There are two ways to obtain purified water, one is barreled and bottled purified water, and the other is household water purifier. Bottled pure water is expensive, and most of them are packed in small plastic bottles. Bottled purified water is mainly suitable for families to drink for a long time.
Barreled water is generally used in conjunction with drinking fountains. The existing water dispenser can not only boil hot water, but also freeze water, which is very convenient. However, water delivery usually requires an appointment in advance, and booking multiple barrels at a time will take up a lot of space. And for the elderly and women, changing water is really a physical activity. In addition, the water dispenser needs to be cleaned and maintained, and it must be replaced when it reaches its service life, otherwise the water inlet will easily breed bacteria.
Is pure water mineral water?
No way. Pure water means H without impurities? O, pure and clean water, does not contain impurities or bacteria, such as organic pollutants, inorganic salts, any additives and various impurities. Raw water is water that meets the hygienic standard of drinking 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.
Generally speaking, mineral water cannot be used as a long-term drinking water source. Although it is bottled mineral water, it is very safe to treat natural mineral water in strict accordance with national standards to ensure the content of nutrients and minerals, and at the same time control toxic and harmful substances in a risk-free range. However, good mineral water is scarce and expensive, so it is not economical to use it as drinking water for a long time. Moreover, long-term drinking requires the use of a large number of mineral water bottles, which will also cause a great burden on the environment.
