Pure water equipment appear & other;
Arsenic & throughout;
, it is well known that inorganic arsenic is carcinogenic substance, excessive intake can lead to skin cancer, cardiovascular and respiratory system and nervous system, known as arsenic, which is one of the arsenic compounds.
While some brand blamed & other;
Transportation and storage process pollution cause & throughout;
It is a question, but in the industry.
Department of health detection technology researchers point out, & other;
Water purifiers arsenic problem may be largely on the filter head and filter material.
”
straight drinking water filter core components of pure water equipment, according to the filter structure in general can be divided into RO reverse osmosis water purifiers and water purifier ultrafiltration membrane and so on. In the survey found that the problem of water purifier filter materials although each are not identical, but have adopted these basic filter material, activated carbon, PP cotton and add the hollow fiber ultrafiltration membrane or KDF ( Pure copper zinc alloy) Compound and into.
examination organization experts and relevant industry insiders agree that in the material, could lead to excessive amounts of arsenic is activated carbon, because the raw material of activated carbon or is likely to be contaminated during the process of making craft, and contains trace amounts of arsenic. In addition, the alloy material can also be the source of arsenic ( Note: arsenic can be used in the manufacture of cemented carbide, such as copper containing trace arsenic can prevent dezincification, KDF is pure copper zinc alloy) 。
cancer & other; Black core & throughout; Used in great quantities in the water purifier
it is known that water purification idea earlier proposed by the United States, BSF of advanced technology and excellent craft are also in the United States. However, in our investigation, we found that the import in the including American brand, test results of water purifier is no accident. As the core component of water purifiers, activated carbon filter the percent of pass is generally low. Previously, the Chinese center for disease control and prevention environmental experts have pointed out, on the basis of which 2006 to 2009, the hygiene inspection data of different types of household water purifiers, according to the activated carbon filter is not qualified rate is higher, its causes include total soluble solid, fluoride, turbidity, aluminum, arsenic indicators unqualified immersion test, etc. It is these cancer & other; Black core & throughout; Used for water purifier is buried under a curse.
residual material inside the purifier can cause water & other Secondary pollution & throughout;
in the water purifier industry there is a myth, is only for the detection of water after filtration purification, but in fact, after the water through the filter, will remain a large amount of harmful substances within the purifier, which can cause water & other; Secondary pollution & throughout; 。 And at present, there is no for purifier existence & other Secondary pollution & throughout; The specialized test.
in addition to household water purifiers, now many village will also include a so-called sale water machine. One yuan per barrel, looks very cheap. But in fact is a bigger than household water purifier water purifier. The design and function with same household water purifiers, also face problems such as filter and secondary pollution.
the domestic water purifiers, correct understanding famous nutrition experts, drinking water expert professor fu-xing li pointed out that the real health of water on the basis of non-pollution standard: there are two kinds of the most fundamental one is the natural weak alkaline, the second is to make the water contains a variety of minerals and trace elements. Water purifiers in filtered water purification process, although filtering some suspended solids, but also to some of the essential minerals and trace elements in water filtered out. Moreover, the purification and filtration, will originally belong to neutral or weak alkaline water water to become acidic water, and purified water PH value.
