  2. Desalination - Wikipedia

    en.wikipedia.org/wiki/Desalination

    Since 1975, desalination technology has seen significant advancements, decreasing the average cost of producing one cubic meter of freshwater from seawater from $1.10 in 2000 to approximately $0.50 today. Improved desalination efficiency is a primary factor contributing to this reduction.

  3. Multi-stage flash distillation - Wikipedia

    en.wikipedia.org/wiki/Multi-stage_flash_distillation

    Multi-stage flash distillation (MSF) is a water desalination process that distills sea water by flashing a portion of the water into steam in multiple stages of what are essentially countercurrent heat exchangers. Current MSF facilities may have as many as 30 stages.

  4. Water conservation - Wikipedia

    en.wikipedia.org/wiki/Water_conservation

    This makes it necessary to evaluate the impacts of seawater desalination and to find ways to improve desalination technology. Current research involves the use of experiments to determine the most effective and least energy intensive methods of desalination. [38] [39] [40] Sand filtration is another method used to treat water. Recent studies ...

  5. Freshwater salinization - Wikipedia

    en.wikipedia.org/wiki/Freshwater_salinization

    Human interaction accelerates rates of primary salinization. Land development, like construction and mining , causes compounds found in bedrock to be released from their tight locations and come to the surface, which are then exposed to accelerated rates of weathering, eventually leading to leaching ions in nearby water sources.

  6. Vapor-compression desalination - Wikipedia

    en.wikipedia.org/wiki/Vapor-compression_desalination

    The effect of compressing water vapor can be done by two methods. The first method utilizes an ejector system motivated by steam at manometric pressure from an external source in order to recycle vapor from the desalination process. The form is designated ejectocompression or thermocompression.

    In June 2018, a third desalination plant, the Tuas Desalination Plant (TDP), was opened. [52] Functioning also as a test bed for energy saving technology, the plant can produce 30 million imperial gallons (140,000 m 3) of water per day. Together, desalinated water from SingSpring, Tuaspring and the Tuas Desalination Plants can meet up to 30% of ...

  8. Environmental issues in the United Arab Emirates - Wikipedia

    en.wikipedia.org/wiki/Environmental_issues_in...

    Landscape of United Arab Emirates Environmental issues in the United Arab Emirates (UAE) are caused by the exploitation of natural resources, rapid population growth, and high energy demand. The continuing temperature rise caused by global warming contributes to UAE's water scarcity, drought, rising sea level, and aridity. The UAE has a hot desert climate, which is very vulnerable to the ...

  9. Solar desalination - Wikipedia

    en.wikipedia.org/wiki/Solar_desalination

    The process can be categorized based on the type of solar energy source utilized. In direct solar desalination, saline water absorbs solar energy and evaporates, leaving behind salt and other impurities. An example of this is solar stills, where an enclosed environment allows for the collection and condensation of pure water vapor.
