How To Take Out Salt From Water? | 5 Effective Ways

Clean drinking water is essential for human survival; however, with climate change and increasing pollution, the availability of clean water is becoming a growing concern. In many parts of the world, people have to rely on groundwater or desalinated seawater to meet their daily water needs, and desalination can be expensive.

Learning how to take out salt from water can be a lifesaving skill. Although the process may seem complicated, it is actually quite simple, and it can be done with readily available materials. In this article, we will walk you through several methods of extracting salt from water, which can be useful in emergencies or for people living in regions with limited access to clean water.

Here is How to Take Out Salt From the Water

Reverse Osmosis

Reverse osmosis is one of the most effective ways to purify and desalinate water. It pushes water through a semipermeable membrane under high pressure, allowing for the passage of molecules such as H2O but rejecting others like sodium and chlorine, which make up salt. This method removes up to 95% of other minerals from water sources, including magnesium, iron, lead, fluoride, copper, and chlorine.

I have been installing reverse osmosis systems in my home for years. Of all the available models on the market, I have found that SpringWell’s system is the best option for me. It produces clean and pure drinking water and takes away any risks associated with drinking contaminated water.

Moreover, it operates with minimal maintenance requirements over its lifetime efficacy is so far unmatched by any other system currently available. With reverse osmosis, I’m confident I’m providing my family with high-quality drinking water at a fraction of what expensive bottled varieties might offer.


The hard water in many homes can have a major negative impact on daily life, with appliances and fixtures becoming encrusted with scale over time. Fortunately, there are ways to address the issue of hard water. The process of softening water involves the removal and replacement of mineral content. Water softeners use a process known as ion exchange to remove the minerals, replacing them with small amounts of sodium ions instead.

Water conditioners also specialize in eliminating hard water by altering the mineral content so that it won’t cause scale buildup on pipes and other surfaces. Also known as salt-free water softeners, these systems do not add any extra sodium to the home’s drinking water supply– making them an attractive alternative for those avoiding an increased dietary sodium intake.

With all these different options available to homeowners today, it helps to take your time by learning the difference between salt versus salt-free water softener systems before investing money into one or another option.


The process of ion exchange works by replacing the mineral or metal ions found in water with other desired ions. The system uses a resin, such as Zeolite, to act as an exchange medium. The unwanted mineral or metal ions attach to the resin while sodium or other desired ions are released into the water.

Ion-exchange systems are usually installed at the main water line entering your home after the water meter, which is why they are sometimes referred to as point-of-entry (POE) systems.

The two tanks comprising the ion-exchange system contain the resin and the brine solution, respectively. When added to an existing supply of tap water containing mineral and metal particles, the brine solution acts as a source for sodium or other desired ions.

As these contaminants attach to the resin during this process, clean drinking water is released from the system throughout your house plumbing network without adversely affecting your health. This results in cleaner and healthier drinking water for you and your family.


The boiling process is an effective method for removing salt from drinking water. By heating the saltwater in a closed container, the water starts to boil and changes into vapor which is then collected with a condenser.

This process, similar to alcohol distillation, can be used when a more efficient way of desalination than solar stills is needed. Boiling requires a lot of heat energy input, and the process needs to be closely monitored not to overheat and crack any vessels holding the saltwater.

Once heated correctly, the water vapor condenses on another cooling container’s walls or surfaces and drips back into liquid form. The condensed liquid is then collected from this separate vessel without any salts or other minerals previously present in the source water. This technique allows many communities to access clean drinking water with minimal effort and time investment.

 Solar Still

Solar stills are a centuries-old method of removing evaporated salts from salt water. This desalination technique uses the sun’s natural power to separate the salts from water, producing fresh water that can be used for drinking or growing crops. While this method is useful in arid climates where a water source isn’t readily available, it takes time and effort to complete successfully.

Creating solar still begins with digging a hole in the ground that is big enough to contain the saltwater you want to be purified. Foliage such as seaweed and moss can be added for additional moisture before pouring into the saltwater.

