Can Salt Water or Seawater Be Boiled To Render It Drinkable?

Last Updated: September 16, 2022

Only around 2.5% of the Earth’s surface is covered by freshwater, about 71% of all water. Naturally, this indicates that seawater or saltwater makes up the great bulk of the water on Earth.

Seawater must be sterilized, and remove the salt to make it drinkable. Because it puts your organs under a lot of strain, drinking lots of seawater can be fatal.

To remove unwanted salt, your kidneys must work overtime, and water containing such a high amount of salt can never rehydrate you. With simple tools, there are several techniques to separate the water first from salt, one of which requires heating the water. Seawater must be boiled, and the steam must be collected to distill it; you cannot simply boil the seawater.

Risks Associated With Consuming Seawater

There is salt in seawater. Human cells absorb salt and water when they consume seawater. Although a tiny amount of salt can be taken by humans without harm, seawater has a considerably higher amount of salt than the body may be able to metabolize.

Additionally, we drink liquids and the salt we eat as a component of our daily diets, which does assist in hydrating our body and maintaining the intake of salt at a healthy level. Although sodium is necessary for the body’s chemical processes and balances to function, excess sodium may be fatal. Salt is a compound that is necessary for living cells to function.

Human kidneys can only excrete urine that is a tiny bit less salty compared to salt water. Due to the high salt absorbed from drinking seawater, you need to excrete more water than you previously did. You start to feel thirstier, but eventually, dehydration kills you.

Effects Of Too Much Salt On People

Here are significant indicators that you are ingesting too much salt.

#1 A Lot Of Urination Is Required

A common indicator that you are eating too much salt is urinating. Most of the time, one may have an urgent desire to urinate throughout the night. On the other hand, it can also be a sign of numerous other illnesses, including type 2 diabetes, UTIs, and overactive bladders. To determine the precise underlying cause, conduct a test. But it could also be a result of eating too much salt.

#2 Prolonged Thirst

Too much salt consumption can make you frequently dehydrated. Foods with a high sodium level disrupt the fluid balance in your body, which is why this occurs. Water consumption is the greatest strategy to make up for this. Your body is still trying to tell you that you need to drink more water to get the balance of salts back in your body.

#3 Strange Areas Of Swelling

Swelling in numerous body areas can result from too much salt. You can feel bloated in the morning because of this. On the fingers and in the ankle area, there is swelling. Edema is the term for this swelling that results from an overabundance of fluid in the body’s tissues.

Edema is a sign of a health problem that lies beneath the surface or indicates that you are eating too much salt. Cutting back on your sodium consumption is an easy fix for this.

#4 The Food You Eat Is Monotonous And Bland

Are you compelled to season your food with more salt on occasion? Does bland, monotonous food constantly turn you off? You probably consume too much salt because of your habits, then. You must add extra salt to food since your taste buds become accustomed to that flavor over time.

#5 Regular Mild Headaches

Occasionally, do you have slight headaches? Most likely, dehydration is what’s causing these headaches. Dehydration brought on by ingesting too much salt may cause headaches that come and go quickly. For relief from these headaches, drink a lot of water.

#6 You Want Salty Meals

Your taste buds will become addicted to the same flavors after they become accustomed to salty ones. You suddenly crave salty snacks like chips, salted peanuts, and other salty foods.

#7 Harmful Bacteria

They claim that Vibrio bacteria are normally present in salt water, and those healthy individuals are rarely affected. Vomiting, diarrhea, and abdominal pain are symptoms. If the bacteria enter the bloodstream, they cause symptoms such as fever, chills, low blood pressure, and blistering skin lesions.

Various Techniques For Removing Salt From Saltwater

#1 Use Distillation To Separate Salt From Water

The salt will remain solid after the water has been boiled or evaporated. If you want to save water, distillation is a possibility. Salt has a far greater boiling point than water, which explains why this is effective. The saltwater can be boiled in a saucepan with a lid to separate water and salt at home.

Adjust the lid’s position so that any condensation on its interior will flow down its surface and into a separate container as it descends the side. Congratulations! The distilled water you just created. The salt will stay in the pot after all the water has evaporated.

#2 Evaporation Is Used To Separate Salt From Water

Just more slowly, evaporation operates in the same way as distillation. A shallow pan should contain salt water. The salt will not be lost as the water evaporates. You can hasten the process by turning up the heat or sprinkling dry air over the liquid’s surface.

Pouring the salt water onto a sheet of dark construction paper or even a coffee filter is an alternative to this technique. Rather than scraping them from the pan, retrieving the salt crystals is simpler.

#3 Alternative Techniques For Salt And Water Separation

Using reverse osmosis is another method for separating salt from water. This procedure involves pushing water against a porous filter, which raises the salt content of the filtrate as it exits. Reverse osmosis pumps are rather pricey, despite the effectiveness of this approach. When camping or at home, they can be employed to cleanse water.

You can purify water with electrodialysis. In this case, a porous membrane separates the positively and negatively charged anodes and cathodes in water. The positive sodium ions and the negative chlorine ions are drawn to the anode and cathode, respectively, by applying an electric current, leaving behind the filtered water. The water may still include uncharged pollutants. Therefore this method does not guarantee that it is safe to consume.

Decanoic acid is added to salt water as part of a chemical process to separate the two substances. Heating occurs in the solution. In the process of cooling, salt precipitates out of the solution and settles on the container’s bottom. It is possible to remove the water after the water as well as decanoic acid separate into layers.

Conclusion

Seawater cannot be made drinkable by simply boiling it. You require the salts and other undesirables to be left behind as the water vapor evaporates. It’s a rather easy technique that you may undertake with minimal equipment.
