How to save drinking water for a long time. About water and container: safe storage

From this article you will learn:

• In which package it is better to store drinking water
• Conditions and timing of storage of drinking water in plastic containers
• How to store drinking water with different properties

Currently, in order to cook or just drink, water must be cleaned with a filter or purchase in a store where it is sold in a 19-liter bottle or in small plastic bottles. In the same page, we usually store it at home. But is it right? What conditions and timing must be observed when storing drinking water, you will learn from our article.

What tanks are best used to store drinking water

First of all, it should be noted that it is necessary to properly store water in a closed container and certainly in glass.

If you do not have a similar container at hand, take a container from food plastic, which includes polyethylene terephthalate, polyethylene, polycarbonate, polyvinyl chloride (PVC), polystyrene and polypropylene.

The listed polymers are chemically inactive and harmless, but manufacturers for improving strength are added to them technological substances - stabilizers. As a result of chemical decay, hitting the water, they can have a toxic effect. We obtain the same effect with a debt of the storage of drinking water in a plastic container or after it is heated. In addition, polymeric materials, changing (older), distinguish decay products.

Polyethylene (Abbreviated PE) - thermoplastic saturated polymer hydrocarbon. As part of its molecules are ethylene links.

Water and other polar fluids do not wet polyethylene, in addition, room temperature Organic solvents do not act on it. When heated (up to +70 ° C and above), the PE swears and then dissolved in aromatic and chlorinated hydrocarbons. The best polyethylene is dissolved xylene, decalin and tetralin. Also at high temperature PE decomposes (usually pre-softened it).

Polyethylene resistant strong acids And alkalis, immacious to moisture. The organic solvents react in different ways (depends on the chemical base of the polymer), is physiologically dangerous.

Polyvinyl chloride (abbreviated PVC) - the product obtained as a result of complex chemical synthesis Based on natural materials - sodium chloride and petroleum hydrocarbons.

During the manufacture of polyvinyl chloride, the intermediate product is the BX (vinyl chloride) with the monomer structure. Next, during the polymerization, the monomers of the BX turns into PVC polymers. They are already completely inert and non-toxic. The final polymer contains only 0.1 PPM, although the PDC of toxins (maximum permissible concentration) in vegetable food should be 10 PPM.

To give PVC specific properties, various additives are applied - stabilizers, plasticizers and fillers. Stabilizers are divided into two types - CA / ZN (calcium / zinc) and even high-tech lead joints can be used.

Polyvinyl chloride is very popular due to its cheapness. From PVC produce disposable dishes, containers for household chemicals, cosmetics, bottles for water and beverages. After some time, PVC begins to highlight the Vinyl chloride. This carcinogen falls into the water, from it in food, and with food and in the human body.

According to research, the vinyl chloride begins to stand out a week after the liquid flooded in the plastic container. A month later, several milligrams of the WA accumulates, for example (according to oncologists, it is quite enough to develop an oncological disease). In no case cannot be used by plastic bottles again, although we see it completely and next.

Polystyrene. (abbreviated PS) - result from the polymerization of styrene (viniobenzene). This product is referred to thermopolymers class polymers (thermal exposure resistant). Its chemical formula [-CH 2 -CN (C 6 H 5) -] N -. Phenyl groups in polystyrene interfere with the ordered location of macromolecules and the creation of crystal compounds.

Polystyrene is characterized as hard and at the same time fragile amorphous polymer with a significant degree of optical light and low mechanical strength. IN finished video It is the colorless cylindrical granules.

PS density is low (1060 kg / m 3), thermal resistance - up to +105 ° C, shrinkage with injection processing 0.4-0.8%. It is an excellent dielectric, frosty (withstands the temperature to -40 ° C). It has small chemical resistance (except diluted acids, alkalis and alcohols).

For improving the quality of the PS, it is modified by mixing with other polymers - styrene copolymers are sewn and obtained.

Polystyrene dissolves in gasoline, toluene and acetone.

