Abstract

The invention provides a method and a device for reliably introducing a gas, preferably CO2, into a liquid which, for example, contains water, by feeding the gas to the flowing liquid and introducing it into the flow.

Description

The invention relates to a method for introducing gas, preferably CO ₂ , into a liquid.

The invention also relates to an arrangement for introducing gas, preferably CO ₂ , into a liquid.

Beverages, especially water and mineral water, but also soft drinks such as lemonade, fruit juices and liquids with other flavors are often carbo nized, ie with CO ₂ (carbon dioxide) added to create the currently popular impression of "freshness". A CO ₂ addition can also improve stale or stale water or water with disinfectants. Therefore, water (with or without minerals) in bottles or other containers with CO _{2 is} added, which is introduced under pressure into the liquids and z. B. is released by so-called CO ₂ cartridges. Buying bottled water with CO ₂ is cumbersome and expensive because of the transportation. The self-production is also cumbersome because the CO ₂ gas must be introduced into the water in pressure vessels, which then remains under pressure in the vessels.

The object on which the invention is based is to be able to easily and continuously produce liquids containing CO ₂ , in particular water, the CO ₂ consumption being based on the amount of water supplied and drawn off.

The solution according to the invention is that the gas of the flowing liquid and introduced into this becomes.  

A further embodiment of the invention which improves the uptake of CO ₂ and which has an independent inventive rank is that the gas is introduced into the inflow region of a Venturi tube through which the liquid flows.

The uptake of CO _{2 can} also be improved by a further embodiment of the invention, which also has an independent inventive rank. This further training is that the liquid is cooled before reaching the introduction point of the gas.

The CO ₂ gas is under a certain pressure in order to be able to get from and into the liquid from a storage container. So that the gas does not get into the supply line, in a further embodiment of the invention, which also has its own inventive rank, a backflow preventer, for. B. a check valve is provided, which is flowed through by the liquid in the flow direction according to normal operation. In the opposite direction, gas and / or liquid cannot flow through, so that the supply line cannot be struck by gas if the liquid supply fails.

In the flow path of the liquid and the gas is according to the Invention vorese preferably a stationary mixing arrangement hen, in the gas and liquid in close contact with each other to be brought. The gas can end up through a nozzle Feed line can be led into the liquid. The pressure of the gas and its throughput rate (gas quantity / unit of time) in a further embodiment of the invention at least approximately are kept constant, e.g. B. the pressure by a pressure min of those.

It is within the scope of the invention, the liquid before or after the CO ₂ supply additives, for. B. flavors or disinfectants. In a further embodiment of the invention, the carbonized liquid can flow through a reaction path in the form of a reaction line which is matched to the reaction time of gas and liquid.

The preferred liquid which can be treated according to the invention, ie can be mixed with CO ₂ , is water, preferably tap water. The carbonized liquid can advantageously be supplied to a mixer tap which has a further water tap for normal cold water not enriched with CO ₂ and optionally a tap for hot water.

According to a development of the invention, which also has a constant inventive rank, a mass flow of water enriched with CO ₂ can be mixed with a mass flow of non-enriched water, the flow of one of these components being adjustable. This makes it possible to set the degree of carbonization in the mass flow of the water enriched with CO _{2 in} advance. The size of the total stream, which is formed by mixing the streams of CO ₂ -enriched water and unenriched water, can also be controlled according to this development.

According to an important further development of the invention, which relates to a very advantageous use of liquid enriched with a gas, in particular carbonated water, and which has an independent inventive step, plants can be supplied with liquid enriched with a gas, preferably by spraying. In this case, water enriched with CO ₂ can advantageously be added. The generation of CO ₂ -enriched water can be carried out continuously using one or more of the above-mentioned method steps and the construction elements listed above and below in the same or similar manner. The use of carbonated water in different ways and with different components is also possible. It was found that the plants when used, e.g. B. spraying, carbonated water thrive significantly better Lich.

