“…Coupled with global environmental crises, the development of sustainable manufacturing processes has become a major goal for industries. In this regard, combining electrochemical processes with renewable energy sources (e.g., solar panels) can reduce energy consumption and carbon intensity . Recently, electrochemical methods for water purification have been hybridized with dye-sensitized solar cells for direct conversion of light to electricity. , The photoanode uses desalinated chloride to generate reactive chlorine species, which can treat wastewater, while the cathode produces molecular hydrogen .…”

Agricultural development, extensive industrialization, and rapid growth of the global population have inadvertently been accompanied by environmental pollution. Water pollution is exacerbated by the decreasing ability of traditional treatment methods to comply with tightening environmental standards. This review provides a comprehensive description of the principles and applications of electrochemical methods for water purification, ion separations, and energy conversion. Electrochemical methods have attractive features such as compact size, chemical selectivity, broad applicability, and reduced generation of secondary waste. Perhaps the greatest advantage of electrochemical methods, however, is that they remove contaminants directly from the water, while other technologies extract the water from the contaminants, which enables efficient removal of trace pollutants. The review begins with an overview of conventional electrochemical methods, which drive chemical or physical transformations via Faradaic reactions at electrodes, and proceeds to a detailed examination of the two primary mechanisms by which contaminants are separated in nondestructive electrochemical processes, namely electrokinetics and electrosorption. In these sections, special attention is given to emerging methods, such as shock electrodialysis and Faradaic electrosorption. Given the importance of generating clean, renewable energy, which may sometimes be combined with water purification, the review also discusses inverse methods of electrochemical energy conversion based on reverse electrosorption, electrowetting, and electrokinetic phenomena. The review concludes with a discussion of technology comparisons, remaining challenges, and potential innovations for the field such as process intensification and technoeconomic optimization.

“…Using the data provided by Ali et al [45] and "EES: Seawater External Library," the DCMDC crystallization subsystem is studied. In addition, the CAS subsystem is studied using "EES: Nasa External Library" and the information provided by Mir et al [37]. The thermodynamic properties of the sulfate (SO 4 ) are obtained using the HSC Chemistry software [46] because there is no library for SO 4 properties inside EES.…”

“…A DCMDC crystallization system is used as a saltwater desalination and ions recovery system. In addition, a chlor-alkali system (CAS) is used to manage the rejected brine from the crystalized, where the chloralkali system can produce hydrogen (H 2 ), chlorine (Cl 2 ), and sodium hydroxide (NaOH) according to [37], where the Cl 2 is used for water treatment, PVC production, and wind turbine blades production according to [38]. The NaOH is stored for industrial use, such as producing soap, rayon, and paper, according to [39].…”

Sustaining agricultural demands is a typical problem, particularly in locations afflicted by the scarcity of fresh water, poor farming soil, and hot weather. The main goal of this study is to perform a thermodynamic analysis of an integrated multigeneration system containing a direct contact membrane distillation crystallization system that recovers beneficial hydroponic farming nutrients from seawater using renewable energy resources. A parametric study is carried out to determine the impacts of various factors on the system, such as changing the rate of mass flow rate, recovery ratio, and salinity. This study proposes a novel sustainable multigeneration system for seawater desalination and ions recovery using the direct contact membrane distillation crystallization system to provide the hydroponic solution and greenhouse ventilation using the dual evaporator vapor compression refrigeration system. With overall exergy efficiency and energy efficiency of 41.40%, and 39.80%, respectively, the system requires about 1182.69 kW and 5314.6 kW of electrical and thermal power in total, respectively, to desalinate 5 kg/s of seawater and recover 170 mg/s of Sulfate (SO4), 81.28 mg/s of Magnesium (Mg), 25.48 mg/s of Calcium (Ca), and 24.16 mg/s of Potassium (K), yielding about 4.4 kg/s of a hydroponic solution, and ventilating 25 greenhouses with a volume of 600 m3 of single greenhouse.

In hot‐arid climatic regions like Qatar, it is important to facilitate pedestrians' journeys. One way to do so is by providing them with shelters, that is, from a station to their destination building. It is necessary for such shelters to provide on‐site space cooling and freshwater in an off‐grid condition. In this respect, the proposed off‐grid system in this study includes bifacial photovoltaic (BPV) and a solar thermal collector for energy generation with battery and thermal storage units. BPV with an efficiency of 16% can produce power up to about 6.1 kW on the rooftop, which also reduces the cooling load via effective shading. The ejector‐based cooling system is deployed for efficient space cooling in high ambient temperatures (more than 28°C), while for less than 28°C, both fan and water misting systems are operated for the comfort of pedestrians. Finally, an electrodialysis system is integrated to generate freshwater from seawater to be used for drinking and water misting purposes in the off‐grid sustainable shelter. The overall energy and exergy efficiencies of the system are calculated to be 13.2% and 5.29%, respectively. The effects of several parameters are also studied to observe the overall system efficiency and the energy generated and consumed by the system.
