State-of-the-art desalination still requires 7 to 30 kW-h of energy per 1000 gallons of desalinated water. The oceans and seas. “Desalination is our strategic choice to supply an adequate amount of drinking water to people across the Kingdom,” said Finance Minister Ibrahim Al-Assaf at the. Also, the higher pressures found in sea- water RO systems require use of mechanically stronger components. Clean water and reliable energy can be difficult to obtain in remote locations such as desert villages, secluded islands, and other places where no fresh water can be found. It will also help in reducing the financial load on MENA governments from power and water sectors, and thus diverting funds to much-needed educational, health and industrial sectors. Turning seawater into drinking and irrigation water can now be made with renewable energy in places where there is no community water infrastructure. The facility will employ the new solar saline water reverse osmosis (SWRO) desalination method using ultra-filtration (UF) for the pre-treatment process. Solar energy rates in Africa were researched heavily and it was discovered that most countries in Africa receive anywhere from 5000 to 8000 Wh/m2 of solar energy per day . It involves a broad range of technologies that yield access to marginal sources of water such as seawater, brackish ground- and surface water, and wastewater. Conventionally powered desalination is generally not a sustainable process, mainly because of the use of fossil fuel‐based power to supply the high energy needs of.

Using the sun instead of fossil fuels to power a desalination plant isn't a totally new idea. Increased fuel prices and concern over climate change are causing a push to shift to alternative sources of energy, such as solar energy, since solar radiation is abundant in this region all year round. It is clear that desalination plants requiring this quantity of energy input are not feasible in Texas colonias, which lack access to basic infrastructure, electricity, and running water. Keywords: Solar energy; Desalination; Solar stills 1.

Desalination systems using solar energy are quite common recently . The present work deals with a theoretical study of a water desalination system by solar energy using the humidification–dehumidifica-tion principle. Clean water and reliable energy can be difficult to obtain in remote locations such as desert villages, secluded islands, and other places where no fresh water can be found. selection of an appropriate desination technology, and shows where more research is needed in. INTRODUCTION Desalination of seawater is an energy intensive process.
