The worsening of the water quality caused by the excessive inflow of nitrogen or phosphorus, which is contaminated organic matter in stagnant water bodies such as lakes and rivers, is called eutrophication. The nutrients of such eutrophication are ammonia, nitrite, nitrate, organic nitrogen compound , Inorganic phosphates, organophosphates, silicates, etc. These are mainly introduced into rivers or the sea by domestic sewage, factory wastewater, fertilizers or organic materials. Green algae phenomenon refers to a phenomenon in which the green algae, which are phytoplankton, are greatly increased in eutrophic lakes or slow-flowing streams, and the water is changed to green. Especially, in Korea, as a part of the 4 major rivers development project, due to low water depth, the water flow rate is slow, causing the green algae phenomenon every year, causing damage such as the death of fishes and the like.

In addition, the red tide phenomenon occurring in the southern coast of Korea is a coastal area where geographical endurance is low and seawater exchange with the appearance is minimal, and the development of coastal cities has resulted in the rapid introduction of pollutants such as various industrial wastes, Of course, causing serious damage to coastal fishes. It is called red tide in the sense that water is red, but the colors such as orange, reddish brown, and brown can be changed variously depending on the color of plankton. Phytoplankton such as diatom and dinoflagellate are the most common plankton causing red tides. In Korea, green loess or red tide is sprayed with loess, which is a coagulant spraying agent. However, not only is efficiency in removing rust trough low, but also it is pointed out that there are problems such as high cost of treatment as well as damage to forests for securing loess with continuous use.

The elvan stone used in the present invention has been recorded in Dongwoo-Bokwon, etc. as a record that it has been used as an anti-inflammatory agent for various skin diseases such as ankara, boar, etc. from ancient times. Especially in the modern era, it has been used as a raw material for fertilizer since it promotes the growth of living things with ceramic material that emits much far-infrared rays known to be beneficial to human body. Especially, since the elvan stone is a porous rock, It absorbs and decomposes contaminants and bacteria in the water, and acts to prevent odor removal and decay. In addition, it absorbs and removes heavy metals such as mercury and cadmium, neutralizes cement toxicity, and acts as an antibacterial, insecticide and deodorizing agent. In particular, even strong acid or strong alkaline water will turn into weak alkalinity (pH 7.2 ~ 7.4) and turn into water suitable for human body.

ChunGiTo is a complex alkaline mineral mineral that is non-toxic and has been used as a precious stone for skin diseases and traumatic treatments. It contains more than 45 kinds of minerals. It has excellent effect of improving water quality and has a high efficiency of more than 93% Tourmaline has the only permanent electrical properties among the minerals present on the earth. Tourmaline emits anions, weak currents and far-infrared rays, and is used as an energy source to stimulate biological growth and supply vitality. They promote cell activation, cardiac strengthening, growth and development, skin shine, and good effects on the kidneys, liver, pancreas and the like.

Zeolite (Zeolite) is an inorganic substance which causes ion exchange reaction. It is a mineral with remarkable ion exchange ability and belongs to a mineralogical zeolite group. The zeolite has excellent deodorizing power and antibacterial power along with the far-infrared radiation, which purifies the water quality. Such zeolites can use natural gemstones, but artificially synthesized zeolites can be used. The main components of the zeolite are, for example, 65.4 wt% of SiO2, 13.2 wt% of Al2O3, 1.62 wt% of Fe2O3, 3.57 wt% of CaO, 0.92 wt% of MgO, 1.77 wt% of K2O and 2.03 wt% of Na2O.

The zeolite is a fine porous formed by the action of the volcanic ash of the third layer and is excellent in adsorption power and chemical cation exchange function. It is used for removing and purifying automobile noxious gas components, various heavy metal harm removers, gas adsorption deodorizers, water softeners and agricultural land improvement agents It is a mineral that is used as a catalyst for environmental purification. These zeolites adsorb and purify various contaminants when they penetrate into water.

Germanium is an off-white mineral, composed of 32 electrons. When a foreign object touches it, one of the four outermost electrons protrudes out and combines with the electrons of the foreign substance, pulling the foreign substance into the vacant space, give. At this time, pure oxygen is generated to neutralize, neutralize and neutralize contaminants that are acidified by neutralizing, neutralizing, or eliminating the action, converting it into an alkali substance, and combining it with heavy metals to produce other toxic substances.

Silicate (SiO ₃ ) is pollution-free detergent mainly made of silica which has self-cleaning capability to decompose water organic matter, and it can remove the laundry poison by using laundry which is made of silicate as a main component, and moss It is said that the silicate has a self-cleaning ability (far-infrared ray) that cleans the water with strong alkalinity.

The physical properties of raw ore are silicate minerals, which generally have a high ion exchange capacity and have a plate-like structure. Due to the nature of this structure, H2O enters and exits the inside of the particles. Therefore, the surface area per unit mass including both the outer surface and the inner surface is very large, so that the surface area per 1 g reaches 500 to 1,000. Their surfaces have (-) or (+) charges and cause a variety of phenomena, such as attracting ions with the opposite sign. The chemical characteristics of raw ore have ion substitution, adsorption, reactivity with chemicals, formation ability of organic and inorganic complex, catalytic ability, swelling property, viscosity, plasticity and so on which are called chemical affinity, It may also exhibit the colloidal properties of suspended particles.

Among these various properties, it is very easy to utilize as a redox remover for raw ore because it is based on ionexchange capacity and cation exchange between interstitial layers reacts with organic minerals.

In addition, charcoal and white carbon are used in the rust and red tide removing agent of the present invention. The above-mentioned charcoal and white carbon are used as powders in the form of micronized powder having a particle size of 600 to 700 meshes like mineral powder. Particularly, since there are innumerable pores in the charcoal, hydrogen peroxide can be permeated into these pores, and hydrogen peroxide is gradually released to the outside, which has the advantage of continuously decomposing organic matters, and is particularly effective in removing rust and red tide .
