  • Thermocline-driven desalination: the technology and its potential

    Seawater desalination technology is emerging as freshwater requirements are alarmingly increasing all over the world. Conventional technologies such as reverse osmosis and multistage flash evaporation have their limitations, such as chemical treatment and scaling. Low-Temperature Thermal Desalination (LTTD) is an attractive technology with vast potential. It makes use of the ocean temperature ...

  • Overview of seawater desalination status and challenges

    Introduction World oceans contain over 97.2% of the planet’s water resources. Because of the high salinity of ocean water and the significant costs associated with seawater desalination most of the global water supply has traditionally come from fresh water sources – groundwater aquifers, rivers and lakes. Today, however, changing climate patterns combined with population ...

  • 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; ...

  • Innovative seawater intake for reverse osmosis desalination plants

    Seawater desalination plants typically consist of four major unit operations: seawater intake, pretreatment, Reverse Osmosis (RO) stage, and posttreatment and brine discharge. The best way is to go through vertical beach wells, but the increase of the production capacity of the plants built in recent years makes open intake the only solution. These open ocean intakes draw seawater through the ...

  • Cost effective way to harvest estuarine water: variable salinity desalination concept

    Singapore, a small island city-state with some 700 km2 in land area and a population of 4.5 million, is always looking for innovative ways to find new water sources to meet its growing need for water. Rain falling in the urban fringe catchments is not harvested; these areas experience bouts of heavy rain but dry up during the dry season and, as such, the conventional approach of constructing ...

  • 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 ...

  • Is desalination the most sustainable alternative for water-shortage mitigation in Israel?

    Significant progress in seawater desalination technology has lowered its costs considerably, making it an attractive option to policy makers in countries facing water shortages. However, in making the decision to implement desalination, two issues are often ignored: firstly, seawater desalination is also associated with external costs. Secondly, alternative measures of managing water shortage may ...

  • 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 ...

  • Safety and reliability aspects of seawater reverse osmosis desalination plant of nuclear desalination demonstration project

    Desalination systems are mostly based on membrane (RO) and thermal (MSF and MED) processes. High-pressure operation and high level of corrosion are the major aspects of concern in a Seawater Reverse Osmosis (SWRO) Plant. Selection of the appropriate material for construction and the following of the proper design, fabrication and testing codes, and safe operational procedures ensure the safety of ...

  • Carlsbad project charts the future of sustainable desalination

    Over the past five years desalination is gaining momentum in California. With more than ten projects in various stages of planning, environmental review, design and construction, brackish and seawater desalination plants are planned to provide 400 MGD to 500 MGD of new drinking water supplies for the state by year 2015. One of the largest and most advanced projects under development today is the ...

  • 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 ...

  • Improvement in motor performance during high-pressure pump starting at NDDP, Kalpakkam

    The major energy requirement required for a seawater reverse osmosis plant is in the form of electrical energy. The primary energy requirement in the process is the electrical energy fed to high-pressure pumps to pressurise the feed seawater to the membranes. This high-pressure pump, being a high inertia load, requires very high torque at the time of starting. This requirement results in ...
