Description

Preparation method of the custom-mineral water and mineral salt from deep ocean water}

The present invention relates to a method for producing mineral water and mineral salts from deep sea water, and more specifically, to a specific mineral such as magnesium, calcium or potassium from deep sea water rich in mineral content and free from contamination by chemicals or bacteria. It relates to a method of producing mineral water and mineral salt that can be selectively separated to control the content of each mineral.

Deep sea water refers to sea water 200 meters or less from the surface of the sea and is called deep sea water separately from surface water. There is no phytoplankton that consumes nutrients in the deep sea where sunlight does not reach, so deep ocean water is rich in nutrients decomposed by bacteria and contains eutrophic (mineral) minerals such as calcium and magnesium. . Less than 200 meters from surface seawater, low concentrations of organic matter, no contamination by Escherichia coli or common bacteria, less likelihood of contamination by chemicals from land or air, less change at low temperatures throughout the year, and formed over thousands of years. Its water is stable. In addition, it is known that the essential trace elements or various mineral components are contained in a balanced manner, and thus have characteristics such as excellent scavenging action against active oxygen due to the action of dissolved metal ions.

Due to the useful effects of deep sea water, various attempts have been made to use salts and beverages having high mineral content from deep sea water. Deep sea water itself has a strong salty taste, so it is difficult to drink as it is, in order to use it, it is necessary to separate the excess salt. However, there is a problem that calcium and magnesium, which are useful hardness and minerals, are also removed in the process of separating salts, and various attempts have been made to compensate for this.

Patents 663084, 688636, 667968, 686979, and the like describe a method for producing mineral salts or mineral water from deep sea water using electrolysis, electrodialysis or reverse osmosis membrane. However, this is simply a method of preparing a beverage or salt from which excess salt (NaCl) has been removed to alleviate the salty taste of deep sea water, or a process of separating monovalent and divalent ions. Therefore, the above technology has a technical limitation in producing a mineral water or mineral salt containing a large amount of the specific mineral by selectively separating specific minerals, that is, magnesium, calcium or potassium, not sodium.

Minerals that are in an ionized state are called active minerals that can be used by the human body, and mineral mineral supplements have recently been reported to have low human utilization because they are not ionized. In addition, the lack of minerals in the body is different depending on the physical characteristics, genetics and lifestyle of the person, so that the minerals can be selectively separated to provide the minerals for each person's characteristics. For example, antagonistic interactions between minerals, for example, sodium and potassium play a major role in maintaining the body's blood pressure and water content while maintaining a balance in the body. Magnesium and calcium also play an important role in maintaining mutual mineral content. If this balance is broken, adult diseases such as diabetes and metabolic syndrome are caused. Therefore, if each mineral component can be selectively separated from the deep sea water containing a variety of active minerals, it will be easy to supply appropriate minerals easily absorbed by each individual.

An object of the present invention is to provide a mineral water selectively containing each mineral by selectively separating specific minerals such as magnesium, calcium or potassium from the deep ocean water by using an evaporator, an electrodialysis device, an electrolysis device and a reverse osmosis membrane device. It is to provide a method for producing mineral salt.

In order to achieve the above object, the present invention, (A) using a secondary evaporator, separating the sodium chloride precipitated by heating and concentrating deep sea water; And (B) selectively separating the minerals using an electrodialysis apparatus combining the monovalent and divalent cation selective exchange membranes and the monovalent and divalent anion selective exchange membranes.

Here, the deep sea water is preferably a brine obtained by separating the brine concentrated ions of the deep sea water and deionized fresh water using a reverse osmosis membrane device before the step (A), the divalent cation selective exchange membrane Silver, calcium ions and magnesium ions can be permeable, it is preferable to be able to separate the calcium ions and magnesium ions using the difference in the transmission rate of the ions, the electrodialysis apparatus, the monovalent cation selective exchange membrane and monovalent anions Primary electrodialysis apparatus combining a selective exchange membrane, secondary electrodialysis apparatus combining a divalent cation selective exchange membrane and monovalent anion selective exchange membrane, and tertiary electrodialysis apparatus combining a monovalent cation selective exchange membrane and a divalent anion selective exchange membrane It is preferable that it consists of. In addition, using a primary evaporator, and before the step (A), may comprise the step of separating the calcium salt precipitated by heating and concentrating the deep sea water, the electrolysis device using a gold, silver or platinum electrode It may include the step of removing the chlorine and sulfate ions using.

