The present invention relates to chemical technology and engineering water treatment and packaging for storage, filling and corking quality of water in airtight containers, prepared for long-term storage.

The invention can be used in industrial production of high-quality water. The specific implementation of the invention it is planned in the industrial production of bottled kislorodozawisimae drinking water and drinks with trademarks “SUPERMODE”, “HYDROXY”, “LIGHT WATER”, “JUICE of LIFE” and others.

Analysis of scientific-technical and patent information [1, 2] shows that in the known technical solutions, the oxygen saturation can be accomplished by mixing the oxygen-containing gas with water and less effectively by spraying (spray) water in the oxygen-containing gas with subsequent coalescence (sticking together) of droplets of water and diversion of the gas mixture.

In the first case, the oxygen is in the water in the form of tiny bubbles of oxygen-containing gas, of which molecular oxygen adsorbed water interphase gas - liquid and saturates the water.

In the second case, the oxygen is oxygen-containing gas, in which a spray of tiny droplets of water. Molecular oxygen adsorbed water interphase liquid - gas.

The interfacial boundary of the bubble oxygen-containing gas in the water and water droplets in the oxygen-containing gas may be charged by the electric field, the photons of high energies, surface-active agent and other physico-chemical conditions that affect the depth of saturation of water with oxygen and the rate of transition of molecular oxygen through the interfacial boundary.

Known method of preparing bottled kislorodozawisimae drinking water and equipment for its implementation [3].

In this way, as well as in pressure flotation [2, s], the water is injected under pressure (6 MPa) and low temperature (not more than 10° (C) oxygen. Then supersaturated with oxygen water spray into the air stream under reduced pressure (3 MPa) and low temperature. Enriched oxygen from droplets of supersaturated oxygen water air is mixed under pressure with air-conditioned drinking water in a separate pressure accumulation tank, from which it is sent for bottling.

The method also provides for the mixing of two gases (O₂and CO₂)used to improve the taste of drinking kislorodozawisimae water.

Supersaturated oxygen in an environmentally friendly way [3] with the oxygen concentration of 10 to 40 mg O₂l H ₂O drinking water is directed under pressure to the bottling. After the operation of filling the bottle with kislorodozawisimae water clog. Airtight containers (bottles and caps) pre-sterilized known methods [1].

The complex of equipment for implementing the method [3] includes installation of saturation of water with oxygen, consisting of series-connected cumulative pressure vessels (columns) for collecting and processing water oxygen-containing gas under pressure, an auxiliary equipment to support the installation of saturation of water with oxygen excess pressure and low temperature, installation of bottling and corking kislorodozawisimae water in bottles, connected by pipeline to the installation of saturation of water with oxygen.

Building complex patent [3] is the most similar (according to the set of equipment required for the production of bottled kislorodozawisimae drinking water) in the claimed technical solution.

Disadvantages of the method of preparation of bottled kislorodozawisimae water [3]:

- unstable supersaturated oxygen status of drinking water, poured into bottles under pressure during storage and when opening a sealed bottle);

- high energy consumption for the process of saturation of water with oxygen, related the data with maintenance of overpressure in the columns, low water temperature and flow rate of oxygen-containing gas.

The disadvantages of complex equipment for implementing the method [3]:

- high energy and material intensity of the equipment saturation of water with oxygen;

- the penetration of microorganisms during filling kislorodozawisimae water in bottles and sealing plugs (disinfected bottles from microorganisms to the operation of bottling);

- the possibility of ignition in oxygen at a pressure of engine oil, a couple of which can be accessed from the auxiliary equipment in the installation of saturation of water with oxygen.

There is a method of cooking kislorodozawisimae drinking water and installation for its implementation in the industrial production of bottled water [4].

This method consists of mixing oxygen-containing gas processed chilled water under pressure (as in pressure flotation [2, s]) to obtain supersaturated oxygen status of the treated water.

Unlike technical solutions [3] drinking water pre-treatment reverse osmosis and electrolysis method.

Energy-intensive physical and chemical processes used in the installation of saturation of water with oxygen [4] to improve the stability of supersaturated oxygen state is of water by reducing the concentration of salts in the water and enter into the water charged bubbles N ₂+O₂electrolysis gas.

Known physico-chemical methods of pre-treatment of drinking water have a number of disadvantages:

the electrolysis of water causes pollution of drinking water by the products of electrolysis (active chlorine, heavy metal ions);

- desalination by reverse osmosis to the level of distillate negative effect on the cells of the esophagus (causing them osmotic shock).

For clean oxygenated drinking water of the above methods pre-treatment can be used only modified electrolysis to generate oxygen-containing gas mixture H₂+O₂[5].

Products pollution oxygen-containing gas mixture H₂+O₂this technical solution is only water vapor and vapors of alkali.

In the claimed complex construction of electrochemical systems [5] was used in the construction of plasmamembrane system synthesis gas mixture of H₂About₂+O₂based on a patent [6].

The method of saturation of water with oxygen and installation for its implementation [4] inherent disadvantages described in the known technical solution [3].

Taking into account the conducted analysis of scientific-technical and patent. information technical solution to the problem is the item is improving the efficiency of water treatment oxygen-containing gas through achievement of deep oxygen saturation of water (30 to 40 mg O ₂/l H₂A) stable in time supersaturated oxygen status of the water under normal conditions, reducing energy consumption for the process of saturation of water with oxygen and energy complex for implementing the method.

The solution is achieved:

1. A sequential ejection pressure flotation mixing obtained plasmamembrane. by way of oxygen-containing gas mixture H₂About₂+O₂patent [6] with treated water, allowing to increase the efficiency of water treatment oxygen-containing gas, to apply a streamlined, low system pressure flotation in the production of bottled oxygenated water, to reduce the energy consumption for water treatment.

2. The use of anomalous physical-chemical properties of oxygenated steam-N₂About₂+O₂mixtures for deep saturation of the treated water oxygen and sustainable in time supersaturated oxygen status of the treated water under normal conditions.

3. The use of anomalous physical-chemical properties of oxygenated steam-N₂About₂+O₂mixes instantly (within seconds) to dissolve when mixed with the treated water for its ejection input to the pressure of the flotation system is between the pump and the column (capacity).

4. The use of anomalous physical-chemical properties of oxygenated steam-N₂About₂+O₂the mixture interact with remasterise materials and hydrocarbon polymers used in the water treatment system of oxygen-containing gas mixture.

The above analysis of the prior art has allowed to establish that the analogs are characterized by the sets of characteristics is identical for all features of the claimed method and system for its implementation, no. Therefore, each of the claimed invention meets the condition of patentability “novelty”.

From a certain higher level of technology not identified popularity of influence provided the essential features of each of the claimed inventions transformations to achieve a technical result. Therefore, each of the claimed inventions corresponds to the level of patentability “inventive step”.
