How to Turn Salt Water Into Drinking Water
Documentation Download Documentation Download Documentation Desalination is the process of eliminating salt from seawater, which may be important in your location if there is a scarcity of safe drinking water. You may also need to do this if you ever find yourself stuck somewhere without access to fresh, salt-free water at any point. There are a variety of methods for removing salt from water and converting it into potable drinking water.
- 1 Get a big saucepan with a lid and an empty drinking cup. 2 Put the pot on the stove and turn it on. In order to store a significant volume of freshwater, the glass should be large. Make sure the glass is short enough so that you can still fit it inside the pot while the cover is still on the pot.
- Prepare the dish in a pot with a lid that is intended to be cooked on the stovetop. Because certain varieties of glass may explode when exposed to heat, it is best to use a Pyrex or metal cup instead. Plastic has the potential to melt or distort.
- 2Ladle a little amount of seawater into the pot gently. Make sure not to overfill the pot. Stop long before the water level in the glass reaches the opening of the container. This will assist in ensuring that no seawater spills into the glass when it is being heated to boiling temperature. You don’t want any saltwater to get into the drinking glass, because that will contaminate the newly created fresh water. Advertisement
- s3 Place the pot cover on top of the pot and turn it upside down. As the water vapor condenses, it will drip into the drinking glass, allowing the water to be consumed. The pot lid should be placed such that its highest point, or handle, is pointing down toward the glass and is directly above the glass.
- Check to see that the pot cover forms a tight seal with the pot’s edges before cooking. Without a good seal, a significant amount of steam will escape, reducing the amount of fresh water vapor available for use.
- 4 Bring the water to a gentle boil, stirring occasionally. You’ll want to bring the water to a gentle boil over a moderate heat. A violent full boil has the potential to pollute the drinking water by splashing it into the drinking glass. The glass might break if it is exposed to too much heat.
- It’s possible that the glass will shift away from the pot’s center and away from its handle if it’s boiling fast and furiously
- If this happens, the water will explode.
- It’s possible that the glass will slide away from the pot’s center and away from its handle if it’s boiling fast and furiously.
- Because of the transformation of water into vapor, it condenses in the air as steam and on the lid’s surface as droplets of water. The droplets then fall to the lowest point (the handle), where they drip directly into the glass. This will most likely take 20 minutes or more
- 6 Allow for a short period of time before drinking the water. Both the glass and the water will be quite hot. Due to the possibility of a little quantity of saltwater remaining in the pot, take care not to spill any saltwater into your glass of freshwater when removing it.
- Taking the glass and new water out of the pot may cause them to cool more quickly
- This is something to consider. Take care not to burn yourself when you remove the glass from the oven. To remove it from the oven, use an oven mitt or a potholder.
- 1 Fill a dish or container halfway with salt water. Keep in mind that you should not fill it up completely. In order to prevent the saltwater from splashing into your freshwater receptacle, you will need to leave some room at the top of the bowl.
- Make certain that your dish or container is completely waterproof. You will lose saltwater before it can generate steam and condense into freshwater, if there is a leak in your system. This procedure will take several hours, so make sure you have enough of sunshine to work with.
- A cup or other small item in the center of the table Take your time with this. This might result in some seawater splashing into your cup if you do it too rapidly! Because of this, the freshwater you gather will get contaminated.
- Make certain that the glass’s rim does not become submerged in water. It is possible that you may need to weight it down with a rock to keep it from rolling about.
- 3 Wrap the bowl tightly in plastic wrap and set aside. Make sure the wrap isn’t too loose or too tight when you’re wearing it. Make certain that the plastic wrap forms a tight seal around the rim of the saltwater bowl before proceeding. The release of steam or freshwater vapor may occur if there are any leaks in the plastic wrap.
- Make sure you choose a strong brand of plastic wrap so that it doesn’t tear.
- In the center of the plastic wrap, place a rock or a weight of some sort. This should be done immediately above the cup or container in the middle of the mixing basin. Fresh water will begin to drop into your cup as a result of the plastic wrap dipping in the middle.
- Make sure the rock or weight isn’t too hefty, or else it will rip the plastic wrap around the rock. Ensure that the cup is positioned correctly in the center of the bowl before proceeding.
- Put the saltwater dish in direct sunshine to keep it fresh. When this happens, the water will heat up and condensation will develop on the plastic wrap. As condensation builds on the plastic wrap, drops of freshwater will drip from the wrap and into the cup.
- Using this method, you will be able to gently gather freshwater. Please be patient as this procedure takes several hours. Take a sip of your freshwater if you’ve accumulated enough in your cup. It is entirely desalinated and completely safe.
