Sustainable desalination: environmental approaches
Abstract The environmental issues of possible concern during construction and operation of desalination plants (mainly large-scale facilities) include impacts that are common to many coastal development projects (e.g. land use and aesthetic impacts), as well as specific impacts associated with the elements of the desalination system and auxiliary infrastructure. In the latter category these ...

British Virgin island dependent on reliable freshwater for GDP growth
Tortola is the largest British Virgin island in the Lesser Antilles with an approximate population of 24,000 residents. 92% of its Gross Domestic Product (GDP) comes from tourism where close to one million people visit the island every year. As with many island nations without natural aquifers, Tortola must produce all of its drinking water and demand is constantly high. Historically the island ...

Design challenges and operational experience of a mega med Seawater Desalination Plant in Tianjin
Abstract This article is a continuation of the article "Sliding Pressure Turbine Integrated with Seawater Desalination Facility (MED)" [1] presented at the IDA 2011 World Congress. The previous article described a unique MED-TVC plant design that is able to integrate with a sliding pressure turbine to supply motive steam to a thermal desalination process. This turbine is part of the Tianjin ...

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 ...

Chilean mine utilises new desalination plant
After an investment of $100 million (£63.7 million), Chile is now the proud owner of the Mantoverde desalination plant – the first of its kind in the country. The desalination plant works by sourcing seawater in its catchment tower 300m from the seashore. It then begins a process to filter and purify the water, removing impurities such as salt and excess residue so that the water can ...

Rapid sand filtration pretreatment for SWRO: microbial maturation dynamics and filtration efficiency of organic matter..Desalination 286 :120, 2012
Rapid sand filtration (RSF) is used today as an effective pretreatment procedure to enhance water quality prior to reverse osmosis (RO) membranes in desalination plants. RSF in newly operated desalination facilities requires a maturation period of about three months before the feedwater may be filtered efficiently. To date the desalination industry RSF has regarded RSF mainly as a physical ...

Report: California’s Reliance on brackish water desalination to increase
Years of drought in California may result in the state becoming more reliant on brackish water desalination, according to the Pacific Institute. In “The Cost of Alternative Water Supply and Efficiency Options in California,” the Oakland-based nonprofit research institute looks at the costs of potential water supply sources and other economic factors. The institute states: The study ...

Desalination: Looking to the future
Untitled Document Even though the volume of the earth's water is vast, less than 10 million of the 1 400 million cubic metres of water on the planet is of low salinity and suitable for use after applying conventional water treatment alone. The other 97.5% of the water on our planet is to be found in the oceans, where it is officially classified as seawater. Desalination ...

Algae Bloom Detection for Desalination Plants
Despite the fact that water covers 70 percent of the planet, a mere 3 percent of that water is fresh. Most of the planet’s freshwater is not readily available. The water systems that perpetuate ecosystems are stressed by a growing human population, disappearing wetlands, agricultural consumption and droughts related to climate change. At present, 14 of the world’s 20 largest cities ...

Seawater desalination for methanex
Methanex has a large methanol production facility in Punta Arenas, Chile. In this region of the world, fresh water is not available, and the facility requires seawater desalination to provide drinking water and process water. When the facility underwent renovation and expansion of their facilities, Aqua-Chem ICD provided a total of five (5) new Once through Multi-stage Flash plants. The Problem ...

Plans are underway to build the largest desalination plant, South Africa - Case Study
Plans are underway to build the largest desalination plant on the African Continent. The emergency decree allows the government to fast track approval of the plant. The city had resorted to increasingly drastic measures to clamp down on water usage, including "naming and shaming" the 100 addresses using the most water and fining residents who failed to comply with the 50 liter (13 gallon) limit ...

Toxic brine from desalination plants
A new study has highlighted the problem of brine discharged from desalination plants. More than half the brine comes from Saudi Arabia, the United Arab Emirates, Kuwait and Qatar, with Saudi Arabia alone accounting for 22%. 3 countries - the Maldives, Malta and the Bahamas - meet all their water needs with desalination. Not surprising when you see the islands from the air: The number of ...

Israel Once Again Faces Prolonged Drought
The Sea of Galilee, from which Israel draws part of its water supply, has receded to record levels. Desalination and water conservation may not be enough to overcome it Israel is known as the worldwide leader in desalination technology, with desalination accounting for 40% of the nation’s potable water. But it may not be as widely known that Israel also leads the world in water reuse, ...

Graphene Sieve Material Promising as Desalination Membrane
A new graphene-based material with a sievelike structure may prove to be an efficient, affordable material for desalination membranes. Scientists from the University of Manchester’s National Graphene Institute developed the graphene oxide, according to the BBC. The material could help make small-scale desalination affordable, which may help those without access to clean drinking water. ...

The role of nuclear desalination in the Kingdom of Saudi Arabia
In this study, the role of nuclear desalination in Saudi Arabia is investigated. A water demand forecast between the years 2000 and 2025 was established for the Eastern region of Saudi Arabia as part of the collected input data for the DEEP computer code. The DEEP computer code was run for several options of energy sources such as PWR (600 MWe), SPWR (160 MWth), PHWR (450 MWe), HR (200 MWth) and ...
