Description

Eco-friendly active natural mineral water quality improvement composition and its manufacturing method

The present invention is a water quality improving agent and a manufacturing method for improving the water quality, which is sprayed on reservoirs, rivers and natural appeals and contaminated with green algae, red tide and various pollutants, and the manufacturing method of the present invention, Natural minerals such as lite (clinoptilolite), coarse minerals, clay minerals, volcanic ash and dolomite are mixed to improve the water quality including turbidity by agglomerating, sedimenting and degrading soils.

The present invention based on natural minerals can improve the water quality by simply spraying without extinguishing the impact on aquatic organisms without a large-scale treatment facility.

The causes of contamination of reservoirs, rivers and natural appeals include the inflow of pollutants from various point sources and nonpoint sources, the occurrence of green algae and freshwater tides due to water temperature rise and eutrophication, and the inflow of contaminants due to flooding and construction work.

As countermeasures for each type of water pollution, various kinds of sewage and wastewater treatment facilities are represented for point sources and nonpoint sources, which are represented by discharged wastewater from industrial facilities and initial rainfall runoff in urban streams, respectively. And spraying of a water treatment agent on the water.

Water temperature rise and eutrophication are the causes of green algae and desalination that not only degrade water quality, including turbidity of reservoirs, rivers, and natural lakes, but also damage the habitats of water-modifying pipes and aquatic organisms. Since it can be referred to as an organic substance or nutrient salts excessively introduced from point sources and nonpoint sources, their wastewater treatment facilities can also play a role of suppressing the occurrence of green algae and freshwater tides.

Sewage treatment facilities that purify contaminated water by applying various biological, chemical, and physical treatment techniques can treat nutrients as well as high concentrations of organic matter, but it treats only wastewater discharged from specific pollutants within a given treatment capacity. As a facility, it is impossible to apply the same treatment technique to a general river or an appeal.

Therefore, as a direct treatment method for rivers or appeals, a method of maximizing the self-cleaning action such as meandering rivers or creating artificial wetlands is applied. There is a problem that takes a long time to obtain a significant effect.
