17.08.2020

Life can bring many surprises. And not always pleasant. We hope you don't find yourself stranded on a deserted island or in the middle of the African desert with no access to drinking water. But, nevertheless, we advise you to learn how to desalinate sea water using improvised means. Would it come in handy?

The method described below is very popular among fans of life hacks for survival. And for good reason: the process is simple, it does not require much “inventory” and relatively little time. If you start the distillation process at dawn, by noon the sea water will be drinkable.

To desalinate sea water and make it drinkable, you will need:

1. Bucket, bowl or saucepan;
2. Dark container (black color more effectively attracts solar heat and heats up);
3. A glass or a plastic bottle without a throat;
4. Film, plastic bag or cap;
5. Sunshine

Step 1

Place a dark container in a large bowl or bucket.

Step 2

Place a glass or plastic bottle with a cut neck in the middle of the structure.

Step 3

Fill the black container with sea water. Make sure it doesn't hit the glass in the middle.

Step 4

Cover the entire structure with a film or a tight lid. Tightness is everything. If you are using a film, in the center, directly above the glass for desalinated water, put a stone or other weight.

Step 5

Leave your distillation apparatus in the sun and wait. For 8-10 hours under the film in conditions of artificial “heat”, sea water will evaporate, turn into condensate and fall directly into a glass in the form of fresh “precipitation”.

One critical issues modern world is the shortage of drinking water. The issue of its shortage is relevant for almost all countries and continents. The essence of the task is not the extraction or delivery of fresh water, but its production from salt water (https://reactor.space/government/desalination/) .

Relevance of the problem

If the water contains up to one gram of salt per liter, it is already suitable for drinking in limited quantity. However, if this indicator approaches the ratio of ten grams per liter, such a liquid can no longer be drunk. There are also a number of restrictions for drinking water regarding the content of microorganisms and organic components in it. Thus, obtaining a pure liquid is a rather complex multilevel process.

The most popular way to obtain drinking water is desalination. Moreover, this method is relevant not only for regions with an arid climate, but also for Europe and America. Getting fresh water from salt water is the best way to solve the problem.

A variety of fluid deposits with a high salt content can be found in almost any region of the planet. There are no conditions for the reproduction of microorganisms. The brines lie at a relatively large depth, which excludes the occurrence of external pollution by hazardous chemical elements. You can also get fresh water from sea water. In this article, we will look at the most popular ways to solve this problem.

Distillation of water by boiling

This technique has been used since ancient times. There are several types of distillation in use today. The bottom line is to bring the liquid to a boil, and condense the vapor. The result is desalinated water.

Two popular technologies are used to produce a liquid in a significant volume. One of them is called multi-column distillation. The essence of the technology is to bring the liquid to a state of boiling in the first column. The resulting steam is used to transfer heat to the rest of the columns. This technique is effective. With its help, you can get fresh water on an industrial scale. However, this technology is very energy intensive. Therefore, in our time it is used quite rarely.

Flash distillation has been found to be more efficient. The essence of the technology is the evaporation of salty liquid in special chambers. In them, the pressure indicator is gradually reduced. Accordingly, to obtain water vapor, a lower temperature indicator is needed. That is why this technology is more efficient.

There are two more methods of distillation: membrane and compression. They arose as a result of the modernization of the first two technologies. Membrane distillation is based on the use of a hydrophobic type membrane that acts as a cooling coil. It retains water while letting steam through. Compressive distillation is based on the use of compressed (superheated) steam in the first column.

All of these technologies have the same drawback. They are too energy intensive. It takes four hundred and twenty kilojoules to heat a liquid from zero to one hundred degrees. And to change the state of water from liquid to gaseous, it will already take two thousand two hundred and sixty kilojoules. Equipment operating on the principle of the considered technologies consumes from three and a half or more kilowatts per hour per cubic meter of the resulting desalinated liquid.

Distillation by the sun

In southern countries, solar energy is used to carry out the distillation process. This allows you to significantly reduce the cost of desalination of salt water. To perform the distillation process, you can use solar panels or directly thermal energy from the Sun. The simplest in technical terms is the technology based on evaporators. The latter are special prisms made of glass or plastic into which salty liquid is poured.

