  • Desalination gets a graphene boost

    Original story at MIT News Jeffrey Grossman applies new materials research to making desalination cheaper and more efficient. With the intensifying drought in California, the state has accelerated the construction of desalination plants. Yet due to high construction and operating costs, as ...

  • A new approach to solar desalination for small- and medium-size use in remote areas

    A conventional solar still produces 6 litres of fresh water per square metre per day of collector surface. With heat recovery and air mass circulation we can reach up to 20 litres m3/d. The quality of the processed water is always very high so that the investment costs are justified. This depends on the material used and the price of the solar stills. The advantage of the solar still is ...

  • Selection and economical evaluation of solar desalination technologies via DesalSolar software

    Worldwide projection indicated that in 2020 the situation of water resources in Iran reach to scarcity. Besides, global warming and energy crisis have forced countries to use renewable energy resources. Solar desalination technologies particularly in remote area of Iran could be a method to emancipate from this crisis. In this paper, all kind of desalination technologies were reviewed. Then, ...

  • Technical and economic evaluation of an off-grid solar desalination system in Myanmar

    Myanmar is a unique country where the majority of the people live in rural areas, away from grid electricity and reliable water supplies. The penetration of grid electricity in rural areas is minimal and even then it is often erratic. This paper focuses on the challenges of transitioning from an electricity-poor country to a renewable energy based-economy augmented with photovoltaics (PV). ...

  • Low Temperature Thermal Desalination (LTTD): new sustainable desalination process

    Water is a scarce resource, and new collection and production facilities are predicted as necessary in the coming years. Sea water desalination shall be a key technology for the production of fresh water in many areas of the world, and great efforts are now in progress to increase the reliability of the desalination processes and to reduce the relevant investment and operation costs. In this ...

  • Water scarcity and solar desalination systems in the Eastern Mediterranean region: a case of Northern Cyprus

    Water is definitely physically scarce in the Middle East and North Africa (MENA) and the Mediterranean region with less than 1000 m3/capita/year. Water scarcity in these regions is a function of both water supply and water demand as both applies in most of the countries. Using the Falkenmark indicator the Mediterranean region will see increased deterioration in the availability of renewable ...

  • Desalination plant in Egypt runs on wind & sun

    Fortis Wind Energy (NL) and Juwi Renewable (DE) install a 100kW hybrid system in Egypt. Egypt, the land of the pyramids, is known to us for its ancient culture and the last year because of the uprisings for more democracy. Egypt is less known for its large population (83 million) lives along the Nile (only 5.5% of the surface). The rest of the country is desert. The River Nile runs into Egypt ...

  • Feasibility investigation of coupling a desalination prototype functioning by Aero-Evapo-Condensation with solar units

    The rural regions of south Mediterranean countries suffer from problems of drinking water supply. However, the majority of these regions have important resources of brackish salt water. Thus, brackish water desalination on a small scale presents a potential solution to this problem. For this reason, a number of small desalination prototypes are being developed worldwide. Bourouni et al. have ...

  • Water distillation by solar energy-a-review

    In this paper an attempt has been made to review in brief, work on solar distillation, its present status in the world today and its future perspective. This paper covers a large variety of systems used to convert saline water into fresh water suitable for human use. Finally, some general guidelines are discussed for selection of desalination systems and the parameters that need to be ...

  • Repowering and Modification of Grid Connected Reverse Osmosis Desalination Plants

    Currently, there is a strong demand for efficient seawater desalination plants, which can meet the tougher environment regulation and energy saving requirements. From this standpoint the present work was undertaken to include the proposed schemes for repowering and modification of Reverse Osmosis (RO) desalination plants. The model of Modified Desalination Plant (MDP) during sunny periods may be ...


  • Greenhouse based desalination for brackish water management using bittern evaporative cooling technique

    The Arab region is characterized by arid and semi-arid conditions with very limited renewable water resources. Most of the surface water comes from transboundary streams and most of the groundwater resources are fossil in nature. Water quality degradation and excessive use of pesticides and herbicides in agriculture pose severe environmental and health risks. The underlying research is a joint ...

  • What Are Solar Buildings Technologies?

    Solar buildings technologies use the non-polluting power of the sun to help heat, cool, and power our buildings. Because buildings now use one-third of the energy currently consumed in this country, the potential markets for using solar buildings technologies in place of conventional ones is substantial. Whether you're a home owner, architect, builder, business owner, or industry or utility ...

  • U.S. desalination industry grows since 2000; seen as essential to meeting supply needs

    With supplies of clean water becoming more scarce in certain areas and demand increasing, desalination is on the rise in the United States, water professionals told BNA. Half again as many municipal desalination plants were built between 2000 and 2010 as were built in the preceding three decades, according to research by water sector consultant Mike Mickley that was published in 2012 in the IDA ...

  • Two proposals for unlimited fresh water

    The world water crisis may be more serious than generally appreciated. One reason for this is that the main response has been to increase storage of rain rather than to increase the amount of fresh water. Another is that fossil groundwater has been widely seen as inexhaustible. Two fresh water collecting systems are outlined here and it is argued that they have no ultimate limitation, either by ...

  • Water and energy futures for Melbourne: implications of land use, water use, and water supply strategy

    This paper quantifies the effect of three policy levels on the water and energy futures of Melbourne, Australia. During a time of severe water shortages attributed to climate change, water strategies lacked consideration of energy consequences. Modeling, guided by urban metabolism theory, demonstrated that a compact urban form, reduced water consumption by 90 GL/a, compared with a sprawling ...

  • Ocean Thermal Energy and Water Production

    Introduction The scarcity of potable water is a growing problem worldwide, particularly in arid regions and among developing countries. Compounding this problem is the increasing contamination of freshwater sources, which comprise only about 2.5% of all water on Earth. Of this small portion, only 0.5% of the total fresh water available is found in easily accessible sources such as ...
