Description

Filter for illite for water treatment

The present invention relates to a filter for water treatment containing an illite. More specifically, the present invention relates to a water treatment filter including an illite that can increase the amount of dissolved oxygen by water treatment by filtering.

In general, most commercial water purifiers use various types of filters to filter foreign substances in the water to make drinking water directly. They filter out foreign substances, especially harmful substances, into drinking water, but they do not increase the dissolved oxygen in the water itself. However, since it does not boil water and makes it possible to drink, the amount of dissolved oxygen is not significantly reduced than boiling water and drinking, but it does not increase the original dissolved oxygen further.

In addition, the conventional dispensers (dispensor) is only to drink more drinking water by heating or cooling the drinking water, etc. already drink, it does not include a filtration means such as a filter, but only water such as a heater or a cooler It is provided only with the means which can heat or cool.

In addition, although some conventional water purifiers are configured to increase the amount of dissolved oxygen in the water by forcibly blowing air into the water by using an air pump or the like to dissolve the oxygen in the water, such as harmful gases in the air In addition, it may be dissolved in water, but rather unsuitable as drinking water, and there are disadvantages such as excessive cost for maintenance and repair due to frequent breakdowns due to the use of an air pump.

It is an object of the present invention to provide a water treatment filter comprising an illite which can increase the amount of dissolved oxygen by the water treatment by filtering.

The water treatment filter including the illite according to the present invention comprises a granular illite and a nonwoven fabric for fixing the illite in a filter case having an inlet and an outlet.

The granular illite has an average particle diameter of 2 to 5 mm.

The nonwoven fabric may be laminated or wound, and the granular illite may be fixed between the laminated nonwoven layers or between the wound layers of the wound nonwoven fabric.

Filtrated activated carbon particles may be further included in the filter.

The nonwoven fabric may be a nonwoven fabric made of activated carbon fibers.

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

As shown in Fig. 1 and Fig. 2, a filter for water treatment comprising an illite according to the present invention includes a granular illite and the illite in a filter case 1 having an inlet 4 and an outlet 5. Characterized in that it comprises a nonwoven fabric for fixing the.

The filter case (1) having the inlet (4) and the outlet (5) in the above can be made of a conventional synthetic resin or the like, the filter case (1) is a non-woven fabric for fixing the illite and the illite As a function of forming a flow path through which water passes while at the same time fixing and encapsulating them, it can be easily understood by those skilled in the art. The filter case 1 may be formed in a cylindrical or rectangular parallelepiped. The inlet port 4 and the outlet port 5 formed in the filter case 1 is an inlet port 4 where the water to be filtered is introduced to function as a filter, and an outlet port 5 where the filtered water flows out. Molding in any form is possible as long as it can be referred to as.

In the present invention, in particular, the illite is employed in the filter to increase the dissolved oxygen amount by the action of the illite.

Illite is a kind of mineral consisting of a main component as shown in Table 1, it was found to have the following physical and chemical characteristics.

Physical characteristics

1. The mineralogy structure has a scaly (mica) three-layer structure, and when absorbed, the interlayer spacing expands to about 1.8Å, and because of the charge of 2 (-), flocculent precipitation due to the electric neutralization of suspended fine particles in the water To significantly improve turbidity.

2. Absorb and decompose various heavy metals.

3. In addition to mica, it is a representative mineral with high aluminum content in mica type clay minerals.

4. It is a fine mica mineral whose main component is alumina silicate. It is a pale yellow powder that does not swell in water and has low base substitution ability.

5. It generates a large amount of negative ions in itself.

6. It emits far-infrared rays that are beneficial to the human body (93% at room temperature).

7. Improve the sensory temperature over 5 ℃ and remove all toxins.

8. Viruses, bacteria, fungi, such as bacteriophages.

9. Its moisturizing effect is great, prevents direct sunlight and has high activity.

10. Adsorb and deodorize toxic gases and odors in the air.

11. It emits a large amount of dissolved oxygen in water and activates water molecules.

Chemical characteristics

Due to the nature of natural inorganic nonmetallic minerals, there is no spontaneous chemical reaction, and it is insoluble in water, organic solvents, acids and alkalis.

It is preferable to use the granular illite having an average particle diameter of 2 to 5 mm. If the particle diameter is too small, less than 2mm, there may be a problem to deviate from the non-woven fabric to fix it in the purified water flow out from the filter case (1), if it exceeds 5mm, there is no problem, but included in the filter case (1) There may be a problem in that the content of the granular illite is relatively reduced to increase the dissolved oxygen increase effect.

