Why does well water foam?

Why yellow water is dangerous

A change in the color of the water clearly signals a deterioration in its quality. To understand whether it is suitable for consumption and everyday use, whether it will harm your health, it is necessary to conduct a laboratory analysis.

And even if he shows that everything is in order with a high-quality composition, it is still better to try to get rid of yellowness, because you are unlikely to like the look of unwashed linen or unsightly stains on plumbing.

An examination will show why the water in the well is yellow, and you will know what it threatens you with and how to deal with the problem. You should not delay this, especially if the analysis reveals the presence of iron or organics.

So:

• Water with a high concentration of iron is harmful to health. Monovalent iron is unstable, getting into the body, it reacts with chemicals necessary for normal life.
  Together they form completely different compounds, which can be dangerous. Therefore, such water cannot be drunk and used for cooking and drinks.
• Also, do not wash your face with rusty water, take a bath or shower, as iron can cause dermatitis and allergic reactions. Moreover, it can negatively affect the composition of the blood.

Swimming in such water is not recommended.

The presence of organic substances formed during the decay of organic matter that has entered the water not only changes the color and smell of water, but also makes it bacteriologically dangerous (see Disinfection of water in a well - when and how to do it). With its use, indigestion, intestinal infections and other more serious problems, up to poisoning, are possible.

What about the new wells?

During the digging of the well, initially the water in it will be cloudy. The reason for this is the layer-by-layer removal of soil and the scooping of liquid from the mine. In the course of the work performed, particles of soil and clay are at the bottom. That is why you should not wait immediately for clean water. It is necessary to give time for the liquid to settle.

Springs on clay soils settle for the longest time. As practice shows, the owners of these wells can wait months for water clarification.Moisture should not only settle, but also flush the channels into the mine, after which the turbidity will gradually disappear. Only after this, experts recommend starting a gradual pumping of the well in order to completely get rid of the trouble.

The presence of turbidity in the water after cleaning the well is a natural phenomenon. Perhaps not enough time has passed. It is necessary to wait for the water to settle. However, if this did not happen, it is necessary to look for reasons. First of all, they check:

• Seam tightness.
• The presence of a source of pollution.
• presence of dissolved iron.
• Water stagnation.

How to purify lime water at home?

Test "strips" are suitable only for an approximate assessment of individual types of pollution. You should be skeptical about the tricks of unscrupulous sellers. They use electrolysis or coagulation to show flakes that "confirm" an excessive amount of impurities.

To accurately determine the problem, a preliminary laboratory analysis is done. Specialized enterprises offer such services inexpensively and quickly fulfill standard requests. The sample is collected in a clean container, handed over no later than 48 hours later. This helps to minimize the influence of oxidative and biological processes. The results obtained are used to select the appropriate equipment.

At the next stage, the actual needs of an apartment, cottage, or other property are determined. If necessary, make the division of the system into the preparation of technical and drinking water.

Equipment with high performance is installed in the highway. Mesh structures (mud collectors) retain particles with sizes of 20-120 microns. Choose models created for the appropriate temperature range.In urban conditions, the standard equipment is supplemented with a pressure gauge, regulator and safety valve. This is necessary to protect against a sharp increase in pressure in the central water supply.

Modern lime filters in this category are equipped with a transparent storage part to simplify visual control. Through a manual or solenoid valve, the device is connected to the domestic sewer. A timer is used for automatic control. It must be remembered that in addition to regular, a more thorough flushing with disassembly is occasionally performed.

Particles from 20 to 50 microns are retained by backfill filters at home. In this case, it is easier to ensure high performance. Use steel and composite tanks with a built-in pipe and intake device. For cleaning, reverse flow direction is used. The automation unit switches the modes, which, together with the valves, is fixed on the head.

Cartridges with certain fillers are used to separate particles from 5 microns or more. The only drawback of such products is the inability to reuse. The need for frequent replacement with significant contamination of the source liquid increases the operating costs of this method of lime water purification at home in the country or in a country house.

Cleaning with polyphosphates and electromagnets

Coagulants and chemical reagents are rarely used in domestic conditions in order to exclude secondary clogging with harmful impurities. However, there is an exception that is useful for protecting against scale. These are polyphosphates. They dissolve in water, form a shell on calcium and other small particles.Such an obstacle blocks the process of adhesion into large formations.

