How do you separate salt from sea water?


Quick Answer

Drinkable water can be obtained from seawater by removing salt through a distillation process. Distillation is a simple process that can be done on a small scale as a personal project or on a large scale as a desalination plant that provides drinking water for many. Despite its simplicity, desalination is an expensive process compared to getting drinking water from fresh water sources.

Full Answer

When salt water is heated, the water will evaporate and dissipate in the air. To just obtain the salt from the water, boil the water until only salt remains. To recover the water for later use, channel the water vapor through a tube where it can condense and drip into a container. While the water will be warm, it will be free of salt.
