By usung desalination equipment. Either basically a fine filter that traps the salt on one side, letting the water pass through. Or by distilling the water, which also leaves the salt.

What material can be used to filter sea water
A ship floats on the sea due to the principle of buoyancy. The weight of the water displaced by the ship is equal to the weight of the ship, allowing it to float. This is because the density of the ship is lower than the density of water.
A sea has salty water so therefore it has a higher density than river water. The sea basically is "thicker water" so the ship will rise.
both.
No. You can melt ice or desalinate sea water to obtain sufficient drinking water.
no
It provided drinking water.
Drinking water can be made from sea water either by reverse osmosis filtering, or vacuum distillation, but both are too slow and expensive to be very useful.
The science clearly points out that drinking sea water in large amounts is very unhealthy. Drinking small quantities without ever offsetting it with fresh water is also very clearly unhealthy. As most times it would be impossible, if not extremely hard, to supplement sea water with a proper amount of fresh water in a survival situation, it is best to avoid it altogether.
Desalination plants convert sea water into drinking water by distillation.
yes it can be purified
