Usage various types filter devices is the main way to obtain clean drinking water, with the most common systems containing coal. For a consumer who independently purifies water from a public water main or an individual source of water supply (borehole, well), it is useful to know for effective use what a carbon filter for water cleans, its types and areas of application.

The use of charcoal has been known since ancient times; even now, in order to save money, craftsmen make similar charcoal cleaning filters on their own. It is also difficult to imagine modern water purification filters without the presence of carbon fillers; they are used both independently and as part of various types filter systems.

The operation of coal as a filter element is based on its sorption qualities - the ability to absorb various components from water due to its porous structure. By the nature of binding of substances found in an aqueous environment (sorbates), activated carbon belongs to adsorbents - substances that concentrate sorbate at the phase interface (the boundary between the solid surface of carbon particles and liquid) or absorb it with its surface layer. That is, coal differs from materials that absorb various substances from the aquatic environment and distribute them throughout the entire volume (this effect is called absorption).

Thanks to the adsorption properties of coal, that is, its concentration of harmful substances on the surface, the operating principle of many carbon filters, which use the technology of periodic cleaning and restoration of the original state of contaminated carbon-containing filler by washing with a strong reverse flow of water, becomes clear.

Unlike the technology of ancient and self-made carbon filters, modern water purification devices use activated carbon - a porous component obtained by special processing of carbon-containing materials: charcoal, coal, coke from oil refining, coconut shells. After processing, the material receives a huge number of pores, and its surface area increases in the same proportion. Depending on the technical process of coal activation, 1 gram of the substance has an area from 500 to 2200 square meters- this significantly increases its adsorption qualities in comparison with conventional untreated coal material.

In addition to the adsorption process, through which coal removes polluting components from water, when it interacts with certain substances, a chemical reaction occurs - catalytic oxidation.

As a result of this oxidative reaction, free chlorine is converted into hydrochloric acid, which is then neutralized by the bicarbonate alkalinity of the water. The considered process of eliminating chlorine is called dechlorination, while activated carbon does not decompose and is not consumed.

Thus, the strong oxidizing agents chlorine and chloramine contained in water, entering the activated carbon environment, are removed from it due to catalytic oxidation, and other organic and inorganic components are absorbed when the adsorption mechanism is activated.

Peculiarities

Although municipal tap water satisfies most requirements state standards(GOST), sanitary norms and rules (SanPiN), higher international standards make it unsuitable for drinking in a wide range of parameters. The use of carbon filters can bring health benefits by eliminating the following negative properties from water or significantly reducing the concentration of the following types of contaminants:

Free chlorine. A substance harmful to health that impairs the smell and taste of water is contained in it as a result of disinfection used to destroy a large number of different types of pathogens and bacteria. Chlorine-containing components are removed by catalytic oxidation.

Organic. These types of contaminants are present in water due to the ingress of organic decay products of living organisms and their waste products, which are adsorbed during filtration.

Organochlorine compounds. As a result of complex chemical reactions of free chlorine with organic matter present in water (human and animal waste, decay products of living organisms), organic compounds that are very harmful to human health are formed - trihalomethanes, which include chloroform, bromodichloromethane, dibromochloromethane and tribromomethane. They accumulate in vital organs (liver, kidneys) and can cause cancer due to their high carcinogenic properties.

Petroleum products and inorganic compounds. Carbon filters, due to adsorption, effectively absorb gasoline, fuel oil, phenols, benzenes, etc. from water. Purification reduces oxidation levels, the concentration of radionuclides, ammonia, nitrates, pesticides, epoxides and their derivatives contained in water.

Smells and tastes. A carbon filter for water purification, together with the elimination of chlorine, the adsorption of insoluble lime, bacteria and microorganisms, improves its taste and destroys the odors of chlorine and mud.

Chroma. Coal absorbs organic and clay suspensions, green algae, and insoluble ferric iron, which gives the aquatic environment a reddish tint - these factors help reduce color and increase water transparency.

