Water purifier

The present invention relates to water purifiers such as beverages, and in particular, by immersing in water of a water purification plant, it exhibits a bactericidal effect, transfers water to alkalinity, and is a high quality mineral water in which chlorine, heavy metals and impurities are adsorbed and removed. It relates to a water purification agent that can be made.

In recent years, as water pollution in rivers and the like progresses, in order to use this as tap water, more and more chemicals have been used for the purpose of removing contaminants and sterilization. For example, in a water purification plant, organic matters are precipitated with alumina as a filter agent and chlorine is used as a disinfectant, and chlorine is used as a disinfectant. However, raw water is acidified due to the use of these chemicals, which results in redness in water pipes. There arises a problem that rust is generated and the water pipes are corroded.

In order to prevent corrosion of such water pipes, caustic soda, soda ash, and calcium carbonate are generally used to alkalinize raw water. However, since these caustic soda and the like are highly irritating and have a severe action on skin and other animal tissues, they may cause hand breaks and the like, and especially the residents near the water purification plant suffer more damage.

SUMMARY OF THE INVENTION An object of the present invention is to provide a natural water purification agent which is safe and has various water purification functions and also has a bactericidal action different from water pipe corrosion inhibitors such as caustic soda and soda ash of the conventional example.

MEANS TO SOLVE THE PROBLEM In order to solve the said problem, the present inventors substituted various water pipe corrosion inhibitors, such as caustic soda, and the coral sand obtained from the raw skeletal structure of fossil coral and fossil group, water, Can be converted into an alkaline phase to form a delicious mineral water, and not only adsorption and removal of chlorine, heavy metals and impurities, but also sterilizes water from its own bactericidal effect of Coral Sand to replace the conventional water purification agent of chemical compounds It discovered what can be used as a water purifier to make, and came to complete this invention.

Coral sand is referred to in the present invention, the coral sand obtained by the production skeleton or hwaseokgun of one trillion seconds coral, as shown in Table 1, and calcium carbonate as the main component (CaCO _3, about 95%) by significant biological component, magnesium, strontium Contains traces of iron, copper, zinc, manganese, cobalt and chromium, including sodium, potassium, phosphorus and chlorine.

Table 1 (Composition table of coral sand)

These elements accumulate and weathered by the life activities of the tonic coral.

Therefore, unlike other water purifiers obtained by chemical treatment, it has an ecological chemical structure and is safe for the human body. Moreover, since calcium carbonate is the main component, it has the effect of alkalizing water. There is no harm.

When coral sand explains the process of removing chlorine, since coral sand is mainly composed of calcium carbonate, neutralizing acid (H ₃ O ⁺ ) liberated in the process of chlorination of raw water, as shown in the following equation, Parts by calcium ions (Ca ^2+), chloride (Cl ^{- -)} and bicarbonate ion (HCO _3).

When each reaction formula from (1) to (4) is aggregated, it is a result shown in Formula (5).

Therefore, the water containing chlorine with quicklime smell is deodorized by the coral sand, and at the same time, the pH of the raw water is shifted to the alkaline side due to the by-product bicarbonate ions, and contains a large amount of calcium ions, and high quality mineral water is obtained. .

In addition, calcium of calcium carbonate, which is a major component of coral sand, is replaced with heavy metal ions in water to form calcium ions, and heavy metals become poorly soluble carbonates, which are adsorbed and removed by the fine pores of coral sand.

In addition, fine pores develop by heating to increase the surface area, thereby adsorbing and removing impurities in the water.

In addition, it was found that the coral sand, which is the object of the water purifying agent of the present invention, has an bactericidal effect by itself.

In order to prove this effect, the results of applying the test to Chibasei Asei Junior College were as follows.

First, the E. coli plate was partially sprayed with Coral Sand, which is the subject of the present invention, and only the portion sprayed with Coral Sand showed an effect of inhibiting E. coli growth.

Next, the coral sand was sprayed on the front, and the effect of preventing the growth of E. coli was evident throughout.

As a result of this experiment, it was found that coral sand, which was never thought of as a bacterial agent, clearly has an effect of inhibiting the growth of E. coli and can be used as a natural antibacterial agent.

In addition, by attaching silver to the coral sand can further increase the bactericidal effect, the coral sand of the present invention can fully exhibit the effect as a preservative without attaching silver.

Coral sand, which is the object of the present invention as described above, may be immersed in the raw water of the water purification plant, but in order to further enhance the effect thereof, it is preferable to fill the filter with water and pass the raw water. Of course, it can also be used as a household water purifier.

The water purification agent of this invention can be manufactured as follows. In order to provide a water purifying agent having an effective bactericidal action, it is possible to first prepare a coral sand obtained by washing with water to remove salts and impurities, and then heat disinfection, drying and activating at a temperature of 80 to 150 ° C. By treating as described above, the coral sand is activated by removing impurities such as salt and organic animals, and developing fine pores of 10 microns or less and increasing its surface area.

When the raw water is purified by contacting the coral sand obtained by treatment as described above, the chlorine odor of the raw water is deodorized, and the raw water is not only alkaline but also provides high quality minerals to the raw water. In addition, calcium, which is a major component of coral sand, is replaced with heavy metals, and heavy metals are removed by adsorption of heavy metals into the fine pores of coral sands. In addition, the coral sand treated as described above exhibits an effective bactericidal action, which is the most characteristic part of the present invention, and exhibits sufficient effects as a preservative even without attaching a component that exhibits a separate bactericidal effect such as silver, and thus, a conventional chemical substance And will provide a natural cleanser that is safe for the human body.

Coral sand treated according to the present invention can be used as a water purifier for drinking water by putting it in a cartridge such as water purifiers for home and business, and used as a water purifier for drinking water by putting it in cartridges for domestic and commercial water purifiers in combination with activated carbon or hollow fiber membranes. It may be. In addition, to remove salt and impurities by washing the natural coral sand, and to prepare the coral sand obtained by heat sterilization, drying and activation at a temperature of 80 to 150 ℃ to a particle size of 10 to 100 mesh, cartridges for household and commercial water purifier It can be used as a water purifier for drinking water by placing it in the water, and can also be used as a tea bag type water purifier of about 3 g to 30 g.

The present invention is summarized as follows.

(1) Calcium carbonate, which is a major component of coral sand, elutes and transfers the raw water to weak alkalinity, so that the pH is optimal as a drink.

(2) At the same time, calcium carbonate eluted from the coral sand neutralizes the chlorine in the raw water used for sterilization, and the smell of quicklime disappears.

(3) Minerals such as calcium and magnesium contained in the coral sand are gradually eluted to become a high quality mineral water, which is effective as a source of supply of elements necessary for the human body.