- 1 Locate your life raft and any other debris on the ground. Construction of a freshwater generation system from saltwater may be accomplished with the use of pieces of your life raft.
- If you find yourself stuck on a deserted island with no access to fresh water, this approach will come in handy. In the Pacific during World War II, a stranded pilot came up with the idea.
- 2 Locate the gas bottle that was in your survival raft. Open it up and fill it with seawater to begin with. Filter the seawater through a cloth to ensure that it does not include excessive amounts of sand or other contaminants.
- Keep the bottle’s capacity under control. Preventing the water from escaping from its opening will be your goal. Ensure that you return the water to a location where you may start a fire.
- 3 Locate the hose and leak stoppers that were removed from the life raft. Connect one end of the hose to one of the leak stoppers. During the heating process, this will serve as a conduit for new condensed water vapor to escape from the bottle of saltwater.
- Check to see that the hose is not kinked or clogged
- Double-check to ensure a tight seal between hose and leak-stopping devices. This will assist you in preventing any freshwater from spilling out of the hose
- 4 The leak stoppers should be used to seal the top of the gas bottle. Use the leak stoppers on the other end of the hose from where you’ve attached the hose. This will allow water vapor to go from the bottle when it is heated into the hose, where it will be used to convey fresh water.
- Make certain that the seal is tight in order to prevent leaks. In the event that you have any twine or tape on hand, you may use these things to strengthen the seal.
- 5 Construct a sand mound on which to bury the hose. This will help to keep the hose stable when new water is pumped through it to maintain it clean. Keep the hose’s exposed end exposed at all times. This is the point at which fresh water will flow out.
- Neither the gas bottle nor the leak stoppers should be buried. To ensure there are no leaks, you will need to have this exposed at all times while working. In order to ensure proper burial of the hose, make sure it is somewhat straight and devoid of kinks. Placing a pan below the exposed end of the hose will prevent it from bursting. This will gather the fresh water and store it.
- 6 Light a fire and position the gas bottle immediately over the flame. 7 The seawater in the bottle will be boiled as a result of this. With each boiling cycle, steam condenses at the top of the gas bottle and is drawn into the hose as freshwater.
- Because the water collected in the pan will be desalinated, it will be safe to consume.

- It takes a longer length of time and may not be sufficient for producing large quantities of freshwater rapidly, but it is important in actual survival situations.
- Take great care in all you do. Don’t overfill the pot with water. Salt water that has spilled into the middle of the glass is not something you want to consume
You should use caution in what you are undertaking. Keep the pot from becoming overflowing with ingredients. A salty beverage that has splashed into the middle of the glass is not something you want to consume.
About This Article
Summary of the ArticleXTo transform saltwater into drinking water, begin by pouring the saltwater into a bowl and inserting a tiny cup in the center of the bowl of liquid. Then, cover the bowl with plastic wrap and place a rock on top of the plastic wrap over the cup, which will create a dip so that new water may trickle into the cup throughout the cooking process. To complete the process, place the bowl of seawater in direct sunshine. Freshwater will trickle into the cup located in the center of the bowl when the saltwater heats up in the sun and condenses on the plastic wrap, creating condensation droplets.

When compared to the process of converting raw freshwater into potable drinking water, converting saltwater into potable drinking water is far more difficult. Apart from the fact that they are “salty,” brackish water and seawater are replete with live and dead organisms, as well as organic and inorganic particle materials. Every gallon of saltwater includes millions of algae cells, bacteria, and zooplankton, both living and dead, in addition to other organisms. Other elements revealed by microscopic examination include bits of marine plants, mucous from fish and crustaceans, sand, carbonate particles, and crushed crab shells, among other things.
- TEPs are gelatinous colloids that are a significant contributor to fouling (0.4-200 microns).
- TEPs particles can be found in concentrations ranging from 3,000 to 40,000 per milliliter of water on the ocean’s surface.
- Several factors, including water movement, swimming motion of plankton and algae, and electrostatic forces, help to keep all of this suspended materials in suspension (zeta potential).
- Ferric sulfate, or more sophisticated polyelectrolyte flocculation chemicals, are used to agitate raw brackish water before it is treated with a coagulation agent.
The particles can also form heavier agglomerations when exposed to certain coagulants, which settle more quickly as a result of this phenomenon.
If you compare it to the process of converting raw freshwater into drinkable drinking water, the conversion of seawater is far more difficult. Both brackish water and saltwater, aside from being “salty,” include an abundance of live and dead organisms, as well as organic and inorganic particles. Thousands of algae cells, bacteria, and zooplankton exist in every gallon of saltwater, both living and dead. In addition, remnants of marine plants, mucous from fish and crustaceans, sand, carbonate particles, and crushed up crab shells have been discovered through microscopic examination.

