2. Desalination - Wikipedia

   en.wikipedia.org/wiki/Desalination

   Freeze–thaw desalination (or freezing desalination) uses freezing to remove fresh water from salt water. Salt water is sprayed during freezing conditions into a pad where an ice-pile builds up. When seasonal conditions warm, naturally desalinated melt water is recovered. This technique relies on extended periods of natural sub-freezing ...

3. Multiple-effect distillation - Wikipedia

   en.wikipedia.org/wiki/Multiple-effect_distillation

   Multiple-effect distillation or multi-effect distillation (MED) is a distillation process often used for sea water desalination. It consists of multiple stages or "effects". In each stage the feed water is heated by steam in tubes, usually by spraying saline water onto them.

4. Multi-stage flash distillation - Wikipedia

   en.wikipedia.org/wiki/Multi-stage_flash_distillation

   The heat added in the brine heater usually comes in the form of hot steam from an industrial process co-located with the desalination plant. The steam is allowed to condense against tubes carrying the brine (similar to the stages). [citation needed] The energy that makes possible the evaporation is all present in the brine as it leaves the heater.

5. Multiple-effect humidification - Wikipedia

   en.wikipedia.org/wiki/Multiple-effect_humidification

   Multiple-effect humidification (MEH) is a method used for thermal desalination of sea water. It uses multiple evaporation – condensation cycles at separate temperature levels to minimize the total energy consumption of solar humidification processes.

6. Solar desalination - Wikipedia

   en.wikipedia.org/wiki/Solar_desalination

   RO is the most common desalination process due to its efficiency compared to thermal desalination systems, despite the need for water pre-treatment. [39] Economic and reliability considerations are the main challenges to improving PV powered RO desalination systems. However, plummeting PV panel costs make solar-powered desalination more feasible.

7. Freezing - Wikipedia

   en.wikipedia.org/wiki/Freezing

   Freezing is a common method of food preservation that slows both food decay and the growth of micro-organisms. Besides the effect of lower temperatures on reaction rates, freezing makes water less available for bacteria growth. Freezing is a widely used method of food preservation. Freezing generally preserves flavours, smell and nutritional ...

8. Vapor-compression desalination - Wikipedia

   en.wikipedia.org/wiki/Vapor-compression_desalination

   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. Using the second method, water vapor is compressed by means of a mechanical device, electrically driven in most cases.

9. Solar humidification - Wikipedia

   A Desalination Greenhouse using all of the effects in all categories, with an emphasis on the optimized combination of the effects including synergies, is the IBTS Greenhouse. The Global water cycle also includes all sub-effects of HDH, like increased evaporation over the oceans surface and surface increase by wind, making the generation of ...
