Deep ocean water is seawater that is more than 200 meters deep without sunlight reaching from the continental shelf to deep seas.

This deep ocean water is often referred to as deep water.

The present invention relates to a system for the processing of deep seawater treatment water, and there are nine types of treated water processed by the present invention, namely water supply (water industry, agricultural water), water supply (clean water), water supply, respectively. Raw water, concentrated water, demineralized water, deboron water, brine, mineral demineralized water and mineral concentrated water.

The definition of each enemy is as follows.

The water supply source refers to the sand filtration treatment by taking deep ocean water.

In addition, since the source water (fish industry, agricultural water) has abundant resources in deep ocean water itself, it is used for fisheries and agriculture without any filtration process. As a result, the source water (fisheries and agricultural water) is deep ocean water itself and purely deep ocean water without any treatment.

In addition, deboron water is processed by removing the boron in the deep sea water so that the boron concentration does not exceed 1mg / L.

In addition, the source water (clean water) refers to the processing to remove turbidity in the deep sea water so that the turbidity does not exceed 0.05 NTU.

In addition, the desalination water is made by desalination of raw water and processed to meet the water quality standards of deep seawater for drinking according to Article 33 (1) of the Act on the Development and Management of Deep Sea Water.

In addition, concentrated water refers to processed raw water to have a salt concentration of 50 per mille or more.

do.

In addition, mineral concentrated water is a treated water that is produced by filtering the deep osmosis of the deep sea water and the electrodialysis process, is a step for the development of deep sea water containing dozens of trace elements.

In addition, mineral demineralized water refers to a processed to meet the water quality standards of deep sea water by reducing sodium chloride content or by adding mineral concentrated water to demineralized water.

In addition, water-containing means that the treated water which concentrated sodium chloride satisfies Article 2 (3) of the "Salt control method". ("Function" means sap that contains more than 50/100 of sodium chloride in its solid content and has a specific gravity of 15 degrees Celsius to 5 degrees or more.)

The characteristics of deep ocean water can be reduced to five things. First, the annual water temperature is low due to low temperature stability.
