“…Seawater is one of the most easily accessible water sources to achieve the goal of freshwater production [14]. With current desalination methods, seawater can, under various circumstances, become a solution to freshwater scarcity, emerging as one of the most effective options to alleviate water stress [15] in regions with low precipitation rates [16], prolonged drought effects [17], aquifers contaminated with heavy metals [18] due to agricultural or livestock activities [19,20], uncontrolled mining activities [21], or unregulated discharge of sewage or industrial wastewater [22,23]. For all these reasons, this technology is indispensable in many areas of the planet.…”

The analysis of energy consumption in reverse osmosis desalination plants is the most important and relevant factor to study, because this parameter indicates the level of efficiency and competitiveness of the plant. The direct consequence of the high specific energy consumption (SEC) of a desalination plant in the production of water is one of the main obstacles to the exponential expansion of this technology worldwide. The methodological procedure used to carry out the work is based on the analysis of energy consumption, maintenance costs, staff, membranes, and reagents of three desalination plants with a production of more than 23,000 m3/day located in the Canary Islands (Spain); all data are obtained from real analyses collected “in situ” from 2015 to 2018. One of the main objectives of the current research on desalination plants is to reduce the SEC of seawater desalination plants (SWRO), incorporating energy recovery systems (ERS) and high efficiency pumps (HEP), and to implement different operational configurations with the aim of minimizing the energy requirements necessary to obtain a good product quality at minimum production cost.