Types of coal used

The raw materials for the production of activated carbon are natural materials, they are first charred and then subjected to an activation procedure. The essence of the technical process is to open microscopic pores closed in ordinary coal. Activation is carried out by the thermochemical method, impregnating the coal mass with potassium carbonate, zinc chloride or other solutions, after which it is subjected to heat treatment without the presence of air.

The second method of activating coal is treating it with superheated steam, carbon dioxide or their mixture at a temperature of 800 - 850 °C. Since it is difficult to obtain a vaporous medium from water with such temperature parameters, technology is practiced with additional feed air into the working area, while part of the processed coal burns, which significantly reduces the yield of the activated component.

Technology allows you to receive best brands activated carbon specific surface area is from 1800 to 2200 square meters per 1 g of substance. The pores themselves are divided into the following categories based on their diameter:

• Macro— have a diameter of more than 50 nanometers (nm), pores of this size are typical for activated carbon beds based on wood raw materials.
• Meso- pores ranging in size from 2 to 50 nm are present in overwhelming quantities in the activated composition obtained from coal.
• Micro- pores with a diameter of less than 2 nm are found in activated carbon obtained from coconut shells.

The raw materials for producing activated carbon are the following:

• Wood, it is charred without air access, and then activated. The coal obtained from it with large pores is used for dechlorination of water and its rough purification at the preliminary stage when the water supply enters the house, in homemade purification devices.
• Hard or bituminous coal after activation, it is able to capture pesticides, phenols, clarify and rid water of chlorine and its odor.
• Coconut shells. Activated carbon obtained from this material is used in most water filter systems. Thanks to small pores and a correspondingly large working surface, the component activated from charred coconut shells is capable of absorbing a significant amount and a wide range of elements from the aquatic environment that are harmful to human health.

Additional components of carbon filters

In addition to activated carbon, the following additional components are often used in filters:

Synthetic fibers. Synthetic materials are used in filter cartridges as elements of mechanical water purification (discs at the cartridge inlet) from large insoluble impurities, preventing their penetration into the coal mass and clogging its channels. Also, filters made of synthetic porous materials are placed at the outlet of the cartridges for post-treatment, retaining the backfill and preventing it from getting into the water.

In some filter systems (Aquaphor), the carbon bed is mixed with synthetic fibers, which compact its structure and maintain its shape. As a result, a dense mass of activated carbon more effectively purifies the water flow from harmful impurities.

Zeolites- natural minerals, hydrated calcium and sodium aluminosilicates, resembling cloudy glass or mother-of-pearl in appearance, are known for their ability to absorb and release water depending on conditions environment. Another one distinctive feature zeolites - the ability for cation and ion exchange by absorbing and releasing various substances with their surface structure.

Shungite— (slate stone) rock of the Precambrian period, consisting of 99% carbon, the structure is very similar to graphite. The mineral has been known since ancient times as an excellent natural water purifier; in the times of Peter the Great, shungite water sources were credited with miraculous healing properties, and soldiers were recommended to carry shungite stone with them on campaigns and purify water with it. Currently, shungite is known as a mineral with high absorbent (sorption) and catalytic properties, and it is also an excellent antioxidant.

Ion exchange resin used to soften water, in appearance it resembles small fish caviar with a diameter of no more than 1 mm in brown, yellow, dark colors. The resin exchanges ions with salts of water-soluble metal oxides (calcium, magnesium, iron, manganese), as a result of which they adhere to the surface of the round granules. When sodium chloride (NaCl) salts are added to water, a regeneration process occurs; harmful metal salts are separated from the surface of the ion-exchange resin beads and washed down the drain.

Antibacterial additives. To combat the proliferation of microbes and bacteria and disinfect water, silver ions in the form of small gray balls are often added to carbon filters.

Quartz fine gravel. It is used as a supporting backfill, allowing the flow to flow evenly when the purified water passes through the coal layer, and is used in large-sized carbon-containing systems for purifying large volumes of water.

