Water Industry Network HC : Controversial new national standard
Mineral water is deep formation circulation, and with national standards and restricted indicator minerals. Under the physical conditions and regional differences in drinking water, choose the right mineral water for drinking, can be a supplementary minerals, especially trace elements role. Summer season due to sweating the loss of drinking mineral water, mineral supplement, are effective means.
National standards specified targets, including nine boundaries lithium, strontium, zinc, selenium, bromide, iodide, metasilicate, free carbon dioxide and total dissolved solids, mineral water must meet one or more limits specification requirements, the requirements were (unit: mg / L): lithium, zinc, iodide were 0.2, Se 0.01, bromide 1.0, metasilicate 25, 250 free and total dissolved carbon dioxide Solid 1000. Most of mineral water market is strontium (Sr) type and type of metasilicate.
Use mineral water, do not select a limited indicator than the national standard requirements of the product. In the purchase, care should be cap is loose, the bottle is bright, with or without foreign bodies floating so. In addition, the spa Water meter Surface tension is large, light up a coin to the water test, coins can float in the mineral water, and can not float in the general drinking is not on.
China national standard for drinking natural mineral water: natural mineral water is a natural emission from deep underground or exposed unpolluted by artificial underground mineral water; a certain amount of mineral salts, trace elements and carbon dioxide; in general, their chemical composition, flow rate, temperature and other dynamic in the context of natural fluctuations of relative stability. "National standard" is also set limits to mineral water standard indicators, such as lithium, strontium, zinc, bromide, iodide, metasilicate, selenium, carbon dioxide and total dissolved solids free. One must have one (or more) indicators in line with the above ingredients can be called natural mineral water. "GB" also provides some of the elements and chemical compounds, radioactive materials limit indicators and indicators of hygiene to ensure the safety of drinking. According to the water quality of mineral composition, in general, within the boundary of the target, contains useful elements, for occasional drinkers will not achieve any substantial physiological or pharmacological effect. However, if the long-term consumption of mineral water, on the human body does have a more significant role in nutrition and health care. Compliance with our natural mineral content of more metasilicate, lithium, strontium, for example, these elements have with calcium, magnesium similar biological effects, can promote the growth of bones and teeth, help bone calcification, osteoporosis prevention and treatment loose; can prevent high blood pressure, protects the heart, reducing cardiovascular morbidity and mortality. Therefore, high and low content of metasilicate, is the world's most commonly used by countries to evaluate the quality of mineral water, the most important indicator of the boundaries. Lithium and bromine mineral water in the central nervous system can regulate the activities, with calm and sedation. Long-term consumption of mineral supplement in the diet can also calcium, magnesium, zinc, selenium, iodine and other nutrient deficiencies, to enhance immune function, slow aging, prevent cancer, prevent hypertension, gout and rheumatic diseases also have a good effect. In addition, the vast majority of mineral water is slightly alkaline, for the body Environment Physiological characteristics, help maintain normal osmotic pressure and acid-base balance, promote metabolism, speed recovery from fatigue. What is mineral water
Mineral water is up to the national standard for natural mineral water, spring water or mineral water can be pumped well water, mineral water without any Additive Must be purely natural. National standard GB8537-95 mineral requirements, nine compliance projects, compliance with any of them to recognize it as mineral water, mineral water more to the project and strontium metasilicate. Generally higher conductivity of mineral water, most of the 400-1000 s. A lot of mineral water, high hardness, in the 200-300mg / L more. Any high electrical conductivity and total hardness of the mineral water does not taste good. Conductivity of less than 300 s, total hardness less than 100mg / L of mineral water taste more sweet. .Are you looking full ebook about this topicGet Full Ebook For This Article