The basis of polystyrene's popularity is cheap, simple processing and a large range of various types. The most common impact polystyrene (their manufacture is over 60% of the total production of polystyrene plastics). These are styrene copolymers with different species rubber.

PS is inerton in relation to water and all sorts of liquids. But if you put in a similar container hot waterThis container will begin to highlight a toxic connection - styrene.

Polyethylene terephthalate (Abbreviated PET, PET) - Thermoplastic, resistant to elevated temperature. It is obtained by polycondensation of ethylene glycol with terephthalic acid (and its dimethyl ether). PET is solid, colorless, in amorphous state transparent, and in crystalline - white, opaque. Molecular weight is equal to (20-50) x10 3. PET is an excellent dielectric, durable, wear-resistant.

PET is chemically stable with respect to acids, salts, alcohols, gasoline, paraffin, fats, mineral oils, ether, is not dissolved in water, resistant to water vapor.

At temperatures from +40 ° C to +150 ° C, polyethylene terephthalate dissolves in such substances as acetone, benzene, phenol, toluene, cyclohexanone, ethyl acetate, carbon tetrachloride, chloroform.

Practically does not absorb moisture (hygroscopicity of 0.4-0.5%) - it depends on the phase state of the polymer and relative humidity air.

PET has a high heat resistance (melts at +290 ° C), collapsed at a temperature that is 50 ° C below the inert medium. It can be operated at a temperature of +60 ° C to + 170 ° C, thermostroduction is subjected at a temperature of +290 ° C to +310 ° C.

The destruction of PET flows statistically by the polymer chain. The PET includes volatile products such as terephthalic acid, acetic aldehyde and carbon monoxide. At a temperature of +90 ° C formed a large number of Miscellaneous hydrocarbons. In most part, volatile products consist of carbon dioxide, carbon monoxide and methane.

Now polyethylene terephthalate is used in the manufacture of the most different packaging for products and beverages, cosmetic and pharmaceuticals, video, audio and X-ray films, tires for cars and many other. This material has acquired its popularity due to the exceptional balance of PET capabilities, and also due to the fact that in the finished product it is easy to control the level of orientation and the degree of crystallinity.

PET without impurities is not toxic, but in its composition there may be phthalates and other toxic chemical compounds, dicarboxylic acids, glycols, etc., increasing the light, thermo-, refractory properties of the polymer.

In addition, the production of plastic containers for drinks can be used in BEF (bisphenol A). It violates the activity of the endocrine system, contributes to the development of breast cancer, leads to a hormonal imbalance.

Initially, British scientists said that the presence of BES in the human body is dangerous and can lead to the development of cardiovascular diseases, to diabetes. Further experiments were proved that in diseases of the liver and obesity, the BFA level was also exceeded, but could not connect it using plastic containers, and in their composition traces of formaldehyde.

On the back of the bottom of dangerous tanks, conscientious manufacturers put an icon with a number 3 in a triangle or PVC write (which means PVC). Also, such a bottle is recognized according to the characteristic influx at the bottom in the form of a line or spear in two ends. When you click on a dangerous tank, the white trail remains. Quality containers will remain smooth.

Terms and conditions for storing drinking water in plastic containers

Nowadays, the number of plastic water bottles in stores is growing steadily. Bottled water can be ordered with home delivery. Hypermarkets willingly realize such water, as she has a largest storage.

Under normal conditions, water under the influence of sun rays and heat quickly loses its properties, and because of the bacteria that fell into it, there is an unpleasant smell and taste. But why is the water stored in supermarkets for a long time? The fact is that manufacturers can be preserved this water.

Mix three methods of conservation:

• ozonation;
• gasing;
• adding an antibiotic.

The first two methods are harmless, but such a liquid is stored only until the bottle is revealed, that is, as soon as you unpacked the container, water from it should be served over the next few days.

Drinking water was installed by the third way is kept long, but antibiotics can cause serious harm to your health and immune system.

Bottled water should be stored in a dark place at a temperature of + 15 ... + 30 ° C. It is better to purchase recently spilled in your area - more useful substances in it.

