Abstract

When oxygen is passed through an aqueous alkaline electrolyte, in which a voltage is applied across a cathode and an annular anode surrounding the same, said oxygen is activated by interaction with the active oxygen produced on electrolysis by stimulation due to the action of various energy forms which occur on passing a current through the electrolysis device (18) (in particular, sound energy and light energy). The active oxygen is stabilised in water clathrates and said moist gas mixture is brought into contact with the liquid for enrichment with oxygen in a counter-current column (1), whereby the liquid for enrichment flows down the counter-current column (1), with a silicate-containing material as packing (1a) and the activated oxygen flows up the counter-current column (1). The liquid for enrichment is optionally passed several times through the column (1) until the desired degree of enrichment with oxygen is achieved.

Description

The invention relates to a method for producing water with increased oxygen content, including its activated forms, having the features of the introductory part of claim 1.

The invention further relates to an apparatus for carrying out the method for producing water with increased oxygen content, including its activated forms.

Many biological processes require oxygen, and the prerequisite for the introduction of oxygen into these processes is that the oxygen is activated beforehand. In nature, the enrichment of water by oxygen is slow, which in turn causes a rapid exhaustion of the oxygen reserves in case of contamination of the system, even if it is aerated before a biological purification of the water. The biological processes would be more efficient if high levels of oxygen were retained in the water for a long time under normal pressure and temperature conditions, and if there were conditions for its activation.

Recently, the positive effects of drinking water with increased oxygen content have been reported. It has been argued that the consumption of oxygen-saturated water leads to increased levels of oxygen in the blood, a decrease in heart rate, improved digestion, and other positive changes in health, which has to do with the fact that the sour- improve the tissue care. The use of oxygen-saturated water in livestock and poultry farming should reduce morbidity and mortality and increase weight gain. The introduction of water with increased oxygen content in contaminated water should accelerate its self-cleaning.

Manufacturers of oxygen-saturated water claim that it compensates for an oxygen deficit associated with the decrease in oxygen content in air. But a review shows that, no matter how much it may be oxygenated or even saturated, water can not compensate for lack of oxygen. Man and many animals breathe with lungs, through which the oxygen reaches the blood extremely quickly and efficiently, u.zw. at a speed of up to 5 l / min. The gastrointestinal tract does not have such properties. Therefore, it can not compensate for a lack of oxygen in the air, even if such exists, no matter how much oxygen enters the organism with the water. In addition, even when water has been supersaturated with oxygen 10 times, the concentration of oxygen in one liter of water will not exceed the value of 90 mg, which is just over 0.1 l of free oxygen or 0.5 l more common Air corresponds. Nevertheless, there are reports of a positive effect of oxygen-enriched water and that it has special properties.

Various methods and devices have been proposed in the art for obtaining water enriched with oxygen.

Also known are forms of work with active oxygen, including singlet oxygen, i. with excited form of molecular oxygen.

US Pat. No. 4,549,969 A describes a process for increasing the oxygen content in aquarium water. A hollow rod is introduced into the aquarium, in which an aqueous solution of hydroperoxide (its concentration is in the range of 0.1-5%) is included. The rod part immersed in the container with the oxygenating water has pores. The outer surface of the rod member is covered with a substance which catalyzes the decomposition of hydroperoxide in water and in oxygen: manganese dioxide, Fe ₂ O ₃ , nickel oxide. Oxygen produced in the aquarium dissolves better in the water than would be the case if pure oxygen were added to the water. In this known method, oxygen is supplied "in statu nascendi". This active type of oxygen (singular acid) can saturate water better than non-stimulated oxygen. Singlet oxygen is an excited form of molecular oxygen (O ₂ ), which in turn represents the usual form of oxygen found in the air or in water, and is also called triplet oxygen. Singlet oxygen forms in a series of chemical reactions involving, for example, oxygen radicals and peroxy compounds. However, singlet oxygen also arises from ordinary tri- Oxygen in contact with special colors, so-called photody- namic colors, with light of a certain wavelength. In contrast to triplet oxygen, the singlet oxygen is a strong oxidant and readily enters into various chemical reactions, especially with water. Singlet oxygen (= singlet oxygen) is not oxygen that is atomic (an atom of oxygen), but is derived from the quantum physical description of the state of the electrons in individual oxygen molecules.

