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 ...
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 ...
The desalination process's energy consumption depends on the water's salinity. Brackish water desalination requires less energy than seawater desalination. [85] The energy intensity of seawater desalination has improved: It is now about 3 kWh/m 3 (in 2018), down by a factor of 10 from 20-30 kWh/m 3 in 1970.
Solar desalination is a technique that harnesses solar energy to convert saline water into fresh water, making it suitable for human consumption and irrigation. The process can be categorized based on the type of solar energy source utilized.
China is working to meet the country's growing demand for fresh water by building and improving desalination plants. In doing so the nation is on a path to growing the next big industry, and ...
Geothermal desalination refers to the process of using geothermal energy to power the process of converting salt water to fresh water. The process is considered economically efficient, and while overall environmental impact is uncertain, it has potential to be more environmentally friendly compared to conventional desalination options.

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.
In CDI, the energy cost per volume of treated water scales approximately with the amount of removed salt, while in other technologies such as reverse osmosis, desalination energy scales roughly with volume of treated water. This makes CDI a viable solution for desalination of low salt content streams, or more specifically, brackish water.
