TECHNICAL FIELD [0001] The present invention relates to an osmotic pressure-inducing substance, a tablet separator containing the osmotic pressure-inducing substance, and a separation device using the osmotic pressure-

The present invention relates to an osmotic pressure-inducing substance for purifying contaminated water, a separation membrane containing the same, and a separation apparatus using the same. More particularly, the present invention relates to a substance capable of purifying contaminated water, And a separation device using the same.

As the world's population grows and the pollution increases due to the development of the industry, the global water shortage is steadily increasing.

Especially in less developed countries such as Africa and Southeast Asia, the water available for drinking water is getting smaller and more frequent due to people drinking polluted water.

In Africa, extreme droughts and water shortages caused by heat waves have become a global phenomenon, and various relief organizations such as UNICEF, KAF, and Good People have provided relief and well digging projects due to water shortages. It is progressing. Another problem with water shortages is that UNESCO reports that 20% of the world's population can not drink clean water and 2.6 billion are exposed to unsanitary conditions without basic sewage treatment facilities.

In fact, even if a lot of water-scarce countries (northeastern Africa, Southeast Asia, etc.) suffers extreme water shortage, and there is no special water purification facility even if water is sought, the water quality is seriously polluted and malaria occurs as a parasitic larva to the reservoir. The parasite infects the skin and can infect the guinea larvae. These germs can penetrate the flesh, cause death or cause blindness.

Many people suffer from water-borne diseases such as diarrhea, cholera, typhoid, etc., because they drink water without the need for separate purification. Thousands of people die every year due to dirty water, and even though they know it is dangerous, It is inevitable to drink the contaminated water with determination to die.

There are a variety of diseases that can occur when drinking contaminated water, such as Typhoid, Enteritis, Giardiasis, Cholera, Vibrio septicemia, Hepatitis A, Shigellosis, Salmonellosis, And amebiasis.

In addition, in lakes and other highlands such as Africa and Southeast Asia, carcinogenic substances such as arsenic (As) are also contained.

Currently, there are equipment that can purify polluted water by current science and technology, but local people who drink direct polluted water due to expensive equipment have no choice but to drink polluted water directly.

Further, in the case of the separator and the separator for separating contaminants from the polluted water, a driving force is required for operation of the apparatus, and most of the power supply is necessary. However, there are areas where power supply is not easy, and it is necessary to use driving force other than electric power.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. First, it should be noted that, in the drawings, the same components or parts have the same reference numerals as much as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

The terms " about ", " substantially ", etc. used to the extent that they are used herein are intended to be taken to mean an approximation of, or approximation to, the numerical values of manufacturing and material tolerances inherent in the meanings mentioned, Accurate or absolute numbers are used to help prevent unauthorized exploitation by unauthorized intruders of the referenced disclosure.

The present invention relates to an osmotic pressure-inducing substance for a pollution-controlling agent, a tablet separating membrane containing the same and a separating apparatus using the same, wherein the osmotic pressure-inducing substance for a pollution-controlling agent is mixed with starch and a biodegradation enzyme.

Further, the purified separation membrane is characterized in that a substance in which starch and biodegradation enzymes are mixed is adhered and formed on one side of the separation membrane.

Further, the separation device for the polluted water purification agent comprises a container having a space therein and a purification membrane for partitioning the space.

1 is a schematic perspective view of a purification membrane according to an embodiment of the present invention.

The tablet separator 100 has a separation membrane 110 and an osmotic pressure-inducing material 120 formed on one side of the separation membrane. The osmolality-inducing substance 120 has a mixture of starch and biodegradable enzyme.

The separator 110 may be formed of a material selected from the group consisting of cellulose acetate, cellulose triacetate, polyamide, polyimide, polyethersulfone, polyamideimide-polyethyleneimine, and the like. ≪ / RTI >

The thickness of the separation membrane 110 is preferably 100 to 200 mu m, and the pore size is preferably 1 nm or less.

In general, when separating water using a membrane having a pore size of 1 nm or less, it is meaningless to separate water because there is little water passing through the membrane without additional driving force such as pressure or osmotic pressure.

However, when the osmotic pressure-inducing substance 120 is attached to one side of the separation membrane, the osmotic pressure is generated, so that water purification can be performed by the positive osmosis process, and a large amount of water can be purified.