Water storage tank should be made of plastic corresponding to the food class. If there is a PET icon on it, then it is made of polyethylene terephthalate, which does not react with liquid and not toxic. In no case cannot store water in the PVC bottle - this means that it was made from toxic material. In addition, the liquid that is stored in tanks from melamine is dangerous.

In case you did not find any marks on the bottle, then check the material is the material, it is quite simple. Press the nail to the container. On a dangerous you will see a whiten mark, you will not notice changes on the bottle from PET. Touch the bottle if the sound is deaf, then the container is made of melamine.

The shelf life of water canned in a bottle of plastic - from 6 months to a year. At the same time, after opening, you can store drinking fluid about 10 days.

At drinking water, in addition to the shelf life, there is also the so-called period of "utility", after the end of which it loses most of its useful properties. Therefore, you need to acquire as fresh water as possible.

Features of drinking water storage with different properties

According to manufacturers, water in plastic containers can not only be stored, but also necessary.

Plastic containers for storing drinking water are mainly made from polyethylene terephthalate (PET (E)), which corresponds to the food class and neutral, that is, does not react to water and harmful to health. Plastic marking is usually squeezed on a bottle. Of course, there are also plastic capacity of the PVC class (this material toxic) or from melamine (in such bottles it is impossible to store water at all). From 6 to 12 months from the date of bottling - it is just such a shelf life that has a liquid in plastic bottles.

Water water For storage, you should first filter, and then pour into the enameled, glass or plastic (PET) bottle without closing the lid to give to settle (for example, night) to destroy chlorine.

After that, the water bottle should be closed tightly and stored in the refrigerator or at room temperature for no more than two or three days.

If you drink only boiled water, Keep it in a tightly closed enameled dishes in a small amount, no need to boil about the reserve.

Storage term boiled water Depends on its primary quality, composition, degree of cleaning. It is known that boiling kills all bacteria, including useful. But with a long storage in liquid, microorganisms from external environmentAnd the whole effect of its boiling is reduced to not. Therefore, it is not recommended to store it for more than 12 hours.

Cleaning or spring water We advise you to maintain in glass or ceramic (clay) tanks. In hermetic form, its natural useful properties are preserved for three years. Metal containers for storing drinking water should be used exclusively enamelled or with a different neutral coating inside.

Pour spring water only from proven sources, another drinking is dangerous for health!

Today a lot argue about the utility structured water and its positive impact on the human body, including in the cell and gene level. Such a frosthed water can be easily stored in a glass container.

It is best to store structured water in stainless steel dishes or metallic with an admixture of silver in a place where the straight sunshine does not reach. Russian scientists have shown that the effect of structuring of the fluid increases significantly in silver dishes in the light by about 7.5% for two hours.

If the quality of water leaves much to be desired ...

The problem of dirty water in the house can be partially solved by installing a high-quality filter, but in such systems it is possible to replace the components periodically, because it directly depends on how well the drinking fluid will be cleaned.

At the same time, the question remains unresolved: how to achieve in our workplace or a child in school there was the best quality water? The best solution is to buy it with delivery.

The company "Iceberg" offers favorable conditions for servicing its customers:

• free shipping water to the house or office: Buyers pay only the cost of goods;

Clean water is value, but it should not be on gold weight. Our mission is to provide every home and workplace with high-quality drinking water, so we have prepared the most favorable conditions for our customers.

The effect of water on a person's condition depends largely and on how it is stored. Let's talk about how to properly store water so that it is beneficial for health and remained fresh.

Drinking water storage rules

Water quality plays a large role in determining the appropriate storage period. For long-term storage, well purified drinking water is suitable, poorly purified water will quickly turn in any capacity.