The nonwoven fabric may be laminated or wound, and the granular illite may be fixed between the laminated nonwoven fabric layers 2 or between the wound layers of the wound nonwoven fabric so that the illite layer 3 is formed. Lamination of the nonwoven fabric is particularly suitable when a filter case 1 such as a rectangular parallelepiped is used, and the multilayer nonwoven fabrics are cut in accordance with the shape of the filter case 1 and laminated, and the granular illite is interposed between the layers of the nonwoven fabric. Can be fixed. In addition, as shown in Fig. 2, the nonwoven fabric can be wound and used, which is appropriate when the cylindrical filter case 1 is used. The nonwoven fabric can be spread widely to evenly distribute the granular illite thereon, and can be wound into a cylindrical shape while the illite does not lean to either side, and then accommodated in the cylindrical filter case 1. At this time, it may be further fixed by winding with a yarn of synthetic fibers to prevent the illite from pulling out, and to prevent the wound nonwoven fabric from being loosened. In addition, it will be easily understood by those skilled in the art that other techniques for evenly distributing and fixing the illite on the nonwoven fabric may be used to uniformly distribute the illite in the filter case 1.

Filtrated activated carbon particles may be further included in the filter. These activated carbon particles are known to adsorb foreign substances in water purification, to adsorb and decompose chlorine gas for disinfection, and to sterilize, and the same or similar to those used for water purification in commercial water purifiers. It can be used for the purpose.

In particular, in the present invention, the activated carbon particles may be used separately with the illite, but the nonwoven fabric is used as a nonwoven fabric made of activated carbon fibers, and thus the nonwoven fabric immediately adsorbs foreign matters and the nonwoven fabric itself adsorbs foreign substances. It can adsorb and decompose chlorine gas and sterilize it.

Hereinafter, preferred embodiments and comparative examples of the present invention will be described.

The following examples are intended to illustrate the invention and should not be understood as limiting the scope of the invention.

Example 1

Evenly distribute 160 g of granular illite having an average particle diameter of 3 mm on a 250 mm wide and 750 mm long rectangular activated carbon fiber nonwoven fabric having a nitrogen specific surface area of 1,300 to 1,400 m ² / g and an iodine number of 1,000 to 1,100, After winding the activated carbon fiber nonwoven fabric in that state, the outer surface of the wound nonwoven fabric was wound and fixed to prevent the illite from slipping out. A fixed cylindrical nonwoven fabric was introduced into the cylindrical filter case 1 as shown in FIG. 1 to complete the water treatment filter including the illite according to the present invention.

The amount of dissolved oxygen of the water before passing through the manufactured water treatment filter and the amount of dissolved oxygen of the water after passing through the prepared water treatment filter were measured.

The water used in the experiment was collected from groundwater and Daecheongho in Seosan-si, Daecheongho, and purified. It is shown in Table 2 below.

The test method of dissolved oxygen amount was as follows.

First, 201 ml of water as a sample is added to the Erlenmeyer flask, and 0.5 ml of manganese chloride (MnCl ₂ ) solution (1 M concentration) and 0.5 ml of potassium iodide (KI) solution (0.5 M concentration) are added thereto. 2 ml of 1 M concentration is added and shaken sufficiently. When the precipitate is dark brown, 5 to 7 drops of starch solution (regardless of concentration) are added. If blue color appears, titrate with sodium thiosulfate solution (0.1 M concentration) using a pipette until this blue color disappears, and then calculate the dissolved oxygen amount by the following Equation 1.

[Equation 1]

Dissolved oxygen (mg / ℓ) = 8 * N * 1000 * (η / v -1)

Where N is the normal concentration of sodium thiosulfate solution, η is the volume of sodium thiosulfate solution used for titration, and v is the amount of water (201 mL) transferred to the Erlenmeyer flask.

As shown in Table 2, irrespective of the type of intake source, it was confirmed that the dissolved oxygen amount of the water before passing through the water treatment filter according to the present invention and the dissolved oxygen amount of the water after passing through were significantly different. It was confirmed that the amount of dissolved oxygen increased significantly. It can be seen that, regardless of the amount of dissolved oxygen contained in the original water or the water according to the intake source, the amount of dissolved oxygen is greatly increased only by passing through the water treatment filter according to the present invention.

Therefore, according to the present invention, there is an effect of providing a water treatment filter including an illite which can increase the dissolved oxygen amount by the water treatment by filtering, and the dissolved oxygen amount only by passing through the water treatment filter according to the present invention. This has the effect of greatly increasing.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such modifications and modifications are within the scope of the appended claims.
