The present invention is expected to be widely used as the water in liquor production because it is hygienically safe when the demineralized water of the deep sea water is used as the liquor manufacturing water (fermented water) in Cheongju manufacturing.

First, when examining the characteristics of deep sea water, deep sea water is usually called deep sea water deeper than 200m from the sea surface. Due to the high concentration of nutrients and the density difference according to the water temperature due to the inability to proliferate and living organisms, there is no contaminant present in the surface seawater because it is not mixed with the surface seawater. Mineral balance with abundant minerals, pollutants, very low levels of harmful bacteria and organic matter, rich in nutrients and inorganic minerals, which are very important for plant growth. Mineral balance characteristics and clusters of water molecules are small grouped for a long time under high pressure and low temperature, so the surface tension is small and permeability is low. It has characteristics such as ripening matured with good water.

Deep sea water is a deep seawater that is not exposed to sunlight and does not mix with the surface sea water. Sea deep sea water, which is deeper than 200 m from the sea surface, is called deep sea water. Calcium (Ca), magnesium (Mg), iron (Fe), and zinc (Zn) required for the growth of fermented microorganisms as shown in Table 2 "Analysis Value of Deep Seawater and Superficial Seawater" without containing any harmful bacteria. ) There are more than 70 kinds of mineral components such as sodium and sodium, and nutrients, viable bacteria, and water temperature have significant differences.

The history of deep sea water use is short, and various researches have been conducted in the non-fish fields such as food, medicine, health industry, beverages, and cosmetics, starting with the fishery field, and deep sea water has the following characteristics.

1. Low temperature safety

While the surface temperature of surface seawater fluctuates greatly with the seasons, deep ocean waters are stable at low temperatures without changing the water temperature with seasons.

In particular, deep sea waters in the East Sea of Korea settled by dense differences in cold seawater that melted drift ice in the Sea of Okhotsk, off the coast of Vladivostok between Ostrov Sakhalin and Hokkaido. As the deep water flows in and blocks the Japanese archipelago, it slows down the water, and the water depth is deeper than 300m from the sea level. The water temperature is 1 ~ 2 ℃ throughout the year, off the coast of Muroto in Kouchi Prefecture, Hawaii or Japan. Is about 8 to 11 ° C lower than deep ocean water.

2. Cleanliness

Because it is deep, it is difficult to receive pollution from river water and air on land, and there are few chemicals, pollutants and bacteria.

① physical cleanliness

Physical cleanliness is said to include less suspended matter and suspended matter. Deep sea water has less suspended solids than surface seawater.

② biological cleanliness

The biggest problem in the intake of seawater is the propagation of adherent organisms. In general, in the surface seawater intake system, the adherent organisms propagate in the intake pipe, and the resistance of the pipe increases, making it impossible to take in water. The total viable counts of microorganisms, (pathogenic) microorganisms, and chlorella are small, ranging from one tenth to one hundredth of surface waters.

③ chemical cleanliness

Since deep seawater does not mix with contaminated surface waters, it is not contaminated with so-called environmental pollutants such as dioxins, PCBs, organic chlorine compounds, and organic tin.

3. eutrophicity

The deep ocean water contains about 5 to 10 times more inorganic nutrients than nitrogen, phosphorus, and silicic acid, which are the nutrient sources of phytoplankton (mainly diatoms, microscopic single-celled plants with chlorophyll), which are the source of sea life compared to surface seawater. There is a characteristic that abundant salt is contained.

At sea levels deeper than 150 m above sea level, the amount of light is less than 1%, and at further depths, phytoplankton are unable to photosynthesize, so nutrients are not consumed by phytoplankton, but sink and accumulate in the deeper layers below, resulting in inorganic nutrients. The concentration of is high.

4. Characteristics of minerals

Sea water contains more than 70 kinds of elements, and deep sea water has such characteristics.

Although there are many important elements necessary for the growth of animals and plants, they are necessary, but very small amounts of deeply related to human health, such as copper and zinc, essential trace elements that are harmful to intake in large quantities, are contained. .