• You can choose different water tanks, depending on its use: Glass, plastic, metal. Most often for water storage use plastic and glass containers. Small volumes of water are more convenient to store in plastic bottles with a lid. If you stopped on the plastic, choose PET bottles (Pet Bottle). They are made of polyethylene terephthalate, which does not spoil water.
• Pvc-containers are unsafe, can "infect" water to toxins. Also do not use the PVC and BFA tanks.
• The water storage temperature should not exceed +25 degrees, it is also necessary to ensure that direct sunlight does not fall into the water container.
• If you bought the water in the store, then follow the timing designated on the bottle.
• The container in which the water is stored should be tightly closed, otherwise the beneficial substances will soon die. Also in open container, water is stored for a short time, because oxygen, falling into the water, changes its chemical composition.
• Bottled water can be stored in polycarbonate bottles for twelve months. In glass container, water can be stored from three months to two years, in PET containers - from three months to one year.

Water plays an important role in biochemical processesoccurring in the human body. Our health and well-being directly depends on the quality of drinking water. If you do not know how to store water That's right, you can make it very harmful, your health.

Everyone knows that spring water has the most useful taste. City inhabitants, far from natural spring, drink tap water, which is chlorized to protect against pathogenic bacteria. But it does not save it from harmful microorganisms. To avoid unpleasant consequences, tap water must be boiled or passing through the filter.

What and where to store water

A large influence on the quality of water has dishes, a place and storage temperature. Studies of scientists have proven that the molecules of materials from which storage containers are in different ways affect the structure of water molecules. Therefore, it is important that water is nanite.

A large amount of water (for example, in the country) is recommended to be stored in wooden or ceramic dishes. Thanks to their properties, water remains suitable for drinking up to 3 days.

A positive effect on the preservation of the molecular structure of water, and accordingly, silver ions are rendered on its quality. Silver containers are the best water storage.

The value of sunlight

Thinking on how to store water, do not forget about the effect of light.
According to the conclusions of scientists, the content of structural elements in the non-filled water is gradually reduced in the dark. And, on the contrary, changes in the positive side are under the influence of scattered light. It is noticed, just that if the tap water is pouring into a glass decanter, give it well to settle with the scattered sunlight, its structure almost does not change during the day. While in a plastic bottle stored in the refrigerator, changes for the worse occur 10 minutes. Therefore, it is useful to store water into the light.

Optimal water storage temperature

The most acceptable temperature is 7-12 degrees. It slows down the processes of microorganisms reproduction, it remains transparent and thirstfully quenched thirst.

Mineral water can be stored at a lower temperature - from 4 to 10 degrees. Glass bottles must be horizontal.

Water in a plastic bottle is stored in the refrigerator. In the summer at temperatures above 30 degrees, plastic begins to extract toxic substances into water.

So, in order not to harm your health and enjoy drinking water, the best thing to store water in silver or glass dishes on the scattered sunlight at a temperature not higher than 15 degrees.

Pure drinking water is the most important resource for a person. Proper storage of drinking water is an equally important aspect than the choice of water itself.

Drinking water storage conditions

To preserve the properties of drinking water, it is recommended to be stored at a temperature not higher than 25 degrees, but not on direct solar rays. Remember also that with long-term storage, water loses its qualities, so it is not necessary to stock it too much. Allowable dates for drinking water storage depend on the container used. If you buy bottled water, always pay attention to the storage period specified by the manufacturer and do not disturb it.

Drinking water storage container

Today there are many types of containers: plastic, clay, metallic, glass. In glass tank, water can safely be stored up to 3 years. In principle, this is the most recommended option, but not always practical. A small amount of water (up to 50 liters) can be stored in a special plastic container with spinning lids. And if you need to store a large amount of water, then the spare package is better used from food plastic or specially treated metal. The most dangerous containers from melamine are most dangerous: although they are aesthetic and durable, but at contact with water, they distinguish harmful substances.

If you buy and store water in a plastic bottle, pay attention to its composition. The most secure package are bottles of polyethylene (PE) and polyethylene terephthalate (PET). But the content of bisphenol A (BTU) and polyvinyl chloride (PVC) is fraught with the release of toxins in 5-7 days. And the reuse of such containers is prohibited.

Observing the basic requirements for the storage of drinking water, you ensure the preservation of its beneficial properties and safety for the body.

Hello!