As a result, solar energy raises the temperature of the water. The liquid begins to evaporate and precipitates in the form of condensate on the walls. The drops emerging from the steam flow into special receivers. As you can see, the technology is very simple. Of its minuses, it is worth highlighting the low rate of efficiency. It does not exceed fifty percent. Therefore, this technology is used only in poor regions. With its help, it is possible to provide fresh water at best to a small village.

Many engineers continue to work on modernizing the considered technology. Their main goal is to increase the output of such systems. For example, the use of capillary films can significantly improve the performance of solar distillers.

It should be noted that systems powered by alternative energy sources are not the main tool in obtaining fresh water. Although, their use does not require significant costs for the distillation process.

Other technical solutions can be used to remove salts from the liquid. A fairly popular method of water purification is electrodialysis. To implement the method, a pair of membranes is used. One of them is necessary for the passage of cations, and the second is used exclusively for anions. Particles are distributed over the membranes under the influence of direct current. Such a solution is often implemented in conjunction with solar and wind generators.

Reverse osmosis

Water desalination technologies are constantly improving. Reverse osmosis is becoming more and more popular these days. The bottom line is the use of a semi-permeable membrane. A saline liquid passes through it. As a result, particles of salt impurities remain on the side where the pressure indicator is excessive.

The reverse osmosis method is the most economical. Especially if it is used for desalination of water with non-critical salt content. In this case, one kilowatt-hour of energy can be enough to produce one cubic meter of water. Therefore, reverse osmosis technology is considered the most promising.

Results

Each water desalination method has its own characteristics. To produce fresh water on an industrial scale, it is necessary to select the most economical and efficient option. The reverse osmosis method is by far the most effective.

People have long figured out how to desalinate sea water in the absence of access to drinkable water, because drinking moisture is the basis for the existence of a living organism.

Today get out sea water desalinated can be done in different ways and under different conditions - industrial, domestic and even extreme. Such skills will quench the pangs of thirst when fresh drinking water is out of reach for some reason.

Existing water desalination methods

In some regions of the planet, the shortage of fresh water is most noticeable - usually these are arid landscapes. In such an area, industrial desalination is used.

At home, the production of desalinated water from salt water is forced by difficult living conditions, temporary or permanent, when the population is experiencing an acute shortage of drinkable moisture.

Skills how to do drinking water, having only the sea, more than once saved lives in conditions of natural disasters, fishermen lost in the sea, as well as extreme travelers.

Methods of industrial desalination - chemical with the help of reagents, industrial distillation in a distiller, ionic with the help of a plant and an ion exchanger, reverse osmosis through membrane filters, electrodialysis and industrial freezing;
Home desalination methods - distillation and partial freezing;
Extreme desalination methods - collection of condensate using fire or sun, as well as melting fresh ice.

Methods for desalination on an industrial scale are not our topic, but we will describe in more detail how to get moisture quite suitable for drinking at home or in nature - they can be useful.

Water desalination at home

At home there is always a source of fire or heat, utensils and appliances that will be useful for turning sea water into desalted distillate, in extreme cases there is a freezer.

Best of all, it distills sea water into a distillate of a household moonshine if there is a source of fire, but it will also work made on hastily its counterpart. The task is this:

cause sea water to evaporate abundantly from heating;
drain the collected condensate;
cooling drops of steam, collect them in a separate container.

As a substitute for moonshine serpentine, any dishes that can be put on fire are suitable. Sea liquid is poured into it, then the vessel is covered with a lid with a hole into which a steam-removing tube is inserted. It remains to put a plastic hose on the tube, lower its tip into the container where fresh water will accumulate, and cover it with a wet rag so that the steam cools faster.

Sometimes during a disaster in the surviving housing there is no water, no gas, no electricity, but there is some kind of undrinkable water. In this case, there are 2 options not to die of thirst.

Option number 1.

The initial liquid is poured into a plastic bottle.
Its level should be such that it does not reach the neck of the bottle if it is laid flat.
The neck of the bottle with the original liquid is connected to the neck of the empty bottle with adhesive tape.
The design is placed flat in the warmest place that is found in the house - for example, a battery or a sun-drenched window sill.
Any object is placed under an empty bottle so that it is slightly higher than a bottle of liquid.
Soon, drops of evaporated condensate will accumulate at the top of the empty bottle and flow down.
It remains to cut the adhesive tape and separate the containers - the empty water will be drinkable.