JP 1228591 A describes a method in which air is irradiated intensively with ultraviolet radiation in the wavelength ranges from 150 nm to 180 nm and from 200 nm to 300 nm. The irradiation in these wavelength ranges contributes to the formation of ozone in the oxygen contained in the air. Ozone splits instantly, forming atomic oxygen. The oxygen thus formed is introduced into water, which is intended to become active.

DE 198 55 881 C describes a process for the activation of water and the use of activated water, which is said to be highly active by introducing singlet oxygen. Oxygen activation is by light irradiation using a "photodynamic effect". The essence of the effect is that certain synthetic dyes can be excited triplet by illumination in the range of wavelengths well absorbed by each dye. The excitation can be transferred to a triplet molecule of oxygen, which transitions this molecule into the singlet state.

The disadvantage of these methods is the activation of the oxygen in the air, which also contains nitrogen and carbon dioxide. If active oxygen in the air occurs, side reactions are not ruled out, which can lead to toxic nitrogen, carbon and sour- ter compounds. In addition, the photodynamic colors used in DE 198 55 881 C can degrade in interaction with the active oxygen. The colors, both in their initial form and as products of their degradation, can enter the water and change their consumer properties in an unpredictable way. Finally, with the aid of these methods of water activation, whereby singlet oxygen obtained either by UV irradiation of the air or by irradiation of photodynamic dyes in air or water is introduced into the water, no substantial increase in the molecular oxygen content in the water can be achieved. However, since the singlet oxygen is short-lived, the active water will rapidly lose its particular properties if there is no excess of molecular oxygen in the water.

The prerequisite for long-term stopping of the particular properties of the active water is that both active oxygen is introduced into it, not only in the form of singlet oxygen, but also in its other active forms, such as the hydroperoxide radical, the ozone, higher peroxides of the types H ₂ O ₃ and H ₂ O ₄ and their radical forms and other oxygen species, as well as the fact that a significantly increased, relatively balanced concentration of molecular oxygen is produced in the water, which activates in the decay reactions of these high energy particles becomes, whereby they are reproduced.

Other known methods and apparatuses for saturating liquids (e.g., water) with oxygen on an industrial scale are directed to the supply of liquid to an oxygen medium which is under pressure in a closed container. (US 5,766,490 A.

This method and the apparatuses allow to obtain water with a content of 50-60 mg oxygen / liter. The disadvantages of this method are that the content of oxygen is expensive and that it drops rapidly during storage under normal conditions.

Many biological processes require oxygen. The saturation of natural water with oxygen is slow and, as a result, the oxygen will deplete very quickly if the systems become contaminated, even if they are aerated before biological treatment. The biological processes would be more efficient if high levels of oxygen were retained in the water for a long time under normal pressure and temperature conditions. Methods are known in which oxygen or air is introduced into water. It has been proposed to introduce air or a mixture of low oxygen content and then introduce concentrated oxygen in water. Thus, the concentration of dissolved oxygen in the water can be increased to 35 mg / l. All processes based on this principle have one common drawback: the low biological activity of the water because of its low content of active oxygen forms since it is saturated with ordinary molecular oxygen.

For example, oxygen-saturated water produced by the above methods quickly loses dissolved oxygen at atmospheric pressure and its level remains within the dynamic equilibrium of the water-luff system, ie, in the range of 6 to 14 mg / 1 at room temperature.

Therefore, methods and apparatus that allow to produce liquids (especially water) having an oxygen content of a magnitude and having a structure in which the biological effectiveness of the water is maintained for a long time are desirable.

