The hunan daily newspaper's all over the press
Water is a vital resource for human survival and safe drinking water is a basic safeguard for human health. On 16 may, the launch of the 2023 hunan water sanitation awareness week was held in changsha on the theme “concerning drinking water sanitation and sharing healthy lives”。
In response to a number of questions about drinking water, which are of great concern to you, journalists have been able to find answers through information panels at the site of the event, as well as information brochures。
Why would the tap water be milky
When piped water is transported in high-pressure closed pipes, the air in the pipes is dissolved in water for reasons such as high pressure. When running water comes out of the tap, the air in the water is released as a result of returning to normal pressure, thus forming countless tiny bubbles, making the water look white and placing it for a moment, clarifying that it does not affect drinking。
Is it possible to drink water that is now available in the district
Water is now being sold in small areas as an on-site water from water quality processors using treatments such as reverse osmosis and as a means of providing water to meet the different needs of the public for drinking water. However, current water is available for drinking as soon as possible and is not suitable for long storage. This is due to the fact that, in the first place, current-sale water machines are not properly maintained and that out-sale water may be contaminated; and, in the second place, water treated by current-soldiers is not suitable for long-term storage, especially in the light of the sun, where micro-organisms such as algae can easily breed. It is therefore recommended that residents drink better after boiled water from the current sale。
How should water purification be used every day
Water should be released for 1-2 minutes each day when the first water purification unit is opened, and the remaining water in the water purification unit should be discharged before being used. When the water-purificationer's water is of an exotic or sedimentary nature, the plant is contacted for repairs。
It is also important that water purification units are regularly maintained in accordance with the manufacturer's instructions. The current market has a wide variety of water purification units, with different water treatment materials used for different types of water purification having different useful lives. For example, polypropylene filtration cores (pp cotton) typically have a useful life of about three months, active carbon filtration cores have a useful life of about six months and intermediate fibre ultrafiltration and anti-permeable film components have a useful life of about one year. In addition, water quality and water usage can have an impact on the lifetime of water purification units, such as the relatively high use of water purification units and the relatively short replacement cycles of water treatment materials。
How about a long, massive drinking of “purified water”
The “purified water”, which is now common in the market, consists mainly of water that has been treated, such as a repermeable film, and is bottled or in a barrel. After treatment, such as anti-permeability membranes, water may be removed from some of the human essential mineral elements contained in water while effectively removing the water hardness. Studies have shown that water contains a certain amount of calcium, magnesium, etc., which can contribute positively to the prevention of cardiovascular diseases, etc. Therefore, it is not recommended that “purified water” be used in large quantities for long periods of time。
Moreover, drinking water with health functions such as “ion water” “small molecular water” “magnetic water” lacks sufficient scientific data to advise consumers not to be fooled by these so-called “functional water”。
