Not easily.
Evaporation does not require much energy, but it is very slow.
Distillation requires the brine be boiled. This takes a lot of energy, both to heat the brine and then to cause the vaporization. Some of this heat requirement can be recycled by using the steam produced by the brine as a heat transfer media.
Reverse osmosis requires no heat input, but employs a strong vacuum (meaning big pumps) acting on a membrane to selectively pull water through.
Whatever the case, the water is still must go through the normal purification processes all drinking water must.

Distillation. Reverse osmosis.

By evaporation. Only the water evaporates. The salt remains in the ocean.

Evaporate it, and then quickly condense it (turn it onto a liquid onto a cold object)- and collect the water. The salt will not evaporate, as it has a higher boiling point.

Through distillation.

Commercially its by reverse osmosis. Distillation would be WAY too expensive.

It can be distilled through evaporation

Two ways:
1. by freezing it
2. by distilling it

You are too lazy to google this for yourself? My, look at all the answerers who must think they are too clever, here!

Every time I pee in it, it becomes a little bit less salty.
