Humans cannot drink saline water, but, saline water can be made into freshwater, for which there are many uses. The process is called "desalination", and it is being used more and more around the world to provide people with needed freshwater. Consequently, can you filter salt water to make it drinkable?
Desalination is the process of purifying saline water into a potable fresh water. Basically–turning ocean water into drinkable fresh water. Reverse osmosis and distillation are the most common ways to desalinate water. Reverse osmosis water treatment pushes water through small filters leaving salt behind.
Beside above, what happens if you drink only salt water? Human kidneys can only make urine that is less salty than salt water. Therefore, to get rid of all the excess salt taken in by drinking seawater, you have to urinate more water than you drank. Eventually, you die of dehydration even as you become thirstier.
Similarly, you may ask, how do you make salt water drinkable?
Thermal distillation involves heat: Boiling water turns it into vapor—leaving the salt behind—that is collected and condensed back into water by cooling it down. The most common type of membrane separation is called reverse osmosis. Seawater is forced through a semipermeable membrane that separates salt from water.
Does boiling salt water make it drinkable?
A floating solar still is used to desalinate small amounts of seawater, using evaporation and condensation. No, don't take us literally! Humans cannot drink saline water.

Does boiling water make it drinkable?
Boiling. If you don't have safe bottled water, you should boil your water to make it safe to drink. Boiling is the surest method to kill disease-causing organisms, including viruses, bacteria, and parasites. Can LifeStraw filter urine?
LifeStraw filters do not remove dissolved salts and are not designed to be used to drink non-diluted urine. Because of this, we do not recommend drinking urine with the LifeStraw in even low amounts. Is there a machine that turns saltwater into freshwater?
developed by a london-based start-up, QuenchSea is a portable, low cost desalination device that turns saltwater into fresh water. to do so, the apparatus combines a hydraulic system, a triple pre-filtration process, and a small reverse osmosis membrane to desalinate seawater into freshwater using human power only.

Can you drink rain water?
It is possible, therefore, for us to drink untreated rainwater. This is because rainwater is pure, distilled water evaporated from the sun - nothing else. However, when rainwater falls from the sky, substances from the air and land melt into the rainwater. This water (groundwater) is relatively safe for drinking. Why are oceans salty?
Salt in the sea, or ocean salinity, is mainly caused by rain washing mineral ions from the land into water. Carbon dioxide in the air dissolves into rainwater, making it slightly acidic. When rain falls, it weathers rocks, releasing mineral salts that separate into ions. What is salt water useful for?
About five percent of the Nation's saline water was used for mining and industrial purposes. Perhaps one of the most important uses of saline water, and something that will become more important in the future, is that it provides a ample supply of water that can be desalinated and turned into fresh water. Why you shouldn't drink salt water?
Why can't people drink sea water? Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body's kidneys normally remove excess salt by producing urine, but the body needs freshwater to dilute the salt in your body for the kidneys to work properly. What happens if you drink pee?
When urine passes through the urinary tract, it becomes contaminated with bacteria. Drinking urine, whether your own or someone else's, introduces bacteria into your system that can cause gastrointestinal problems or other infections. What happens if you drink blood?
Drinking blood won't have the same therapeutic effect. Consuming more than a few drops — like from a busted lip — may actually make you nauseous and result in vomiting. If you do go on to ingest a significant amount, hemochromatosis is possible. What happens if you drink salt water on an empty stomach?
Drinking salt water on an empty stomach may cause nausea and vomiting. You may also experience cramping, bloating, and dehydration. Colon cleansing in general may cause an electrolyte imbalance due to the rapid loss of sodium and fluids. What happens if you swallow salt water when gargling?
The salt functions as a magnet for water. It's good for symptomatic relief. And you end up swallowing some of it, so it's sort of helping you with dehydration as well.” (To clarify: The swallowing bit is incidental -- it just tends to happens when gargling. You're not meant to actually drink the warm salt water.) How much salt water is lethal?
The lethal dose was estimated to be less than 10 g of sodium (<5 teaspoons of salt) in two children, and less than 25 g sodium in four adults (<4 tablespoons of salt). How long can you live without water?
As a general rule of thumb, a person can survive without water for about 3 days. However, some factors, such as how much water an individual body needs, and how it uses water, can affect this. What is salt poisoning like?
Salt poisoning typically results in a feeling of confusion and jitteriness; more severe degrees of intoxication can cause seizures and coma. Death can result if medical intervention is not forthcoming. These symptoms are generally a consequence of hypernatremia—an abnormally high sodium level in the blood. What happens if you drink too much water?
When you drink too much water, you may experience water poisoning, intoxication, or a disruption of brain function. This happens when there's too much water in the cells (including brain cells), causing them to swell. When the cells in the brain swell they cause pressure in the brain.
