First of all, when examining the characteristics of deep sea water, deep sea water is generally called deep sea water deeper than 200m from sea level, and unlike surface sea water, sunlight does not reach, so plankton and life cannot proliferate. Therefore, due to the high concentration of nutrients and the density difference according to the water temperature, there is no contaminant present in the surface seawater because it is not mixed with the surface seawater, and low temperature stability, pollutants, harmful bacteria, Very low purity of organic matter, rich in inorganic nutrients, which are very important for plant growth, mineral balance and various mineral components in a good balance For many years, the cluster of water molecules is small grouped and matured with water with good permeability due to low surface tension. It has characteristics such as mature ripening.

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. More than 70 major elements such as calcium, magnesium, iron, zinc, sodium, etc., required for the growth of fermented microorganisms, as shown in Table 1 "Analysis Value of Deep Seawater and Superficial Seawater" without containing any harmful bacteria. Nutrient, viable count, and water temperature have a considerable difference, as it contains various minerals.

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, and the deep sea water contains 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 number of viable bacteria, such as (pathogenic) microorganisms, chlorella, etc., is small, from one tenth to one hundredth of surface water.

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 of 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.

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. .

The deep sea water has the same characteristics as above, but in order to use the food for cooking water, excess salts are removed, and water adjusted with hardness of mineral adjuster or deep sea water is used as water for processing food.

The deep sea water contains boron compounds in the range of 4 to 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.

Hardness adjustment in the hardness adjustment process is performed by selectively removing monovalent salts such as NaCl and KCl from an electrodialysis apparatus or an electroextraction apparatus using a monovalent cation selective exchange membrane and a monovalent anion selective exchange membrane in the deep ocean water, and then Ca / Use a commercially available mineral modifier with a mineral balance adjusted to a weight ratio of 2 to 6 or use deep sea water.

The present invention will now 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

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, a sulfate ion (SO ₄ ^{2 -)} is the cause of membrane blockage if carried out by a subsequent primary desalination in reverse tuyeogwa device, electrodialysis device or an electric ejectors deep sea water to remove the first desalting step Send to.

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 consists of 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 or one side of the membrane from the dense layer, or a dense layer of such an asymmetric membrane. A composite membrane having a very thin separation 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 -> and SiO _2, a sulfate ion (SO ₄ ^{2 -),} if the 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%. In the case of spiral, the membrane permeate amount is 0.7 to 1.4 m 3 / If m 2 · day, the membrane permeate amount is 70 to 80% of the inflow rate.

After warming the deep sea water as shown in Table 1 at 25 ° C and pretreating the FI value to 3.2 by ultrafiltration, the model number of the cross-linked polyamide material of Toray Industries, Ltd., Japan The membrane permeate was 80% of the influent when the pressure was supplied to the membrane at 20㎏ / ㎠G using SU-610's spiral nanofiltration membrane and the membrane permeate was 1.2㎥ / m². Analysis of the main components of the sulfate-containing water and the filtered desulfurized ion mineral water is shown in Table 2.

As shown in Table 2, nanofiltration of deep sea water resulted in almost no removal of boron compounds, 28.5% Na, 41% calcium (Ca), and 35% magnesium (Mg). More than 90% of sulfate ions were removed.

Ⅱ. Desalination Stage

The deep seawater treated in the pretreatment filtration process may be subjected to primary desalination by reverse osmosis filtration, electrodialysis, electroextraction, freezing, evaporation or condensation, or ion exchange, but evaporation and condensation Since the exchange process is not economical, in the present invention, the primary desalination treatment is performed by one of a reverse osmosis filtration process, an electrodialysis process, an electroextraction process, or a freezing process, and then the process is sent to the pH adjusting process of the second desalination process.

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 99.85wt%. 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

The deep sea water filtered in the pretreatment filtration process is supplied to a cooling device with a built-in insulated cooling coil, and when the deep sea water is cooled, it is shown in FIG. 3 "Phase equilibrium diagram of H ₂ O-NaCl system according to freezing of deep sea water." As you can see, when the coolant is circulated through the cooling coil from the freezer to cool the temperature of the water in the chiller and becomes below -2 ° C, sherbet ice begins to be produced and the temperature is -22.40 ° C. Until the concentration reaches a process point of 26.285wt% (also called Cryohydric point), sorbet ice is produced with low salt content. 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.

The desulfurized ion mineral saline, the filtrate filtered in the nanofiltration of Example 1, was a crosslinked polyamide-based composite membrane in a high pressure reverse osmosis membrane of Toray Industries, Ltd., Japan. The membrane permeate was 52% of the influent when the membrane permeate was 0.72㎥ / ㎡ · day using a spiral reverse osmosis membrane of model number SU-810 and the pressure was supplied to the membrane at 60㎏ / ㎠G. Analysis of the main components of the demineralized and brine concentrated brine is shown in Table 3.

Analysis of Principal Components of Demineralized Water and Unfiltered Brine in Reverse Osmosis  Item  Influent Water (Desulfurized Ion Mineral Salt)   Filtered demineralized water Concentrated brine      pH        7.24        7.20        7.28 Na ⁺ (mg / L)    9,650       38.7    20,063 Cl ^- (㎎ / ℓ)   17,300       71.6    35,478 Ca ^{2 +} (㎎ / ℓ)      338        0.6       703 Mg ^{2 +} (㎎ / ℓ)    1,060        1.9     2,206 K ⁺ (mg / L)      355        1.7       737 _{^{SO 4 2 - (㎎ / ℓ}} )      319        3.7     1,584  B (mg / L)        4.1        1.8         6.6

As shown in Table 3, most of salts were removed highly by 99% of deep seawater in reverse osmosis, but the boron compound alone was only 1.8mg / l and the removal rate was very low, below 80%. Since it is doubled, it cannot be used as cooking water for food by itself.

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, with an ion radius of 0.23 단순한, so that simple nanofiltration and reverse osmosis 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 There is a problem that the treatment is difficult to drink less than 0.3mg / ℓ by electrodialysis and electroextraction. In addition, the freezing method also has a problem that it is difficult to treat the drinking water below the standard value of 0.3 mg / ℓ, so that the boric acid is converted to a poly boric acid in the gel state by treating the pH with an alkali of 9-11. It is then sent to a reverse osmosis filtration process 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 under the boron compound of 0.3 mg / l, which is the drinking water standard, is sent to the pH and hardness adjustment process of producing cooking water.

Since the influent flowing into this reverse osmosis treatment process contains little salinity, the operation pressure should be operated at a low pressure in the range of 5 ~ 25㎏ / ㎠. 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.

In the reverse osmosis filtration step of Example 2, the demineralized water, which was filtered water, was adjusted to pH 9.5 in a pH adjustment step to convert the boron compound in the form of polyboric acid, followed by Toray Corporation of Japan. Low pressure reverse osmosis membrane of model No. SU-710 using spiral reverse osmosis membrane, the pressure was supplied to the membrane at 20㎏ / ㎠G and the membrane permeation amount was 0.72㎥ / ㎡ · day. %, And the concentration of boron (B) in the filtrate (deboron water) was measured to 0.12 mg / l, which was treated to 0.3 mg / l or less of the boron reference level of the beverage, so that it could be used as cooking water in cooking of food. .

IV. Steps to Produce Cooked Water

1. pH and hardness adjustment process

In the pH and hardness adjustment process, the treated water is adjusted by adjusting the hardness to 30 to 1,000 mg / L by supplying mineral adjuster or raw water of deep sea water while injecting acid to adjust the pH to 5.8 to 8.5, which is the standard for drinking water. Water is used in the cooking process.
