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 ...
Reverse osmosis is most commonly known for its use in drinking water purification from seawater, removing the salt and other effluent materials from the water molecules. [2] As of 2013 the world's largest RO desalination plant was in Sorek, Israel, outputting 624 thousand cubic metres per day (165 million US gallons per day). [3]
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.

At its most basic, desalination is the process of removing salt from water. But for Arizona, it will be much more complicated because it's not just about the water.
The salts do not fit in the crystal structure of water ice, so the salt is expelled. Since the oceans are salty, this process is important in nature. Salt rejected by the forming sea ice drains into the surrounding seawater, creating saltier, denser brine. The denser brine sinks, influencing ocean circulation.
Brine treatment involves removing dissolved salt ions from the waste stream. Although similarities to seawater or brackish water desalination exist, industrial brine treatment may contain unique combinations of dissolved ions, such as hardness ions or other metals, necessitating specific processes and equipment.
The preheated seawater then enters the first stage of the MSF system. Flashing: In each stage, the preheated seawater is passed through a flash chamber, where its pressure is rapidly reduced. This sudden drop in pressure causes the water to flash into steam, leaving behind concentrated brine with high salt content.
Salt deposition from sea spray is correlated with a decrease in plant height and significant scarring, shoot reduction, stem height decrease, and tissue death on the windward side of shrubs and trees. [30] [31] Variation in salt deposition also influences competition between plants and establishes gradients of salt tolerance. [30]
