Question

Is there a way to make sea water into healthy drinking water.

Answer 1

Most certainly! The answer just depends upon how much time and/or money you have to spend. In fact, there are several options for purifying sea water.

The first option has been around for some time, and that is to distill the sea water. This is done by boiling the water and then condensing it (cooling it). This option requires a source of energy to heat the water, and a way to trap and deliver the steam rising from the heated sea water. The trapped steam that collects is perfectly drinkable water.

The next alternative is filtration. Filtration mechanically seperates the salt (and other materials) from the water molecules. The options include reverse osmosis, microfiltration, ultrafiltration, and nanofiltration. The filters include gravity filters, pressure filters, side stream filters, and continuous rotary filters. The only drawback to filters is that they need to be replaced. The rate at which they need to be replaced depends upon the amount filtered and the filter being used. So filtration of sea water on large scales is expensive, and not often used.

I hope that answers your question!

Answer 2

Yes, there are methods to obtain tap and drinking water.
Some island like Aruba or countries like Saudi Arabia use reverse osmosis. The water in this places is expensive.
In Israel they use solar energy to evaporate the water and obtain water for agriculture.
It is also possible to separate the water and brine by freezing: cooling to 28 F. the pure water start to separate as ice in the surface of the seas.

Answer 3

Yes,de-salianization.You boil the water and convert it to steam,capture it in a condenser and cool it down again.The device is called a "Still" for distilation.The Saudi Arabians built some hugh ones in the 1960's for drinking water.You also use a small one in a drinking water lab to avoid contamination of the samples when diluting concentrations.Hikers often use a reverse osmosis membrane filter,but I think it's only usable for freshwater.

Answer 4

Dig a hole, and place a container at the bottom of the hole.

Then, get some water-proof materiel and fill it with water. Suspend that over the hole and eventually condensation will form over the surface of the water-proof materiel and will drop and collect into the container at the bottom. Fresh drinking water!

Answer 5

Absolutely, ships and submarines have desalination plants aboard to convert seawater into potable water. Some countries in arid regions have larger similar plants.

Answer 6

Yes. The process is called desalination. It requires a lot of energy, therefore, it presently is not a viable process for production of large quantities of fresh water.