In addition, the present invention, (A) using a secondary evaporator, the step of separating the sodium chloride precipitated by heating and concentrating deep sea water; (B) selectively separating the minerals using an electrodialysis apparatus combining a monovalent and divalent cation selective exchange membrane and a monovalent and divalent anion selective exchange membrane; (C) mixing the selectively separated minerals in a mineral water tank such that a weight ratio of potassium ions: magnesium ions: calcium ions is 1-100: 1-100: 1-100; And (D) using a third evaporator, (C) provides a method for producing mineral salt comprising the step of evaporating the water of the mixture.

Here, the deep sea water is preferably a brine obtained in the step of separating the brine concentrated ions of the deep sea water and deionized fresh water using a reverse osmosis membrane device before the step (A), the sodium chloride to all the minerals With respect to 10 to 95% by weight, it is preferred that the mixture of step (C) and / or the moisture after step (D) is mixed with the evaporated mixture. The divalent cation selective exchange membrane may be capable of permeating calcium ions and magnesium ions, and is capable of separating calcium ions and magnesium ions using a difference in permeation rate of ions. Primary electrodialysis apparatus combining a selective exchange membrane and a monovalent anion selective exchange membrane, a secondary electrodialysis apparatus combining a divalent cation selective exchange membrane and a monovalent anion selective exchange membrane, and a combination of a monovalent cation selective exchange membrane and a divalent anion selective exchange membrane It is preferred to consist of one tertiary electrodialysis apparatus. In addition, the calcium ion may include that obtained from the calcium salt precipitated by heating and concentrating the deep sea water using a primary evaporator before the step (A).

Method for producing mineral water and mineral salt from the deep sea water according to the present invention, by using an evaporator, electrodialysis device, electrolysis device, reverse osmosis membrane device can be prepared mineral water and mineral salt selectively containing each mineral. . Particularly, the divalent cation selective exchange membrane used in the electrodialysis apparatus of the present invention can permeate from deep sea water to calcium ions (Ca 2+ ) and magnesium ions (Mg 2+ ), and utilize calcium by using the difference in the rate of permeation. Since ions (Ca 2+ ) and magnesium ions (Mg 2+ ) can be separated, calcium mineral water and magnesium mineral water can be produced more easily.

Hereinafter, the present invention will be described in detail.

The evaporator used in the present invention utilizes the difference in solubility of mineral components, and can be effectively used for separating sodium salts and calcium salts. When the deep sea water is removed through the evaporator to remove moisture, sodium chloride and calcium salts (CaSO 4 and CaCO 3 ) are precipitated according to solubility.

In the present invention, if necessary, a calcium salt precipitated can be separated by heating and concentrating deep sea water using a primary evaporator (primary E / V), and a secondary evaporator (secondary E / V) is used. Thus, the sodium chloride precipitated may be separated by heating and concentrating the filtrate of the deep sea water or the deep sea water from which the calcium salt from the primary evaporator (primary E / V) is removed.

The electrodialysis apparatus used in the present invention is to combine ion selective exchange membranes according to the ions to be separated, for example, when separating monovalent cations and monovalent anions, monovalent cation selective exchange membrane and monovalent anion selection. When a divalent cation and monovalent anion are separated using an exchange membrane, a divalent cation selective exchange membrane and a monovalent anion selective exchange membrane are used. In addition, when the monovalent cation selective exchange membrane and the divalent anion selective exchange membrane are used, the monovalent cation and the divalent anion can be selectively permeated and separated. That is, in the electrodialysis process, the monovalent cation selective exchange membrane selectively permeates monovalent cations first, and the monovalent anion selective exchange membrane selectively permeates monovalent anions first. Therefore, when electrodialysis is performed by a combination of a monovalent cation selective exchange membrane and a monovalent anion selective exchange membrane, monovalent cations such as sodium ions (Na + ), potassium ions (K + ) and chloride ions (Cl − ) and 1 Only anions can be selectively separated and permeated. On the other hand, when the monovalent cation selective exchange membrane and the divalent anion selective exchange membrane are combined, only monovalent cations and divalent anions such as sodium ions (Na + ), potassium ions (K + ) and sulfate ions (SO 4 2- ) are selected. Can be separated and permeated. Divalent cations selected from calcium ion exchange membrane is ocean water (Ca 2+), magnesium ion (Mg 2+) may be transmitted through it, and to separate them, particularly calcium by using a difference in speed is transmitted to the ion (Ca 2+ ) And magnesium ions (Mg 2+ ) can be separated.