According to a further important embodiment of the invention, which relates to a further very advantageous use of liquid enriched with a gas, in particular carbonated water, and which has an independent inventive rank, liquid enriched with a gas can be supplied to a fabric (also carpet) for cleaning it the liquid is removed after an exposure time together with removed dirt. The fabrics that can be treated are in particular textile fabrics including carpets. For the treatment, water enriched with CO ₂ gas (carbonized water) is advantageously sprayed onto the tissue under excess pressure and suctioned off after the exposure time. The continuously flowing, z. B. from a container of water can be continuously enriched with CO ₂ gas and sucked off after the exposure time in a dirty water tank. The generation of CO ₂ -enriched water can be carried out continuously using one or more of the components mentioned above and below and with the above-mentioned method steps in the same or similar manner. However, the use of carbonated water in different ways for the same purpose is also possible. It was found that a good cleaning effect can be achieved by the process according to the invention.

The arrangement mentioned at the outset is characterized by a Supply of the gas to the flowing liquid and through the introduction of the gas into the flowing liquid.

According to an advantageous development of the invention, the independent inventive rank is located Point of introduction of the gas in the inflow area of a venturi Tube.  

Another advantageous embodiment of the invention, the independent inventive rank also exists in that upstream from the point of introduction of the gas in the flow path of the liquid, a backflow preventer, ins special a check valve, which is arranged in the operational flow direction opposite direction essentially impermeable to gas and / or liquid is.

Another advantageous implementation of the inven tion, which also has independent inventive step, is characterized by an upstream of the point of introduction of the gas arranged cooling device for the liquid speed. Such cooling is very advantageous because cooled liquids can absorb more CO ₂ than uncooled ones. The cooling device can advantageously be formed as a continuous cooler.

The good vermi is of particular importance for the invention generation of gas and liquid, according to a preferred Further training in a mixed arrangement downstream of the inlet tation point of the gas into the liquid takes place. The Mixing arrangement advantageously has at least two stationary Mixing elements that are in pipes. These pipes are preferably made of VA steel or plastic; your Diameters suitably correspond to the diameters of the rest pipelines. The mixing elements contain e.g. B. slats or webs for guiding the liquid and gas in intensive mixing. The second mixing element is opposite the first mixing element is preferably twisted in the tube net, e.g. B. 90 °. To introduce the gas into the flowing Liquid at the beginning of the venturi tube can be according to the inven serve a nozzle.

In a further embodiment of the invention, a pressure container in the form of a pressure bottle or a pressure tank is used to hold the gas, in particular the CO ₂ gas, which are easily designed and arranged to be exchangeable. It is expedient for a quick exchange of the pressure bottle, a quick-connect connection between a valve closing the pressure bottle and a gas-forwarding line hen, for example in the form of a bayonet fitting. The pressure bottle can usefully have a small, handy format, for example for attachment under a sink.

A pressure regulator, e.g. B. in the form a pressure reducer, or a gas flow regulator. Last one rer can the amount of gas per unit of time according to the through regulate the rate of the flowing liquid to be carbonized.

In addition to the gas CO ₂ , other additives can be added to the liquid, e.g. B. flavors, such as for making lemonades or disinfectants, which are advantageously metered by means of a metering arrangement, for example in dependence on the flow of liquid.

Downstream of the point of introduction of the gas and preferably downstream of the mixing arrangement can be a reaction line be arranged in which liquid and gas react with each other can greed.

The liquid is preferably tap water, in particular Household tap water. In this case, it is special partial if one or more components for the gas and Liquid supply (cooling device, venturi tube, mixing arrangement tion, gas tank and the like) separately or together can be removed and reattached.

The carbonated water is advantageously one in households Mixer tap feedable, which according to a further embodiment form of the invention additionally a tap for cold and / or has warm water. Details of training the Mixer tap and water supply are German Patent application 198 06 243.5 dated 16.02.1998.  

According to a further embodiment of the invention, which also has an independent inventive rank, a pressure reducer and / or an overpressure-limiting pressure relief valve can be provided in the line for the CO ₂ -enriched water.

According to a further embodiment of the invention, which also has an independent inventive rank, a mixing device can be provided for a CO ₂ -enriched and for an unenriched flow of liquid, at least one flow being adjustable in size. The total flow, which is formed by the two mixed flows, can also be controllable by a special control arrangement. This has the advantage that the content of CO ₂ -containing water can be predetermined, largely independently of the total amount of water which can also be controlled.

The pipelines and components arranged in them can made of carbon-resistant plastic and / or noble steel exist.

