How to Make Seawater Drinkable

Sea salt is a common ingredient in many dishes, but it’s also the single most important element for people to drink as plain water. It can be difficult and expensive to extract fresh sea salt from seawater without using electricity or chemicals, which makes drinking much more accessible.

The “how to make seawater drinkable survival” is a post about how to make seawater drinkable. The author does not mention what kind of water filter the article is talking about, but it could be a gravity-based or distillation-based filter.

The fact that a person may be adrift at sea, surrounded by water, and die of dehydration is one of the world’s great ironies. It’s not because you can’t drink salt that makes seawater so dangerous to consume. We consume salty liquids all the time, such as soups and stews, and our kidneys have no trouble filtering and digesting it. However, this procedure works because we also drink a lot of freshwater, which dilutes the overall amount of salt in our bodies. It’s a delicate balancing act. 

When you just drink saltwater, that equilibrium is thrown out of whack. Your kidneys work overtime to remove salt from your body and force you to pee. You lose water every time you pee, and no matter how quickly you drink, you’ll never catch up. 

Desalination (removal of salt from water) is the only technique to make saltwater safe to drink in survival situations. Basic evaporation is the most basic technique of desalination. Consider what you learned in science class in elementary school: You were undoubtedly taught that the sun warms the ocean’s surface water, causing it to evaporate. The salt is left behind after water evaporates. The wet air rises, cools, forms clouds, and eventually rains if there is enough of it. 

To assist you catch freshwater in a container to drink, the desalination procedure below uses the evaporation and condensation processes. All you’ll need is a huge plastic bottle and a can of Coke to get started. Keep in mind that you’ll need a lid for your plastic bottle. Otherwise, the saltwater will evaporate and escape through the top.

How do you make sea water drinkable?

A: This is a very complicated question. To answer it, I would need to know what you mean by sea water.

Can you make ocean water drinkable by boiling it?

A: Unfortunately, it is impossible to make ocean water drinkable by boiling. The heat of the fire would evaporate the salt and other minerals in the sea water making it undrinkable.

How do you make sea water drinkable in emergency?

A: If you want to make sea water drinkable, there are a few solutions. The first option is to distil the salt out of it which will leave behind mostly fresh water with some trace amounts of other minerals or impurities that might be difficult for your bodys systems to process. You could also boil the water in order to evaporate away certain chemicals and then cool this down into drinking-quality liquid using ice cubes instead of air cooling methods
