Some bacteria in natural water exceed the standard and must be filtered and sterilized.
Some water sources are meltwater from snow-capped mountains, and bacteria meet the standards. Because the snow is below zero, there are few bacteria.
Some water sources are deep lake water, so filtration and sterilization are also needed.
Some water sources are deep groundwater, which is rich in minerals.
Some water sources are river water, which is seriously polluted and cannot be used as drinking water.
Mineral water is rich in minerals, while pure water is filtered a lot.
Extended data
Mineral water is unpolluted underground mineral water that gushes naturally from deep underground or is exposed artificially. Contains a certain amount of mineral salts, trace elements or carbon dioxide gas; In general, its chemical composition, flow rate, water temperature and other dynamics are relatively stable within the natural fluctuation range. Mineral water is formed in deep circulation, containing minerals and limited indicators stipulated by national standards.
Mineral water is water containing dissolved minerals or more gases. The nine boundary indicators specified in national standards include lithium, strontium, zinc, selenium, bromide, iodide, metasilicic acid, free carbon dioxide and dissolved total solids. One or more kinds of mineral water must meet the requirements of boundary indicators.
The required contents are (in mg/L): lithium, strontium, zinc, iodine ≥0.2, selenium ≥0.0 1, bromine ≥ 1.0, metasilicic acid ≥25, free carbon dioxide ≥250, and total dissolved solids ≥ 1000. Most mineral water in the market belongs to strontium (Sr) type and metasilicate type, but there are also mineral water with other mineral components.
With the development of China's economy and society and the improvement of people's living standards, people's brand awareness of consumption is getting stronger and stronger. The emphasis on brand reflects the change of consumers' life concept. With the continuous improvement of production equipment and technical level and the homogenization of mineral water products, the physical properties of products are not much different, and only brands with profound connotations can give consumers spiritual sustenance.
For mineral water with the same quality and price, consumers prefer brand products. When the commodity economy develops to a certain stage, the competition among enterprises no longer stays on price reduction and promotion, but on brand level. Establish a famous brand and you will have the initiative to occupy the market. In the future, mineral water enterprises will compete, and enterprises with no brand or weak brand will become the OEM factories of strong brands and lose their own terminal market and competitive foundation.