Polyphosphates are harmless to health, but can cause an allergic reaction. They are used exclusively for the preparation of technical water. General processing is performed using ion exchange techniques. The same kit as for the backfill filter will do. It is supplemented with a container with a recovery solution and connecting tubes.

Relatively new is electromagnetic processing. The principle itself has been known for decades. But only today the technology has been developed well enough to provide reliable protection at a reasonable cost. In this option, the composition of water from a well or well does not change, but microparticles of calcium salts are transformed. As with the use of polyphosphate softeners, scale growth is blocked.

Equipment selection

The separation of relatively large solid impurities is a standard procedure for the first stage of water treatment. Instead of mesh, you can use electromagnetic filters for lime water from a well. They, like cartridges and fillings, create a voluminous working field. Narrow channels of complex shape effectively trap small contaminants. With a certain increase in the pressure difference between inlet and outlet, automatic cleaning is activated.

Electromagnetic transducers perform their functions fully without deteriorating the parameters of the source liquid. They are compact! For installation at home and superstructure, professional skills are not needed. When choosing equipment, you will not need a separate room with good insulation, as for an ion exchange plant.

Human factor

Very often cloudy water is present in the wells of new houses.But in this case, the reason lies in the fact that no one uses the well. That is, the water in the building must be constantly updated. And if this does not happen, it stagnates, becomes cloudy and blooms.

Another cause of cloudy water can be organic substances that enter it through a loosely closed lid. Such substances include various debris in the form of grass, leaves, tree branches or small animals. After spending some time in the water, they begin to decompose, which leads to the development of pathogenic bacteria.

As a result, an unpleasant smell emanates from the well, which is often confused with sewer. This smell is the result of the release of poisonous hydrogen sulfide gas. At the same time, the water darkens, acquiring an unpleasant aftertaste.

The cause of cloudy fluid may be an incorrectly installed pump

Given that the operating pump vibrates, it is very important during installation to accurately calculate the depth of its lowering. Otherwise, it will begin to raise silt from the bottom, sucking it through the inlet. It also happens that the liquid in the structure becomes cloudy after cleaning the mine

And this can discourage many owners of private houses. After all, the cleaning process is very laborious, and when you find muddy water in a seemingly sterile well, you give up. However, don't get upset

It also happens that the liquid in the structure becomes cloudy after cleaning the mine. And this can discourage many owners of private houses. After all, the cleaning process is very laborious, and when you find muddy water in a seemingly sterile well, you give up. However, you should not get upset in vain.

How do I clean the well?

Just after cleaning in the well, there was a violation of already established processes. After all, dirt is heavier than water, and therefore it sinks to the bottom. And after she was aroused, she will “muddy” the water for some more time.

Well cleaning

So, let's take a closer look at how to get rid of the smell of water in the well. At least once a year it is necessary to carry out preventive cleaning of water. Thanks to this, it will be possible to avoid many problems with water supply, and therefore with health. If this is not done, then mucus may appear quite quickly. It is she who is the expanse for the rapid reproduction of harmful bacteria. In addition, debris and silt can settle at the bottom of the well. As a result, the quality of well water deteriorates.

The procedure consists of several stages:

1. Disinfection with special preparations. It is used strictly with the instructions in the attached instructions.
2. The water is pumped out with a pump.
3. The well is cleaned from various deposits using a mechanical method, that is, with your own hands.

Why does water foam?

The foam in the aquarium is created by the accumulation of organic compounds (often these are proteins and amino acids) in water. Organics make water fatter, and strong filtration, aeration and other phenomena that contribute to the agitation of water whip up protein substances, as a result of which foaminess appears. In stagnant water, foam does not form.

When starting the aquarium for the first time, foam bubbles also appear due to the preparation of biological filters, in which case it is enough just to wait and the water itself will become crystal clear.

It is worth noting that contributes more to the formation of foam on the surface of the aquarium than hard . In most cases, foam does not pose any threat, especially if it does not appear. In case of detecting odors, pronounced turbidity of the water, a change in its color, or dead fish, it is worthwhile to quickly find a weak spot in the reservoir.

Why is there yellow water in the well?

The water from the well is natural, without chemical impurities, usually having a specific taste. A person gradually gets used to it, but the unexpected yellow color usually causes panic and persistent disgust. However, before you start to deal with the problem, you need to understand the reasons for the color change.

