“…The same goes for other metals of increasing commercial importance, such as lithium [17]. The status and prospects of hybrid processes using brine, thermal waste, and water from wastewater purification are described in detail in several recent publications [18][19][20][21][22]. These processes aim to increase the productivity and energy efficiency of desalination, reducing the environmental impact.…”

All the urban areas of developed countries have hydric distribution grids and sewage systems for collecting municipal wastewater to treatment plants. In this way, the municipal wastewater is purified from human excreta and other minor contaminants while producing excess sludges and purified water. In arid and semi-arid areas of the world, the purified water can be used, before discharging, to enhance the energy efficiency of seawater desalination and solve the problems of marine pollution created by desalination plants. Over the past half-century, seawater desalination has gradually met demand in urbanized, oil-rich, arid areas. At the same time, technological evolution has made it possible to significantly increase the energy efficiency of the plants and reduce the unit cost of the produced water. However, for some years, these trends have flattened out. The purified water passes through the hybridized desalination plant and produces renewable osmotic energy before the final discharge in the sea to restart the descent behaviour. Current technological development of reverse osmosis (RO), pressure retarded osmosis (PRO) and very efficient energy recovery devices (ERDs) allows this. Furthermore, it is reasonable to predict that, in the short-medium term, a new generation of membranes specifically designed for improving the performance of the pressure retarded osmosis will be available. In such circumstances, the presently estimated 13-20% decrease of the specific energy consumption will improve up to more than 30%. With the hybrid plant, the salinity of the final discharged brine is like that of seawater, while the adverse effect of GHG emission will be significantly mitigated.

Due to disparities in the allocation of rainwater and drought, extreme exploitation of groundwater reservoirs has depleted water supplies in many locations. In addition, improper disposal of domestic and industrial waste leads to poor drainage and deterioration of water quality. According to studies, desalination methods are an effective solution for treating sea and brackish water and making it usable in daily life. Solarpowered desalination has recently received a great deal of attention around the world. Previously, most experimental studies focused on the use of solar energy in traditional desalination methods such as multistage ash and multi-effect distillation. Desalination with reverse osmosis has become popular due membrane technology improvement and bene ts like high recovery ratios and low energy consumption. This article aims to comparatively and systematically review the economic feasibility of the use of solar photovoltaic reverse osmosis in desalination in Morocco and the Middle East and North Africa (MENA) region. HighlightsThe Middle East and North African (MENA) countries are advantageously located in the sunbelt region.Desalination is the solution to the scarcity of freashwater in the mostly arid MENA region.Increasing energy prices and climate change concerns imply a need for a sustainable and green solution.Solar-powered desalination technology is both cost-effective and environmentally friendly. Solar-powered reverse osmosis is more economically feasible and less polluting than other rechnologies. 2008Energy Policy