An important further development of the invention, which relates to a very advantageous use of liquid enriched with a gas, in particular carbonated water, and which has an independent inventive rank, is characterized by a feed line for plants enriched with gas. The liquid water and the gas CO _{2 are} advantageous. The mixture is sprayed onto the plants under positive pressure using a spray head and allows them to thrive better. The generation of carbonated water can be carried out continuously using one or more of the above-mentioned components and in the same or similar manner. The use of carbonated water generated in different ways is also within the scope of the invention.

Another important embodiment of the invention, which relates to a further very advantageous use of liquid enriched with a gas, in particular carbonated water, and which has an independent inventive rank, is characterized by a feed line for liquid enriched with a gas to a tissue its cleaning and through a drain for the dirt-containing liquid speed. The fabrics that can be treated are in particular textile fabrics including carpets. For the treatment, the liquid speed, preferably carbonated water, is supplied under excess pressure and suctioned off after an exposure time. The water can be continuously removed from a container for fresh water or a pipe. CO ₂ can be introduced into the water with a continuously working introduction device for CO ₂ . At the end of the supply line there can be a spray head for spraying the enriched water onto the fabric or carpet. A suction device is used to remove the liquid containing dirt. According to a further embodiment of the invention, a container for extracted dirt containing liquid can be provided. The arrangement of the fresh water tank, the inlet device for CO ₂ , the feed line, the drain, the suction device and the dirty water tank on a mobile frame is very advantageous. The carbonated water can be generated continuously using one or more of the aforementioned components and in the same or similar manner. However, the use of carbonated water produced in different ways is also possible. It has been shown that this type of supply of carbonated water to fabrics, including carpets, leads to good cleaning effects.

The invention is not limited to the carbonation of tap water, mineral water, lemonades or other soft drinks. In principle, alcoholic beverages such as beers, wines or similar beverages can also be enriched with CO ₂ . In addition, it is also possible with the invention to add other gases to other liquids.

The advantage of the invention is that when a liquid is withdrawn at a tap, especially in households, an enrichment with CO ₂ gas is automatically possible for the production of refreshing beverages. There is no need to buy expensive water bottles or to transport the heavy bottles back and forth to and from the beverage suppliers. If a network contains inferior water, this can be improved with the invention and thereby upgraded.

The cost of the new mixer tap including the fittings for a CO ₂ gas bottle is slightly higher than a conventional mixer tap for tapping cold and hot water alone. Installation is straightforward, about as time-consuming as a conventional mixer tap. The new system takes up little space and can therefore be installed under almost any sink. Special pressure vessels for the CO ₂ -enriched water, pumps etc. are not required. Cold, warm and CO ₂ enriched water can be drawn from a tap. The mixer tap contains a safety valve that also serves as a tap valve for water enriched with CO ₂ . The mixing process and the valve are precisely matched to one another and are designed so that the flow rate and pressure cannot be changed by the end user. With the invention, a water heavily enriched with CO ₂ (soda water) can be offered. However, this mixture can be changed in terms of taste by the consumer by adding water without adding CO ₂ by opening the normal water inlet. The CO ₂ bottle is sufficient for a correspondingly higher tap quantity of soda water with a lower CO ₂ addition. With the newly developed system, the production of CO ₂ -enriched water is much cheaper than purchased water. The user also saves dragging and storing bought bottle crates.

The invention is illustrated by means of exemplary embodiments explained. Show it:

Fig. 1 shows a plant for enriching water with CO ₂ (carbon dioxide), which is suitable in particular for households,

Fig. 2 is a mixing chamber for adjusting the degree of water approximately Karbonisie,

Fig. 3 shows an application for carbonated water for cleaning cleaning fabrics including carpets

Fig. 4 shows another application for carbonated water for the application of plants and

Fig. 5 is a sketch of a circuit for pressureless water heating.

In Fig. 1 flows through a line ( 1 ) for supplying cold water, the water according to the arrow ( 2 ) through a cooling device ( 3 ) which is designed as a known continuous cooler ( 4 ). From the once-through cooler ( 4 ), the ge cooled water flows according to arrow ( 2 ) to a Rückflußverhin derer ( 6 ), which is expediently designed as a check valve and prevents the supplied CO ₂ gas from entering the water supply network, not shown. At an introduction point ( 8 ), CO ₂ gas that emerges from a supply line ( 11 ) is passed into the liquid. A nozzle ( 9 ) can be used. The introduction point ( 8 ) is in the input area of a Venturi tube ( 12 ), in which there is a narrow point ( 13 ) through which the liquid flows at an increased speed. The CO ₂ gas is from a pressure bottle ( 15 ) via the supply line ( 11 ) and a Regelanord voltage for gas pressure or gas flow (quantity / Zeitein unit) according to arrow ( 10 ) leads to the point of introduction ( 8 ). The gas pressure can be kept at a substantially constant value in a simple manner by means of a pressure-stabilizing pressure reducer ( 14 ). If a flow controller known per se is used, the amount of gas per unit time can advantageously be adapted to the amount of liquid flow (amount of liquid per unit of time).