5 Foolproof Ways to Make Salt and Seawater Drinkable
Water covers around 71 percent of the Earth’s surface, with freshwater accounting for just about 2.5 percent of total water. Of course, this means that the great majority of the water on the planet is either seawater or saltwater, as the case may be. Consider the fact that saltwater can be turned drinkable while taking this into consideration. The objective of this article is to look into the many methods of making saltwater potable for human consumption. The term “desalination” refers to the process of converting salt water into potable water that is safe for consumption.
Desalination, What is it?
In order to supply freshwater, desalination is the process of removing the salts from saline (salt) water. Desalination is the process of converting saltwater into water appropriate for human consumption, sanitation, or irrigation. Desalination is employed on a large number of seagoing vessels and submarines.
The majority of contemporary interest in this technique is centered on the development of a cost-effective method of providing freshwater for people to drink and use. This method of supplying fresh water for people to drink and consume is growing increasingly popular among the general public.
Can you boil salt water to make it drinkable?
Bringing water to a boil is not sufficient to make it drinkable. To be clear, boiling seawater alone will not enough to render the water drinkable. Desalination is the process of removing salt from water, and it involves more than just boiling salt water to remove the salt. The salt must also be removed from the water before it can be consumed, and boiling water will not permanently remove the salt from the water. It has been determined by the World Health Organization (WHO) that water at 158 degrees Fahrenheit (70 degrees Celsius) will kill 99.999 percent of bacteria, pathogens, protozoa, and viruses in less than one minute.
So how do you make salt water drinkable through desalination?
To make saltwater drinkable, it is necessary to not only disinfect and purify it, but it is also necessary to remove the salt from it. Big amounts of sea or salt water can be fatal due to the pressure it puts on your organs when consumed in large numbers. Your kidneys have no option but to work overtime in order to filter out the salt, not to mention the fact that water with a high salt content will never be able to fully rehydrate you. Separating salt from water may be accomplished with simple equipment, and there are alternative methods that do not require the purchase of expensive equipment and do not require the boiling of the water.
5 easy ways to make sea or saltwater drinkable right from home
Here are five simple methods for making sea or salt water drinkable. The first three methods that I will present will be entertaining and inventive, and they can all be accomplished using common household items. The final two methods involve the use of two separate yet useful gadgets that are readily accessible for purchase.

- Cooking on the stovetop requires a pot, a cover, a burner, and a metal cup. A large bowl, a cup or smaller bowl, a sheet of plastic, and a tiny pebble or rock can be used to make solar desalination solutions. A bowl or container, a plastic sheet, and some rocks are all you need for solar desalination2.
1. Stove Top: Use a pot, lid, stove, and metal cup
- Lid (the pot and lid should be placed together, and the handle of the lid should be located in the middle of the lid)
- A metal or Pyrex cup
Placing a metal cup (or another type of cup that can tolerate high temperatures) in the center of the pot and carefully pouring the saltwater into the pot until it completely surrounds the cup is the first step. Take special care not to get any saltwater into the cup, as this will be where your fresh water will be gathered later on. Afterwards, place a lid with a handle in the center upside down on top of the pot so that, when the water steams (evaporates), the lid will catch the water particles and allow them to trickle down the handle of the lid and into the cup.
- Placing a metal cup (or another form of cup that can resist high temperatures) in the center of the pot and gently pouring the saltwater into the pot until it completely surrounds the cup will be necessary. Take special care not to get any saltwater into the cup, as this will be where your fresh water will be gathered afterwards. Then, upside down on the pot, place a lid with a handle in the center, so that when the water steams (evaporates), the lid will catch the water particles, which will then trickle down the handle of the lid and into the cup below it.
Bring the water to a boil, one cup at a time. It is recommended that you use a low heat setting on your burner so that the water does not splash around and into your cup. Aside from that, you’ll want to allow a reasonable amount of space between the top of your cup and the level of water in the pan. Keep an eye on the water as it starts to boil and condense. It is likely that all of the dissolved salt will have been left behind by the condensed water droplets that form on the lid and drip into your cup.
Once the water level in your cup has reached a suitable level, turn off the heat to allow it to cool completely.
Be extremely careful not to burn yourself (wear oven gloves or some other sort of protective gear) and do not dump the fresh water that you have worked so hard to gather into the sink or toilet. Final step: once the water has cooled, it will be safe to consume!