Natural factors include:

• Intensive precipitation infiltrated into the aquifer;
• Seasonal increase in the concentration of humic acid salts in the soil;
• Decreasing/increasing the level of occurrence of the groundwater layer;
• Flood.

Sometimes rusty liquid is provoked by the human factor:

• Careless operation of the system, leading to pollution;
• Lack of a canopy, as a result of which dust, dirt, leaves get into the well;
• Clogged filter located at the mouth of the pipe.

To restore the original transparent color, you will have to disassemble the system and, possibly, even involve special equipment. But after eliminating all the shortcomings, the red liquid may never appear again.

Main reasons

Scenery

You can understand what exactly the decorations are to blame for the foaminess of the water by the color of the foam (it can be of any color, but gray and milky colors are most common). To solve the decoration problem:

1. Remove the unfortunate object from the water
2. Start the filter and aerator.

In order to prevent a problem, it is recommended to introduce decorative elements only after checking, after pouring them with running water.Purchase exclusively high-quality goods in specialized stores, and avoid parts covered with paint layers.

If paint peeling or microcracks are noticeable on the parts, then it is forbidden to place them in a container.

Sometimes dead inhabitants of the aquarium can get stuck in the decorations and this can also cause foam to appear.

Filters

Another common cause of foam formation is a problem with. It may have weak or vice versa strong power, or be contaminated. Filter problems can be identified by the presence of foam, organic residues in the water, and blue-green or red algae. The solution will be:

1. Acquisition of a high-quality filter of optimal power if it does not cope with its task.
2. Disassembling and washing the filter if it is dirty.

To prevent trouble, it is necessary to choose a filter suitable for the aquarium, monitor it properly and take preventive measures.

Chemicals and medicines for fish

They tend to react with organic matter, creating a foamy "cloud" by which the roots of the problem can be identified. To get rid of negative effects, you need:

1. Minimize the amount of chemical fertilizers and drugs.
2. Use a mechanical filter, pump or aerator.

To prevent excess foam, you can initially conduct experiments with drugs in a separate container with water and predict approximate scenarios for the development of events, and at the same time determine the optimal dose of drugs. Usually all the necessary information is given in the instructions, which must be clearly followed.

plant dissolution

As the vegetative mass of plants grows, volatile substances are released, which are easily identified by smell, for example: hydrogen sulfide, ammonia, swamp, rotting, fermentation. In case of soil damage by toxic substances, it is necessary:

1. Extract and carefully it.
2. Dry in the oven.

Usually, clearing accumulated debris from the ground surface will nip the problem in the bud.

Irregular cleaning

You can understand that an infrequent change of water is behind foaming not only by the presence of foam, but also by debris, waste, scales, uneaten food, and so on. All this clogs the water and dissolves in it. In addition, cyanobacteria rapidly growing in dirty water begin to bloom and create additional cloudiness. In order to correct the situation and prevent problems with reservoir contamination, it is enough to renew 10-20% of the water every week.

Excessively frequent fluid changes

Do not go to the other extreme - renew the water too often

, as this is fraught with cloudy water and the death of beneficial bacteria that are unable to recover. In many ways, the biological filtration of water depends on them. The recipe for correcting and preventing the problem is the same as in the previous paragraph - timely portioned water updates.

Quality and quantity of food

An abundance of food can also create a "cloud" of foam. Its excess leads to pollution of the reservoir, given that the inhabitants of the aquarium do not need so much food. To solve the problem you need:

1. Study each phenotype contained in the aquarium.
2. Choose the optimal portion size and suitable nutrition, and do not go beyond the established limits when feeding.
3. Choose quality food.

In order to avoid difficulties with feeding, it is necessary to study in advance the theoretical aspects related to feeding and act in accordance with them.

It is important to ensure that rotting food does not appear.

overpopulation

Although many inhabitants will delight the eye of the aquarium owner and guests, this is not always justified and useful for fish, especially if they differ in character and behavior, which prevents them from getting along normally.

All these factors put the fish in a state of stress, worsen their appearance, shorten their lifespan, and in addition, the process of maintaining the tank becomes more complicated.