For example, the electrodialysis apparatus may first remove potassium chloride, and then combine potassium monovalent cation selective exchange membrane and monovalent anion selective exchange membrane to selectively transmit potassium ions, thereby preparing potassium mineral water, Calcium mineral water by selectively permeating calcium ions and magnesium ions by combining the dialysis or monovalent ion selective exchange membrane of the dialysis apparatus, and separating calcium ions and magnesium ions using the permeation rate difference in the divalent cation selective exchange membrane. And magnesium mineral water. Preferably, the calcium mineral water and the magnesium mineral water may be prepared by combining a divalent cation selective exchange membrane and a monovalent anion selective exchange membrane.

In the present invention, the electrodialysis apparatus, for example, by combining a monovalent cation selective exchange membrane and a monovalent anion selective exchange membrane, selectively permeate potassium ions to produce potassium mineral water, primary electrodialysis apparatus, 2 Combining a valent cation selective exchange membrane and a monovalent anion selective exchange membrane to selectively permeate calcium ions and magnesium ions and separate calcium ions and magnesium ions using a difference in permeation rate, thereby producing calcium mineral water and magnesium mineral water, By combining a secondary electrodialysis apparatus, a monovalent cation selective exchange membrane and a divalent anion selective exchange membrane, a third electrodialysis apparatus may be further separated from the calcium mineral water and magnesium mineral water to further separate monovalent cations and divalent anions. have.

The reverse osmosis membrane device (primary R / O) used in the present invention applies a pressure of 50 to 70 kg / cm higher than that of the deep ocean water to the deep ocean water, so that only the pure solvent (fresh water) escapes from the deep ocean water through the reverse osmosis membrane (semi-permeable membrane). To get out. Using the reverse osmosis membrane device (primary R / O)), it is possible to obtain brine in which ions (mineral components) are concentrated and fresh water from which ions are removed from deep ocean water. As said semipermeable membrane, a cellulose or a polyamide membrane can be used. The fresh water is preferably obtained by permeating the reverse osmosis membrane apparatus at least once. For example, the filtered water that has permeated through the reverse osmosis membrane apparatus (primary R / O) is once through the secondary reverse osmosis membrane apparatus (secondary R / O). It is preferable to obtain further permeation.

The electrolysis device (E / L) used in the present invention is for the removal of chlorine ions (Cl − ) and sulfate ions (SO 4 2- ) using an electrode, which is removed in the form of chlorine gas at the electrode. It can be removed by forming a precipitate, in the case of sulfate ion, by using an electrical force to move the sulfate ion toward the + pole, the mineral water without sulfate ion in the-pole can be obtained. The electrode of the electrolysis device is preferably electrolyzed using gold, silver or platinum electrode. As can be seen in Example 2 below, removal of chloride ions (Cl − ) and sulfate ions (SO 4 2− ) by the carbon electrode is not efficient, and alkali mineral water cannot be obtained. However, gold, silver, or the case of using a platinum electrode on yeomhwayi (Cl -) can be removed and the sulfate ion (SO 4 2-), and the pH can be produced a high number of mineral alkali, using a platinum electrode which It is the most efficient and can additionally remove sodium ions (Na + ). The following is a reaction formula for removing chlorine from the platinum electrode and the gold electrode.

Pt + 2NaCl + 2Cl 2 → (Na) 2 PtCl 6 (precipitation)

2Au + 4NaCl + 1 / 2O 2 + H 2 O → 2NaAuCl 2 (precipitation) + 2NaOH

1 is a general process showing the manufacturing process of mineral water and mineral salt according to the present invention by selectively applying the necessary processes of this process chart can be prepared high mineral water and mineral salt of each mineral content.

