A view across a reverse osmosis desalination plant in Barcelona, Spain. Credit: James Grellier. You can try this at home! Dig a pit in the ground Place a bowl at the bottom of the pit that will be used to catch the condensed water Cover the pit loosley with a plastic sheet you can use stones or other heavy objects to hold it in place over the pit Be sure that the lowest part of the plastic sheet hovers directly over the bowl Leave your water "trap" overnight and water can be collected from the bowl in the morning Credit: Daniele Pugliesi.

Desalination is the process of turning salty ocean water into drinking water. So with million people lacking access to clean water and more areas facing severe droughts, could desalination be the silver bullet?
The Middle East has been a leader in desalination so far. Israel gets 40 percent of domestic water from desalination. These countries also have hardly any groundwater or fresh water sources so desalination is a case of innovation by necessity.
These countries make up the one percent of the world currently relying on desalination to meet water needs. But the UN predicts that by 14 percent of the world will rely on desalination to meet water needs. Desalination is the process of purifying saline water into a potable fresh water. Basically—turning ocean water into drinkable fresh water. Estimated reading time Time 4 to read.

There are stories of sailors who had survived by drinking small amounts of seawater. Credit: Kalle It has long been known that humans cannot keep themselves hydrated with salt water. Small amounts of seawater In the Second World War, shipwrecks were plentiful and there were stories of sailors who had survived by drinking small amounts of seawater.

That's about as much as two people in the U. But switch the source to a river or an aquifer , and the cost of a cubic meter of water can plummet to 10 to 20 cents, and farmers often pay far less. That means it's still almost always cheaper to use local freshwater than to desalinate seawater.
This price gap, however, is closing. For example, meeting growing demand by finding a new source of water or by building a new dam in a place like California could cost up to 60 cents per cubic meter of water. As such, this cost figure is expected to continue to rise, which is why California is now seriously considering desalination and why the city of Tampa, Fla.
The International Desalination Association says that as of there were about 13, desalination plants operating around the world. They pumped out approximately A lot of these plants are in countries like Saudi Arabia, where energy from oil is cheap but water is scarce. There are two basic methods for breaking the bonds in saltwater: thermal distillation and membrane separation. Thermal distillation involves heat : Boiling water turns it into vapor—leaving the salt behind—that is collected and condensed back into water by cooling it down.