Option number 2.

We need a small basin with high walls.
A small container is placed in the center (a simple glass will do).
Water for desalination is poured into the basin, its level should be below the level of the glass.
Polyethylene or cellophane film is stretched on top of the pelvis.
A small weight is placed on the film, directly above the glass.
The design moves closer to the heat source.
Soon, drops of evaporated condensate will accumulate on the film and flow down.

It remains to remove the cellophane from the basin - the glass will contain drinkable water.

Note! These methods work remarkably well in natural conditions.

The third option to get drinking water is partial freezing in the freezer.

Pour sea water into a wide container.
Place in the freezer.
Periodically monitor the freezing process.
As soon as a thin layer of ice appears, carefully collect it, this will be fresh water.
Remove each time only a small layer of ice - its crystals contain almost no salt.

Note! Completely frozen sea water will produce salty ice.

Water desalination under extreme conditions

To get hold of drinking water, having an abundance of sea water, in an extreme environment, when kilometers to a natural fresh water source, is a matter of survival.

The fastest option is to build a primitive distiller on the fire.

To do this, a container filled with sea water is placed on the fire and covered with a lid on top.
It is advisable to make a hole in the lid and insert a steam outlet tube into it.
If there is no hole and there is nothing to pierce it with, then the tube is simply clamped with a lid.
The other end of the tube, through which drops of condensate will flow, must be lowered into a clean bowl.
To speed up the escape of steam, the tube is covered with a wet cloth or constantly poured with cold sea water.
In the absence of a lid, a “roof” is constructed from the dishes at an angle of metal, a clean vessel is substituted to the lowest edge, where the distillate will drain.

If it happens in the summer heat, there is a very simple option to desalinate the water, but in time it will not be as fast as with the help of fire. To do this, you need only one container, a film and a dug hole.

You need to dig a hole a little deeper than the height of your container.
The bottom of the pit is abundantly watered with sea water.
An empty container is placed in the center of the recess.
The pit is completely covered with a film, and its edges are tightly fixed with sand, pebbles, earth.
A load is placed on the center of the film, directly above the vessel - a pebble, a stick, a lump of soil or a handful of sand, so that the coating becomes concave.
Water, evaporating, will begin to settle on the roof of the film and flow down the slope straight into the placed container.
In the heat, in a couple of hours, enough water will collect in the vessel to get drunk.

Note! The condensate is completely devoid of salts, so in order to quickly quench your thirst, experienced thrill-seekers advise adding a little sea water.

Another method of desalination is freezing, suitable for harsh winter conditions. Its algorithm is similar to home freezing, only street frost will act as a freezer here. You need to scoop up sea water and wait for ice crystals to appear on the surface - they will taste fresh, and you can drink such water.

Water- the source of life for all living things, but you need to distinguish which water is useful and which is not. Approximately 99% of all the waters of the earth is the water of the oceans and seas, that is, salt water, is unsuitable for consumption. Many people in the world need living, fresh water, and today we will tell you how to get fresh water from salt water.

How to make fresh sea water at home?

Fresh water differs from salt water in the amount of salt and other chemical elements. The most popular way is to separate salts from water by distillation.
This method consists in heating water to the boiling point, and collecting vapors in the form of condensate. This method is well described in the article - .

There is also another way, the so-called - desalination. It consists in the fact that salt water is passed through a membrane that can only pass pure water without salt components. But this type of purification is not very effective, since the membrane passes a very small amount of water over a long period of time.

Issues discussed in the material:

Why is there a need for seawater desalination?
What are the methods of desalination of sea water
How to desalinate sea water at home
What problems are inherent in the process of seawater desalination

Purification and desalination of sea water is an industrial process, as a result of which salts are removed from it and a product suitable for domestic use and consumption is obtained. Our article will tell about the methods and technologies of seawater desalination.

60% of the earth's surface consists of territories where there are either no sources of fresh water at all, or there are, but a very small amount. Since there are few freshwater reservoirs in many arid areas, there are problems with watering the soil. They could be solved thanks to the possibility of using desalinated sea water for these purposes. There are significant reserves of such water on Earth, but due to the high salt content, it cannot be used for economic purposes.