The abbreviation used in FIG. 1 is as follows. R / O: reverse osmosis device, ED: electrodialysis device, E / V: evaporator, E / L: electrolysis device, M / T: mixing tank, C / F: centrifuge, M / W: Mineral water tank.

According to the present invention, in order to prepare mineral water from the deep sea water, first, by using a secondary evaporator (secondary E / V), performing the step of separating the sodium chloride precipitated by heating and concentrated deep sea water.

The deep sea water may be used after undergoing a filtration process to remove suspended substances, etc., the filtration process may be carried out by a conventional micro-filter or ultra-filter (Ultra-filter). In addition, by using a reverse osmosis membrane device (primary R / O), by performing a step of obtaining the brine and the fresh water from which the ion of the deep sea water concentrated, the mineral water can be produced more efficiently from the brine.

In addition, calcium salts precipitated by heating and concentrating the brine obtained from the deep sea water and / or reverse osmosis membrane apparatus (primary R / O) using a primary evaporator (primary E / V), if necessary (CaSO 4 and CaCO 3 ) can be separated and dissolved in fresh water obtained from the reverse osmosis membrane apparatus (primary R / O and secondary R / O) to prepare calcium mineral water.

Next, a step of selectively separating minerals is performed using an electrodialysis apparatus combining a monovalent and divalent cation selective exchange membrane and a monovalent and divalent anion selective exchange membrane.

First, sodium chloride and calcium salts having passed through the secondary evaporator (secondary E / V), the filtrate from which sodium chloride has been removed, or through the first evaporator (first E / V) and the second evaporator (secondary E / V). The removed filtrate was put into a primary electrodialysis apparatus (1st ED) which combined a monovalent cation selective exchange membrane and a monovalent anion selective exchange membrane, and separated potassium ions, thereby separating the monovalent cation selective exchange membrane and monovalent anion selective exchange. The potassium mineral water that has permeated the membrane and the remaining filtrate of the remaining ions that do not permeate are separated.

Next, the filtrate of the primary electrodialysis apparatus (primary ED) is introduced into a secondary electrodialysis apparatus (secondary ED) in which a divalent cation selective exchange membrane and a monovalent anion selective exchange membrane are combined to select the divalent cation. Calcium mineral water and magnesium mineral water are obtained by separating calcium ions and magnesium ions using the difference in the permeation rate of ions by the exchange membrane. However, in the case of the filtrate passing through the primary evaporator (primary E / V), since calcium ions were separated in the form of calcium salts, only magnesium ions were separated from the secondary electrodialysis apparatus (secondary ED) to obtain only magnesium mineral water. Can be. In addition, if necessary, the calcium mineral water and magnesium mineral water are added to a tertiary electrodialysis apparatus (tertiary ED) combining a monovalent cation selective exchange membrane and a divalent anion selective exchange membrane, thereby providing the calcium mineral water and magnesium mineral water. It is possible to further separate monovalent cations and divalent anions from water.

By mixing or mixing the calcium mineral water, magnesium mineral water and potassium mineral water produced by the above process, and mixed with fresh water from the reverse osmosis membrane device, it is possible to produce a mineral water with a controlled mineral content, the mineral water Electrolysis using an electrolysis device using gold, silver or platinum electrodes may remove chloride ions (Cl − ) and sulfate ions (SO 4 2- ) from mineral water. In addition, the pH of the mineral water can be adjusted to alkaline to produce an alkaline mineral water. In addition, carbon dioxide gas may be injected into the mineral water to produce carbonated mineral water for a refreshing feeling.

According to the present invention, in order to prepare the mineral salt from the deep sea water, first, by using a secondary evaporator (secondary E / V), the step of separating the sodium chloride precipitated by heating and concentrated deep sea water.

The deep sea water may be used after undergoing a filtration process to remove suspended solids, etc., the filtration process may be performed by a conventional micro-filter or ultra-filter (Ultra-filter). In addition, by using a reverse osmosis membrane device (primary R / O), by performing the step of obtaining the brine and the fresh water from which the ion of the deep sea water concentrated, the mineral salt can be produced more efficiently from the brine.