High purity zinc and copper. These substances are part of one of the latest patented innovative developments - the KDF (Kinetic Degreadation Fluxion) filter bed, which has a higher productivity and degree of water purification from harmful impurities in comparison with traditional fillers. In addition to metals, KDF contains activated carbon and ion exchange resins.

What filters use carbon in their composition?

When purifying water to potable condition, the following factors are taken into account. Typically, chlorinated water is supplied to apartments by public utilities, and the amount of harmful elements it contains is standardized. To combat chlorine and metal salts, if water is used for drinking purposes, you can use ineffective options for settling or boiling water.

But considering that carbon filters do an excellent job with bleach, their use in this case will bring a more pronounced effect and save time on dechlorination. Therefore, for water purification only for drinking purposes from public water mains, most consumers use small-volume carbon-containing filters.

If an individual plot has an autonomous or well source, other filtration systems will be needed. Often water enters a house from shallow water layers, which include wells or. In this case, there is a high probability that contaminated surface water, various types of microorganisms and microbes, and organic impurities will enter the water basin, while the water itself usually contains a small amount of metal salts, which give it hardness and impair color and taste.

In this case, the use of water purification carbon filters not only for drinking purposes, but also for domestic use is optimal solution, and many users install large-volume coal tanks for cleaning work.

A carbon filter for water purification, if it is used in an individual area with clean water, usually containing only a high content of metal salts from harmful elements, is not so necessary. In treatment systems for artesian wells, installations are mainly used for iron removal, and carbon filtration is used for post-treatment.

Jug filter cartridge Barrier - device

Jugs

The simplest and most popular type of water purification filters for public water supply networks at home is a device in the form of a jug with a replaceable cartridge. According to user reviews, the sorption cartridge in a pitcher-type filter in urban water supply conditions is usually enough to provide a family of three people with water suitable for drinking purposes for a month.

The filling of cartridges from different manufacturers may differ not only in composition, but also in the quantitative ratio of various components.

Most cartridges from well-known manufacturers (Aquaphor, Brita, Barrier, New Key) are filled with activated carbon obtained from burnt coconut, beads with ionic silver are added to fight microbes, and ion-exchange resin is used to soften the water.

Note: Thus, household pitcher filters clean water from chlorine, partially remove metal salts and adsorb insoluble particles of other pollutants.

Flow-through jug filter - filling, design

Flow-through

A flow-through carbon filter is installed in the cold water main as an attachment on the faucet, under the sink in the pipeline, or used in a separate jug with an outlet spout (Spring) connected to the cold water main. The composition of these cartridges is slightly different from jug modifications, since water is supplied under pressure, the productivity of such systems and the degree of purification are slightly higher than that of gravity-flow devices.

Trunk

Reusable carbon-containing water is installed in individual water supply systems of private houses. Structurally, they are made in a glass-shaped body, inside of which a tubular cartridge with filler is placed. The housing is hermetically sealed with a threaded lid and a gasket, which has two holes at the top for connection to the water main.

Water enters the filter through the inlet and, after cleaning, is sent to the consumer. At the bottom of the glass there is a tap for backwashing the carbon filler of the cartridge from contaminants.

Main carbon cartridge - design

Reverse osmosis plants

The principle of water purification in reverse osmosis systems (popular brands of such installations are Bosfor, Agua, Geyser, Barrier, Atoll) consists of supplying liquid through a thin-walled membrane with ultra-small pores under pressure, resulting in distilled water without metal salts at the output, which cannot be achieved in any one of the carbon filters reviewed.

For efficient work Reverse osmosis installations must receive the most purified water at the inlet; therefore, in a standard system, three flow filters are used to purify it, two of which have activated carbon as the main component.

The following types of carbon-containing filter fillers are used in reverse osmation installations:

Granular Activated Carbon (GAC). Made from burnt coconut shells, the component effectively purifies water from organics, pesticides, chlorine contaminants, viral and bacterial organisms, and removes foreign odors. The useful area of ​​1 g of this substance reaches 1000 square meters.