Following the Venturi tube ( 12 ), there is a stationary mixer arrangement ( 16 ) in the flow path of the liquid and the CO ₂ gas, which has at least one mixing element ( 17 ), but preferably two mixing elements ( 17 , 18 ), which at least for the most part consist of corrosion-resistant material, preferably plastic.

The mixing elements ( 17 , 18 ) have wavy baffles and / or webs for the water and the CO ₂ and are connected to a rod in the mixing tubes by means of supports.

Two mixing elements ( 17 , 18 ) (tubes) arranged one behind the other are advantageously rotated by 90 ° with respect to the position of their guide surfaces and / or webs. Their baffles accelerate the water in different directions, creating a very intensive and homogeneous mixture of liquid and gas. Mixing elements of the type described are known per se and z. B. from the company Sulzer Chemtech GmbH, Usingerstr. 114, D-61239 Ober-Mörlen sold under the type designation SMV mixing elements, SMX mixing elements and SMXL mixing elements.

A line section ( 19 ) adjoins the mixing arrangement ( 16 ) and serves as a reaction path ( 21 ). Then the water mixed with CO ₂ reaches a mixer tap ( 22 ) which, in addition to the feed line ( 1 ), can also have further feed lines ( 23 , 24 ) for cold or warm water and an outlet ( 29 ). Cold water can be branched off from line ( 1 ) at the branch ( 31 ) and fed to the mixer tap ( 22 ) via a line ( 32 ) to the cold water supply line ( 23 ). A pressure reducer ( 33 ) is arranged upstream from ( 31 ), which reduces the pressure of the tap water (e.g. 4 bar) to a pressure (e.g. 2.8 bar) which is reduced by a certain amount (e.g. 1 bar) is below the pressure (eg 3.8 bar) to which the pressure reducer ( 14 ) reduces the CO ₂ pressure from the gas bottle ( 15 ).

However, it is also possible to provide the mixer tap with a changeover switch (not shown), with which it can be switched from one operating mode in which carbonated water can be drawn off to another operating mode in which no concentrated water is drawn off. The additional cold and hot water can be removed using a one-hand lever ( 26 ). A special tap ( 27 ) for valve actuation is used to remove the carbonated water. Further details of the mixer tap can be found in the aforementioned German patent application 198 06 243.5 from February 16, 1998. At an input point ( 28 ) additives can be introduced into the water, advantageously metered, via a line ( 20 ). It can be flavorings, e.g. B. for lemonade production, or act as disinfectants for the treatment of water containing dangerous germs.

The tap ( 27 ) can act on a valve, not shown, which, in addition to its control function for the flow of carbonated water, forms a pressure relief valve. This allows pressures in the line ( 1 , 19 ) to be reduced to the outside by releasing CO ₂ and / or water. A valve seat acted upon by the tap ( 27 ) can be designed as such a pressure relief valve, which opens when the pressure in the line ( 15 ) increases significantly in the direction of an environment into the interior of the mixer tap ( 22 ).

The pipes ( 1 , 19 ), the nozzle ( 9 ), the mixing elements ( 17 , 18 ) and the other components which come into contact with the carbonic acid are advantageously protected against the aggressive water-CO ₂ mixture in that they consist of a VA steel, which can still be lined with a durable plastic. They can also consist of a plastic that is resistant to carbon dioxide.

Leave one or more components of the system described arrange themselves so that they can be used individually or together in simple Can be removed and reinstalled for maintenance purposes nen. Details of this are also the German patent registration 198 06 243.5 dated 16.02.1998.