5. Aging

Deep seawater has a lower pH than surface seawater (around pH 7.8), and has a low organic content, while deep seawater separates from surface seawater and has a small cluster of water molecules for many years under low pressure and high pressure. The water quality is stable with micro-clustered water.

Water molecules form clusters by hydrogen bonding, and the method of measuring the number of such water molecule populations is currently known as Nuclear magnetic resonance (NMR). ¹⁷ O-NMR Spectrum half-width of () is estimated indirectly, and approximately 1/10 of the nuclear magnetic resonance ¹⁷ O-NMR Half-width (폭) of the water molecules It is known as the number of groups.

It has been found that when the hydrogen bonds of water molecules are partially broken down and small grouped, the surface tension decreases, the permeability is improved, and the cooling feeling is excellent. .

In general, the value of nuclear magnetic resonance ¹⁷ O-NMR half-width is from 130 to 150 로부터 when produced from river water, and the depth of ocean deep water varies considerably depending on the place.Urasoe, Okinawa Prefecture, Japan The depth of nuclear magnetic resonance ¹⁷ O-NMR was 78 경우 for the deep sea water taken at 1,400 meters offshore, and 65.5 해양 for the deep water taken at 650 m off the Ulleungdo Honpo. As such, water having a small value of the nuclear magnetic resonance ¹⁷ O-NMR half width is referred to as microclustered water.

Deep sea water has the same characteristics as above, but in order to use it as fermentation water in Cheongju manufacturing, remove excess salt and adjust hardness with mineral adjuster, and also nuclear magnetic Nuclear magnetic resonance ^{17 When} the value of the O-NMR half-width is 70 Hz or more, it is necessary to modify the water because the cooling feeling is inferior.

In addition, the deep sea water contains boron compounds in the range of 4-5 mg / l, but it is difficult to treat the drinking water below 0.3 mg / l by the simple nanofiltration and reverse osmosis filtration or electrodialysis treatment.

Boron compounds contained in deep sea water exist in the form of boric acid (H ₃ BO ₃ ), and since the particle size is small as the ion radius is 0.23Å, the drinking water standard is less than 0.3mg / ℓ by simple nanofiltration and reverse osmosis filtration. It is difficult to treat, and also has a dissociation constant pKa value of about 9, which is almost undissolved in the deep ocean water, and hardly exists in the ionic state. Since the treatment is difficult to be treated with the treatment standard value of 0.3 mg / l or less, the boric acid should be converted to poly boric acid in the gel state by treating the pH with an alkali of 9 to 11, followed by reverse osmosis filtration. Boron compound can be removed.

In the hardness adjustment process, the mineral modifier can selectively remove monovalent salts such as NaCl and KCl from the electrodialysis or electroextraction apparatus using the monovalent cation selective exchange membrane and monovalent anion selective exchange membrane in the deep sea water, and then remove Ca / Mg. The commercially available product which adjusted mineral balance to the weight ratio of 2-6 is used.

And a reforming process is performed by the water reforming process.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

I. Pretreatment of deep ocean water

1. Intake and heating treatment process

The deep sea water is taken from the deep seabed deeper than 200m from the sea surface and warmed to 20 ~ 30 ℃ so that the subsequent treatment can be smoothly processed.

The deep sea water intake method is to take down the pipe from the ship to deeper than 200m below sea level, install the pipe to the deep seabed deeper than 200m from the sea level, or take it with a pump, or deeper than 200m from the sea level. Piping is installed to the bottom of the sea floor, and the intake well is installed below the sea level, and the water is collected according to the siphon principle.

The deep sea water collected in the sump is low in temperature and high in viscosity, resulting in low treatment efficiency, so it is supplied with heat from a boiler (in summer, the surface water temperature may be used), and then warmed to 20 to 30 ° C. Send to fair

2. Pretreatment Filtration Process

Pre-filtration filtration process removes suspended solids (SS) from filtration by combining one or more processes among sand filtration, microfiltration, ultrafiltration, or nanofiltration. Deep water is sent to the first desalting stage.