2.Solar Desalin ation: Use a large bowl, a cup or smaller bowl, a sheet of plastic, and a small pebble or rock
- The following items are required: large basin or container
- Cup or smaller bowl
- Plastic sheet
- Tiny rock or pebble
Solar desalination is the name given to the next cutting-edge method of distilling water. To begin, fill a big bowl or container halfway with saltwater or seawater. Make careful that you do not overfill the large bowl since you will need to place a smaller dish in the saltwater in the middle of the larger bowl later in the process. Then, in the center of the bigger bowl or container, insert an empty smaller bowl or container.
- Caution should be exercised to avoid splashing seawater into the little bowl, which might pollute your drinking water
After that, you’ll take a sheet of plastic wrap and wrap it around the bigger bowl. Make sure that the plastic wrap is securely wrapped around the bowl in order to prevent any of the water vapor from escaping when it evaporates from the saltwater from escaping. You’ll want to use nice, robust plastic wrap rather than the cheap sort that breaks easily or has a difficult time attaching to the food. To finish, add a tiny rock or pebble in the center of the plastic wrap so that it rests precisely on top of your smaller cup or bowl.
Please make certain that your solar desalination system is exposed to direct sunshine so that the solar desalination process may operate without interruptions.
After only a few hours.
it will provide you with clean drinking water!
3.Solar Desalin ation2: Use a bowl or container, a plastic sheet, and small rocks
How to Make Salt or Seawater Drinkable with a Homemade Solar Desalination Plant* The United States Geological Survey (USGS) came up with this proposal for a personal desalination plant. More useful information may be found in their article. Generally speaking, this is termed a “solar still,” since it makes use of solar energy to perform a distillation process, resulting in dew forming on plastic sheeting or something similar.
- Create a hole in the earth
- Placing a basin at the bottom of the pit, which will be used to collect the condensed water, is recommended. A loose plastic sheet should be used to cover the pit (you can use stones or other heavy items to hold the sheet in place over the hole)
- Inspect the plastic sheet to ensure that the lowest portion of it is directly over the bowl. Make sure to leave your water “trap” in place overnight so that water may be collected from it in the morning.
In the dirt, dig a trench. Using a bowl, place a container at the bottom of the pit that will be used to collect the condensed water; Overlap a plastic sheet over the pit (you can use stones or other heavy items to keep it in place) and fill it with dirt. Inspect the plastic sheet to ensure that the lowest portion of it is directly over the bowl; Make sure to leave your water “trap” in place overnight so that you may collect water from it in the morning.

There are several advantages to this Aquamate blowup water purification kit, including the fact that it is packaged in a tiny, portable inflatable package, and the fact that it does not require any power or energy. The desaliniation process is fueled by the sun’s radiation. It does not need to be submerged in water to function, but it does require the presence of saltwater in the device in order to function, similar to the solar desalination method that I discussed above.
We discovered that this product is simple to use and performs admirably; but, it is really sluggish!
- Dimensions: 13 inches by 11 inches by 3.5 inches 38 ounces in weight
I found this device to be incredibly simple (EZ) to use and quite important to have on hand in case you ever find yourself in the situation of having to convert saltwater (or other polluted water) into fresh potable water.
The only bad aspect of the Aquamate water filtration kit is that it is excruciatingly slow to operate.

This machine has shown to be quite beneficial in the distillation and purification of tainted or salt water to produce clean water. When I tested tap water with a Total Dissolved Solids (TDS) tester, the meter indicated 102 parts per million (ppm) (even after being pre-filtered by a Whirlpool Chemical reduction filter). After distilling the water with the Megahome distiller, the meter displayed a reading of 0 parts per million (ppm). It’s a complete and total success. *ppm is an abbreviation for parts per million, and it refers to the concentration of a substance in water.
As of yet, I have discovered very few issues with the gadget, with the exception of the fact that it requires electricity to work, whereas the Aquamate Solar is powered by the sun.
It is possible to turn seawater or saltwater into fresh drinking water by employing one of the five methods described above. Given that the Earth is composed of around 71 percent water, with the majority of that water being salt water, it is vital to understand how to turn salt water into potable water. This procedure can be tedious and uncomfortable to see, but if you are interested in learning more, I recommend that you try one or all of them. We appreciate preparing for crises in the simplest (EZ) manner possible, thus the Aquamate Solar Inflatable Kit and the Megahome Water Distiller are two products we recommend you try.

How To Purify Salt Water for Survival
Desalination may be accomplished on a modest scale with common household materials. If you are in a survival scenario, pot distillers can make the process go more quickly, but you can also achieve desalination with salvaged objects. Because the vast majority of the world’s water is in the form of saltwater, desalination is a concept that has been refined. However, because it is always easier and less expensive to drink fresh water when it is available, desalination is typically only carried out in areas where it is necessary to meet the demands of the population.