The system for CO ₂ water enrichment works as follows:
If the tap ( 27 ) is opened, the water cooled in the cooling device ( 3 ) begins to flow into the line ( 1 ). The cooling capacity of the water for CO _{2 is} significantly increased by cooling. In addition, consumers generally find cooling the water pleasant. As a result of the water flowing and its increased speed in the venturi tube ( 12 , 13 ), which is associated with a drop in pressure, CO ₂ gas flows through the supply line ( 11 ) and into the cooled water. After thorough mixing in the mixing arrangement ( 16 ) with the mixing elements ( 17 ) and ( 18 ) and the flow through the reaction zone ( 21 ), the carbonized water can emerge from the outlet ( 29 ) of the mixer tap ( 22 ). Optionally, the water on line ( 20 ) can be enriched with additives, in particular flavors. Before the Venturi tube ( 12 , 13 ), a nozzle ( 9 ) can be arranged in the flow direction, through which the water enriched with CO _{2 is} accelerated in the direction of the Venturi tube.

In Fig. 1, the tap ( 27 ) and the associated (not shown) valve can be designed so that it is only open or closed. The degree of carbonization of the water is then largely constant. This constant volume flow with constant degree of carbonation is non-carbonized tap water mixed so that the resulting total stream contains the desired degree of carbonization, for example little, medium or high carbonization.

In addition to this most important embodiment of the invention, an embodiment is also conceivable in which the gas valve (not shown) can be opened and closed continuously by means of a tap ( 27 ), then the quantity flow of the withdrawn water changes and thereby also the amount of the dissolved CO ₂ , i.e. the degree of carbonization.

Fig. 2 shows a variant of the invention, in which the degree of bonization can be adjusted. For this purpose, a controllable valve ( 34 ) is arranged in the line ( 1 ), with which the flow of CO ₂ -enriched water can be adjusted. In a mixing chamber ( 36 ) the non-enriched water flow supplied through line ( 23 ) and the enriched water flow supplied through line ( 1 ) are then mixed by union. The mixed water flow reaches the outlet ( 29 ) via a main flow valve (e.g. a one-hand lever) ( 26 ). In this variant of the invention, the desired degree of carbonization at the valve ( 34 ), the desired amount per unit of time (flow rate) can be set on the one-hand lever ( 26 ).

In Fig. 5, a circuit is shown in which the warm water is produced without pressure in a water heater (60). For this purpose, cold water is controlled by a mixer tap 22 controlled cold water line 61 in the hot water maker ( 60 ). The water entering the water heater ( 60 ) via the cold water line ( 61 ) presses the warm water in the water heater ( 60 ) through a hot water line ( 62 ) in the direction of the mixer battery ( 22 ) out of the water heater ( 60 ). This hot water flowing in from the hot water pipe ( 62 ) emerges from the outlet ( 29 ) of the mixer tap ( 22 ).

In addition, the mixer tap ( 22 ) still has a Kaltwas serzuleitung ( 23 ) which is connected via a corner valve ( 63 ) with a water network, not shown. This Kaltwasserlei device ( 23 ) is removed by a corresponding setting of a hand lever ( 26 ), the cold water that emerges from the outlet ( 29 ).

In the flow direction behind the corner valve ( 63 ), the branching ( 31 ) is provided, through which cold water is removed for the purpose of mixing with CO ₂ . This branch ( 31 ) is connected to the line ( 1 ) which opens into the mixer tap ( 22 ). Behind the branch ( 31 ) is in the direction of flow, the backflow preventer ( 6 ). Behind this, the introduction point ( 8 ) is provided in the flow direction of the cold water, at which the CO ₂ taken from the pressure bottle ( 15 ) is mixed into the water flow flowing through the line ( 1 ). This introduction point ( 8 ) is designed as a feed T-piece ( 64 ). The cold water flows through the crossbar of the T-piece ( 64 ) in the direction of the mixer battery ( 22 ) and passes through the mixing elements ( 17 , 18 ), which are designed as static mixers. The pressure bottle ( 15 ) is connected to the pressure reducer ( 14 ) on the longitudinal bar ( 65 ) of the T-piece ( 64 ) running perpendicular to the crossbar. The pressure bottle ( 15 ) formed as a small, handy bottle is connected to the pressure reducer ( 14 ) via a quick-release fastener ( 66 ). This quick-release fastener ( 66 ) can be designed, for example, as a bayonet fastener which favors the rapid replacement of the pressure bottle ( 15 ).