Granular Carbon with KDF (GAC-KDF). The additional presence of KDF components in the backfill makes it possible to effectively remove from water, in addition to biological, hydrogen sulfide, pesticide, phenolic, and benzene contaminants, also heavy mercury, cadmium, lead, and ferrous metal salts.

Pressed activated carbon from coconuts SBC (carbon block). Compressed high-quality carbon is a sorption filter that perfectly removes organic matter, chlorine compounds, petroleum products, and pesticides from flowing water. After cleaning, foreign odors are eliminated and the taste of water is improved.

Balloon type

Carbon filters of significant volumes are used for water purification in industrial scale and public utilities for a large number of consumers. Their main structural element is a container with a lid made of food-grade high-density polyethylene and fiberglass.

The lid contains connections for inlet and outlet of filtered water, a drainage pipe, as well as a control unit that automatically sets operating modes for cleaning the system, which allows you to restore the original state of the carbon filler. The backfill consists of activated carbon and a gravel substrate of purified and etched quartz with a fraction size of 2 - 5 mm, the purpose of the gravel is to uniformly distribute the water flow.

When the sorption filter is operating, water enters the container through the inlet pipe and passes through the activated carbon filler from top to bottom, then it enters a water-lifting pipe with a filter basket at the end, lowered into the gravel backfill, and is sent along it to the consumer through the outlet pipe in the lid.

In rinsing mode, water with high pressure it is fed in the opposite direction: through the water-lifting pipe down through the filter basket and gravel backfill, agitates the layer of activated carbon and is discharged out through the drainage pipe. At the end of backwashing, the loosened layer of activated carbon is compacted by direct washing, passing water for a short time with high speed from top to bottom and lowering it into the drainage. Thanks to washing procedures, the resource of the coal bed in sorption filters reaches one to two years.

Homemade

To save money, many consumers of water resources make a simple, effective carbon water filter with their own hands using technology developed many centuries ago on different continents. To do this, a slot is made at the top of a 6-liter bottle to fill in the filter components, a number of small holes are drilled in the cork and it is closed with inside cotton pads.

Then crushed activated charcoal (obtained by steaming burnt raw materials), its larger fractions, and fine and coarse-grained river sand are poured into the bottle. A water bottle with a carbon filter can be useful on a long hike if you need to collect contaminated, cloudy water from a stream or other source, then filter and boil it.

Advantages and disadvantages

The use of carbon filters has the following advantages and disadvantages:

• When coal purifies water from chlorine, a catalytic chemical reaction automatically occurs, and the coal fraction is practically not consumed - this property of coal makes it an indispensable component in the dichlorination of water.
• Although activated carbon purifies water from a wide range of harmful impurities, it cannot adsorb lead, mercury, cadmium, and iron salts heavy metals in traditional filter systems. This disadvantage eliminated in modern KDF fillers with copper and zinc, which have not yet found widespread use in cartridges for popular jugs.
• The average service life of replacement jug cartridges is limited to two months, after which cleaning efficiency is lost and replacement is required. It leads to financial expenses, which for some families can be quite significant. In sorption filters, it is also necessary to change the backfill after 1 - 2 years; due to its large volume, the cost of purchasing new activated carbon can significantly hit the family budget.

Activated carbon filters are an effective and cost-effective way to purify water from a wide range of harmful impurities and especially chlorine. After passing through the carbon-containing backfill, all its organoleptic characteristics are significantly improved. In many purification systems, carbon filtration is an additional unit for preliminary or final water purification.

Activated carbon is used for water purification, in a wide variety of installations, in a variety of cases. The most primitive device based on it is a homemade filter. Hunters and fishermen often build a simple structure from coal, cotton wool, sand and plastic bottle for purifying moisture while traveling.

Coal is used at water treatment plants to remove impurities from liquids and improve its taste. These are places where a huge volume of water is purified and intended to be supplied to the population. Of course, the coal-based devices there are large-scale, well-thought-out and modern.

Activated carbon is also used in the field of wastewater treatment, i.e. liquids from enterprises, settlements, or atmospheric precipitation. Used as part of the physical and chemical purification stage.

