Desalination and renewable energy, part I: Context: water and energy

1.1

Context: Water and energy The problem of fresh water lacking in many areas all over the world and its solution: desalination People have to face with the problem of fresh water lacking in many regions of the world. In 2005, half a billion people lived in the condition of water–scarce and water–stressed . Many of them have to drink contaminated water which is not good to the health. Population growth and the pollution of natural sources of freshwater cause a significant and on-going reduction of clean drinking water. Increasing water demands for agriculture, industry and tourism let the world have to find solutions to this problem. In some areas such as the coastal regions or islands, the desalination techniques were applied to convert seawater or brackish water into freshwater which is useful for drinking, cooking … Fig 1.1. Charts showing portions of total desalination capacity and total number of desalination plant installations worldwide by source water USA and especially … [Read more...]

Optimal management of water pumping and desalination process supplied with intermittent renewable sources

World natural resources of fresh water are constant or even decreasing while the world population continues to grow rapidly and is expected to increase from a current value of 6 billion inhabitants to 9 billion over 2050. This growth is associated with rapid expansion of urban regions, which consume large amounts of fresh water. Population increase and associated changes in lifestyle stress limited water resources even further. Governments and municipalities struggle to secure sufficient fresh water resources for the ever-increasing demand by adopting strict policies for conservation, water reuse, imports, transportation, and desalination. According to the International Water Management Institute (IWMI), one over three peoples globally faces some form of water scarcity; one-fourth of the world population lives in areas where water is physically scarce, and over one billion people live where water is econom`ically scarce, or places where ‘‘water is available in rivers and aquifers, but … [Read more...]