To prevent the occurrence of all of the above problems, including excessive foaminess and pollution, you can choose the right container and resettle the "residents" in comfortable aquariums. To do this, you can use the rule:

1. For 10 liters of water, one small fish.
2. For 20-30 liters - one big fish.

What can be done if there is white sediment in the water from the well

If you can afford a filter or better systems with an aeration column, ion exchange resins, etc., the problem disappears by itself. But if this is not possible, the following algorithm for purifying water in a well will help you. So, you need to carry out the following procedures:

1. Carrying out an audit, waterproofing the seams between the rings and inserting the pipe into the well.

Formation of a waterproofing layer on the upper rings.

Implementation of forced drying of the inner side of the rings, removal of silt and deposits located on the walls.

Cleaning or construction of a bottom sand-gravel filter.

Creation of a shungite bottom filter layer.

Disinfection of the walls of the well with a solution of a chlorine-containing agent like "Whiteness" (0.5 l of the agent per bucket of water).

Disinfection of contained water with a chlorine-containing agent.

Well water aeration device.

Choosing a good well cover.

How to remove white sediment in water by 100%

There are several ways to purify drinking water from hardness salts.

Reverse osmosis.
The principle of the method is that water passes through semi-permeable membranes (most often, polyamide). Together with hardness salts, most of the other salts also leave. The positive effect of such treatment can reach up to 99.9%. This technology is most common in domestic drinking water treatment systems. However, the method also has a drawback, it consists in the need to pre-prepare the water supplied to the reverse osmosis membrane.

Electrodialysis.
Salts from water, for example from a well, which give a white precipitate after boiling, are removed by means of an electric field. The ions of substances dissolved in the liquid are eliminated with the help of special membranes. Here, as in the previous technology, parallel removal of other salts is carried out along with hardness ions.

Thermal way.
Water simply heats up, due to which only temporary (carbonate) hardness is eliminated. Most often, this method is used in everyday life, but it is also used in industry, for example, at a thermal power plant.

Softening with reagents.
The method consists in adding to the water to choose from: soda, slaked lime. In this case, calcium and magnesium salts already familiar to us turn into insoluble compounds and form a white precipitate in water.This option is considered justified if it is necessary to treat a lot of water, since it entails the need for additional, rather specific steps: sediment filtration, accurate dosage of the reagent.

ion exchange.
In this case, an ion-exchange granular feed (usually ion-exchange resins) is used. Upon contact with water, it absorbs cations of hardness salts (calcium, magnesium), giving, in accordance with the ionic form, sodium or hydrogen ions. Therefore, such methods are called: Na+-exchange and H+-exchange. Normally, with single-stage sodium cationization, water hardness drops to 0.05–0.1 mg-eq / l, with two-stage - up to 0.01 mg-eq / l.

What is hard water

Hard water is usually called water in which there are too many salts of calcium and magnesium. They can be in the form of chlorides, sulfates, bicarbonates. Depending on their predominance, permanent and temporary stiffness are distinguished. The composition of water of the first type includes mainly chlorides and sulfates. They do not disintegrate under the influence of external influences - for example, boiling, do not settle. As a result, water indicators remain unchanged. To eliminate this shortcoming, special conditioning methods are required.

Temporary rigidity makes the presence of bicarbonates. Getting rid of them is much easier. For example, these compounds disappear on boiling. The problem of temporary stiffness occurs in 95% of all cases. According to the degree of severity, water is distinguished from very soft to very hard.

It is believed that having an artesian well means not having any problems with water. However, this is unfortunately not the case. Drilling a well is not a guarantee of normal rigidity.The moisture here is protected from pollution by sewage, agricultural fertilizers, industrial discharges and is stable in composition. While well water can change throughout the year, artesian water stays the same.

It is not possible pollution that makes hard water. This indicator depends on the composition of the soil through which moisture passes. So, the softest is in sandy soil, and the hardest is in calcareous soil.

This indicator is increased by deposits of gypsum, dolomite, from which salts of alkaline earth metals seep into the water. And these deposits can be located just where, as a result of drilling, a well is equipped or a well is dug.

Household with a pipe and professional with a pistol: are there any differences?

Manufacturing companies produce not only foam different in the number of components, but also different in the way of working with it.

In all hardware stores there are two types of sealant:

• household;
• Professional.

You can distinguish between these two types by looking at the cylinders. If the bottle comes with a special tube for blowing cracks, then this is a common household mixture. It is blown without the use of special devices like a construction gun.

