  2. 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.

  3. Solar still - Wikipedia

    en.wikipedia.org/wiki/Solar_still

    In a solar still, impure water is contained outside the collector, where it is evaporated by sunlight shining through a transparent collector. The pure water vapour condenses on the cool inside surface and drips into a tank. Distillation replicates the way nature makes rain. The sun's energy heats water to the point of evaporation.

  4. Solar-powered desalination unit - Wikipedia

    en.wikipedia.org/wiki/Solar-powered_desalination...

    Indirect solar desalination systems comprise two sub-systems: a solar collection system and a desalination system. The solar collection system is used, either to collect heat using solar collectors and supply it via a heat exchanger to a thermal desalination process, or to convert electromagnetic solar radiation to electricity using photovoltaic cells to power an electricity-driven ...

  5. Solar pond - Wikipedia

    en.wikipedia.org/wiki/Solar_pond

    Diagram of a solar pond. A solar pond is a pool of saltwater which collects and stores solar thermal energy. The saltwater naturally forms a vertical salinity gradient also known as a "halocline", in which low-salinity water floats on top of high-salinity water. The layers of salt solutions increase in concentration (and therefore density) with ...

  6. Multiple-effect distillation - Wikipedia

    en.wikipedia.org/wiki/Multiple-effect_distillation

    Does not need pre-treatment of sea water and tolerates variations in sea water conditions; Highly reliable and simple to operate; Low maintenance cost; 24-hour-a-day continuous operation with minimum supervision; Can be adapted to any heat source, including hot water, waste heat from power generation, industrial processes, or solar heating.

  7. Salt water chlorination - Wikipedia

    en.wikipedia.org/wiki/Salt_water_chlorination

    Salt water chlorination is a process that uses dissolved salt (1000–4000 ppm or 1–4 g/L) for the chlorination of swimming pools and hot tubs.The chlorine generator (also known as salt cell, salt generator, salt chlorinator, or SWG) uses electrolysis in the presence of dissolved salt to produce chlorine gas or its dissolved forms, hypochlorous acid and sodium hypochlorite, which are already ...

  8. Multi-stage flash distillation - Wikipedia

    en.wikipedia.org/wiki/Multi-stage_flash_distillation

    Such plants can operate at 23–27 kWh/m 3 (appr. 90 MJ/m 3) of distilled water. [5] Because the colder salt water entering the process counterflows with the saline waste water/distilled water, relatively little heat energy leaves in the outflow—most of the heat is picked up by the colder saline water flowing toward the heater and the energy ...

  9. Crescent Dunes Solar Energy Project - Wikipedia

    en.wikipedia.org/wiki/Crescent_Dunes_Solar...

    The project includes 10,347 heliostats that collect and focus the sun's thermal energy to heat molten salt flowing through an approximately 656-foot (200 m) tall [13] solar power tower. Each heliostat is made up of 35 6×6 feet (1.8 m) mirror facets, yielding a heliostat overall usable area of 1,245 square feet (115.7 m 2 ).
