Pure water:
Does it mean H without impurities? O, referred to as purified water or pure water for short, refers to pure and clean water that does not contain impurities or bacteria such as organic pollutants, inorganic salts, any additives and various impurities. It takes water that meets the sanitary standard of drinking water as raw water. It is made by electrodialysis, ion exchange, reverse osmosis, distillation and other appropriate processing methods. Sealed in a container, without any additives, colorless and transparent, and can be directly drunk. The space water and distilled water sold in the market are pure water.
The so-called pure water is the water after natural water has been treated, purified and purified through many processes. After many processes, the pure water can be directly drunk after removing harmful substances and bacteria.
Water is necessary to sustain life. Some health experts suggest at least eight cups, but there is no exact regulation. The demand for water varies from person to person, depending on the conditions of the subjects, proper physical exercise and the temperature and humidity of the environment. The sources of human daily water use include drinking water, beverages, water and water in food.
The intake of mineral nutrients in drinking water is also unclear. Generally speaking, inorganic minerals enter surface water and groundwater through rainwater runoff or crust, so water contains compounds of calcium, zinc, manganese, phosphorus, fluorine and sodium. Nutrients produced from water provide an important part of the daily water demand of some arthropods and desert animals, but only provide the necessary intake of a small number of people, so there is no scientific basis for drinking pure water for a long time. But drinking too much water can also lead to water poisoning (leading to hyponatremia).