These two types are different. Pistol professional polyurethane foam is able to expand 5 times more than standard household foam. This is due to the fact that with the help of a gun, the composition from the cylinder is squeezed out evenly. In the case of household formulas, many manufacturers resort to a small scam in the form of an increased amount of gas in the cylinder, which affects the actual volume of the substance. In household cylinders, squeezing out the entire mixture is problematic.

Manufacturers identify the main areas of purpose of this sealant:

• Noise isolation;
• Seal;
• Mounting properties;
• Thermal insulation.

Prevention is better than cure later

Finally, foaming of tap water can be minimized by using special combined water treatment agents that are added before filling the tank and perform a number of important functions:

• creating an optimal level of acidity;
• removal of suspended particles and harmful compounds;
• increase in temporary rigidity due to calcium and magnesium salts.

It is also important to remember to periodically change the water and clean the pond tank and equipment from silt and dirt. Take care of the pond, and it will always have clean, clear water without foam, through which the outstanding results of the invested labor are perfectly visible.

Take care of the pond, and it will always have clean, clear water without foam, through which the outstanding results of the labor invested are perfectly visible.

Hello! We have a well that has always had clean water, but now it is cloudy and foaming. Please let me know what could be the reason is it dangerous.

Scientists boil water without bubbles

Eureka » Discoveries

American physicists managed to accomplish the impossible - to make water boil without the formation of bubbles. They selected materials with such a surface that lowered the value of the Leidenfrost point for water to one hundred degrees Celsius. This technology will help shipbuilders design boards that will significantly reduce the friction of the ship on the water.

Every housewife knows perfectly well what the Leidenfrost effect is, even if she has never heard such a phrase.And this is just a phenomenon in which a liquid, in contact with a body much hotter than the boiling point of this liquid, creates an insulating layer of vapor, which prevents it from boiling away quickly. As they say, everything is simple and clear.

In everyday life, the Leidenfrost effect is most easily observed during the cooking process: water is often sprinkled on the pan to gauge the temperature. And if the temperature has reached or has already exceeded that very Leidenfrost point, then the water will collect into drops that will “slide” over the surface of the metal and evaporate longer than if it happened in a less heated frying pan. That is, if this effect is observed, then you can start baking pancakes or fry meat.

Scientists who are engaged in the study of this effect have long established one interesting feature. The fact is that the evaporation of the liquid during it occurs without the formation of bubbles. And all because the evaporation process takes place only at the boundary of the bodies, and not in the entire volume of the liquid. The very boundary layer of steam is to blame for all this - it is he who is the heat insulator, which does not allow the liquid to heat up all at once.

How white sediment in water affects household appliances, clothes, plants

There are a number of areas in our lives for which rigidity is, in principle, unimportant. So, any water can be watered lawns, put out fires. However, water hardness becomes a scourge not only when cooking and drinking, but also in everyday life: when washing, washing dishes, etc. Household appliances (washing machines, dishwashers, etc.), autonomous hot water systems, heating are afraid of increased water hardness.So, the fight against it is relevant. After boiling water, hardness salts precipitate into a white precipitate, familiar to everyone. Such scale reduces the duration of plumbing, household appliances, heating boilers, pipes.

How does water hardness affect household processes? In this case, there is an overrun of detergents when washing clothes, washing by 30-50%. Low consumer characteristics of water are also noted: during the preparation of coffee, tea, a brown precipitate may appear in such a liquid. Or while it is boiling, a film forms on the surface, and the water acquires a specific taste.

It is worth talking in more detail about the effect of water hardness on the results of washing and washing. The danger is that hardness salts, together with detergent compositions (soap, shampoo, washing powder), form “soap slags” that look like foam. When dried, they create the thinnest layer on the skin, hair, causing serious harm to their health. As a result, dry skin, brittle hair, peeling, itching, dandruff. One of the harbingers of such a negative influence is the characteristic “creak” of washed skin and hair. Special creams and masks allow you to restore the lost fatty film. But the “slipperiness” felt after washing with soft water is a guarantee of the preservation of the protective fatty film.

Cosmetologists all over the world choose soft water for washing. Since hard water when washing dry skin and allows the soap to lather as needed. Hard water, as we said, gives a white precipitate when boiled, but the same plaque forms on the walls of boilers, in pipes, etc. True, the preference for excessively soft water is not an option.

The fact is that it can cause corrosion, since it does not have such an important property as acid-base buffering provided by hydrocarbonate (temporary) hardness.

