Recent complaints about water purification equipment is not "pure" significantly more. Shijiazhuang formaldehyde designated enterprises, Shijiazhuang indoor air treatment of the top ten brands of enterprises Shijiazhuang better than good better environmental protection engineering limited company found in the investigation, the market a wide variety of water purifier, function is similar, the range of selling price from one hundred to ten thousand dollars, however, is not all water purifier out of the water can be called pure water? Is not any water purifier out of the water can be directly drink?
Q: Is any water purifier out of the water can be directly drink?
A1: The purity of the water purified by the home water purifier is the same as the regular production line filling of the barrel water, you can drink directly. But the household water purifier cartridge to be cleaned regularly, the use of long time will reduce the filtration effect, but also produce odor. In order to ensure the filtering effect, the cartridge should be cleaned in about 2 months depending on the water source.
A2: If you use a reverse osmosis water purifier, the water is able to drink directly, if you use the ultra-filtration, it is best to heat and then say, because the ultra-filtration of the filtration of the bacteria can not be filtered out, reverse osmosis can be.
A 3: Not every water purifier purified water can drink, mainly depends on the purification principle used by the water purifier and the raw materials used. For example, commonly used activated carbon, imported and domestic will be different. Recently, the Ministry of Health on the imported brand inspection, a lot of imported brands of water purifiers have different problems, but I personally feel that a quality product, used than not good, always better than tap water to a lot of it.
A4: The central water purifier can filter out the water bacteria residual chlorine and other harmful substances, but can not reach the drinking water standards, the terminal water purifier can filter out viruses and other small harmful substances The filtered water can reach the direct drinking standards.
A 5: The purification capacity of the home purifier is limited, the water produced by large manufacturers are using membrane osmosis technology, particle filtration is just one of the steps. The pure water produced by large manufacturers is much cleaner than simple particle filtration, it is simply not a grade, can not be compared. It is recommended that the family water purifier water to be boiled before drinking.
Q: different water purifier filtered water can be directly consumed?
A 1: cartridge water purifier (drinkable)
This water purifier uses a cartridge structure, according to different needs, can be matched with different cartridges, the advantage is that the price is cheaper, the filtration accuracy is relatively high (containing ultra-filter). The disadvantage is that the life of the cartridge is relatively short (for example, PP cotton life in 3-5 months, activated carbon life in about half a year, ultra-filtration life 1-2 years), the water output is small, only suitable for drinking.
Answer 2: water purifier (drinkable)
This water purifier uses RO reverse osmosis technology, first appeared in the aviation industry, is to solve the problem of drinking water for the airmen and research and development, the advantages of high precision water (in addition to the water molecules, any substance can not go), the disadvantage is that the purified water is too pure, the lack of trace elements are beneficial to the human body, an average of a cup of pure water to be produce 3 cups of wastewater, and at the same time must use electricity.
Answer 3: centralized water purifier (not drinkable)
The water purifier is installed in the home's main water supply pipe, so that all the water in the home are purified, the advantage of a long life of the filter media (the shortest is also 5 years), easy to operate, and at the same time with the function of the backwash, you can prolong the life of the filter media. The disadvantage is that the purification precision is not particularly high, if used to deal with drinking water, the effect is not particularly good.