Once that’s done, place a cup or bowl in the center of the hole and cover it with clear plastic tied down tightly over the edges. As sunlight hits it, warm air will become trapped underneath and slowly evaporate as condensation onto the plastic covering, leaving pure freshwater droplets that drip into your container below.

With lots of patience and proper temperature control, solar stills can produce up to 6 liters of fresh water daily from just one square meter of land.


Electrodialysis is a process that can be used to remove salt from water naturally. This process involves using an ion-exchange membrane to move the salt ions and other impurities across it when an electric charge is applied.

This method is highly effective in removing salts but not so much for other contaminants, including dirt or microscopic organisms. Researchers are working on making the process more efficient and reliable since current technology allows it to do so much faster than osmosis.

Another big advantage of electrodialysis compared to other natural desalination techniques is its ability to process large amounts of water at one time.

It can also become a great asset if there’s a need for large volumes of fresh drinking water in short amounts of time. To learn more about electrodialysis, you can look up online resources like YouTube videos to learn more about this process and how it works.

Sand and Gravel Filter

Sand and gravel filter systems are one of the most efficient methods for purifying water. This type of filter effectively traps dirt and other contaminants between the two materials as the water flows through.

The sand acts like an ultra-fine filtering agent that catches particles that may otherwise pass through unfiltered. With the addition of larger particles, such as those found in gravel, a multi-layered filtration system is created, eliminating far more particles than either material alone.

Before adding it to your container, the sand must be clean and free from potential contaminants. To ensure this, carefully wash your sand and gravel with soap and warm water to remove any debris or impurities before combining them in equal parts.

When you are done, ensure that both materials are completely dry before adding them together. Once added together in the right mix ratio, these two items form a powerful filter solution that can greatly improve the clarity and purity of drinking water.

Frequently Asked Questions [FAQs]

1. What Is The Easiest Way To Remove Salt From Water?

The easiest way to remove salt from water is by boiling it. Boiling causes the water to evaporate, leaving behind salt. This method works best when dealing with a small amount of water and large crystal-like grains of salt. Bring the salted water to a boil in a pot over medium heat on the stove. Once it reaches boiling point, reduce the heat and let the water simmer for a few minutes. The salt should begin to settle at the bottom of the pot and can then be skimmed off with a spoon or ladle.

2. Does Distillation Remove Salt From Water?

Yes, distillation removes salt from water. Distillation is a process that works by boiling the salted water and then collecting the steam as it rises and condenses. The steam is then cooled and collected in a separate container, leaving the salt and other contaminants behind. This method is highly effective for removing salt from the water and can purify large amounts of water.

3. How Do You Remove Salt From Water Cheaply?

Removing salt from water can be done cheaply by using a process known as desalination. Desalination removes salt and other minerals from the ocean or saline water to make it suitable for drinking and other uses. The most common technique to desalinate water is reverse osmosis (RO). This process involves pushing salty water through a semipermeable membrane, which allows the water molecules to pass through but not the salt. RO systems can be purchased relatively cheaply, making it an affordable option for those looking to remove salt from their water.

4. How Do You Separate Salt And Sand?

To separate a mixture of salt and sand, use filtration and evaporation. Filtration can remove sand from a combination of sand and salt solution. Sand remains on the filter paper as residue. By boiling the filtrate, common salt can be produced.

5. Does Salt Dissolve In Water?

Yes, salt does dissolve in water. Salt molecules are made up of positively and negatively charged ions, which attract each other and form a crystal lattice structure. When salt is added to water, the positive and negative ions separate from the lattice structure and becomes surrounded by water molecules, this causes the salt to dissolve into the water, forming a solution of salt and water.


Removing salt from water can be done using several methods, such as filtration, boiling, distillation, and desalination. These techniques vary in cost and efficiency and should be chosen depending on the desired outcomes. Ultimately, sand and gravel filters are one of the most efficient ways to purify water for drinking purposes.
