalination costs up to 10.6% less for the Mediterranean Sea compared with the Red Sea. The optimum membrane element performance characteristics were identified for use under hot climate conditions.

“…The oldest of these models are analyzed in the contribution by Soltanieh [Soltanieh and Gill (1981)]. More recent models describing the different local transport phenomena within the membranes with an increasing complexity can be found in Wijmans and Baker (1995), Gauwbergen and Baeyens (1998), Weissbrodt et al (2001), Moresi et al (2002), Kahdim et al (2003), Mehdizadeh et al (2005), Mane et al (2009), Malaeb and Ayoub (2011). Below, we shall nevertheless use a minimal model, since it is essential to investigate the associated limitations.…”

“…A wealth of literature was published in modeling RO membranes but most of it was in studying the performance of a single RO element [10][11][12]. Many studies investigated the performance of RO system without investigating the performance of each element *Address corresponding to this author at the School of Engineering University of the West of Scotland Paisley PA1 2BE, UK; Tel: +971507356657; E-mail: alialtaee@hotmail.com in the high pressure vessel [13,14]. As explained in the part-one of this study, the performance of RO system has to be evaluated to estimate the number and type of RO elements required for any new RO desalination plant.…”

A computational model for estimating RO system performance was developed in this study. Wide range of seawater concentrations 32000 mg/L, 35000 mg/L, 38000 mg/L, and 43000 mg/L were used as feed solution. Two different types of Filmtec RO membranes were investigated; SW30HRLE-440i and SW30HR-380. A pressure vessel of four RO elements was simulated in this paper. The recovery rate, ions rejection rate, flow arte, and permeate concentration was simulated for each element in the pressure vessel. The results from this study were compared with Reverse Osmosis System Analysis (ROSA) software assuming that the simulation results from ROSA are reasonably accurate. It was found that the results from this study were in a good agreement with ROSA. The model was also validated against a commercial RO system for seawater desalination, feed concentration 43000 mg/L. An agreement more than 85% was achieved between the model and the experimental data.
