Seawater Desalination

Seawater covers 71% of the planet surface and represents 97% of the world's water，and seawater has a lot of resources to be explored.Along with recycled wastewater, it is one of the few rainfall-independent water sources.However,in the current condition,seawater cannot be used directly because of the high salinity.To solve it,many methods of desalination are adopted. Desalination is a process ...

Prospects of nuclear desalination in Morocco

In the last few years, Morocco has faced a continuous series of dry seasons, which has put a great stress on its limited water resources. Hence, for some time now Morocco has been considering desalinating seawater to supply fresh water to some areas. In the early 1980's, due to limited energy resources, Morocco was obliged to consider other alternatives to meet its energy demands. A feasibility ...

An overview on nuclear desalination

One of the peaceful uses of nuclear energy is in freshwater production. The present work focuses on the recent world water situation, large-scale desalination processes, electricity production, and the features required by advanced inherent and passive safe reactors. The relevant economical assessment of these adapted reactors for water-electricity cogeneration have been carried out and compared ...

Seawater desalination — a green technology?

The need for resource-saving, low-impact “green” desalination technologies is evident as the use of desalination accelerates in many parts of the world. The concept of “best available techniques” (BAT) aims at the identification of state of the art technologies, processes, or methods of operation which indicate the practical suitability for preventing or reducing pollution of the atmosphere, ...

Advances in desalination technology

Seawater desalination has been the cornerstone of the Middle East's water supply strategy since the mid-1950s, and most of the installed desalination capacity is still provided by multistage flash evaporators. But, desalination is changing. In fact, the term "desalination" is no longer limited to seawater applications; desalination technologies are now routinely employed to desalinate brackish ...

Status and prospects of nuclear desalination

Recent statistics show that currently 2.3 billion people live in water-stressed areas and among them 1.7 billion live in water-scarce areas. In the light of this, the Millennium Declaration by the UN General Assembly in 2000 has set up a target to halve, by the year 2015, the world population who are unable to reach, or to afford, safe drinking water. Better water conservation, water management, ...