To grow crops, it is necessary to water them with water with a very low salt content. If plants receive more than 0.25% salts with moisture, they simply will not grow. Also, the presence of alkalis in the water will adversely affect them. Many states, including Russia, are looking for ways to desalinate salty water sources, which would help to cope with drought problems in areas located near the sea.

In countries with a well-developed industry, there is an increasingly acute shortage of fresh water reserves. In particular, this applies to the USA and Japan, where the required for industry, Agriculture and household needs, the volumes of water have long exceeded the available ones.

The amount of fresh water does not meet the needs in developed countries with low level rainfall, such as Israel and Kuwait.

Russia occupies the first place in the world in terms of terrestrial freshwater resources. Baikal alone is enough to satisfy the current need of the Russian population and industry for fresh water. This lake is so deep that if you direct the flows of all the rivers of the globe into its basin, then it will fill up for almost 300 days.

but most of Russia's water resources are concentrated in practically uninhabited and undeveloped regions of Siberia, the North and Far East. To highly developed central and southern regions with high level industry, agriculture and population density account for only 20% of freshwater reserves.

Certain countries Central Asia(Turkmenistan, Kazakhstan), as well as the Caucasus, Donbass and the southeastern part of the Russian Federation, have huge mineral and raw material resources, but they do not have freshwater sources.

In Russia, there are a large number of underground sources, the mineralization level of which ranges from 1 to 35 g/l. They cannot be used for the needs of the population, as they contain a large amount of salts, but after desalination they can be used quite well.

In the process of sea water desalination important parameter is its salinity, which refers to the mass of dry salts in grams per 1 kg of substance. The amount of salts per unit volume of liquid can vary significantly depending on the sea. For example, the Black, Caspian and Azov Seas are characterized as slightly saline. The average salinity of the World Ocean is 35g/kg.

In addition to table salt (NaCl), sea water also contains a number of other chemical elements, mainly in the form of ions that can be obtained from it on an industrial scale: K +, Mg2 +, Ca2 +, Sr2 +, Br-, F-, H3BO3. In total, about 50 chemical elements in various concentrations have been found in the subsoil of the sea, including lithium (Li), rubidium (Rb), phosphorus (P), iodine (J), iron (Fe), zinc (Zn) and molybdenum (Mo).

Marine water resources contain more than 50 chemical elements. The concentration of each of them is extremely small, but their total mass determines the salinity of the liquid. Only water containing no more than 0.001 g / ml of salts can be suitable for food. In order to achieve such a concentration, various seawater desalination technologies are used. Specialists are trying to develop desalination systems that would consume little energy, but at the same time purify water as much as possible for use by the population.

Today, the following methods of seawater desalination are used: distillation, reverse osmosis, ionization and electrodialysis.

In the southern regions, solar distillers are actively used, in which sea water is heated and evaporated. There is also an opposite method, in which salt water is frozen and then fresh water is separated from it, since it freezes faster.

A sea water maker is a device that can remove salts dissolved in water from water. After the purification procedure, water is obtained, which can be used not only for household needs, but also for drinking. The design of the device is distinguished by convenience and practicality in operation.

However, desalinated water is not clean at the same time, because other components are also preserved in it, the density of which determines the area of its application. So, on ships, different types of water reserves are required:

drinking, which is used only for cooking and drinking;
water for personal hygiene and deck washing;
water for steam generators, or feed water;
technical water, which is used as a coolant for engines;
distilled water.

To obtain all these types, different ship distillers are used.

Desalination technologies include the following:

Distillation, in which the desalinator heats and evaporates sea water. The resulting steam is "caught" and brought to the required temperature.
Filtration, in which the device works on the principle of reverse osmosis. Salt water is purified without going from one state to another. The operation of such an apparatus is based on bringing the concentration of dissolved impurities to the optimum. Very high pressure allows you to "squeeze out" excess salt particles.

In the Israeli city of Hadera, there is the largest distiller on the planet. This unit is commensurate in size with the whole plant. Every year it desalinates about thirty-three billion gallons of sea water. The distiller works on the principle of reverse osmosis, as a result of which the Mediterranean waters are not subjected to heat treatment.

The installation is completely hermetic, it creates the effect of a greenhouse, while no leakage of fumes to the outside is allowed. As a result, the net water residue is retained in a larger volume. At the end, the cork is unscrewed, and the purified liquid is drained into a container.

