First: Clean water without pollution. However, it is not enough to purify drinking water. It is necessary to pay attention to the important influence of water quality and nutrient elements in the water on the human body.
Second: Maintain a certain hardness of hard water. The various ions in the water constitute the hardness of the water. Hard water contains high levels of calcium.
Third: Water containing essential mineral elements. The ions of this vital kinetic element affect or determine the pH of the water, the hardness and the size of the water cluster.
Fourth: weak alkaline water. The pH is preferably 7.00-8.00 to maintain the body's acid-base balance.
Fifth: Small molecule water. The nuclear magnetic resonance method is used to test that the half width of the water molecule group should be less than 100 Hz; if the total amplitude is wide, it means that the water molecules in the water are stringed together to become a chain structure with a large diameter, which is not easily absorbed by the human body through the cell membrane. The quantum micromagnetic wave method can also be used to test the "history of water". The water with a positive value of +20 is the best; when the value is negative to -20, the water molecule condensation structure has no media effect on the biochemical reaction of the human body. Still water.
Sixth: Living water, that is, the nutritional and physiological functions of water, has no degraded water and water with vitality. Water functions include solvency, penetration, diffusion, metabolism, emulsifying power, and detergency.
Seventh: Dissolved oxygen and carbon dioxide in water are moderate (dissolved oxygen in water is not less than 7 mg per liter).