The main causes of cloudiness

Before you start cleaning, you need to find out what exactly caused the cloudiness. The main causes of water pollution include:

• ingress of soil particles due to depressurization of the walls;
• active development of microorganisms, for example, when exposed to direct sunlight;
• improper use and care of the device;
• stagnation during very rare operation of the well;
• a faulty pump, which during operation raises silty masses from the bottom;
• harmful chemicals entering the groundwater;
• decomposition of organic compounds accidentally found in the mine;
• mixing well water with sedimentary moisture falling from above due to the lack of a cover;
• improper arrangement of the above-ground part of the structure.

After determining the cause of the pollution of the well, you can begin cleaning work. They can be done on your own or you can seek help from specialists.

Soil particle pollution

If the turbidity of the water is caused by the ingress of soil or sand particles into it, a mechanical filter will help. If the dirt seeps along with the perch, it is necessary to put in order the broken sealing of the butt joints.

To clean a dirty well, you need to act in a certain order. It must be dried first. To do this, the contents are completely pumped out of the shaft using a pump.

A person in special clothes must descend into an empty well with a cable.Using a brush with a hard bristle or a special scraper, he will clean the inner surface of the accumulation of silt masses and dirt.

Layers removed from the walls and bottom must be collected in a bucket and lifted out. Cleaned surfaces should be treated with a disinfectant to remove harmful microorganisms and odors. All butt joints or cracks caused by water pressure should be sealed with a moisture-resistant compound.

How to make a clay castle? If the clay castle was not equipped during the digging of the well, the water will inevitably be polluted by precipitation. Therefore, it is necessary to provide protection from rain. A ditch 1 m wide must be dug around the above-ground head of the well. The minimum depth is 0.5 m.

In the prepared ditch, it is necessary to tightly lay the clay in several layers. Each layer is carefully compacted. Crushed stone or other bulk material is poured over the clay. The final layer is a cement mortar. With its help, a slope is formed from the mine to the side. This will ensure the runoff of rain and melt water from the structure.

Pump problems

Sometimes turbidity in the well is observed during pump operation. This occurs when the device malfunctions or is incorrectly installed. After checking and reinstalling, the pump can be connected.

If turbidity occurs again, you need to purchase a different type of pump - with a different liquid suction pattern. When buying a device, it is necessary to take into account the chemical composition of the water in the well. You can check it in the laboratory of Rospotrebnadzor.

Silting water

If the cloudy water has a yellow or greenish tint, then it is silting. This is due to an incorrectly laid and/or partially destroyed bottom filter.

In this case, it is necessary to drain the well. Then disassemble the bottom filter and extract it in parts to the surface. If bulk materials have become unusable, they must be updated.

Partially damaged gravel or crushed stone should be sorted out and washed. After that, the material can be reused, adding new masses if necessary. The bottom filter must be laid out again, carefully observing all the rules for its installation.

Water stagnation

If the well is rarely used, the water in it stagnates and becomes cloudy. In this case, it is necessary to drain its trunk. Thoroughly clean the bottom and walls of debris, silt, mucus and treat with a disinfectant solution. When the shaft is full, you need to add a solution of bleach.

To avoid stagnation, you need to periodically use the well. Additional cleaning will be provided by installing a special filter purchased at the store.

ferruginous water

With an increased iron content, well water becomes yellowish and acquires a metallic taste. If it settles, a precipitate will surely appear, resembling rust in color.

It is not dangerous to health, but it is unpleasant to drink it. The taste of dishes prepared with its use deteriorates noticeably. Special filters equipped with iron removal cartridges will help to correct the situation.

Summing up

So, how to check red caviar at home? Natural red caviar is distinguished by many visual and taste properties. And information about it can be obtained by carefully examining the packaging. So, if you are observant enough, at home you can check whether real red caviar or not. Buy quality products and enjoy the taste!

“Determining the quality of caviar is simple.Pour a few eggs with boiling water, stir with a spoon and see what happens. For caviar of good quality, the eggs will remain intact. If you stir it with a spoon, the water will turn white and become cloudy (the protein will curdle). Well, if the caviar is of poor quality, the eggs will dissolve in water in a few minutes.

New Year is a time of increased interest in red caviar. The word itself is associated with the holiday. But you need to have a special approach to the shelf with delicacy jars.

The contents of not every jar are good for health, and not all caviar looks appetizing, which is also important.