At this time, the filtration pressure is determined in consideration of the pressure loss of the filter and the pressure loss of the pipe according to the operating conditions.In the case of sand filtration, the filtration speed is 6-10 m / hour, and the effective diameter of the filter sand Is 0.3 to 0.45 mm, the uniformity factor is 2.0 or less, and the thickness of a fibrous layer is 0.5 to 1.0 m.

At this time, when the turbidity of the deep ocean water withdrawn is 2 mg / l or less, it is not necessary to carry out sand filtration.

Precision filtration and ultrafiltration are not dependent on the type of filtration membrane, and the supply pressure of the pump is determined in consideration of the filtration rate and the pressure loss according to the specification of the vendor.

In microfiltration or ultrafiltration, filtration treats the water's fouling index (FI) in the range of 2-4.

The FI value is a numerical value representing the fine turbidity concentration in the target water and is expressed by the following equation.

FI = (1-T ₀ / T ₁₅ ) x 100/15... … … … … … … … … … … … … … … … … … … … ①

Where T ₀ is the time required for filtration of the first 500 ml of sample water when the sample water was filtered under pressure of 0.2 MPa using a 0.45 μm microfiltration membrane, and T ₁₅ was filtered for 15 minutes in the same state as T _0. It is time required for filtration of 500 ml of sample water after that.

In nanofiltration, when the subsequent desalting treatment is performed by reverse osmosis filtration, electrodialysis or electroextraction, the deep ocean water from which sulfate ions (SO ₄ ^{2 −} ) are removed is removed to boron.

The nanofiltration membrane module can be in any form, such as tubular, hollow fiber, spiral wound, or plate and frame. May be used, and the material of the film is not particularly limited.

As the material of the nanofiltration membrane, polyamide-based, polypiperazineamide-based, polyesteramide-based or water-soluble vinyl polymer may be used. The structure has a dense layer on one side of the membrane, and is an asymmetric membrane composed of micropores gradually from a large pore toward the inside of the membrane or toward the membrane on one side, or a dense layer of such an asymmetric membrane. A composite membrane having a very thin separation functional layer formed of another material on the layer can be used, and a piperazine polyamide-based composite membrane is preferable, but the material and structure of the membrane are not particularly limited in the present invention. Do not.

Nanofiltration The scale (Scale) sulfate ions that cause generation in the first desalting step of the post-treatment (SO ₄ ^{2 -)} as is the main purpose to remove, deep ocean water, removing the suspended solids in the water in the pre-treatment filtration nano The sulphate-containing water which is not sent to the filtration apparatus is discharged, and the filtered water is sent to the first desalination process.

Transmission sequence of the ion in the nanofiltration membrane, if the cation is ^{Ca 2 +> Mg 2 +>} Li +> Na +> K +> NH 4 + and, in the case of the anion is _{^{SO 4 2 - »HCO 3 ->}} F ^{-> Cl -> Br ->} NO 3 -> ₂ a SiO, sulfuric acid ions (SO ₄ ^{2 -)} for it is difficult to permeate than Mg ^{+ 2} and Ca ^{+ 2.}

In the nanofiltration system, the supply pressure is 15 to 20 kg / cm 2, which is lower than the osmotic pressure of 25 kg / cm 2 of the deep seawater with a salt concentration of 3.5 wt%, and the membrane permeability is 0.7 to 1.4 m 3 / in the spiral type. If m 2 · day, the membrane permeate amount is 70 to 80% of the inflow rate.

II. Desalination Stage

The deep seawater treated in the pretreatment filtration process is desalted by a desalination process combining at least one of reverse osmosis filtration, electrodialysis, electroextraction, freezing, evaporation and condensation, or ion exchange. Send to pH adjustment process of removal step.

When desalination is carried out by evaporation or condensation, or after desalination by reverse osmosis filtration, electrodialysis, electroextraction or freezing, and then desalination is performed by ion exchange. When the concentration of boron in the demineralized water is treated within 0.3 mg / l, it may be sent to a hardness adjustment step or a water reforming step, or the hardness may not be appropriate, but may be used as manufacturing water in the sake production process for cost reduction.

The reverse osmosis filtration process, electrodialysis process, electroextraction process, freezing process, the desalination treatment process by the evaporation and condensation process and the ion exchange process will be described in detail as follows.