The purification technique of water by the positive osmosis method does not use electricity, and it is a technology that can remove contaminants in the molecular unit. The purification technique of the water by the positive osmosis method uses a draw agent to have a higher osmotic pressure than the supply water (raw water), and the osmotic pressure inducing material 120 serves as an inducer.

When the inductive material is placed on the opposite side of the space where the supply water is located with the separator interposed therebetween, the intermembral osmotic pressure difference occurs and the water moves. That is, a driving force is required when the purified water passes through the membrane, and the positive osmosis method uses a difference in osmotic pressure across the membrane as a driving force.

Since the osmosis method uses a membrane having a very small pore size of 1 nm or less, it removes various contaminants larger than the pore size and induces the purified water to permeate through the membrane.

The osmotic pressure of the osmotic pressure-inducing substance on the product water side should be higher than the osmotic pressure of the feed water in order that the direction of permeation of the purified water is directed from the feed water to the production water.

The movement of the water moves from one side of the separation membrane to one side to which the osmotic pressure-inducing substance 120 is attached by the forward osmosis method.

The osmotic pressure is increased due to the osmotic pressure-inducing substance attached to one side of the separation membrane, and water can be permeated to the side to which the osmotic pressure-inducing substance 120 is attached from the other side of the separation membrane due to the increased osmotic pressure.

At this time, pollutants can not permeate and only water moves. And only the water is permeable through the membrane, and the water permeates only through the water, which is present in the contaminated water, such as Typhoid, enteritis, Giardiasis, cholera, Vibrio septicemia, hepatitis A, Shigellosis, Salmonellosis, (Amebiasis) and the like, as well as the small size of arsenic (As), such as carcinogens can not penetrate.

The osmolality-inducing substance 120 is mixed with starch and biodegradable enzymes. The type of the starch is not particularly limited and may be any substance that can be ingested by human consumption.

The starch may be an uncooked, raw sweet potato, a fresh potato, a flour or the like, and may be used as a mixture of water and boiled water. If it is used as a raw material, it can be well mixed with the biodegradable enzyme and adhere well to the membrane. Non-limiting examples of the starch include cooked rice, boiled sweet potatoes, and boiled potatoes.

In addition, the biodegradable enzyme is preferably a saliva.

When the starch and the biodegradable enzyme are mixed, the starch is decomposed and decomposed into the disaccharide.

The disaccharide may induce high osmotic pressure as compared with the case of using only starch, so that the intermolar osmotic pressure difference between the membranes increases, and thus the permeation amount of a large amount of water can be induced.

Assuming that the same weight is used, the molecular concentration of the disaccharide having a relatively low molecular weight is much higher than that of the starch, and the concentration of the molecule is proportional to osmotic pressure by Van Hoff's equation.

Preferably, the starch and the biodegradable enzyme are mixed in a weight ratio of 90:10 to 97: 3. When mixed in the above range, the membrane is well adhered to one side of the separation membrane, and the starch can be decomposed well by biodegradation enzymes.

When the water passes through the separation membrane, the osmotic pressure-inducing substance may be dissolved in the water by being brought into contact with the osmotic pressure-inducing substance of the present invention. Since the dissolved osmotic pressure-inducing substance 120 is directly consumable by a person, it is not necessary to remove the osmotic pressure-inducing substance 120 through an additional separation process.

Figures 2 and 3 show cross-sectional views of a separator according to an embodiment of the invention. 4 is a photograph showing a separation apparatus according to another embodiment of the present invention.

2 shows the state before the contaminated water is separated by putting the contaminated water into the separation apparatus. FIG. 3 shows a state in which the contaminated water is separated after putting the contaminated water into the separation apparatus.

The separating apparatus according to the present invention may comprise a container having a space formed therein and a tablet separator (100) for partitioning the space.

The tablet separator is the same as the tablet separator described above, so a detailed description thereof will be omitted.

The container 200 is not particularly limited, and it is sufficient that there is a space that can receive the contaminated water and a space that can receive the purified water through the separated water. In addition, the container may be applied without limitation to a container other than the separation membrane, which does not allow water to enter or wash through the wall of the container.

The walls of the container may be of rigid rigidity or of a soft form commonly referred to as a plastic bag. The container may be made of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyester (PES) or the like.

