A global overview on nuclear desalination
Nuclear desalination is considered one of the viable sources of producing the fresh water needed in arid areas. Nowadays, several countries have shown interest in the use of nuclear energy for seawater desalination, because recent studies have demonstrated that nuclear desalination is not only feasible but also economical, and this has already been demonstrated in several countries. Although the ...

R&D areas for next-generation desalination and water purification technologies
By 2020, desalination and water purification technologies are expected to contribute significantly to ensure a safe, sustainable, affordable and adequate water supply in India. The cost of producing water from the current-generation desalination technologies has declined over time at a rate of only approximately 4% per year. Hence the need to accelerate our Research and Development (R&D) ...

A joint power and desalination plant for Sinai and the Gaza Strip
Desalination can be a cost-effective way to produce fresh water and possibly electricity. The Gaza Strip has had a complex hydro-political situation for many years. Gaza is bordered by the Mediterranean sea in the west, by Israel to the north and east and by Egypt in the south. Water and electricity consumption in the Gaza Strip is expected to increase in the future due to the increasing ...

Study of fouling in two-stage reverse osmosis desalination unit operating without an inlet pH adjustment: diagnosis and implications
In the current work, the diagnosis of a reverse osmosis desalination unit is reported. Over the two last decades, the studied desalination unit was supplying a 1,200 bed hotel. The feed water was driven from a well near the sea. The desalination unit has two stages giving an average recovery equal to 81%. The behaviour of all water streams with respect to aggressiveness and scaling tendency ...

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 ...

Wastewater reclamation using discarded reverse osmosis membranes for reuse in irrigation in Djibouti, an arid country
The purpose of this paper is to establish the feasibility of recovering discarded reverse osmosis (RO) membranes in order to reduce the salinity of domestic treated wastewater. This study shows that the reuse of RO membranes is of particular interest for arid countries having naturally high mineralized water such as Djibouti. The pilot desalination unit reduces the electrical conductivity, the ...

Desalination and Agriculture: Lessons From Spain
Although desalination is commonly believed to be too expensive for agriculture, Spain is disproving the notion. Spain has made a success of desalination, even for agricultural irrigation, despite long-standing challenges that in some cases have made it too expensive for the application. As far back as 2012, approximately 22% of desalinated water in Spain was already used for agriculture. ...

Thermodynamic efficiencies and GHG emissions of alternative desalination processes
Three alternative approaches to desalinating seawater were evaluated with respect to their thermodynamic efficiencies and greenhouse-gas emissions. The technologies considered were multistage flash distillation (MSF), reverse osmosis (RO), and membrane distillation (MD). The analysis was based on published stream data from large-scale operational MSF and RO facilities and experimental-scale data ...

Optimisation of Osmosis. Jan Schallenberg, Kurita Europe GmbH, Germany, outlines the benefits of raw water pretreatment for reliable desalination by reverse osmosis - Case Study
Desalination by reverse osmosis (RO) is a fast growing technology, which is gaining more and more market share in the field of desalination applications. RO plants are able to produce extremely pure water with minimal impurities, even if they are charged with highly contaminated feed water. Based on the fact that the RO membranes themselves are able to separate the smallest ions out of the raw ...

Seawater desalination utilising waste heat by low-temperature evaporation
Utilisation of waste heat is one of the ecofriendly ways to produce low-cost desalted water. Keeping this in mind, Low-Temperature Evaporation (LTE) desalination technology utilising low-quality waste heat in the form of hot water (as low as 50?C) or low-pressure steam (0.13 bar) has been developed to produce high-purity water (conductivity Keywords: LTE desalination, low temperature evaporation, ...
