What is direct drinking water? What is the standard of direct drinking water?

Direct drinking water, also known as healthy living water, refers to water that is pollution-free, non-degradable, meets human physiological needs (contains beneficial mineral elements similar to human body), and has a weakly alkaline pH value and can be directly drunk.

Direct drinking water standard:

1, does not contain any toxic, harmful or odorous substances.

2. Small molecular groups (composed of 5-6 water molecules).

3. The PH value of water must be weakly alkaline between 7.0 and 8.0.

4, the dissolved oxygen of water should reach.

5. The hardness of water is moderate, based on the content of calcium carbonate (50mg/L-200mg/L).

6. Water must contain mineral trace elements needed by human body.

7. Meet the needs of human physiological activities.
