“…By adding permeate water cooling unit in the summer, the maximum production rate will be increased from 2.78 L/m 2 h in Case I to 3.81 L/m 2 h in Case II, as well as the overall efficiency of the system will be improved from 46.6% in Case I to 61.8% in Case II. Elzahaby et al (2016) studied a direct contact membrane distillation system assisted by a cooling water tank and solar energy shown in Fig. 3.…”

Freshwater and energy are critical components for the growth and progress of societies. The scarcity of freshwater and rapid population growth, especially in remote countries, has led to an urgent need to develop desalination technologies in order to raise its productivity and reduce its energy consumption rates. Membrane distillation is one of the effective methods characterized by its high productivity, but its disadvantage by higher electricity consumption. Also, solar stills are one of the sustainable and economical technologies, but the disadvantage by lower productivity. Accordingly, this manuscript dealt with a comprehensive review and detailed comparison of the most important modifications and innovations that were made to the design of the membrane distillation units, which aim to reduce electricity consumption rates, as well as the design of solar stills, which aims to maximize the productivity and efficiency. This was done by providing a detailed comparison of the most important three axes of modifications and innovations that were addressed by recent previous studies on the design of membrane distillation units and solar stills, and their statement as follows: preheating technology, use of the thermal storage materials, and nanomaterials technology. Finally, based on this review, the authors make some recommendations for future work in the field of solar and membrane desalination.

“…High water fluxes can be achieved if heat losses are minimized [53,96]; (ii) the effect of various geometric and operating frameworks (including system temperature, water flow rate, salt absorption rate, cooling temperature and the diameter of the system layer) on the system performance. The study showed that productivity as well as the efficiency of the system can be achieved through optimization of these operating conditions [53,97].…”

Fresh water resources are depleting rapidly as the water demand around the world continues to increase. Fresh water resources are also not equally distributed geographically worldwide. The best way to tackle this situation is to use solar energy for desalination to not only cater for the water needs of humanity, but also to offset some detrimental environmental effects of desalination. A comprehensive review of the latest literature on various desalination technologies utilizing solar energy is presented here. This paper also highlights the environmental impacts of desalination technologies along with an economic analysis and cost comparison of conventional desalination methods with different solar energy based technologies. This review is part of an investigation into integration of solar thermal desalination into existing grid infrastructure in the Australian context.

“…The values of each parameter in the decomposition table indicates areas where a certain stills can be improved to make it competitive and to reach the efficiency frontier. This integrated fuzzy AHP DEA approach can be used in other desalination system to find the relative efficiency of desalination processes like multi-effect flash distillation (Baig et al, 2011;Choi, 2016;Elzahaby et al, 2016), membrane distillation Zhang et al, 2015), FO & RO(forward and reverse osmosis) (Altaee and Hilal, 2015;Delgado-Torres and García-Rodríguez, 2010;, ion exchange (AlMarzooqi et al, 2014;, seawater greenhouse techniques (Davies et al, 2004Davies and Paton, 2005;, etc. by selecting the techno-economic input/output parameters.…”

Desalination using solar stills is an ancient economic method for water desalination. Over the years, research and development in the area of solar still has resulted in increased distillate yield by means of integration of PCM (phase change material), photo-voltaic thermal (PVT), etc with the still. Nano-PCM is an upcoming technology which modifies the thermal performance of PCM. The aim of this research is to analyze the efficiency of 20 solar stills including nano-PCM based solar stills considering various input and output criteria using integrated fuzzy analytical hierarchy process (AHP) and data envelopment analysis (DEA). The efficiency derived here is relative with regard to the parameters and stills considered in this study. The result infers that, even though the productivity of stepped solar still with sun tracking system was high, but when techno-economic aspects were considered it is not among the top solar stills. The analysis indicated pyramid type solar still, single slope solar still with PVT, solar still with NPCM (paraffin + copper oxide), solar still with NPCM (paraffin + titanium dioxide) and solar still with PCM (paraffin) occupies the top five positions with relative efficiency of 100, 100, 88.47, 88.46 and 76.93% respectively.