By actuating the special tap ( 27 ), the line ( 1 ) is opened so that a constant water jet which cannot be influenced by the tap ( 27 ) and which is enriched with a constant amount of CO ₂ , which cannot be influenced either exits the outlet ( 29 ). The mixing ratio between the amount of water flowing through the line ( 1 ) after opening the tap ( 27 ) and the amount of CO ₂ is so determined that a highly gas-enriched mixture of carbonated water emerges from the outlet ( 29 ). The amount of CO _{2 is} so determined that the amount of water is saturated by the gas.

Should a lower mixing ratio be desired according to the taste of a consumer, the saturated amount of water can be removed from the supply line ( 23 ) by actuating the one-hand lever ( 26 ) and mixed with the saturated amount of water. For this purpose, a corresponding mixing chamber (not shown) is provided within the mixer tap ( 22 ). In this way, the mixer battery ( 22 ) can be removed more or less water saturated with CO ₂ .

In addition, however, a mixer tap ( 22 ) is also conceivable, which not only cold and warm water, but also more or less highly saturated carbonated water can be removed only by actuating the one-hand lever ( 26 ). For this purpose, the one-hand lever ( 26 ) can be pivoted into a position in which the mixer tap ( 22 ) only releases an outflow of carbonated water. By further pivoting the one-hand lever ( 26 ), the drain can be controlled so that the carbonated amount of water is continuously mixed with a more or less large amount of cold water.

Fig. 3 shows an arrangement for cleaning fabrics including carpets using carbonated, ie by means of CO ₂ -enriched water. It has surprisingly been found that such water has a very good cleaning effect, for. B. in carpets. A tissue, in particular a carpet ( 41 ), is sprayed with water by means of a spray head ( 42 ), which is enriched with CO ₂ and which is supplied by means of a line ( 43 ). For this purpose, fresh water is taken from a fresh water tank ( 44 ) and enriched with CO ₂ in an enrichment device ( 46 ). A pump ( 47 ) is used for removal and delivery to the spray head ( 42 ). The CO ₂ can be supplied from a container ( 15 ) and into the water flowing through the line ( 43 ), possibly through a nozzle ( 9 ). A mixer arrangement ( 16 ) can be used for the intensive mixing of water and CO ₂ gas. With ( 52 ) a motor-driven suction device for the polluted water is indicated schematically. This creates a negative pressure, with the help of which the polluted water is sucked through a suction device ( 49 ) into a dirty water tank ( 51 ), in which the suction device ( 52 ) generates a negative pressure through a suction nozzle ( 57 ). The suction line ( 49 ) has at its end facing away from the dirty water tank ( 51 ) a suction sensor ( 48 ) which is guided over the carpet ( 41 ) and which absorbs the mixture of carbonized water and dirt which has accumulated in this. After cleaning the carpet, the dirty water tank ( 51 ) can be emptied and cleaned via a disposal station (not shown).

The components described are net angeord on a frame which is movable by means of wheels ( 53 ). For Karbonisie tion of the water, if necessary, more of the components described in Fig. 1, at least partially use. So z. B. upstream of the mixing arrangement ( 16 ) the Venturi tube ( 12 ) shown and described in Fig. 1 is arranged. An arrangement for setting the degree of carbonization according to FIG. 2 can also be provided. It is within the scope of the invention to use carbonated water for cleaning fabrics, e.g. B. carpets to use.

Fig. 4 shows an arrangement for the treatment of plants (indicated schematically and designated with position ( 56 )) by means of carbonized, ie by means of water enriched with CO ₂ . The water is supplied through a feed line ( 43 ) and enriched at the gas supply point ( 28 ) with CO ₂ gas, which from a gas container ( 15 ), for. B. a gas bottle and is introduced into the water flowing through the supply line. With ( 12 ) and ( 16 ) is a Venturi nozzle or mixing arrangement be characterized, which have the same function as that with the same Zif remote components of FIG. 1. The water enriched with CO ₂ can be sprayed onto the plant ( 56 ) by means of a spray head ( 42 ). Surprisingly, it has been shown that plants sprayed or burned off with such water thrive better than untreated plants. To carbonize the water, if necessary or before geous, other components described in FIGS. 1 and 2 can be used, for. B. An arrangement for adjusting the degree of carbonization according to FIG. 2. It is within the scope of the invention to use carbonized water in different ways.
