“…Development and implementation of such technologies are of particular importance to remote arid areas of developing countries where people suffer the most from the lack of access to safe potable water. In Malek et al [103], the direct coupling of wind energy with membranes was proposed as a solution to reduce the system costs as well as technical drawbacks associated with using intermediate energy storage systems such as acid-lead batteries, supercapacitors and flywheels.…”

“…The direct connection of the wind turbine to a batch recirculating ED system (see Figure 5) was studied by Malek et al [103] in a novel attempt in terms of coupling a wind turbine to a varying resistance load; since in all previous applications, wind turbines were mainly used to power constant resistance loads, these being either electricity grids or in smaller scales battery banks and supercapacitors [55,98,99,104]. 6 shows the results obtained from systematic investigations of the wind-ED system performance under various wind speed conditions (from 2 to 10 m/s) with the aim of determining the impacts of low and high wind speeds on the desalination performance of ED by measuring clean water production and specific energy consumption (SEC) under constant wind speed conditions.…”

“…The results suggest that the desalination performance of the wind-ED system is mainly influenced by the wind speed when operating in the first power region, where no constraints have yet been posed on the voltage increase and, thus, the current transfer across the membranes varies primarily as a result of the wind speed. However, the dependency of the desalination performance on the wind speed diminishes significantly once the torque control system on the frequency inverter is activated to limit the voltage increase, as a result of which the power and correspondingly the desalination performance of the wind-membrane system begin to be principally controlled by the R stack variations [103]. .…”

Supply of potable water requires energy and unfortunately most of the countries with minimal access to safe drinking water are also poor in terms of access to reliable energy grids. However, many of such regions have access to other sources of water (such as brackish and groundwater) that can be treated for producing drinking water if correct treatment systems are put in place. Moreover, many of the electrically remote areas are rich in terms of renewable energy (RE) resources (such as wind and solar) which can be potentially employed as the main source of energy for powering water purification systems. Therefore, development and implementation of off-grid RE powered contaminant removal systems, for producing freshwater from available resources (such as brackish and groundwater), can be considered as an effective and potentially sustainable solution for overcoming the drinking water scarcity issue in remote regions of developing countries. This chapter revises the state of the art related to desalination systems using electrodialysis technology powered by wind energy for decentralised water production.

“…ED and EDR are a well-established process and are commercially available since the late 1950s [30] and since 1974 [31], respectively. It has already been applied for saline water treatment, brackish water treatment, and wastewater treatment [32,33]. The size of the modules is customized via a modular principle of the arrangement of cell pairs (100 to 600 pairs per electrodialysis stack in industrial scale) [30,34].…”

Electrochemical technologies for the treatment of industrial and municipal wastewaters, potable water, and groundwater, are presented, focusing on the main water constituents: inorganics, organics, micropollutants, and microorganisms. Removal of inorganic compounds by electrodialysis, electrocoagulation, and capacitive deionization as well as removal of organics and micropollutants by electrosorption, advanced oxidation processes, and anodic oxidation with boron‐doped diamond electrodes are reviewed. Electricity can be generated by degradation of organic compounds in microbial fuel cells and dehalogenation by cathodic reduction minimizes toxic substances in water. The disinfection of different types of water is also presented and it is shown that electrochemical methods offer versatile approaches to contribute to an sustainable future water management.

Energy is the main concern in the design and implementation of desalination plants; this concern is even more significant in remote areas with limited or no access to the main power grid. This paper presents an off‐grid hybrid renewable energy assessment for a reverse osmosis desalination plant. The plant with a 10 m3 desalination capacity is located in al‐Batinah region in the north of Oman. For better assessment, the meteoritic data of the site such as temperature, wind velocity, solar radiation, and clearness index are extracted. The simulation has been done using Homer software, and all possible combinations of photovoltaic panel/wind turbine/generator/battery are calculated and compared with one another. At last, two different approaches, a complete renewable hybrid energy with and without generator backup, are compared and the results are provided. The results of the experiment show that the most economic off‐grid hybrid energy system is a combination of a 12.5 kW PV panel with 335 W energy production for each panel, a battery bank consisting of 12 batteries with 205 Ah capacity, and a generator as a backup. The cost of energy for one kWhr is $0.28; on the other hand, a hybrid renewable energy system with the combination of PV/wind turbine/battery costs $0.37 per kWhr.