1. Reverse osmosis filtration process

When the deep seawater filtered in the pretreatment filtration process is supplied to the reverse osmosis filtration process, the operating pressure is supplied to the reverse osmosis membrane at 50 to 70 kg / cm 2, and the concentrated brine is not sent to the salt manufacturing process, and the filtered demineralized water is It is sent to pH adjustment process of boron removal step.

When the filtration membrane of the reverse osmosis filtration process is a spiral filtration membrane, when the operating pressure is 55 to 56 ㎏ / ㎠ and the membrane permeate water is operated at 0.5 to 0.8 ㎥ / ㎡ · day, the salinity of the filtered water is removed in the range of 99.0 to 99.85 wt%. 40 to 60% of the influent is filtered.

The shape of the membrane module of the reverse osmosis (tubule), tubular (hollow fiber: hollow fiber), spiral (spiral wound), flat plate (flat plate: frame and etc.) Any form may be used, and the material of the film is not particularly limited.

2. Electrodialysis Process

The deep sea water filtered in the pretreatment filtration process is alternately installed between the positive electrode and the negative electrode of the cation exchange membrane and the anion exchange membrane to supply to the desalination chamber of the electrodialysis apparatus composed of a desalination chamber and a salt concentration chamber, and salt Applying direct current electricity from the rectifier to the anode and cathode while supplying the brine to the concentration chamber, the salt contained in the deep seawater supplied to the desalination chamber is moved to the salt concentration chamber by electrical attraction, and the concentrated brine is made into salt. The desalted water, which is desalted in the desalination chamber, is sent to the pH adjustment step of boron removal.

3. Electric extraction process

The deep sea water filtered in the pretreatment filtration process is supplied from the rectifier while supplying the desalting chamber and the salt extraction chamber of the electroextraction apparatus in which the desalting chamber separated by the cation exchange diaphragm and the anion exchange diaphragm between the anode and the cathode is installed in the salt extraction chamber in multiple stages. When the direct current is applied, the salt contained in the deep seawater in the desalting chamber is transferred to the salt extraction chamber, and the concentrated brine is sent to the salt manufacturing process, and the demineralized water desalted in the desalting chamber is sent to the pH adjustment process of the boron removal step.

4. Refrigeration process

When the deep seawater filtered in the pre-treatment filtration process is supplied to a cooling device with a built-in cooling coil, and the refrigerant is circulated through the cooling coil from the freezer to cool the temperature of the deep sea water in the cooling device to -2 ° C or less. Sherbet ice begins to produce, and salts until the temperature reaches -22.40 ° C and the water concentration reaches 26.285 wt% of the process point (also called Cryohydric point). Low content of sherbet ice is produced. Continued cooling below the process point yields salt-containing ice while producing ice in the form of monoclinic dihydrate, NaCl ₂ H ₂ O.

Therefore, in the present invention, the deep sea water filtered in the pretreatment filtration process produces a sherbet (Sherbet) ice produced while cooling to -22.40 ° C, and then dissolved and desalted water is sent to the pH adjustment process of boron removal step.

5. Evaporation and Condensation Process

The deep seawater filtered in the pretreatment filtration process is supplied to the evaporator, and condensed condensed water is used as the preparation water of the Cheongju manufacturing process by condensing steam evaporated by heating, or sent to the hardness adjustment process or the water reforming process.

If the concentration of boron in the condensate condensed in the evaporation and condensation process is within 0.3mg / l, the drinking water standard, the boron removal step is not necessary. .

6. Ion Exchange Process

When the deep seawater filtered in the pretreatment filtration process is directly treated by an ion exchange process, since the concentration of salt is too high and there is no economic feasibility, in the reverse osmosis filtration process, electrodialysis process, electroextraction process or freezing process, The demineralized water after removing the salt by sequentially passing the first desalted water through the cation exchange resin tower, the anion exchange resin tower, and the positive / anionic amphoteric resin tower is used as the manufacturing water of the Cheongju manufacturing process, or the hardness adjustment process or water Send to reforming process.

