Water is the source of life. The safety of drinking water is related to the health of residents. Many nutrition experts recommend plain water as the healthiest drinking water. Because tap water is natural water, rich in minerals with reasonable ratio, it is most beneficial to human health. In addition, after the water is boiled, some organic pollutants, such as chlorine and its derivatives, are easy to volatilize. Therefore, after the water is boiled, the water quality and water hardness are improved, and an appropriate amount of minerals are preserved. However, the boiled tap water scale contains harmful substances, mixed with heavy metals, calcium salts, dust, germs, and corpses of insect eggs, which should be removed as much as possible.
The experimental results show that 30 liters of boiled tap water in northern Beijing is filtered by Lind membrane, and the content of arsenic and cadmium in scale is up to 10.8 μ g and 31.2 μ g respectively; The content of lead is very high, reaching 270μg. And the content of silver, nickel, manganeseare 0.7 μg, 120 μg and 40.8μg respectively. If the scale is not filtered, the amount of heavy metals entering the body through drinking water in half a month is astonishing. After filtration, not only the harmful heavy metal elements were reduced, but also the proportion of trace elements beneficial to human body did not change significantly compared with that before filtration, which was very suitable for drinking.
Therefore, the Lind membrane with certain parameters is used to remove the scale of boiled tap water, which not only improves the safety of drinking water, but also retains the beneficial trace elements and natural properties of water, and solves the problems that have plagued drinking water experts for many years.
On the basis of retaining all the advantages of traditional track etched pore membrane, the Lind membrane greatly improves the liquid filtration speed and pollution-carrying capacity of the membrane per unit area, enabling it has the ability onfiltrating a large amount of liquid under extremely low pressure. Therefore the filterstructure can be greatly simplify, which laying a technical foundation for the development of portable drinking water filter.
Lind membrane technology will bring new opportunities to the water purification industry with a brand-new way of water purification. Boiled tap water is "selectively filtered" directly according to human needs, eliminating the need for other expensive water purification equipment, which making drinking water not only cleaner, but healthier and more affordable for the public.
In order to the public can drink clean and healthy water anytime and anywhere, Lind membrane Co.Ltd. has cooperated with many domestic companies to develop various types of portable water purification cups.