But we decided to devote this article to activated carbon, which was adopted by some manufacturers of household water filters, namely, carbon obtained from coconut shells. Why did manufacturers like this material? For which filters can you buy water cartridges based on this substance? Read about this and much more in this article.

How is regular coal different from coconut coal, and why is it used in water treatment?

Regular activated carbon is most often obtained from oak, spruce, birch, and pine. It certainly has excellent sorption properties and is used for water purification, in the production of medicines, and for other purposes. However, coconut charcoal is more efficient, more environmentally friendly, and safer.

Due to its structure, this material has improved sorption capabilities, i.e. provides much better water purification compared to conventional coal. This is due to the fact that the coconut version has a larger total area of ​​all filter pores. This is what attracted the attention of manufacturers of water purification equipment. Activated coconut charcoal is used to:

• reduce the concentration of chlorine and chloride compounds in water,
• reduce the concentration of organic compounds in water,
• improve the taste of water,
• remove foreign odors from water.

It is not surprising that most often the main filter material in household filters is coconut activated carbon. On its basis, cartridges are manufactured for jugs and flow-through devices; they are part of reverse osmosis systems. Coal can be in granular form and pressed (carbon block technology).

The Aquaphor company also developed and patented a fibrous material made on the basis of activated carbon - Aqualene.

What functions do activated carbon cartridges perform in filters?

If we talk about simpler household filters, for example, pitcher filters, then the task of the cartridge is very, very important - to remove maximum amount impurities. After all, there are no other cleaning elements in the device. Flow systems, for example, Geyser filters, usually purify water with several cartridges. One, for example, is made of coal, and the other is based on an ion exchange resin to soften moisture.

Also, cartridges containing carbon from coconut shells are part of classic reverse osmosis systems. There they are needed in order to:

• prevent damage to the reverse osmosis membrane by chlorine and its compounds,
• improve the taste of water leaving the system after being in the storage tank.

Reverse osmosis filters Atoll, Geyser, Atlantic are equipped with the most reliable and efficient cartridges based on high-quality, specially activated coconut carbon. By purchasing products from these manufacturers, you can be sure that the device will work reliably.

Conclusion.

Coal made from coconut, allows you to achieve a high level of sorption water purification. Used in modern household filters for purifying life-giving moisture. Based on it, cartridges are produced for a wide variety of devices.

Properly done carbon filtration (purification) of moonshine not only partially removes harmful impurities, but also forms a characteristic vodka flavor in grain and sugar distillates. Due to its availability, experienced distillers are increasingly using activated coconut charcoal (brand KAU-A), which has several advantages over similar birch charcoal.

Theory. Activated coconut charcoal is a natural, environmentally friendly absorbent product made from coconut shells by heating to high temperatures without access to air. The essence of activation is to open the maximum possible number of pores on the carbon-containing material (in our case, the shell) to obtain high degree absorption.

In addition to the total number, the size of the micropores is also important, on which the ability of coal to absorb certain molecules of harmful substances depends - small molecules easily pass through large pores. In this indicator, coconut charcoal is superior to birch charcoal and, even more so, pharmaceutical charcoal.

Appearance

Attention! Use only activated coconut carbon of the KAU-A brand, since the same for hookahs and other filter systems may contain impurities and additives that will end up in the alcohol.

Advantages of coconut charcoal for purifying moonshine over birch and pharmaceutical charcoal:

• has more smaller micropores, which increases filtration efficiency, absorbs up to 80% of essential oils and up to 90% of esters;
• savings - for 1 liter of distillate with a strength of 40 degrees you need 10 grams of coconut charcoal, and this is 5 times less than birch charcoal;
• It collects little dust, which makes it easy to clean the drink from the coal itself.

The use of activated carbon is not always intended to cleanse the drink of harmful impurities. For example, even with the same strength, vodka is more pleasant than alcohol diluted with water - it does not “burn” the oral cavity as much and has a milder taste. Moreover, after rectification, there are no impurities left in the alcohol that coal can remove.

