Coupling strategies for desalination plants with gas cooled reactors
Of late, high temperature gas cooled reactors have received significant attention due to many desirable operational and safety characteristics. Potable water has become more and more scarce due to the increasing population and environmental problems. Seawater desalination is an important consideration when searching for a supply of potable and industrial water. This study deals with possible ...

The potential for desalination in India
The demand for water in India is increasing rapidly owing to progressive increase in the use of water for irrigation, rapid industrialisation, population growth and improving life standards. A holistic approach is therefore required to cope with the freshwater needs of the country. It includes: seawater desalination in coastal areas; brackish water desalination; water purification; water reuse; ...

Implementation of build-operate-transfer schemes: obstacles & solutions
Abstract The past 15 years have shown increasing interest in large-scale desalination worldwide, where seawater desalination has been proven a reliable and feasible source of potable and industrial water, alleviating increasing consumer needs, pressures and demands. Many of the large-scale seawater desalination facilities built in the past years, or presently under construction, are delivered ...

Potential drawbacks associated with agricultural irrigation with treated wastewaters from desalinated water origin and possible remedies
Over 90% of the water supplied in the coastal region in Israel in 2013 (600 Mm3 y−1) will be from desalination plants. The wastewater generated from this water (>400 Mm3 y−1) is planned, after proper treatment, to be reused for agricultural irrigation, making this low-salinity water the main agricultural-sector future water source. In this respect both the Mg2 + concentration and the Sodium ...

A brief review of desalination in Australia in 2010
Recent climate changes and population growth throughout Australia have highlighted the need for more diverse and climate-independent water sources. Australia is the world's driest inhabited continent and the unpredictable climate means that the Australian population generally requires up to five times the water storage than does an equivalent population in the UK. Although 85% of its people live ...

Mechanical vapour compression desalination plant at Trombay
Desalination plants based on Mechanical Vapour Compression (MVC) technology are inherently the most thermodynamically efficient. The thermodynamic efficiency of the MVC process is derived from the application of the heat pump principle. A single unit of a two-effect MVC desalination pilot plant of 50 m?/day capacity has recently been commissioned at Trombay, Mumbai. The desalination unit is very ...

Desalination in Mining
With improvements in technology, desalination is becoming more viable both to provide source water and to treat process water Water access is a problem that must be overcome when starting or enlarging any mining project, and a lack of sufficient water in arid regions can be a deal-killer. Another water problem associated with mining (especially coal mining) is that wastewater is often too saline ...

Mild desalination of various raw water streams
For chemical industries, fresh water availability is a pre-requisite for sustainable operation. However, in many delta areas around the world, fresh water is scarce. Therefore, the E4Water project (www.e4water.eu) comprises a case study at the Dow site in Terneuzen, The Netherlands, which is designed to develop commercial applications for mild desalination of brackish raw water streams from ...

Nuclear desalination in the Arab world. Part I: relevant data
Middle Eastern and North African countries suffer from a shortage of fresh water resources. Statistical analysis shows that fresh water resources in these countries constitute less than 13% of the average world resources per capita. In the Arab world, the rapid increase in population and an increase in living standards led to a greater demand for fresh water and electricity. Accordingly, the Arab ...

Taking the pressure off desalination
California-based PAX Pure hopes to offer a new solution to water scarcity with its groundbreaking water purification tool. Developed by Jay Harman and Tom Gielda, PAX Pure technology desalinates and demineralizes water without membranes, moving parts or chemicals. Instead, the technology simply mimics high-altitude conditions. The big challenge with conventional desalination and demineralization ...

How is GWT's Seawater Reverse Osmosis Plant Different from Others?
A seawater reverse osmosis plant by definition utilizes the separation of salts and other mineral molecules from water. Freshwater supplies in some parts of the world are dwindling, hard to come by, or are heavily polluted. These are aspects of the growing epidemic of water scarcity.To reduce the strain on freshwater sources, we have to look elsewhere for water and there are no larger sources ...

Trends Shaping the Water Sector in 2023
Wastewater reuse and desalination may become more popular In 2023, drought, urbanization, and higher suburban populations will challenge the water sector as it struggles to meet demand. We predict that these challenges will drive interest in decentralization and nontraditional water sources, especially from wastewater reuse and desalination. Although funding gaps will remain, newer financing ...

Cal-Neva’s 2008 report on water treatment, desalination and filtration
This year proved to be one of expansion in all areas of the water industry. In the next few paragraphs I will attempt to report to all in this business what we found as we searched the world for new technologies. Let me explain what we do here at Cal-Neva Water Quality Research Institute of California. We scour the globe for emerging technologies that address either water treatment, ...