The object of the invention is to provide a process for producing oxygen-enriched liquids, in particular water enriched with both active and molecular oxygen (hereinafter referred to as "oxywater"), and also a process for carrying out the process To provide a suitable device, with the stable and highly effective, oxygenated water can be obtained to provide.

This object is achieved in terms of the method, with the features of the main claim of the method and as far as the device is concerned, with the features of the device main claim.

Preferred and advantageous embodiments of the invention are the subject of the dependent claims.

The inventive method for saturating liquids with

Oxygen and its active forms primarily refer to the saturation of drinking water, water for water therapies, use of saturated water in industry and agriculture as well as saturating polluted plant and household water. The saturation of other liquids with oxygen and its active forms to optionally transfer active oxygen to other liquids and gases is also contemplated within the scope of the invention.

The principal difference between the method according to the invention and known methods consists, for example, in the following features:

prior to introduction into the liquid, the pure oxygen is activated, whereby it is converted into various active forms and at the same time moistened, which promotes stabilization of these forms until they enter the liquid;

the activation of oxygen takes place in a device with only low energy consumption;

- The saturation of a liquid, in particular of water, with activated oxygen is carried out in an embodiment according to the invention in a column-type absorber with granulated packing, which increase the surface of the liquid in contact with oxygen;

- The packing are preferably made of silicate material;

- The liquid (water) flows in a column down and active oxygen upwards;

The saturation of a liquid (water) with active oxygen occurs at a temperature of the liquid and the surrounding air in the range of room temperature and an overpressure of about 0.2 - 2 kPa.

Hereinafter, exemplary reaction equations for the activation of oxygen are reproduced as follows in the process according to the invention (the free-radical, active oxygen forms are indicated by bold points symbolizing unpaired electrons): A. - Oxygen Activation Procedure

1. O = O + H * → H-O-O * - superoxide anion hydroperoxide radical

2. O = O + hv * → -OO * - singlet oxygen 3. 3 O ₂ + hv * → 2 O ₃ ozone

B. - Oxidation processes

4. H-O-H + -O-O * - → H-O-O * - + - * O-H

C. - Formation of higher peroxides

5. HOO * - + - * OH → HOOOH (H ₂ O ₃ )

6. HOO * - + - * OOH → HOOOOH (H ₂ O ₄ ) 7. HOOOH + -OO * → HOOOOOH (H ₂ O ₅ ) and their overall formula: - H ₂ O _n where n = 3,4,5, 6,7, ...

In the reaction scheme shown below, the interactions of oxygen and its active forms are shown by way of example:

Investigations of the conditions for the course of these reactions have shown that the water is not only one of the reagents that promote the occurrence of some active oxygen forms (eg reaction 4). Thanks to its structuring, water is the prerequisite for both their occurrence [Chetverikov AG, Blumenfeld LA, Fomin GV: Possible Mechanisms for the Emergence and Elimination of Free Radical Stages in Cells; Biofizika (Moscow) vol. X, pp. 476-486, 1965; Xu X, Muller RP, and Goddard WA: The gas-phase reaction of dioxygen with water singlet: A water-catalyzed mechanism, Proc. Nat. Acad. Be. USA, vol. 99, pp. 3376-3381, 2002], as well as for their further stabilization, since the mentioned active oxygen forms promote the formation of clathrate structures from water molecules around them, which protect them from rapid disintegration or mutual recombination of radicals [Goidberg PJ Chem. Phys. , vol 40, p 427, 1964; Kislovskii LD: A possible molecular mechanism by which solar activity affects biosphere processes. In: Effects of solar activity on the earth's atmosphere and biosphere; Gnevyshev MK and Ol 'AL, eds, "Nauka" Mosskva, 1971]. Clathrates are three-dimensional, closed structures whose scaffolds are made up of water molecules that are bound together by hydrogen bonds, and that have spaces on the inside where space-sized particles of molecular dimensions, especially active oxygen forms, can be accommodated. The activation of the oxygen in the device described below and the incorporation of active oxygen into the water ensure an efficient realization of the physical-chemical processes, in which the activation of the oxygen and the stabilization of the activated oxygen before the time of its dissolution in the water and after its introduction into the water.

