How to Make Salt Water Drinkable: A Detailed Guide

Learn the Secrets to Making Salt Water Safe to Drink

Welcome, reader, to our comprehensive guide to making salt water drinkable. In this article, we will explore the process of turning the ocean’s salty water into safe and drinkable water, which can be a lifesaving technique in many situations.


Water is a vital resource for human life, and access to clean and potable water is crucial for survival. Unfortunately, nearly one-third of the world’s population lacks access to safe drinking water, which increases the risk of water-related diseases and illnesses.

The world is covered in more than 70% of water, but only a tiny fraction of this is freshwater that is drinkable. Drinking salt water is not recommended as it can lead to dehydration as our bodies cannot process saltwater. Hence in this article, we will discuss different techniques that can be used to turn salt water into drinkable water.

How to Make Salt Water Drinkable – The Process

There are several methods that can be used to make salt water drinkable, and each of them has its advantages and disadvantages. Before we dive into each method, let’s discuss the process of removing salt from water in general.


Desalination is the process of removing salt and other minerals from seawater, making it safe to drink. There are two primary methods of desalination: distillation and reverse osmosis.


Distillation involves heating the saltwater to create steam that can be captured and condensed, leaving behind salt-free water. The process requires a lot of energy and is not very efficient, making it expensive to operate on a large scale.

Reverse Osmosis

In reverse osmosis, seawater is forced through a semipermeable membrane that allows water molecules to pass through while trapping the salt and other impurities. Reverse osmosis is considered more efficient than distillation, but it also requires a significant amount of energy.

Solar Distillation

Solar distillation is a simple and low-tech method of desalination that uses the sun’s energy to evaporate saltwater and collect fresh water through condensation. This method is cost-effective, but it’s not practical in areas with low sun exposure or during the night.

Advantages and Disadvantages of Making Salt Water Drinkable


Advantages Explanation
Available Source Can be found in abundance in oceans.
Cost-effective Desalination is a cost-effective method for producing clean water in the long run.
Lessens Burden on Freshwater Sources By having an alternate source of drinking water, it helps lessen the burden on freshwater sources, resulting in a more sustainable source of freshwater.
Reducing Negative Environmental Impact Lessens the negative environmental impact of freshwater extraction.


Disadvantages Explanation
Costly Process Desalination is a costly process and requires energy resources to operate.
Environmental Impact Desalination plants can have a negative environmental impact on marine life and habitat, as well as disrupt the natural flow of water.
High Concentration of Minerals The desalination process can lead to a high concentration of minerals in the water, which can be harmful to human health in the long run.
Not Suitable for Agriculture The desalination process cannot produce enough water to support agriculture practices in the long run.


1. Can all types of saltwater be made drinkable?

Not all types of saltwater can be made drinkable. There are some types of water that contain high levels of toxins that are impossible to remove through desalination. In addition, polluted water is not safe to drink even after desalination.

2. Can I use a simple filter to remove salt from saltwater?

No, a simple filter cannot remove salt from saltwater. Salt molecules are smaller than the water molecules and cannot be trapped by a filter.

3. Can I make saltwater drinkable by boiling it?

No, boiling saltwater only makes it safe to drink in that moment, but the salt stays in the water. So, you will still be dehydrated after drinking it.

4. Is it safe to drink desalinated water?

Yes, desalinated water is safe to drink, but it can have a high concentration of minerals and salts, which can be harmful to human health in the long run.

5. What happens to the salt that is removed from the water?

The salt is typically disposed of in a landfill or sold as industrial salt.

6. Can desalinated water be used for agriculture?

Desalinated water is not suitable for agriculture in the long run because it requires too much energy to produce enough water for agricultural activities.

7. Can desalination be done at home?

No, desalination is a complex process that requires specialized equipment and expertise, making it impractical for home use.

8. Is solar distillation a feasible method of desalination?

Solar distillation is a simple and low-tech method of desalination that can be used in areas with high sun exposure, but it’s not practical in areas with low sun exposure or during the night.

9. Can desalination plants harm marine life?

Yes, desalination plants can harm marine life and habitat, as well as disrupt the natural flow of water.

10. How much energy does desalination require?

Desalination requires a significant amount of energy, which makes it a costly process.

11. How long does the desalination process take?

The desalination process can take several hours to days, depending on the method and the volume of water being processed.

12. Is desalination the only solution to water scarcity?

No, desalination is not the only solution to water scarcity, there are other solutions such as conservation, rainwater harvesting, and efficient irrigation practices.

13. Can desalination help mitigate the effects of drought?

Yes, desalination can help mitigate the effects of drought by providing an alternative source of water.


In conclusion, making salt water drinkable can be a complex process, but it is essential for survival in certain situations. There are different methods available for desalination, each with its advantages and disadvantages. However, it is crucial to keep in mind that desalination is not the only solution to water scarcity and other methods like conservation should be prioritized.

In our world, where freshwater sources are becoming scarce day by day, it is high time that we take steps towards saving and conserving water for a sustainable future. So, let’s act fast and work together towards a future where clean water is accessible to everyone.