Another effect occurs - partial oxidation of aldehydes contained in alcohol to acids under the influence of air remaining in the pores of the coal. As a result, esters are formed that soften the taste. It is difficult to achieve minor oxidation of aldehydes by other methods, which is why in distilleries the sorting (a mixture of water and alcohol) is passed through coal.

Technology for purifying moonshine with coconut charcoal

Purify only sugar and grain distillates, since in addition to harmful substances, molecules responsible for the aroma and taste of fruit moonshine remain in the pores. As a result, the smell of apples, cherries, and other fruits disappears.

Subsequence:

1. Dilute the moonshine with water. If there is a second distillation - up to 18-20%. If re-distillation is not planned - up to 40-50%. The lower the strength, the higher the degree of purification, since the molecular bond is weaker.
2. Grind the coal into pieces 1-4 cm in size (if the manufacturer has not done so). Sift out the dust.
3. Pour the sifted coal into a glass container, most conveniently into a jar. Proportions – 10 grams of activated coconut charcoal KAU-A (about 2 tablespoons) per 1 liter of moonshine, calculated at a strength of 40 degrees. Excess will not harm, but will not improve the quality of filtration.
4. Stir and seal tightly. Leave for 3-4 days in a dark place at room temperature. Shake the container every 8-12 hours (preferably).
5. Strain the purified moonshine through cheesecloth or a strainer, then filter from remaining coal through cotton wool or a coffee filter.
6. The finished distillate must be absolutely transparent. Make a fractional distillation (I recommend) or simply bottle it for storage.

An alternative cleaning method is to pass the moonshine 2-3 times through a column (you can make a homemade one), but the effect is somewhat worse than when infused

Often, coconut coal producers, in pursuit of profit, achieve low production costs of coal and trust their production to small companies, where there is virtually no industrial labor, but exclusively manual labor. Unfortunately, this leads to the fact that the quality of even one batch of goods can differ radically from each other.

Premium coal is produced in modern factories with a closed automated cycle, where manual labor is minimized and, accordingly, the human factor does not affect the quality of the product. Compliance with high technologies allows all subsequent batches of goods to be made with the same quality, so as not to lose the trust of their fans and regular customers.

Cocobrico charcoal is a 100% natural charcoal made from coconut shells.

What is the difference between coconut charcoal for hookah and charcoal for hookah?

For true hookah lovers, for those who work in hookah establishments and hookah connoisseurs, quality coal is always of significant importance. It is no wonder that the characteristics of coal directly affect the ease of use, the duration of combustion, heat transfer, the taste and smell of smoke released when lighting coal and the smell released when smoking a hookah. Therefore, experts in the hookah business always give preference to natural coals, which include charcoal, and we especially pay attention to coconut charcoal for hookah. It is thanks to their remarkable quality that a good hookah can be prepared. When using a natural product such as charcoal, you will never experience an unpleasant aftertaste. But he is far from the present coconut charcoal for hookah - the quality characteristics of the latter are much better than those of its woody counterpart.

What is coconut charcoal for hookah?

coconut charcoal– a real innovative find. A special technology for processing coconut shells makes it possible to achieve high heat transfer rates and prolonged smoldering. coconut charcoal It is made in the form of a cushion, which is very practical - it does not roll off the cup and greatly facilitates the lighting process. It also leaves little ash behind.

Only real coconut charcoal, made from exotic coconut shavings, can satisfy the high demands of avid hookah lovers. This type of coal is completely devoid of smoke and odor, and only during the process of smoking tobacco does it subtly add an exotic aroma.

Separately, it is worth mentioning the significant efficiency of coconut coal - its combustion lasts several times longer than other hookah coals. When ignited, it does not spark, which is important for closed premises.

Coconut charcoal for hookah successfully increases the army of its fans. If you have not yet appreciated his wonderful qualities, hurry up and do so soon. Our store will help you fulfill your aesthetic and practical aspirations.

