“…Certainly, the conductivity boost will considerably affect the membrane production in short and long terms [14,27,29,31,[40][41][42][43]. In short term, the permeate quality as well as productive capacity will diminish progressively.…”

“…The feed water temperature changes will affect the RO performances [14,27,29,[40][41][42][43]. According to the industrial desalination practice, an increment of 4°C of the feed temperature will generate a membrane production augmentation at around 10%, which is a standard fact [31,44].…”

“…Indeed, the pressure of the 1stand 2ndstage passed to 12.8 and 10.5 bars, respectively. The pressure increase was due to the feed temperature decline that changed the structure and physical characteristics of the polymeric membrane such as the pore size [14,29]. Also the augmentation of the feed temperature diminished water viscosity [14,41] and therefore affected the pressure.…”

“…As a consequence, in these operating conditions, a raw water temperature decline of 6°C generated an increase of the feed pressure of about 1.7 bars in the 1st stage and 1.3 bars in the 2nd stage. Figure 6 displays the impact of the feed temperature [29] seasonal variation on membrane permeability of the 1st and 2nd stages.…”

“…Water desalination applying the RO technique includes several parameters that need a deep investigation to understand the relationship between operation and design parameters [29]. To understand deeply the operation of RO plant, it is crucial to collect the correct and significant data, to interpret the gathered data using the required analytical methods, and to carry out operations of maintenance in order to ensure the correct operation of the RO and pretreatment systems as designed [30].…”

Reverse osmosis (RO) plays an outstanding role in water desalination worldwide. Performance of this technique depends on membrane fouling and the raw water seasonal variations, especially temperature and raw water salt concentration. Hence, to neutralize the impact of temperature and feed concentration on the performance parameters, the data collected from the brackish surface water plant were standardized through the use of the American Society for Testing and Materials methods. The value of this normalization is to be able to discern the performance variation which is due to the membrane aging and the membrane fouling, scaling or degradation. The present research investigates the real industrial results gathered from the first experience of brackish surface water demineralization by RO in Morocco. The results obtained evidently show that the feed water is subject to serious seasonal variations in terms of feed temperature and feed salts concentration, which noticeably affect the feed pressure, membrane permeability, and permeate conductivity. The standardized permeate flow, standardized pressure drop, and standardized salt passage show that the performance of the plant was steady all over the period of the monitoring and the observed performance decline-was due to membrane fouling.

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.
