However, since the water is discharged through a closed space such as the water pipe to the outside, an air is not supplied to the water and thus the dissolved oxygen in the water is absolutely short .
Thus, since the water short of the dissolved oxygen is disadvantageous to the metabolism of the human body and the growth of plant, it is reluctant to use as a drinking water, 2 unlike a spring water which is commercially available. Also, in the water culture of the vegetable and plant, it is preferred to use the underground water of rich dissolved oxygen, rather than use the service water.