I have this question. In which package it is better to store water? As far as I understood, it is better in transparent, to hit ultraviolet. But therefore the next question. I studied on Himphic, the polymers were studied, according to my information, polymers can allocate some substances at a temperature of over 20 degrees Celsius. Glass remains or in last years Science crossed my knowledge and now packaging from polymers harmless?

Thank you in advance for your response.

Hello!

Store water best in glass closed container.

If there is no such possibility, it is better to use a container made of edible plastic, which is made of polyvinyl chloride (PVC), polypropylene, polyethylene, polystyrene, polycarbonate and polyethylene terephthalate.

These polymers are chemically inert and non-toxic, but technological additives are stabilizers, which are added by manufacturers to increase strength, as a result of a chemical decay that occur to water, can have toxic effects. It can also occur with long-term storage or water heating. In addition, polymeric materials, subject to change (aging), allocate degradation products.

The main polymeric materials used in the manufacture of plastic containers are shown below:

Polyethylene (indicated by PE) - thermoplastic saturated polymer hydrocarbon, whose molecules consist of ethylene units.

PE is not wetted with water and other polar fluids. At room temperature, it does not dissolve in organic solvents. Only with an increase in temperature (70 ° C and higher), he first swells, and then dissolved in aromatic and chlorinated hydrocarbons. The best solvents are Xylene, Dealin, Tetralin. When heated (often with pre-softening), PE decomposes. Not sensitive to humidity, resistant to the action of strong acids and alkalis, the ratio to organic solvents is different (depending on the chemical nature of the polymer). Physiologically PE is harmless.

Polyvinyl chloride (designated PVC) -product complex chemical synthesis, the basis of which is the natural raw material - sodium chloride and oil hydrocarbons. In the production of PVC, the intermediate product is in (vinyl chloride) having a structure of monomers. They are then in the process of polymerization turn into PVC polymers. The latter, in contrast to biologically active monomers, are absolutely inert and not toxic. The final content of the BC in the polymer is 0.1 PPM, while the maximum permissible concentration (MPC) of toxins in plant foods is equal to 10 PPM. To give PVC, various additives are used, such as stabilizers, plasticizers and fillers. Modern stabilizers are two types - Ca / Zn (zinc calcium) and even lead compounds with high toxicity. PVC is distributed worldwide, because Extremely cheap. It makes bottles for drinks, cosmetics boxes, containers for household chemicals, disposable dishes. Over time, PVC begins to highlight a harmful carcinogenic substance - vinyl chloride. It enters the water from the bottle, from the plate - to food, and with food and in the body. According to experiments, harmful substance From PVC begins to stand out a week after the contents flooded. A month in B. mineral water A few milligrams of vinyl chloride accumulates (oncologists believe that it is enough to develop onco-scabs). Often, plastic bottles are used again: water or other drinks are poured into them, even alcoholic. In markets, milk and sunflower oil are sold in the markets, which is extremely undesirable.

Polystyrene. (denoted by PS) - the polymerization product of the styrene (viniobenzene) refers to the polymers of the thermopolymers class, i.e., polymers resistant to thermal influences. It has a chemical formula of the form: [-CH 2 -CN (from 6 H 5) -] n -. Phenyl groups in the composition of the PS are hampered by the ordered location of macromolecules and the formation of crystalline formations. PS is a hard, fragile, amorphous polymer with a high degree of optical light, low mechanical strength, produced in the form of transparent cylindrical granules. Polystyrene has a low density (1060 kg / m³), \u200b\u200bthermal resistance (up to 105 ° C), shrinkage at injection processing 0.4-0.8%. PS has excellent dielectric properties and good frost resistance (up to 40 ° C). It has low chemical resistance (except diluted acids, alcohols and alkalis). To improve the properties of polystyrene, it is modified by mixing with different polymers - subjected to crosslinking, receiving styrene copolymers. PS dissolves in acetone, toluene and gasoline. The wide use of polystyrene (PS) and plastics based on it is based on its low cost, ease of processing and a huge assortment of various brands. The widest use (more than 60% of the production of polystyrene plastics) was obtained by impact-resistant polystyrene, which are styrene copolymers with various types of rubber. To water and cold ps fluids inert. But when placed in it, hot liquid or water containers from the polyterol can highlight some amounts of toxic compound - styrene.

