“…In a recent paper by Sayyaadi and Saffari [10], a multi-objective evolutionary algorithm was used to minimize the unit cost of product calculated by a thermoeconomic expression; the analysis identifies relevant margins for improvement by reduction of exergy destruction and product cost compared to a reference base case. Another interesting study by Manesh et al [11] proposes an exergoeconomic multi-objective optimization of a MED-RO desalination plant, identifying a Pareto optimal frontier for the two objective functions "Gained Output Ratio" and "cost of desalinated water production"; this paper also defines an optimal coupling of the system with a site utility steam network, following the principles of process integration [12]. As reported by Sharaf [13], the exergy and thermoeconomic analysis is performed for a combined solar organic cycle with MED desalination process, pointing out that direct coupling of solar collectors with MED process is more viable than an integrated solar-Organic Rankine Cycle-MED scheme and that the parallel feed configuration is preferable over the forward feed and the backward feed ones.…”

“…Among them, only about 3% of the capacity was provided to seawater desalination projects (1573,760 m 3 /d), indicating that RO membranes have been extensively used in many other water treatment projects. Moreover, combination of different desalination technologies has become a new trend for various water treatment scenarios [ 18 , 19 , 20 ]. For instance, in the project of coal chemical industrial wastewater treatment, RO was coupled with membrane bioreactor (MBR) and MED processes as an integrated system, providing a capacity of 20,000 m 3 /d.…”

In recent decades, the ever-growing demands for clean water in households and industries have urged researchers to take every possible step to deal with the global water crisis. Seawater desalination has turned out to be the most promising and efficient way to provide clean water. Owing to the advancement of synthetic chemistries and technologies, great success has been achieved in the desalination and utilization of seawater worldwide. China, with the world’s largest population, has pushed the development of desalination and multipurpose utilization of seawater further in respect of materials, technologies and services, etc. This review reports recent progress of desalination technologies accomplished in China, from the viewpoints of facilities and equipment, collaborations, technologies, applications, research abilities, services, and standard systems. Inspired by the Fourteenth Five-year Plan, it also proposes future perspectives of desalination in China.

“…They concluded that if the combined system applied, the water production cost decreases by about 8.8%. The combination of MED-RO desalination units with fossil fuel based utility steam network was investigated by Khoshgoftar-Manesh et al [5]. The total site analysis and an exergo-economic optimization were applied to find the optimal coupling of site utility and MED-RO desalination system.…”

Water and power cogeneration systems have been received more attention in recent years. In the present research, in addition to techno-economic investigation of the integration of multiple effect desalination/thermal vapor compression (MED/TVC) system and reverse osmosis (RO) system into the gas turbine (GT) power cycle, the GT/MED-TVC/RO configuration is also proposed. At first, the models used for GT, MED-TVC and RO systems are validated with the experimental data in the literature and good correspondence is found. In this study, the effect of air temperature on the GT stack outlet gases and the effect of seawater temperature on the MED-TVC GOR are investigated. Moreover, using the RO energy analysis, the most suitable RO membrane is selected by considering the permeate quality and membrane price. Then, the LCOE and LCOW for three scenarios of GT/ MED-TVC with 5000 m 3 /d, GT/RO with 5000 m 3 /d, and GT/MED-TVC/RO with MED-TVC and RO water production rates of 2000 m 3 /d and 3000 m 3 /d, respectively are determined. The results of the economic analysis in three scenarios showed that the least electricity cost and the least freshwater production cost belong to GT/MED-TVC and GT/RO configurations, respectively. Furthermore, the effect of number of stages of the MED-TVC system on the energy and economy of the GT/MED-TVC/ RO configuration is explored. It was observed that increasing the number of effects from 4 to 7 has no tangible effect on the LCOE. In addition, the output temperature and concentration of GT/MED-TVC/RO plant at different number of MED-TVC effects is determined. Finally, the effect of fuel cost and desalination system scale on the LCOW and LCOE at three configurations are investigated.