There are certain regions with such a limited quantity of fresh water that it is impossible to expand and flourish without generating additional fresh water sources.
Due to the diverse flora and fauna found in the numerous bodies of saltwater found all over the world, the sea salts can be worth far more than you might imagine in some circumstances.
What is the best way to cleanse salt water for survival?
When it comes to determining the most appropriate strategy for you, it is dependent on the scenario in which you find yourself. We’ll go through a couple alternative approaches, as well as some items that you may purchase and keep on hand for convenience.
The Raincoat Method
You can remove salt from water by boiling it, but you’ll need a container to capture the condensation that follows from the process. It is possible to use a raincoat or poncho. In order to accomplish this, you will need to construct a tent out of the poncho or raincoat and place it over the boiling saucepan. Containers should be placed along the borders of the coat to capture the condensation as it flows down the garment. This is an excellent reason to always have an extra poncho on hand.
Bucket and Plastic Method
This is one of those situations when a few things need to be placed back in order to obtain results. It also only works if you have direct sunshine on one side of your body. Supplies a bucket, a jar, a plastic wrap, a little stone Pick up the bucket and put the jar inside of it. To fill the jar, carefully pour the saltwater around it, taking cautious not to pour so much that it floats. Put plastic wrap on top of the jar and add a small stone or weight on top of it so that the surface curls inwards.
This is a time-consuming procedure, but it is effective provided you have the proper supplies and working circumstances.
Remember The Basics
The following essential components are required for the extraction of salt from saltwater. It doesn’t matter what you do to complete the procedure as long as you aren’t employing contaminated materials.
- A method of evaporation
- A container for collecting condensation
- A method of collecting the condensation and returning it to a solid container
As you may have guessed, there are a variety of tools and techniques that can be used to do this, and in a genuine survival crisis, understanding the fundamental acts you must take and continually improving with what you have at your disposal could save your life.
Video Using Plastic Water Bottles
An example of fundamental distillation using anything you can find is shown below.
Pre Made Desalinators
For the purpose of eliminating salt water, any water distiller will suffice. There are also particular emergency desalinators, such as those used in rescue rafts on ships that sail through open sea on a regular basis, and, of course, those luxurious cruise liners that tour the world. Even though they are not intended for the production of moonshine or other alcoholic beverages, stills are good for extracting salt from saltwater. For now, I’m going to show you a few stills from the video, but be sure to check out the previous post on “Best Water Distillers for At-Home Use,” which contains many more choices, all of which are available in a variety of pricing ranges and sizes.
D-STIL Lite(tm)Do It Yourself Emergency Survival Water Distiller
First and foremost, I am astonished at how much water you can get out of this in one hour. According to the description, you will receive 8-10 cups every hour. This implies that only a few hours of operation can provide you with a gallon or more of potable water. That is plenty for two persons who are engaged in some manual labor to get by. If you’re sweating a lot, you can get away with drinking half a gallon of water every day. As a rule of thumb, it is usually preferable to overestimate how much you require.
In addition, two pots will be required for use.
While some may argue that it is excessive to spend for something so little, it is constructed of high-quality stainless steel and is far less expensive than other distillers.
This might also be used on a rocket stove or a camp stove if the situation calls for it. Here is a video that shows how to operate the distiller. The beginning is a little dramatic, but stick with it to see how it plays out in the end.
Seeutek 2 Gallon 8L Water Alcohol Distiller
This particular model of still is reasonably priced and may be utilized for a wide range of distilling tasks. This is the smallest size that they make available. The largest capacity available is 8 gallons, which might be useful for larger projects. The 2 gallon container, on the other hand, is a convenient size since it can be stored easily when not in use and is not particularly bulky.
Emergency Raft Desalinators
These are a bit pricey and primarily useful for desalination, so for the most of us, a good old-fashioned pot will continue to be the most practical option. However, I’d want to share one of them so that you may make the best decision possible for your particular case. If I lived near the ocean and spent a lot of time on a boat, I may choose for one of these instead of something that required me to boil water or utilize the power of the sun to desalinate the water I was drinking. These are a little more difficult to come by, and it’s likely that you’ll have to purchase one through the mail.
The fact that they are only employed on serious boats is a testament to their effectiveness.
Katadyn Survivor 35 Desalinator
However, because they are pricey and primarily useful for desalination, a good old-fashioned pot will continue to be the best option for the vast majority of us. However, I’d want to provide one of them so that you may make the best decision possible for your particular circumstances. A device like this, rather than anything that required me to boil water or use the power of the sun to desalinate water, could be preferable if I lived near an ocean and spent a lot time on a boat. It’s a little more difficult to come by one of them, and you’ll almost certainly have to purchase one from a website.