Similar devices are used in navy. They use the heat of the liquid, which serves to cool the main and auxiliary diesels. Purified water, heated to 60 °C, enters at the inlet through the pipes of the heating battery. When leaving the liquid, the temperature of the liquid drops to about 10 °C.

Vacuum maker produces about 800 liters of distilled water per hour. It can meet all your fresh water needs without wasting fuel energy, and full automation saves maintenance costs. Since the evaporation temperature is quite low, the water maker can operate for six to twelve months without requiring cleaning.

It is known that the population of Israel suffers from a serious shortage of drinking supplies. The operation of the apparatus described above makes it possible to cover almost two-thirds of the water demand of the whole country.

Today, a variety of equipment is used to desalinate seawater, including unique solar-powered desalination plants. Water is poured into them, which, under the influence of solar heat, turns into steam, condenses on the walls of the case and then settles in the lower part of the device.

To date, two methods of desalination are widely used in industry: membrane (mechanical) and thermal (distillation). In the first case, reverse osmosis technology is used. Sea water is passed through semi-impermeable membranes under a pressure significantly exceeding the pressure difference between fresh and sea water (for the latter it is 25-50 atm.).

The microscopic pores of the filters freely pass only small water molecules, retaining larger ions of salt and other impurities. The material for such membranes is polyamide or cellulose acetate, they are produced in the form of hollow fibers or rolls.

The method of deep reverse osmosis water desalination has a number of advantages compared to other methods. Firstly, the devices are simple and compact, and secondly, they do not require large amounts of energy. In addition, the reverse osmosis system is controlled in semi-automatic and automatic modes.

However, this method also has its drawbacks. The quality of cleaning here depends on how effective the pre-treatment was. In addition, the resulting drinking water still contains a fairly large amount of salt (500 mg/m3 of total salt concentration). Also, this method requires increased operating costs, since the regular purchase of associated chemicals and the change of membrane filters are necessary.

Wonthaggi Desalination Plant is the world's largest membrane filter desalination plant located in Melbourne. It is capable of processing 440 thousand cubic meters of water per day. In the Israeli city of Ashkelon, there is a plant where water is purified from salts by reverse osmosis. It processes 330 thousand cubic meters of water per day.

The essence of the thermal method (distillation) is that liquid is boiled at the seawater desalination station, and the resulting steam is accumulated and condensed. This forms a distillate - fresh water. You can also boil water without bringing it to a boil. In this case, it is heated at a higher pressure than in the evaporation chamber. The heat of the water itself is used to form steam. At the same time, it is cooled to the saturation temperature of the remaining brine. The disadvantages of this method are the cost, high energy intensity, and the presence of an external source of steam. However, it is he who gives the largest volume of fresh water per unit of time. For example, the Shoaiba 3 plant ( Saudi Arabia) produces up to 880 thousand cubic meters of fresh water per day using the distillation method.

The two methods can be compared in several key ways:

Parameters	Reverse osmosis	thermal method
Physico-chemical principle	Membrane diffusion	Thermal evaporation and condensation
Energy Consumption (Including the consumption of auxiliary devices)	Electricity: 3.5-4.5 kWh/m3	Electricity: 2.5-5 kWh/m3, thermal 40-120 kWh/m3

total cost
Level of production automation
Ability to change the composition of sea water		medium-high
Maintenance Requirements
Scaling Potential		Medium-low
Space Requirements
Most Needed Improvements	Improvement of water pre-treatment, improvement of membrane properties	Cheaper materials and heat transfer methods

Difficulties with fresh water supply arose in Crimea after the well-known events in 2014. Then Ukraine blocked the canal through which fresh water was supplied to the peninsula, resulting in a shortage of technical and drinking water reserves.

There is information about the planned installation of a desalination system in Kerch, which will produce about 50 tons of water per hour. Salt-free water resources will be used mainly for technical needs: feeding heating networks and steam boilers. This will help reduce the burden on the public water supply.

Water purification at this plant will take place in several stages. For clarification, it is supposed to use a combined membrane technology, for purification from salts - a reverse osmosis method, for polishing softening - an ion-exchange method.

The system will work in automatic mode, only one operator is needed to control the process.