If necessary, calcium salts (CaSO 4 and CaCO 3) precipitated by heating and concentrating the brine obtained from the deep sea water and / or reverse osmosis membrane apparatus (primary R / O) using a primary evaporator (primary E / V). ) Can be separated and dissolved in fresh water obtained from the reverse osmosis membrane devices (primary R / O and secondary R / O) to form calcium mineral water and mixed with other minerals in the mineral water tank (M / W). have.

Next, a step of selectively separating minerals is performed using an electrodialysis apparatus combining a monovalent and divalent cation selective exchange membrane and a monovalent and divalent anion selective exchange membrane.

First, sodium chloride and calcium salts having passed through the secondary evaporator (secondary E / V), the filtrate from which sodium chloride has been removed, or through the first evaporator (first E / V) and the second evaporator (secondary E / V). The removed filtrate was put into a primary electrodialysis apparatus (1st ED) which combined a monovalent cation selective exchange membrane and a monovalent anion selective exchange membrane, and separated potassium ions, thereby separating the monovalent cation selective exchange membrane and monovalent anion selective exchange. The potassium mineral water that has permeated the membrane and the remaining filtrate of the remaining ions that do not permeate are separated.

Next, the filtrate of the primary electrodialysis apparatus (primary ED) is introduced into a secondary electrodialysis apparatus (secondary ED) combining a divalent cation selective exchange membrane and a monovalent anion selective exchange membrane to select the divalent cation. Calcium mineral water and magnesium mineral water are obtained by separating calcium ions and magnesium ions using the difference in the permeation rate of ions by the exchange membrane. However, in the case of the filtrate passing through the primary evaporator (primary E / V), since calcium ions were separated in the form of calcium salts, only magnesium ions were separated from the secondary electrodialysis apparatus (secondary ED) to obtain only magnesium mineral water. Can be. In addition, if necessary, the calcium mineral water and magnesium mineral water are added to a tertiary electrodialysis apparatus (tertiary ED) combining a monovalent cation selective exchange membrane and a divalent anion selective exchange membrane, thereby providing the calcium mineral water and magnesium mineral water. It is possible to further separate monovalent cations and divalent anions from water.

Next, in the mineral water tank (M / W), the selectively separated minerals (potassium mineral water, magnesium mineral water, calcium mineral water) are added in a weight ratio of potassium ions: magnesium ions: calcium ions from 1 to 100: 1. The mixture is obtained by mixing 100: 1-100, preferably 1-50: 1-50: 1-50. The weight ratio of the potassium ion: magnesium ion: calcium ion can be freely adjusted according to the desired purpose and use.

Here, the calcium ion is, before the secondary evaporator (secondary E / V), by using the primary evaporator (primary E / V) by heating and concentrating the deep sea water of the calcium salt precipitated by the reverse osmosis membrane device ( It can be obtained from calcium mineral water made by dissolving in fresh water obtained from primary R / O and secondary R / O, and can be mixed with other minerals in mineral water tank (M / W).

Next, the water of the mixture is evaporated using a tertiary evaporator (tertiary E / V). Here, the sodium chloride separated by the secondary evaporator (secondary E / V) is 10 to 95% by weight, preferably 20 to 80% by weight relative to the total mineral, the mineral water tank (M / W) In the melt dissolved in the mixture or mixed with the mixture of the water evaporated in the tertiary evaporator (tertiary E / V) in a solid state can be prepared mineral salts. When the content of sodium chloride is less than 10% by weight relative to the total minerals, the salt (NaCl) content is too small to be called salt, and when it exceeds 95% by weight, the mineral content of the mineral salt is too small to mean as mineral salt There is no. However, even when sodium chloride is less than 10%, it can be used for seasoning and the like.

Hereinafter, preferred examples for aiding in understanding the present invention are presented. The following examples are intended to illustrate the invention and are not intended to limit the invention.

In the following examples, cations were analyzed using ICP (inductively coupled plasma) and ppb units were used for ICP-MS. In the case of anions, they were quantified using IC (ion chromatography).
