Evaporation.
You boil the salt water and collect the droplets from the steam which is then called distilled water.

The technical term is water de-salinization or reverse osmosis. Osmosis being when salt joins with water on the molecular level. But you could call it distillation and be fine.
Now, I can't draw a diagram so I'll try to explain it.
Beaker A sits on a burner filled with salt water and connected to a bent glass tube that has the open end hanging over beaker B. Both beakers and the tube form a triangle. When the water in beaker A boils, it turns to steam. The steam rises and enters the tube where it cools and reforms as a liquid. The salt, which contrary to what others have said, does NOT evaporate, it stays in Beaker A. The liquid, sans salt crystals, then drips from the tube into Beaker B. This may need to be repeated several times to ensure complete distillation but for all intents and purposes that is how it is done.

Distillation; Boil the water and have over the container a hood connected to a tube that will carry the steam to another container as far away from the boiler as possible. If this other container is cooler than the steam, the water condenses and you have distilled water. Tastes dreadful but does the job, salt left in the boiler can actually be used for the table so its a win win.

By boiling the saltwater, but a good idea is to somehow catch the steam with a bent peice of saran wrap and let it drip into a receptacle, then dump out the thick, mushy salt from the pot and repeat if necessary!!! I learned this from a island survival class!!!

quite a few ways.
electrolysis
boiling the water and condensing the steam
reverse osmosis pump

make the water evaporate.
put plastic or something over the [whatever you have the water in] so the steam collects and runs down the side into some sort of container.

Many different ways if you have a huge lab at your disposal then you can use reverse osmosis. But if you are an average joe as i would suspect you can boil it. see the website for a picture of how to do it.

set up a distillation apparatus, boil the water over, collect it in a separate container, the salt will stay on the other other end.
