“…According to Hamdan, 2021 [66], RODP plants offer a possible decentralized solution to provide citizens with safe, fresh water, generated from brackish and seawater aquifers, considering energy sustenance through a PV (Table 3). The incorporation of small-scale PV systems into the RODPs is seen as a promising technology [68]. Small-scale, direct-coupled, variable-speed PV-RO systems are technically viable, according to Jones (2016), but the flow rates, pressures, and membrane recovery rates must be regulated, to prevent the membrane degradation or fouling.…”

The natural potential of Chile—solar energy and 8 km of coastline—make the implementation of small-scale reverse osmosis desalination plants (RODPs) in coastal areas energetically supported with photovoltaic systems (PVs) feasible. This work considers a survey of the plants in Chile. As a demonstration of a RODP, a technical/economic evaluation is carried out, analyzing four possible cases in which different energy configurations are proposed: electric grid, diesel generator, and photovoltaic systems, without or with batteries. Finally, the challenges and opportunities of these plants are presented. The results obtained indicate that there are 39 plants in operation, which produce an average permeate water flow of Qp 1715 m3d−1. Solar Explorer, and Homer Pro software are used for a plant that generates 8 m3day−1 of permeate water, resulting in the conclusion that Case 3 is the most economically viable, as it has a useful life of 20 years and will have an annual solar contribution of more than 65%. The levelized cost of water production is 0.56 USDm−3 (RODP/PV) and 0.02 USDkW−1h−1 was obtained for the LCOE. Finally, this case contributes to the mitigation of climate change.

“…The scarcity of fresh water resources has become a serious challenge to the sustainable development of countries in the world. At present, there are many freshwater access technologies, such as multi‐effect distillation, [1] ultrafiltration, [2] microfiltration, [3] reverse osmosis [4] and so on, which are used for seawater desalination. However, these technologies cannot be applied on a large scale due to their high cost and complex process.…”

Solar steam generation (SSG) has become a cutting-edge technology to solve fresh water shortage. Herein, a neotype photothermal conversion material (CAEP-PFO) was designed and prepared by using expanded perlite as raw material and sodium alginate as crosslinking agent, through directional freezing, surface carbonization and oil-phobic modification. Through characterization analysis, the results showed that the prepared CAEP-PFO has a porosity of 92 %, a light absorption of more than 88 %, and a low thermal conductivity of 0.06834 W m À 1 K À 1 . In addition, CAEP-PFO exhibits excellent salt resistance and oil repellency, and possess an evaporation efficiency of 78.6 % in 10 % brine and 80.2 % in oil-bearing wastewater under the irradiation of 1 kW m À 2 , respectively. After 8 cycles of test, the evaporation efficiency in pure water is relatively stable, and the average evaporation efficiency can reach 84.28 %. The research may lay a foundation for the future preparation of photothermal materials and the practical application in seawater and oil-bearing wastewater.