Types of coal for hookahs can be roughly divided into two groups. The first group includes natural charcoals for hookahs, which require heating on a flame or electric stove. For other types of hookah coals, special ones are produced turbo lighters or gas-burners

The main advantages of coconut charcoal:

• burning time up to 1 hour 20 minutes;
• a large amount of heat generated;
• small amount of ash;
• practically no odor when igniting;
• high quality compact packaging.

Cocobrico coal environmentally friendly premium class coal. Produced in Indonesia. Cocobrico Currently in Russia it is the most popular coal for hookah, both in hookah establishments and among private hookah lovers.

Coal is supplied to Russia in two packages - 1 kg and 250 g. The package contains cubes of equal size (96 - in a large one, 108 - in a large one, 24 - in a small one). Thanks to this, Cocobrico does not need to be additionally “broken” before ignition, as previously had to be done with other brands of hookah coal. The coal cubes are very dense and do not crumble when lit or smoked. After full heating, Cocobrico charcoal does not emit any foreign odors and provides uniform heat throughout the entire smoking period.rnrnThanks to the special production technology, Cocobrico leaves behind very little ash, which is especially convenient when using. For smoking on a standard 16-gram cup, 2-3 cubes of coal are enough, and the 3rd cube should be used on such a cup only 20-25 minutes after the start of smoking. These 3 cubes will be enough to completely smoke a cup of standard Fakher hookah tobacco in 1 hour 20 minutes.

Coconut charcoal has a large adsorption capacity and a narrow particle size distribution.

Of course, not the one intended for lighting a hookah, but still

coconut charcoal, used in balloon-type sorption filters, as well as cartridge filters. Filters of this type are used for “final” water purification - improving the organoleptic qualities of water (reducing turbidity, odor), and also as “interceptors” of oxidizing agents used at earlier stages of water treatment.

Coal 207C is used:

• for drinking water purification
• for removal of organochlorines, ozone, trihalomethanes
• for purifying vodka
• for water purification in technological processes
• for industrial wastewater treatment
• for air purification and ventilation emissions
• for recovery of low molecular weight solvents.

Production and composition of hookah coal

The principle of making material for lighting chilim is very simple: the raw material is ground until a homogeneous consistency is obtained, then it is dried in a special chamber under high temperature. The resulting product is mixed with a binder and compressed. A portion of saltpeter or dry alcohol is added to self-igniting coal. Coal is usually shaped into small cubes.

Raw materials used in production

The characteristics of the finished product largely depend on the quality of the raw materials. Manufacturers producing hookah charcoal may add the following ingredients to the product:

• Coconut shell;
• Dried grapevine;
• Olive fruit pits;
• Walnut shells.

A separate variety is the so-called. “self-igniting” coal, which is shaped into tablets. In addition to the coal chips and binder, this product contains a flammable ingredient.

Self-igniting charcoal is often used when smoking hookahs outdoors. However, it should be noted that this material has significant disadvantages. First, sparks and smoke are produced during the initial ignition. Secondly, during smoking, a distinct taste of saltpeter is felt, which spoils the aroma of the tobacco mixture.

Coal shape

Modern production of hookah coal can offer consumers products of various shapes - in the form of pyramids, blocks, square pieces. Coal is produced in the form of tablets, and even triangular bars. There are silver-plated coals that allow the hookah maker to avoid getting his hands dirty. The shape of the coal does not affect the burn time or other characteristics of the material.

Kokobriko coal made from natural coconut shells, produced in the form of cubes, is in stable consumer demand. It has the following advantages:

• Quite fast ignition time;
• No foreign taste or smell;
• Long burning;
• Competitive price.

To light a tobacco mixture in a large cup, 2-3 cubes of Cocobrico charcoal are enough. If you cover the coal with a cap, the burning time reaches 50 minutes (without a cap - up to 1.5 hours).

What is coconut charcoal for and how is it made?

Coal obtained from coconut shells is used in various industries human activity due to its unique properties. Its production can be carried out in many ways, but the most popular is for industrial applications is a pyrolysis method - combustion in special charcoal kilns at high temperatures (up to 1000°C) without air access.