The fact that they are exclusively employed on serious vessels is a testament to their reliability.
Aquamate Solar Water Purification Inflatable Kit
I believe it is excessive for something that appears to be nothing more than a nice balloon; yet, it is still 10% of the cost of the Katadyn Desalinator, and there is no pumping or substantial maintenance required. This is compact, only takes up a little amount of room, and relies on the power of the sun to function. It is possible that this will take a long time or that it may not function at all depending on the circumstances. On a rainy day, it appears that you would not get much out of this exercise routine.
- Making a large volume of water by boiling saltwater and collecting the condensation is the most efficient method.
- Using a camp stove that accepts white fuel or one-pound propane cylinders is ideal, but you may also use a wood-burning rocket stove or even an open fire if you are careful and set things up properly.
- A pot still can also be used to distill alcohol for use in tinctures, personal consumption, and disinfection applications.
- It is possible that items such as alcohol for drinking and medication would be difficult to come by during long-term SHTF scenarios.
- Consider the scenario in which you have a solar desalinator setup as well as a stove top pot still.
It is good to have a few choices available so that you can readily obtain water if you are in a prolonged scenario. A distiller provides you with some water security and is a fantastic addition to any bug out spot, regardless of whether you are near salt water or fresh water sources.
Taste Of Desalinated Water
For those who dislike the taste of desalinated water and who have a water filter, they can pump the water through it to obtain a more pleasant flavor. Water is made safe to drink once it has been distilled, but the flavor may be a different story. A simple charcoal filter may significantly enhance the flavor. A Brita pitcher is sufficient for removing smells or flavors that have remained. Some people may not see the need to go any farther than making their own alcohol.
Have you ever had to use seawater for survival? Do you have any tips? Is distilling a part of your preps? Is using a desalinater as bad as people say?
The ocean covers 70% of the earth’s surface and contains 96 percent of all the water on the globe, according to the United Nations Environment Programme. The difficulty is that this water is not fit for human consumption. It has an excessive amount of salt in it. Desalination is the process of converting salinity-laden ocean water into potable water for human use. So, with 783 million people lacking access to safe drinking water and more places suffering from severe droughts, might desalination be the solution to these problems?
Water desalination is a major source of clean water in Saudi Arabia, the United Arab Emirates, Kuwait, and Israel, among other places.
These countries also have limited access to groundwater and fresh water sources, making desalination an example of necessity driving invention.
However, the United Nations projects that by 2025, desalination would be used to cover the water demands of 14 percent of the world’s population.
So how does desalination work?
Desalination is the process of converting saltwater water into drinkable fresh water by the use of heat and pressure. Basically, it is the process of converting ocean water into potable fresh water. That seems really great! There are a variety of methods for removing salt from water. Desalination techniques including as reverse osmosis and distillation are the most often used. Reverse osmosis water treatment is a process that pushes water through tiny filters, removing the salt. Distillation on a big scale entails boiling water and collecting the water vapor produced during the process of boiling the water.
So is cost the reason why desalination isn’t used?
Yup. Many countries cannot afford to meet their energy needs because the costs are prohibitively expensive. As a result, it is mostly employed in areas where freshwater, ships, and military boats are in short supply. There are also environmental considerations. Desalination facilities take in salt water directly from the ocean, and the movement of the water from the source to the plant has the potential to kill or injure fish and other tiny ocean life.

The greater the amount of salt that must be removed, the greater the amount of energy required. Plants frequently transform brackish water (think lightly salted potato chips versus normal) to pure water as a result of this. However, brackish water does not occur as frequently as ocean water.
Can it work?
Image courtesy of Flickr user John Wiley It is still prohibitively costly when compared to the use of freshwater sources. Companies, on the other hand, are working on it. Israel began construction on a massive desalination plant in 2005, which will be able to produce enough water to feed half of the country by the end of the year 2015. Yes, the construction of desalination facilities is extremely expensive (the biggest plant in the United States costs $1 billion USD), but it is a lifeline for areas where drought conditions continue and freshwater supplies are restricted or non-existent.
- Following years of severe drought, the state of California is constructing seventeen new desalination facilities.
- In California, desalination is being utilized as a last option to provide water.
- Santa Barbara constructed a desalination plant years ago, but it is just now resuming operations after the original expenses of operating the facility became too expensive.
- Water acquired by desalination is twice as expensive as water received through freshwater sources.
- It is only via the utilization of renewable energy, cost reductions, and environmental safeguards for marine life that desalination can be considered a viable solution to the water shortage problem.
- Saudi Arabia, for example, has pushed for the use of solar energy to power desalination plants in the country.