Further details and features of the invention will become apparent from the following description of preferred embodiments with reference to the accompanying drawings. 1 shows schematically a system for saturating water with oxygen, FIG. 2 shows a detail of the device from FIG. 1 and FIG. 3 shows a diagram of the dynamics of saturation of water with activated oxygen.

The activation of oxygen takes place in a device according to Fig. 1 and 2 .

Oxygen from bottles 4 (purity: 99.9%) is controlled by a control organ 9, passed through an activator 8 ("plasma memotron" in FIG. 2). From the activator 8, active oxygen enters a separator 2. The activator 8 is supplied with electrical energy from a power supply 5, which can also serve as a control unit.

The operating voltage of the power supply 5 is for example 220 V, that of the activator 8 between 110 and 220 V. The current is set between 2 and 30 amps. The ratio between the amount of electrolytic solution and gaseous oxygen in the activator 8 is 1:10 to 1: 150 liters. The temperature of the mixture of electrolyte solution and oxygen in the activator 8 is at stable operating conditions 30 to 90 ° C.

The process parameters to be observed in the oxygen activation are selected and set taking into account the requirements for the amount and content of oxygen and its active forms in the water.

The nature of the electrolyte solution, its constituents and the concentration of electrolytes in the solution are also chosen taking into account the requirements of the final finished product. For example, in the production of drinking water with an average content of oxygen and its active forms of 25-35 mg / 1, an alkaline electrolyte having a basic substance content of the order of 4% is used. The electrolyte solution is prepared in advance and supplied from a reservoir 2a.

An example of the composition of the usable electrolyte solution according to the invention is the following:

An alkaline electrolyte containing alkaline substance, e.g. Sodium hydroxide (NaOH) of water 4 +/- 1%.

The plant parts contained in the part marked "sector A" in FIG. 1 serve to produce activated oxygen.

Under the conditions described above (load voltage of the actuator) vators, current, bath composition) arises in the course of the work of the activator stable luminescence in the cathode region and it is also a noise generated. These factors, along with the ionization of the electrolyte at current flow, promote the intense activation of molecular oxygen flowing through the activator by production of the atomic (active) oxygen in the cathode region (Krasnovsky AA Jr., Drozdova NN, Ivanov AV, Ambartsumian RV: Activation Biochemistry (Moses) 2003, 68 (9), pp. 963-966; Domrachev GA, Selivanovskii DA, Didenculov IN, Rodigin Yu.L., Stunzhas PA: Temperature dependence of efficiency of sonolysis and intensity of solonuminescence of water, Zhurnal Fizicheskoi Himii., 2001, 75 (2), pp. 363-368).

The parts of the plant contained in the part labeled "sector B" of Fig. 1 serve to saturate a liquid (in the example: water) with oxygen and its active forms.

In this plant part, a countercurrent absorption in a column 1 containing silicate-containing packing Ia at a pressure of 0.2 - 2 kPa and a temperature of at most 25'C listed. This procedure allows the production of the final product (water containing activated oxygen) to be varied, both in terms of capacity, for example from 1.5 t / h to 6 t / h, as well as the oxygen concentration between, for example 15-25 and 60mg oxygen / ml liquid.

The advantage of the method according to the invention over a method in which oxygen is injected into the liquid (water) can be seen from the diagram (FIG. 3) of the results of exemplary embodiments with a capacity of 3 t / h.

In this diagram, "Series 1" corresponds to the course of saturation of water with activated oxygen in the injection process. The dynamics represented by "Series 2" shows the saturation of water with activated oxygen in the inventive countercurrent absorption process in a column with silicate material-containing packing. It has been found that the process according to the invention allows the time for the enrichment of water with activated oxygen to a concentration of 35 mg / 1 to be increased by 60% which makes the plant more efficient and allows it to react flexibly to requirements for the production of water with different degrees of saturation.