If air access is not limited, oxygen can lead to shell destruction. To obtain a high-quality sorbent, completely dried, clean and natural coconut shells are used.

After heat treatment the material is crushed using special equipment to form various fractions. This method makes it possible to obtain an environmentally friendly microporous sorbent from sustainable natural resources, which does not emit toxic gases when burned, which makes it safe to use in various industries (culinary, metallurgical industries).

Areas of use

The drug is actively used for purification, separation and extraction of various substances in industry and medicine. The material is also needed as fuel for cooking, as it is odorless and does not change the taste of food. Can also be used for cleansing alcoholic drinks from fusel oils. Coconut-based charcoal makes these products safe by removing harmful tanning components, and also absolutely transparent.

In addition, the use of sorbent in the production of alcoholic beverages allows the oxidation process to be accelerated, thereby reducing the aging period. Also, when reacting with alcohol, esters are formed, which improve the taste and aroma characteristics of alcoholic products.

Activated carbon is used in winemaking and brewing, as well as for the preparation of stronger long-aging drinks (whisky, cognac, moonshine, etc.). It is used in the production of tobacco products (cigarettes with a carbon filter) and as a load in household and industrial filters to purify water from chlorine, its compounds and residual oxidizing agents. Activated material is not suitable for hookah; for this purpose, a sorbent that has not undergone activation should be used.

In addition, the drug is used for:

• Water treatment (industrial water, municipal water supply, swimming pools).
• Production of alcoholic beverages (beer, wine, spirits), purification from fusel oils.
• Extraction of gold and other metals from solutions and pulps.
• Production of tobacco products.
• Adjustments of smells and tastes in Food Industry.
• Chemical industry, etc.

General concepts about activated carbons

The most common filter material for purifying water, fats and alcohols is activated carbon. Activated carbons are fine carbon particles up to 5 mm with a developed system of internal pores and channels up to 20 angstroms in size. Granular activated carbons are made from the following bases:

• Wood base;
• Coal base;
• Polymer artificial fibers;
• Coconut shell.

The production process of any activated carbon involves pyrolysis of the base. Pyrolysis is the heating of a material by high temperature up to 1000 degrees Celsius in the absence of oxygen. The coals from the wood base are activated and treated with hot steam. Charcoal characterized by high capacity but low mechanical strength. Coal-based coals have higher mechanical properties, but do not remove the entire spectrum of organic compounds.

A special group is represented by granularcoconut activated carbons . From the name it is clear that they are made from coconut shells. Widely in demand in the food industry and in production where clean water is required. Produced in India, Thailand and Germany, China. Coconut shell coals do not have the disadvantages that charcoal and coal coals have.Coconut activated carbonhas low abrasion and grindability and high absorption capacity. The high strength of coals, that is, low abrasion and grindability, is the main parameter when choosing coals for purifying water and alcohols.

Scope of application of activated carbons

Coconut activated carbons molecules of organic substances and residual chlorine are effectively removed from aqueous solutions. Suspended fine particles of any nature. Colloidal particles are removed due to dead-end internal pores, in contrast to aluminosilicate loads that have an inlet and outlet channel in the volume of the granule. Phenols, aromatic hydrocarbons, petroleum products, organophosphorus compounds, fusel oils, alcohols, chlorine, and surfactants are well removed. Coconut activated carbons decompose residual active chlorine and ozone. Widely used at the end of the water treatment chain when using chlorine and ozone as an oxidizing agent. Activated carbons, as a rule, do not regenerate due to dead-end channels, and after use they must be replaced after a year of operation. The ability to remove the listed chemical compounds allows the use of activated coconut carbons in the following areas:

• Cleaning of alcoholic beverages;
• Clarification and deodorization of edible oils and fats;
• Discoloration of sugar syrups;
• Drinking water purification;
• Water preparation in food production;
• Industrial wastewater treatment;
• Destructors of ozone and chlorine after the introduction of an oxidizing agent;
• Charcoalization;
• Pharmaceuticals;
• Gold mining.