- Desalination does provide a means for severely water-stressed places to have their own water source, but it does so at a great financial and environmental cost.
- Using a combination of renewable energy and improved technology, desalination might become a more realistic choice.
The fact is that most countries will not use it as their first option. More information may be found at: This teeny-tiny device has the potential to provide clean water to 663 million people.
A more efficient way to turn saltwater into drinking water
Water shortage is a big issue in many parts of the world. According to Amir Barati Farimani, an associate professor of mechanical engineering at the University of Arizona, “it impacts every continent.” According to the United Nations, four billion people live in areas with acute water shortage for at least one month out of every year.” “An estimated half a billion people suffer from acute water shortage throughout the year.” Even while individuals struggle to obtain clean drinking water, there are vast swaths of undrinkable water awaiting them just outside their door.
- As Barati Farimani points out, “seawater covers approximately 71% of the earth’s surface area.” “As a result, this is a really fascinating paradox.” For this reason, Barati Farimani has concentrated his study on water desalination in order to fight the problem.
- The process of desalinating water may be accomplished in a variety of methods, but one of the most successful is membrane desalination.
- The water passes through the pores, but the salt ions are unable to get through, leaving only fresh water on the other side.
- Using a metal-organic framework as a model, Barati Farimani investigates the possibilities of a new form of membrane in his most recent investigation (MOF).
- In addition, Barati Farimani says, “If you look at them, they seem like a honeycomb.” There are a few reasons why the framework is more effective than other approaches.
- Because it is only a few atoms thick, there is very little friction created as the water molecules travel through the pores of the membrane.
- “When you don’t have nearby pores, the molecules are subjected to a tremendous amount of pressure from the wall,” Barati Farimani explains.
Consider the process of pouring water into a funnel to better understand why.
The MOF, on the other hand, contains several neighboring pores that are connected together.
The MOF also has more structural stability than conventional materials, which is an added bonus.
When it comes to creating large numbers of pores, Barati Farimani thinks that graphene and MoS 2 are ineffective.
This enables a larger ratio of pores to surface area to be maintained.
In terms of how rapidly water travels through the MOF and how many ions are rejected, the differences between the MOF and other conventional membranes are significant.
A desalination plant can contain billions of holes, which increases its efficiency by orders of magnitude.
That is our goal: to make water desalination so energy-efficient that it can be used anywhere in the world.
Earlier this year, a paper describing Barati Farimani’s study was published in Nano Letters, a peer-reviewed scientific magazine published monthly by the American Chemical Society.
Besides the realm of academia, Barati Farimani believes that his study will have a positive influence on the lives of those who are affected by it.
“We have a responsibility to supply fresh water to many impoverished people, whether in Africa or elsewhere,” he argues. “In essence, that’s our goal: to make it so energy efficient that we can have water desalination everywhere.”
A Saltwater Desalination Guide
Even though water covers more than seventy percent of the Earth’s surface, only roughly 2.5 percent of that water is designated freshwater (source). Because ocean water contains salt, it is referred to as saline water. Salinated water is not suitable for consumption by humans since the salt might cause the body to become even more dehydrated. The demand for freshwater to support the world’s population is a significant problem to be addressed. Fortunately, it is possible to convert saltwater water into freshwater.
- It is becoming more difficult to get enough fresh water in many desert regions of the world, and this is becoming a serious threat to the local people.
- There is optimism that further research into desalination technology will lead to the development of a solution to the global water scarcity problem.
- Even while ongoing research is contributing to lower desalination prices, the process might still be prohibitively expensive.
- Nature uses solar, or sun, desalination to generate rain, which is a form of desalination.
- One of the earliest kinds of water treatment, distillation is still widely used today to purify salty water, and it is one of the most effective.
- Desalination facilities, which are used to transform salt water into potable water, may now be found in many parts of the world, including the United States.
- Derived from desalinated water, desalinated water is particularly essential in the Middle East, which is projected to utilize over seventy percent of all desalinated water produced worldwide.
- The United States is one of the largest users of desalinated water in the industrialized world, with the majority of its consumption concentrated in Florida and California.
With better technology, there is optimism that desalination will become less expensive, and that it will eventually be able to be employed to address water scarcity concerns on a far larger scale. Learn more about the desalination process and water scarcity by reading the following articles:

Thirsty? How ’bout a cool, refreshing cup of seawater?
It is possible to desalinate tiny volumes of saltwater using a floating solar still, which operates on the principles of evaporation and condensation. Landfall Navigation is to thank for this. No, don’t accept our words at face value! Humans are unable to consume saline water. Salt water, on the other hand, may be converted into freshwater, which is the goal of this portable, inflatable solar still (it even wraps up into a tiny package). The procedure is known as desalination, and it is becoming increasingly popular across the world as a means of providing people with much-needed freshwater.