Today, the profitability of irrigating crops with desalinated sea water is a big question: unfortunately, existing technologies do not allow obtaining both high-quality and cheap fresh water from salt water. But different countries of the world are constantly working in this direction, because ecological problems desalination of sea water concerns all mankind and requires permission.

Scientists have high hopes for the use of atomic energy to clean water resources, which would make desalination technologies much cheaper.

Do-it-yourself seawater desalination at home and in extreme conditions

If you need to purify sea water from salts during a hike, a home-made distiller is best suited for this, similar in design to well-known distillation apparatus.

The essence of the process in a conventional desalination plant is as follows: the salty liquid is heated to a boil, then the resulting steam is accumulated in a container and cooled. After the procedure, chilled droplets of water, purified from salt impurities, settle on the walls of the chamber.

Salts stand out from the mixture because the boiling point of a brine solution is slightly higher than that of pure water. Therefore, the fresh component evaporates faster and settles into the collection container.

To desalinate sea water in field conditions, you will need:

first of all - the water itself, which is always in abundance on the coast of the sea or a salt lake;
a kettle or kettle as a container for heating;
an aluminum tube, which should be prepared before the start of the trip;
a deep hole dug in the sand: it will serve as a cooling device;
another container (glass bottle, stainless steel jar, etc.), where water purified from impurities will be collected.

On the shore of a lake or sea, you should dig a hole up to a meter deep, place a container (bottle) in it at a slight angle, into the neck of which you need to insert a tube.

Prepare a rubber gasket in advance: with its help, you will securely seal the junction of the aluminum tube with the neck of the bottle.

Then the structure should be covered with sand in such a way that only the upper part of the neck with the inserted tube remains open. The end of the tube will need to be placed over a kettle or open kettle of sea water. In this case, the fire is bred at a small distance from the bottle with the tube.

After the fire flares up, the water in the container will warm up and begin to boil, and the steam will gradually spread through the tube into a bottle buried in the sand, where it will settle like condensate. Gradually, up to 200-300 grams of pure fresh liquid is formed at the bottom of the container.

by the most in a simple way to purify water from salt at home is considered to be the use of a system consisting of a number of filters connected in a certain sequence. But even a complex multi-stage combination cannot remove absolutely all harmful impurities from the water. Therefore, long-known home desalination methods are very popular among the people.

For example, water is poured into a bottle and placed in a freezer, where after a while the pure component freezes. The part that does not freeze just contains all the harmful impurities, so it is drained. The frozen water residue, when it melts at room temperature, can be used for drinking and other needs.

There are two more ways to purify salt from water that can be easily implemented at home. The first is long boiling, as a result of which salt settles on the walls in the form of scale. The second is activated carbon filtration. In this case, the amount of material used will depend on the salt concentration.

Today, of all desalination methods, reverse osmosis technology is the most in demand. But its use requires high costs for the production and operation of membranes, as well as significant energy capacities. In addition, after desalination in this way, a highly concentrated salt solution remains, which is returned to the sea or ocean, which increases the salinity of water resources. Because of this, the purification process becomes even more complicated, and the cost of seawater desalination only increases every year.

In addition, only 1/3 of the world's freshwater resources are in the soil (2/3 are frozen in snow covers and glaciers). And they are used by man so quickly that nature does not have time to make up for the lost.

In this regard, the scarcity of fresh water is increasing on a global scale.

Experts predict that by 2030 more than two billion people will experience water shortages. This problem is exacerbated by the fact that each country uses different volumes of fresh water.

For example, an American consumes on average about 400 liters per day, while a resident of an underdeveloped country consumes only 19 liters. Half of the world's population does not have running water at all in their homes. All this will one day lead people to pay special attention to the oceans as sources of water.

The main challenge in seawater desalination is to minimize energy and equipment costs. This is especially important because a country that needs more purified water must also withstand economic competition with countries that have cheaper and more abundant freshwater sources.

According to the results of design development, it turns out that only for a small number of consumers it will be cheaper to transport water from a natural reservoir over a distance of 400-500 km than to desalinate it. Estimating underground reserves of varying degrees of salinity in arid regions, we can conclude that desalination is the only economically viable way of water supply for them, given their remoteness from freshwater sources of natural origin.

The desalination methods used today can be productively used to return used water resources to nature without worsening the condition of fresh water bodies.