The inner space of the container is divided into two or more by the separation membrane, and the two or more divided spaces are not communicated with each other, and the movement of water can be moved only through the separation membrane. This is to prevent the contaminated water from entering into the space where the purified water exists when the contaminated water is purified through the membrane.

Further, the separating apparatus of the present invention can be opened and closed at the upper part.

Referring to FIG. 4, the container is formed in a soft shape, and the upper portion can be opened and closed and can be made in a zipper shape. The inside of the vessel is provided with a purification membrane for partitioning the space, and the water can be purified through the purified membrane by adding the contaminated water in one space (indicated as "front"

The water in the contaminated water is moved to another space (labeled "back" in FIG. 4) through the purified separator.

When the contaminated water is separated through the separator, the water collects in the space opposite to the contaminated water. Since the contaminated water is removed, the water becomes a drinkable water. If the user drinks the same straw as shown in FIG. 4 It is possible to minimize the case where the water in the space containing the polluted water falls to the opposite side.

Hereinafter, embodiments of the present invention will be described in detail.

Example  One

To prepare the starch, the rice was put together with water and heated to make rice. As a biodegradation enzyme, saliva was prepared and mixed with rice, and the rice was well kneaded to produce an osmotic pressure-inducing substance by mixing well the saliva and rice. The mixing ratio was a ratio of rice (starch): saliva of 95: 5 by weight.

A purified membrane was prepared using the osmotic pressure-generating material thus prepared, and a polymer polyamide was used as a separation membrane. A membrane having a thickness of 200 μm and a pore size of 1 nm or less was prepared. The osmotic pressure-inducing substance, which is a mixture of rice and saliva, was attached to one side of the separation membrane to a thickness of about 3 to 5 mm. At this time, sticking can be adhered well due to stickiness of rice.

On the other hand, a polyethylene resin was used as a container to prepare a container for the production of a separator, and a space was formed in the polyethylene resin, and the tablet separator prepared in the above was installed so as to be divided into two spaces, Respectively.

Experiments were conducted for 24 hours to purify water through separator by adding arsenic (As) to tap water to conduct water purification experiments using the separator manufactured.

The tap water containing arsenic (As) was placed in a space where the osmotic pressure-inducing substance did not adhere, and water was observed to move to another space.

Comparative Example  One

The procedure of Example 1 was repeated,

Separating apparatus was prepared in the same manner as in Example 1 except that salted rice was not mixed with rice (starch), and rice seaweed was attached to one side of the separating membrane to prepare a purified separating membrane. For 24 hours.

Comparative Example  2

The procedure of Example 1 was repeated,

Polymer polyamide was used for the separation membrane alone without using the osmotic pressure inducing substance. The separation apparatus was prepared in the same manner as in Example 1, and an experiment for separating tap water containing arsenic (As) was conducted for 24 hours.

5 is a graph showing a flow rate rate through the separation membrane of Example 1. FIG.

As a result of separating the water through the purified separator according to the present invention for 24 hours, there was not much decrease in the flow rate with time, and it showed a flow rate of about 0.5 L / m 2 · h after 24 hours. After 24 hours of separation, the membrane is washed and then the osmotic material is attached to one side of the membrane. When the water is purified again, it is restored to the original flow rate (indicated as 2nd in the graph). From this, it can be seen that the separator can be recycled, and it is expected to be able to be used a plurality of times.

FIG. 6 is a graph showing the average flow rates through the membranes of Examples and Comparative Examples. FIG.

Referring to FIG. 6, it can be seen that the average flow rate with time is obtained through the purification membrane. When purifying water using the purification membrane according to the present invention, a large amount can be purified, while osmotic pressure- , Or attachment of other materials (starch only) could not confirm that the water was completely or substantially not separated.

In Example 1, arsenic was added to tap water to pass through a separation membrane. The arsenic content was about 1 nm in size because of its fine size. The fact that such a small amount of arsenic does not pass through the membrane can be interpreted that other pathogenic bacteria do not pass through the membrane.

As a result of confirming whether or not the separation membrane of the arsenic of Example 1 was passed, it was confirmed that a maximum of about 86% was removed.

From this, it was confirmed that a considerable part of the contaminated water can be purified by drinking water.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be clear to those who have knowledge of.