For enriching / saturating natural water from a well (well, spring) is used, which corresponds to drinking water standards. The cleaning is carried out in a two-stage filter 6. The purified, clarified and possibly sterilized by UV irradiation 12 water is collected in a container 3 and conveyed from the container 3 with a pump 7 in the upper part of the column 1. Water flows down the column 1 along the silicate filler Ia - activated oxygen flows upwards - and, unless its oxygen content reaches the predetermined value, is returned to the container 3 for a second circulation.

When the oxygen content in the water has reached the desired value, water in a pipeline is brought to the filling and packaging department for final processing. The currents in the lines of the system of FIG. 1 are controlled by shut-off and regulating devices 9, 10.

Known is the mixing method of gas and liquid for achieving a mutual chemical reaction according to JP 58174228, wherein the gas-reacting liquid passes to a reaction the (reaction boxes) filling material which is liquid wettable and gas-permeable, such multiple departments in a are installed horizontally oriented column through which gas is blown laterally under pressure and the liquid is supplied from above into the reaction departments. The disadvantage of this method is that gas must be introduced into the column under pressure so that it penetrates from one section of the column to another. In order to eliminate this disadvantage, according to the invention, the activated oxygen from the separator 2 is fed from below into the packed bed Ia in the column 1 and flows against the water flow from bottom to top.

Activated oxygen passes from the separator 2 from below into the

Füllschichtschicht Ia in the column 1 and flows against the water flow with an overpressure upwards, which only to compensate for the decrease in the oxygen pressure due to its resolution in the water and serves to prevent that due to the decrease in the pressure in the column, external gases are sucked into it. Unabsorbed oxygen and leaves the column via a water seal 11, which serves primarily to isolate the absorption zone in the column 1 from external contamination.

The ratio of the flows of water: oxygen is 80: 1. The absorption temperature is equal to the ambient temperature.

The control and regulation of the functions of the oxygen activation and water saturation sections A and B can be done with a computer controlled system.

Activation of oxygen is accomplished using the equipment portions of the apparatus of sector "A" in FIG. 1, notably the activator 8 shown in greater detail in FIG.

Activator 8 (plasma motorotron) is designed and manufactured according to the planned performance of the plant. A typical plasma chemotron has a hollow plastic housing 11 in the bottom of which a hollow, metallic cathode 13 is mounted. Through the cavity in the cathode 13 electrolyte solution is passed from the separator 2 in the activator 8, whereby the cathode 13 is cooled. The anode 12 is spaced around the cathode 13 and perforated. From an annular manifold 14, the oxygen from the bottles 4 is supplied, escaping oxygen is uniformly distributed from the perforated anode 12 in the reaction zone. The level of electrolyte solution in the housing 11 is controlled by means of overflow 20 via an opening 21 in the housing 11 or via a device. Instead of the overflow, an (arbitrarily designed) other device for regulating the liquid level can also be provided.

The reliability of the activator 8 is ensured by switching off current to the cathode 13 and the anode 12 when in the housing 11 no more electrolyte solution is present.

The operating voltage of the power supply 5 is up to 220 V, that of the

Activator 8 between 110 V and 220 V. The current is set from 2 to 30 amps. The relationship between the flows of Electrolyte solution and the gaseous oxygen is 1:10 to 1: 150 liters.

The temperature of the active mixture (oxygen and electrolyte solution) is 30 to 90 ° C under stable operating conditions.

The process parameters to be observed during oxygen activation are determined by the requirements for the amount and content of oxygen and its active forms in the water.