Freshwater, on the other hand, might be in limited supply in many regions of the country and the world.
In certain regions, salt water (from the ocean, for example) is being converted into potable freshwater for human use.
Perhaps heating some saltwater in a pan, collecting the steam, and condensing it back into water seems like a straightforward process (distillation).
Despite the fact that other ways are available, the existing technical processes must be carried out on a big scale in order to be beneficial to large populations, and the current procedures are expensive to carry out, energy-intensive, and need the use of large-scale facilities.
What makes water saline?
What exactly do we mean when we say “saline water”? Water that is saline has substantial levels of dissolved salts (referred to as “concentrations” in the scientific literature). Specifically, the concentration in this context refers to the amount (by weight) of salt present in the water, which is given in “parts per million” (ppm). If the concentration of dissolved salts in water is 10,000 parts per million (ppm), then dissolved salts account for one percent of the total weight of the water.
- When we talk about “saline water,” what exactly do we mean? A large amount (referred to as “concentrations”) of dissolved salts is present in salinity-treated water. Specifically, the concentration in this example refers to the amount (by weight) of salt present in the water, as measured in “parts per million” (ppm). If the concentration of dissolved salts in water is 10,000 parts per million (ppm), then dissolved salts account for one percent of the water’s total weight. Our saline water specifications are as follows:
By the way, ocean water has a salinity of around 35,000 parts per million (ppm). A view of a reverse osmosis desalination facility in the city of Barcelona, in Spain. Photograph courtesy of James Grellier
The worldwide need for freshwater
In many dry places of the world, the paucity of freshwater resources and the need for new water supplies are already a major problem, and this will only become more so in the future. Surface water supplies such as rivers and lakes are simply unavailable in many dry locations, which means that many arid areas lack freshwater resources. They may only have a limited supply of subsurface water resources, some of which are getting increasingly brackish as a result of the continued extraction of water from aquifers.
Another method: Reverse osmosis
The practice known as “reverse osmosis” is another method of desalinizing saltwater drinking water. In the most fundamental terms, water containing dissolved salt molecules is pushed through a semipermiable membrane (basically a filter), in which the bigger salt molecules are prevented from passing through the membrane holes while the smaller water molecules pass through the membrane holes. Even while reverse osmosis is a highly successful way of desalinating salty water, it is more expensive than alternative alternatives.
Desalination is not modern science
Distillation A popular treatment option around the world, desalination is one of humanity’s oldest types of water purification. It is also one of the most effective methods of water purification available today. Many ancient civilizations employed this method aboard their ships to transform sea water into potable water, which was then distributed to the populace. On ships and in many dry places of the globe, desalination facilities are used to turn seawater into potable water. They are also used in other areas where water has been contaminated by natural and manmade toxins to purify the water.
- This fundamental mechanism in nature is responsible for the water cycle (hydrologic cycle).
- The water vapor ultimately comes into touch with colder air, where it condenses to create dew or rain, depending on the season.
- This is something you can do at home!
- A basin should be placed at the bottom of the pit to capture the water that condenses throughout the cooling process.

Your own personal desalination plant
Remember the photo of a floating solar still at the top of this page? It was a good reminder. If you find yourself in the middle of a desert and in desperate need of a glass of water, you may use the same procedure that powers that equipment. It is possible to achieve this goal using a low-tech technique by building a “solar still,” which uses heat from the sun to operate a distillation process on something like plastic sheeting, causing dew to develop on the surface. This is seen in the diagram to the right.
Due to the surface tension created by the humid air, water droplets form on the bottom of the plastic sheet and fall into a trough, where they can be devoured due to surface tension.
- It is believed that over 30% of the world’s irrigated regions suffer from salt issues, with repair proving to be extremely expensive. As reported by the International Desalination Association, 18,426 desalination plants were operational across the world in June 2015, generating 86.8 million cubic meters of water per day and supplying enough water for 300 million people. This figure has climbed from 78.4 million cubic meters in 2013, representing a 10.71 percent growth in only two years. The Middle East (primarily Saudi Arabia, Kuwait, the United Arab Emirates, Qatar, and Bahrain), which accounts for approximately 70% of global capacity, and North Africa (primarily Libya and Algeria), which accounts for approximately 6% of global capacity, are the two most significant users of desalinated water. The United States is one of the most significant users of desalinated water among developed countries, with particular emphasis on California and sections of Florida in particular. Because of the high expense of desalination, it has not been employed as frequently as it could be.
