Seawater is full of salt that typically dehydrates the human body. But what if we could make seawater safer to drink? It turns out that we can and the process is called desalination. Desalination is a process that removes dissolved minerals including but not limited to salt from seawater, brackish water, or treated wastewater. A number of technologies have been developed for desalination, including reverse osmosis RO , distillation, electrodialysis, and vacuum freezing.

So why is seawater such an attractive water resource that we go through all those costly process to make it safe to drink? Here are a few reasons Seawater provides an unlimited, reliable water supply for coastal populations worldwide; brackish water is a plentiful, relatively drought-proof water resource for inland populations and reduces dependency on imported water. And, of all the Earth's water, 97 percent is salt water, only 1 percent is fresh water available for humans to drink, and 2 percent is frozen.

To date, only a limited number of desalination plants have been built along the California coast, primarily because the cost of desalination is generally higher than the costs of other water supply alternatives available in California e. Really, take some ocean water, put in it a pan, hopefully in the sun, and wait for the water to evaporate. Skip to main content. Search Search. Water Science School.

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.