For example, the following conditions can be met during operation of the activator 8:

1. Operating voltage of the power supply 220 V

2. Operating voltage of the plasma memotron 150V

3. Current 6 amps

4. Relationship between the flows of

Electrolyte solution and gaseous oxygen 1:50 liters

5. Temperature of the active mixture 72 degrees Celsius

6. Electrolyte with basic substance content NaOH

The following describes properties of activated oxygen-enriched water ("oxywater") obtainable according to the present invention.

The main advantages of water obtained according to the invention are that water obtainable according to the invention has special properties, that it exerts an unusual influence on microorganisms which come into contact with it, that it has a favorable effect on physical endurance and that it affects the De - Reduced pressivity of laboratory animals (rats).

A microbiological analysis of water obtainable according to the invention and of water ("oxywater") from a well (source) Water) has shown that in most samples, the content of microorganisms is very low, they also represent all human-harmless, saprophytic forms. It is particularly striking that the microorganisms present in the present invention available water strong are inhibited.

To determine whether microorganisms are present in the water, it is applied to a Petri dish with a standard agar medium and incubated for one day at an optimal temperature for cell proliferation, after which the number of colonies is counted. The microorganisms of artesian water and water obtainable according to the invention have formed colonies only after two to three days, i. much later than microorganisms from ordinary water.

In addition, the microorganisms from water obtainable according to the invention have formed very small colonies whose dimensions are smaller than those of artesian water. This shows a very low reproductive capacity of the microorganisms living in these waters, but especially in the water obtainable according to the invention. Even in water obtainable according to the invention, which was stored in closed bottles for one year and in which the content of microorganisms was markedly higher than in fresh water obtainable in accordance with the invention, the reproductive capacity of the microorganisms remained at a low level.

It should be emphasized that after the bottles were opened with water obtainable according to the invention and the microorganisms contained in the air were accessible to the air, at least within two weeks no increase in the number of microorganisms was observed, ie open water does not become "foul" during this time and remains drinkable from a microbiological point of view. Microbial growth did not begin until the water was exposed to air for three weeks. But even then, microorganisms grew only very slowly.

If the water obtainable according to the invention intentionally added microorganisms in an amount exceeding that which the microorganisms incubate for eight days with air supply could not be ascertained. This effect of the water according to the invention was observed in a whole series of microorganism strains belonging to different microbial species.

In addition, a bactericidal effect was observed for some types of microorganisms - within a few days of incubation, their content in the water obtainable according to the invention dropped to a level permitted by sanitary standards.

At first glance, this effect is not surprising, because microorganisms need nutrients for their growth that are not found in artesian water. It was surprising, however, that the "oxy-water" obtainable according to the invention can modify microorganisms in such a way that their multiplication is inhibited for many generations. For example, cells of the colibacillus (E. coli) which grow out of individual cells on a normal nutrient solution into a colony form much smaller colonies than those which develop from cells after one day of residence in the water obtainable according to the invention. that come from ordinary water.

This change in the properties of the microorganisms took place particularly quickly and efficiently when the oxy-water was stirred.

The small size of the colonies is related to the fact that the number of cells in them is smaller by one to two orders of magnitude, depending on how long the colonies had time to grow than in the cultures of the control cells. In other words, the rate of division of the microorganisms rapidly decreases after contact with water obtainable according to the invention.

When the microorganisms were in water obtainable according to the invention for two days, only small colonies grow in the petri dishes. The cell division is slowed down even after their incubation in the artesian starting water, but the transformation into the slow-growing form is slower than in water obtainable according to the invention. The unusual change in the cells is permanent: if you take a small colony, and the cells forming them in a fresh medium, they grow from them again only small colonies, whereas from cells that belong to large colonies, grow again large colonies. In other words, the change experienced by the cells of the coliform bacteria after their residence in water obtainable according to the invention is permanent.

