Its use is practical only in warm climates where the evaporation rate exceeds the precipitation rate, either annually or for extended periods, and ideally, where there are steady prevailing Continued
The history of solar powered water distillation started with Aristotle, already back in the 4 th century BC, described a technique of solar powered water distillation. However, it was not before late 19 th century, that the first large scale solar water distillation plant was built. This plant, loed in Chile, supplied as much as 20 000
Solar evaporation ponds in the Salt Valley of Añana, Spain A salt evaporation pond is a shallow artificial salt pan designed to extract salts from sea water or other brines . Natural salt pans are geological formations that are also created by water evaporating and leaving behind salts.
While evaporation ponds have long been used for salt production in many parts of the world, the disposal of concentrate from desalination plants in inland areas using evaporation ponds is of much
Performance will be always better than an evaporation pond, as boundary conditions do not affect the process (high humidity, rain, low wind days) Clean water is recovered after evaporation. Independent from water or brine quality, salinity or pH. Modular solar and thermal systems, allowing wide scalability.

For example, if the plant is standing in a desert, the internal temperature and the resulting production is higher compared to if the plant is standing in a snow biome. The advanced version works independently from the ambient temperature, and achieves much higher temperatures and production rates thanks to the energy of the solar modules.
salt plant dates back to the midtwenties. ESCHER WYSS manufactured the compressors in their own workshops and were also asked to fabrie the evaporator for this plant which recovered salt from brine on a continuous basis.

The Grantsville Plant produces Solar Salt, which is the oldest method of salt production.
Solar salt purity is going to typically be greater than 99.5% sodium chloride. Evaporation is a more expensive process than just digging the salt directly out of the ground. Solar salt is always going to be more expensive than rock salt. Do we get any value from that more expensive, higher purity? Well, it depends on how you are using it.
