With the development of society, healthy food, air pollution, drinking water safety has become a concern of the people living in each topic. In order to ensure healthy drinking water, more and more people choose to buy a water purifier.
However, recently there are users post, said: "water purifier on the market is not safe, because it also filters out trace elements beneficial to the body at the same time to filter harmful substances, long-term drinking this water not only conducive to good health, but harmful. "
filtered water with water purification devices affect their health, is this really?
Recently, the reporter on the "drinking water purifier filter water on whether the body is good," the topic were interviewed 30 users, most users hold a positive attitude.
for the "water purifier filter drinking water is good for the body whether" the topic, the reporter interviewed 30 users, of which 90% of users believe the water purifier is useful, 10% said they oppose.
1 User "Crescent Moon" will firmly believe filter water purifier certainly be useful, or what the manufacturers do? Friends "to understand, as the" also said filtered water then boil, filter than never good, but be sure to boil, or even if the filter layer 100 in vain.
Dissenting friends, "Amoy Changzhou" is that, in fact, no need to buy these: "I have bought a house, but in fact is the psychological effect!"
According to the reporter, the current market It appears primarily on activated carbon purifier technology, ceramic filter technology and membrane technology. For the performance of products, businesses are likely to think that only good health and does not harm the body.
Recently, the reporter in Shijiazhuang, Hangzhou, Urumqi and other places to interview a lot of water purifier manufacturers responsible.
after-sales information officer of a certain brand of water purifier Li Li said the water purifier through five filters, sediment, rust and chlorine, bacteria, colloids can be filtered out, and remove the smell of water . The treated water will still contain some trace elements and minerals, suitable for drinking, easy absorbed by the body, activated human cells, health and safety.
Another brand of Xinjiang branch senior manager, said Liu Fue, water purifier on the market in both the activated carbon, there are even some high-density activated carbon. Activated carbon can adsorb carbonaceous organic pollutants, such as fertilizer, Pesticides, plastic agent, but not the absorption of inorganic elements and heavy metals, because these substances do not contain carbon.
Reporters found that, for the performance of products, businesses are likely to think that only good health and does not harm the body. So, the market water purifier in the end there is no good does it do to the body?
Tsinghua University professor Liu Wenjun told reporters environment, now more respected activated carbon technology. It can significantly improve the removal of a large number of trace organic compounds and heavy metals, security, water quality harmful, but can not remove the disease-causing microorganisms.
Professor of Environmental Tsinghua University Liu Wenjun, said on CCTV reporter, currently on the market are mainly emerging water purifier activated carbon, membrane technology and ceramic filter technology. "Membrane Technology" water purifier is further divided into "microfiltration", "ultrafiltration", "NF", "RO" four categories on the market. Wherein "microfiltration" and "ultrafiltration" can only remove larger particles, while the "nanofiltration" and "reverse osmosis" beneficial agent will filter out the water, such as sulfate, calcium and magnesium ions. Calcium and magnesium ions cardiovascular benefit, if low calcium and magnesium ions, can lead to increased incidence of cardiovascular disease. Long-term consumption harmful.
In addition to the "membrane technology," Application of ceramic filter technology in the market is relatively broad. It has anti-corrosion and oxidation effects, but limited effect of trace organics.
Liu Wenjun told reporters, is now more respected activated carbon technology. It can significantly improve the removal of a large number of trace organic compounds and heavy metals, security, water quality harmful, but can not remove the disease-causing microorganisms.
Professor of Chemical Engineering, Xinjiang University, topaz band, said all kinds of technology has its own advantages and disadvantages, people choose the best products to the activated carbon technology and comprehensive utilization of UV technology. "UV technology, physical technology, does not produce by-products, having the disinfecting effect spectrum, have a good effect on Cryptosporidium and Giardia. Therefore, these two techniques may be combined to achieve the removal of harmful trace organic compounds and heavy metals, but also retains the trace elements beneficial to human body. "
Thus, currently appearing on the market all kinds of water purifier has its own advantages and disadvantages, poor choice of words, for people It does have good health hazard. Experts suggest that high water quality requirements of consumers, try to choose the use of activated carbon technology and UV technology, water purification products.