The modification of the reproductive properties of the cells of the coli bacterium under the action of water obtainable according to the invention can explain the positive effect of a regular consumption of this water on the digestive apparatus. The microorganisms colonizing the gastrointestinal tract of humans and animals play a very important role in normal physiology. They ensure that the digestive processes run efficiently and provide the organism with many biologically active substances (vitamins, regulatory molecules) that the organism itself does not produce or does not produce in sufficient quantities. However, the microorganisms normally living in the intestine only fulfill their functions in the time between cell divisions. Too high a rate of division of the microbial cells in the gastrointestinal tract is usually associated with pathological phenomena and is accompanied by the negative symptoms. The usual method of combating too rapidly dividing cells - antibiotic therapy - is to eliminate not only pathogenic cells but also the normal microflora in the digestive tract. Therefore, antibiotics and other microbicidal agents will disturb the balance that is typical of a normal microflora for a long time, and recovery can take a long time. From this point of view, the "oxy" water obtainable according to the invention is an advantageous agent for the prophylaxis and therapy of gastrointestinal diseases.

It has been found that water obtainable according to the invention normalizes the biological activity of microorganisms without killing them, which has a favorable effect on the digestion and also on other physiological processes in the human organism.

Effects of Water Obtainable According to the Invention on Laboratory Animals:

The immediate effects of water obtainable on the animal organism according to the invention were studied on rats drinking this water, whereas the control group drank ordinary, stale (Moscow) tap water (which also corresponded entirely to hygienic and epidemiological regulations). The results are shown below.

It was found that the rats had increased physical endurance after only three days of consumption of water obtainable according to the invention compared to the control group, and the level of depression was reduced in comparison to the rats which had drunk normal water. These effects occurred, though

Study of young healthy rat males (it can be assumed that the effect of oxy-water on weak and sick animals would have been even greater).

There has also been found a positive effect of enjoying water obtainable on the physical and mental endurance of laboratory animals according to the invention.

Energetic processes in water obtainable according to the invention:

The method and results of investigations of the physical and chemical properties of water obtainable according to the invention in comparison with artesian water are explained below:

The oxygen content in an opened bottle of water obtainable according to the invention is from two to three times the oxygen content in artesian water and other pure water which are in equilibrium with the air. The composition of the salts, the pH and the redox potential of this water make it possible to count it as drinking water of the highest quality. On contact with air, the oxygen content in water obtainable according to the invention decreases and gradually reaches an equilibrium concentration, this process proceeding rapidly when stirring. Consequently, one can explain the above-described biological properties of the water, in particular its influence on the Kolibakterienzellen, especially when stirring the Incubationsproben, not only with an increased oxygen content in the water.

Water obtainable according to the invention, in comparison with conventional drinking water, has a considerably higher energy activity, which is responsible for its particular biological properties.

The water produced by the process according to the invention ("oxy- Water ") may have the following properties, among others.

Water obtainable according to the invention has a bacteriostatic effect on intestinal and other microflora, without having pronounced antibiotic properties.

Water obtainable according to the invention has a favorable effect on the physical and mental endurance of laboratory animals.

The mechanism of biological activity of water obtainable according to the invention is given by its capacity for oxygen activation and autoxidation.

Although active oxygen forms are present in water obtainable according to the invention, it is neither mutagenic nor carcinogenic.

In summary, an embodiment of the invention can be represented as follows:

If pure oxygen is passed through an aqueous alkaline electrolyte in which voltage is applied between the cathode and the annular anode surrounding it, then oxygen is generated by interaction with the active oxygen produced during the electrolysis, by excitation under the action of the various energy sources. gieformen that occur when current is passed through the electrolyzer (in particular sound energy and light energy), activated. The active oxygen is stabilized in the water clathrates and this moist gas mixture is brought into contact in a countercurrent column with the liquid to be oxygenated, wherein the liquid to be enriched, the Gegenstromkolon- ne, which contains a silicate-containing material as filler, from top to bottom and the activated oxygen flows through the countercurrent column from bottom to top. Optionally, the liquid to be enriched is passed through the column several times until the desired degree of oxygen enrichment has been achieved.
