Abstract

THE SUBJECT OF THE PRESENT INVENTION IS A WATER PURIFYING AGENT. ACCORDING TO THE INVENTION, CORAL SAND OBTAINED FROM LIVE CORAL SKELETS FORMING REIFS ARE USED AS A WATER PURIFYING AGENT. APPLICATION: CORAL SAND IMMERSED IN WATER PRODUCES A POWERFUL BACTERIOSTATIC EFFECT AND AT THE SAME TIME MOVES THE PH OF THE WATER TOWARDS ALKALINE MEDIA; GOOD QUALITY MINERAL WATER IS OBTAINED. FURTHER, THE CORAL SAND OF THE PRESENT INVENTION HAS NO HARMFUL EFFECT ON THE HUMAN ORGANISM.

Description

The present invention relates to a water purification agent for

  drinking water and the like. The water purifying agent, which is immersed in water in a tank as is the case in a filtration plant, produces a bacteriostasis and displaces the pH of the water to the alkaline media so that the water

  becomes a mineral water of good quality.

  In recent years, water sources have been contaminated by various agents such as chemicals, bacteria, other microorganisms, etc., due to excessive pollution by industrial residues, etc., and large amounts of chemical substances are used during the purification of water so

  avoid or eliminate this contamination.

  For example, in a filtration station, aluminum sulphate, etc., is used as the filtering medium for precipitating

  organic substances and chlorine as a bactericide for

  keep the water safe from contamination. The use of these chemical agents, however, causes problems, including the fact that the water becomes acidic. Acidic water attacks and rust

  pipelines used for the transport of water.

  To avoid this attack, it is widely used caustic soda, soda lime, calcium carbonate, etc., to move the pH of the water to the alkaline media. However, chemicals such as caustic soda have a strong stimulating effect on the skin and other tissues and cause severe damage to them, causing cracks and so on. In particular, the neighbors of a filtration plant suffer from

these effects.

  An object of the present invention is to provide a natural water purification agent which is safe and has a bacteriostatic effect and which is very different from

  conventional anticorrosion agents for distribution pipelines

  water, such as caustic soda and soda lime.

  According to the present invention, coral sand is used in the purification of water. The coral sand of the invention is obtained from living coral skeletons

reef trainer.

  The inventor has carried out various experiments in order to solve the above problems and found that coral sand obtained from live reef-forming coral skeletons can be used as another anticorrosive agent for tap water pipes. because it is able to move the pH of the water towards the alkaline medium so that the water becomes a mineral water of good quality, and because it also produces

a bacteriostatic effect.

  As shown in Table 1, coral sand contains about 95% by weight of calcium carbonate as the main constituent and also contains magnesium, strontium, sodium, potassium, phosphorus and chlorine which are essential constituents for the body. The remaining constituents are traces of inevitable inorganic elements such as iron, copper, zinc, manganese, cobalt, chromium, etc. We will now describe how the coral sand moves the pH of the water towards the alkaline medium. Calcium carbonate, the main constituent of coral sand, neutralizes the acid (H0 +) that is produced during the sterilization of water by chlorine,

  so that there is production of calcium ions (Ca 2+), bicarbonate ions

  Bonate (HC03) and chloride ions (Cl) as indicated by the following equations: Cl2 + H2O> HCl + HCIO ................. (1) HCl + H2O> H30 + Cl.

  .............. (2) + HCIO + H20> H30 + Cl + (O) ....... (3) .. DTD: 2 3

  2CaCO + 2H30 ----> 2Ca2 + + 2HCO - + 2H20 .... (4)

33 3 2

  Cl + H20 + 2CaCO3 2Ca2 + + 2HCO3 + 2Cl + (O) t (5)

2 2 3 3.

  As can be seen from the equations above,

  water that contains chlorine and therefore smells of chlorine is

  dyed by the coral sand and the pH of the water is shifted to the alkaline media so that there is a large amount of ions

  calcium. As a result, a good tasting mineral water is obtained.

  In addition, it has been found that coral sand itself has a

bacteriostatic effect.

  In order to confirm that the coral sand has a bacteriostatic effect, the inventor carried out tests by the Chiba Hygiene College, the results of which are as follows: A substrate was prepared and colibacilli (colonic bacilli) were placed therein . Then, the coral sand of the present invention was dispersed over a portion of the surface of the substrate. As a result, the bacteriostatic effect was observed only on the portions of the surface where the coral sand had been placed (see

Figures 1 and 2).

  In another test, we covered the entire surface

  of the substrate by coral sand: the bacteriological effect has been observed

  static over the entire surface (see Figure 3).

  In the accompanying drawings, FIG. 1 shows a photograph showing the result of a test in which colibacilli were placed on a substrate and the coral sand of the present invention was then dispersed.

  invention on a part of the surface of the substrate.

  FIG. 2 represents a photogram of an enlarged portion of the surface shown in FIG. 1. As can be seen in FIGS. 1 and 2, the bacteriostatic effect is observed only on the portions of the surface where the coral sand had been

scattered.

  FIG. 3 represents a photograph of the result of another test in which two substrates have been prepared, one being covered over its entire surface with coral sand and the other not being covered with coral sand and both substrates were allowed to stand for 30 minutes. In the photograph, the substrate covered by the coral sand is on the right and the uncovered substrate is on the left. The bacteriostatic effect is observed on

  the entire surface of the substrate covered by coral sand.

  The results of the above tests and other tests reveal that the coral husk, which until now has not been known to be useful as bacteriostatic, effectively inhibits the spread of E. coli, and as a result, it has been found that he

  is useful as a natural bacteriostatic.

  In addition, although the bacteriostatic effect of coral sand can be improved by depositing silver on coral sand, it gives an appropriate effect for potash water and even without

this money.

  As described above, the effect of coral sand can be achieved by simply immersing in water in a filtration station. Increased effect can be achieved by passing water through a filter filled with coral sand. Of course, the coral sand of the present invention can also be used

for domestic applications.

  The process for the preparation of the

  coral sand of the present invention.

  The coral sand of the present invention may be living coral. Alternatively, it may be obtained by washing the live coral sand to remove some salt and then drying the demineralised coral sand at either a temperature in the range of 70 to 190 ° C or in a nitrogen atmosphere. . The fine particles of coral sand thus obtained have innumerable pores and are very soluble, so that they are considered as a bacteriostatiaue very appropriate given their effect of alkalinization of water and their

bacteriostatic effect.

  The effects of the coral blade of the present invention are as follows: a. Calcium carbonate, the main constituent of coral sand, dissolves in water by displacing the pH of the water slightly towards the alkaline medium. As a result, the pH

  water becomes suitable for drinking water.

  b. At the same time, the dissolved calcium carbonate neutralizes the residual chlorine present in the water when chlorine has been added to the water as a bactericide, so that

the water is deodorized.

  c. The constituents of coral sand other than calcium carbonate are gradually dissolved in water, so

  water becomes a mineral water capable of efficiently

  the elements that are indispensable to the human body.

  d. In addition, coral sand inhibits the development of

  coli bacteria and prevents stagnation of water.

  It is understood that the invention is not limited to

  preferred embodiments described above as illus-

  tion and that the person skilled in the art may make various modifications

  tions and various changes without departing from the framework and

of the spirit of the invention.