Polyethylene terephthalate (denotes PET, PET) - thermoplastic resistant temperatures, etylene glycol polycondensation product with terephthalic acid (or its dimethyl ether); solid, colorless, transparent substance in amorphous condition and white, opaque in crystalline state. Molecular weight (20-50) · 10 3. Pat is durable, wear, good dielectric.

PET does not dissolve in water and has a large chemical resistance in relation to acids, salts, alkalis, alcohols, gasoline, paraffins, fats, mineral oils, and ether. PET also has high resistance to water vapor. PET material dissolves at 40-150 ° C in acetone, benzene, phenol, toluene, cyclohexanone, ethyl acetate, carbon tetrachloride, chloroform. PET has low hygroscopicity (water absorption is usually 0.4-0.5%), which depends on the phase state of the polymer and relative humidity. Characterized by high heat resistance (290 ° C); The destruction in the air begins at a temperature of 50 ° C lower than in an inert medium. PET operational properties are preserved in the range from - 60 to 170 ° C. Polyethylene terephthalate is subject to thermal decolation at a temperature range of 290-310 ° C. PET destruction passes statistically along the polymer chain. Volatile products are terephthalic acid, acetic aldehyde and carbon monoxide. At a temperature of 900 ° C, a large number of various hydrocarbons are formed. Basically, volatile products consist of carbon dioxide, carbon monoxide and methane.

In the cold and heated state, PET retains excellent plasticity. The thermoforming process is simple and high-tech due to the fact that the material has minor internal stresses. PET does not require pre-dry, as the heat capacity of the material is significantly less than that of polystyrene and plexiglass. PET allows you to save on electricity and significantly reduces the complexity, because significantly less thermal energy and time for molding temperature are necessary. All this ensures a decrease in production costs. Thus, polyethylene terephthalate can easily replace the transparent solid polycarbonate, possessing the cost below.

Apply PET for the production of polymer fibers, threads, containers and packaging.

World PET production in 1989 amounted to about 9.3 million tons, and 90% of the total PET is spent on the production of packaging-in fibers.

For the first time, the fiber-forming polyethylene terephthalate was synthesized in the UK in 1941.

Today PET is used to produce a variety of packaging for products and drinks, cosmetics and pharmaceuticals, PET materials are indispensable in the manufacture of audio, video and x-ray films, automotive tires, bottles for drinks, high barrier properties, fibers for tissues. A wide range of applications is possible due to the exceptional balance of PET capabilities and the fact that the finished product is the degree of crystallinity and the level of orientation can be monitored.

Speaking about PET toxicity, it should be noted that pure PET is not toxic. However, PET can contain phthalates and other toxic chemical compounds, dicarboxylic acids, glycols, etc., which are injected into the polymer to increase thermo-, light and refractory properties.

In the manufacture plastic bottles Also, the inogdd is used bisphenol A (BTU) disrupting the work of the endocrine system, provoking breast cancer and leading to a hormonal imbalance. It should be especially paid to the attention of parents to use plastic bottles for feeding children.

Initial studies English scientists have shown that the presence of BFA in the human body can lead to the risk of sugar diabetes and cardiovascular diseases. Subsequent experiments led to more restrained conclusions. It was proved that in diseases of the liver and obesity, the content of BFA in the body is also increased, but it failed to connect this phenomenon with the use of plastic containers. In addition, in the composition of plastic bottles are traces of formaldehyde.

Conscientious manufacturers put the icon on the bottom of dangerous bottles - the top three in the triangle, or PVC, i.e. PVC. Harmful containers can be recognized in the influx on the bottom. It happens in the form of a line or spear in two ends. If you click on the bottle of a nail, a born scar is formed on a dangerous. The right bottle remains smooth.