If the concentration of boron in the demineralized water deionized in the ion exchange process is within 0.3mg / l of the drinking water standard value, the boron removal step is not necessary, which is not suitable for the sake of cost reduction but can be used as manufacturing water for the sake production process. have.

III. Boron Removal Step

1. pH adjustment process

Boron is contained in the deep sea water in the form of boric acid (H ₃ BO ₃ ) while it is contained in the range of 4-5 mg / l, and the particle size is small as the ion radius is 0.23Å. Drinking water is less than 0.3mg / ℓ, treatment is difficult, the dissociation constant pKa value is about 9, it is almost undissolved in the seawater, and rarely in the ionic state Since the treatment is difficult to treat the drinking water below 0.3mg / l even by electrodialysis and electroextraction, boric acid can be treated with alkali (Alkali) of pH 9-11. And then sent to reverse osmosis to remove the boron compound.

When boric acid in water is subjected to alkali treatment, it is converted into polyboric acid in gel state by the following reaction of ②.

B (OH) ₃ + OH ^_ → [B (OH) ₄ ] ^- → [B ₃ O ₃ (OH) ₄ ] ^- → [B ₄ O ₅ (OH) ₄ ] ^2- → [B ₅ O ₆ (OH ) ₄ ] ^- … ②

2. Reverse osmosis filtration process

In the pH adjustment step, the pH was adjusted to be in the range of 9 to 11, and the boron compound was converted into a polyboron compound, and the operating pressure was supplied to the filtration membrane of the reverse osmosis filtration process at 5 to 25 kg / cm 2, thereby containing unfiltered boron compound-containing water. Is discharged after the neutralization treatment, and the filtered water, which is the deboron water filtered with the boron compound below the drinking water standard value of 0.3 mg / l, is sent to the neutralization treatment and hardness adjustment process of producing liquor production water.

Since the influent water flowing into the reverse osmosis process contains little salt, it operates at a low pressure within the range of 5-25 kg / cm 2. In the case of the spiral filtration membrane, the permeate amount of the membrane is operated at 0.6 to 1.2 m 3 / m 2 · day, in which the boron compound is filtered below the drinking water standard value of 0.3 mg / l.

In this reverse osmosis process, even if the pH is supplied in an alkaline state of 9 to ₁₁ , substances such as CaCO ₃ and CaSO _{4 which} generate scales have been removed in the nanofiltration process and reverse osmosis process, so scale generation is a problem. It doesn't work.

Ⅳ. Steps to produce liquor-making water for Cheongju

1. Neutralization and hardness adjustment process

In the neutralization treatment and the hardness adjustment step, acid is injected into the filtered water, which is deboronized, and the pH is neutralized to 5.8 to 8.5, which is the standard for drinking water, while mineral mineralizer or pre-treated deep seawater is supplied to provide hardness of 150 to The treated water adjusted to the 300 mg / L range is sent to a water reforming process.

The acid used for the neutralization treatment is citric acid, tartaric acid, malic acid, malic acid, succinic acid, fumaric acid, EDTA (Ethylene diamine tetra acetic acid) Use one type of acid, such as lactic acid or ascorbic acid, and organic acids that produce complex salts or sulfuric acid.

In the hardness adjustment, the mineral modifier, the deep water of the ocean is selectively removed monovalent salts such as NaCl and KCl in the electrodialysis apparatus or electroextraction apparatus using a monovalent cation selective exchange membrane and a monovalent anion selective exchange membrane, and then Ca / Mg The commercially available product which adjusted mineral balance to the weight ratio of 2-6 is used.

¹⁷ O-NMR Spectrum Half-width of Nuclear Magnetic Resonance (NMR) of Deep Sea Water is 70 면서 and Nuclear Magnetic Resonance ¹⁷ O-NMR Half-width If the value is not treated low, the water reforming step is omitted, and the treated water whose pH and hardness are adjusted in the neutralization and hardness adjustment step is used as the liquor production water.

In order to reduce the manufacturing cost of the liquor manufacturing water, pre-treated deep seawater is injected into tap water with purified water or underground mineral water (including spring water), and the hardness is in the range of 150 to 300 mg / L. The adjusted product may be used as liquor manufacturing water in the cheongju manufacturing process.
