Health benefits of drinking water filter can help you care for the whole family healthy drinking water purifier machine function is to filter the water floating, heavy metals, bacteria, viruses, and so to get rid of it with high filtration technology, generally for five stage filtration, filter, also known as a sleeping mat PP cotton, the second stage granular activated carbon, and the third stage is a precision compressed activated carbon, reverse osmosis membrane or sleeping mat * ultrafiltration membranes, activated carbon after five sleeping mat. Water purifier water pollution not only more serious areas of application, but also can filter into conventional chlorine in tap water, and can improve the taste of water. 4 standard Chinese water purifier forthcoming national industry standards, including "household and similar electrical appliances - Safety - Particular requirements for UV radiation water treatment appliances," "the special requirements of household and similar electrical appliances - Safety cold water dispenser", "home and similar water purifier ultraviolet disinfection, "" household and similar use reverse osmosis water machine, water purifier nanofiltration pressure tank "four national water purifier home water purifier / water purifier industry standard drafting session held in Kunming, Yunnan Province in May 2013, 17-19. This four criteria, the former two are water purifiers national standards, mandatory safety standards; after two is the industry standard, is recommended product standards. 5 Market Analysis With constantly increasing pollution, drinking water, health and more difficult, so as a drinking water purifier human health supplies was well favored, leading water purifier market, more and more brands more miscellaneous . Up to now reports around the water, such as the financial media, "New Century Weekly" magazine recently to "tap truth" revealed the cover story for the national water quality standard situation: only 50% of the water passing tap water has been the focus of media attention, With the tap of the original plans to implement the new standards to be postponed to 2015, water is related to people's normal life. Indeed, with the rapid development of modern industry, water pollution is rapidly increasing, the interference of various factors in the water during transport Plus, now drinking more worrying. Household water purifiers to better address these issues. The first stage works: Microfiltration: microfiltration membrane to remove the water in a variety of visible / dust and impurities. These particulate matter from aging pipes, rust, roof water tanks secondary pollution and so on. Second level: compression carbon: compressed carbon removes chlorine and organic contaminants, such as harmful pesticides. Can absorb water, organic produce odor, color and odor of these substances from water disinfection by-products. Water purifier working principle diagram III: Ultrafiltration: ultrafiltration membrane capable of removing bacteria, viruses and spores and other substances in the water. Section *: filter life indicator: The internal device designed gear structure, with the water flow through the gears rotate on an axis so that the internal movement until the outlet blocked, the water can not pass, that is, through good design travel to calculate the total amount of water over the water purifier, in order to ensure the water is safe. Most water purifier is the use of the principle of progressive resistance sieve structure of forms, from end to end multi-stage filter concatenation, filter precision in order of priority from low to high, in order to achieve a multi-stage filter dirt trapped sharing, reducing filter blockage and artificial drainage, as well as to extend the number of washable filter replacement cycle. There is also a new design idea is to apply the principle of sub-quality flow of self-cleaning mode structure, its design idea is no longer to provide as much space for hiding dirt pollutant, but take a sub-quality principle, a small isolated part of the clean water, while the water as usual as far as possible so that the flow of raw sewage flow together so promptly taken away with the water quality, to water does not rot. This will not only get purified water, they will not or can not easily precipitate dirt in the machine, to avoid the formation of secondary pollution and greatly reduce the filter loss, better water quality and more secure and energy-efficient low-carbon. This new principle of self-cleaning water filter to get the Seventh International Invention Exhibition Award, for a structure into two, it improves the traditional water purifier because a structure into a raw water * end lead to the impurity concentration in the machine piled higher in the final to become the sewage, and therefore self-cleaning water filter has no concept of sewage and sewage water purifier Instead wash water. With the improvement of living standards, water purifier will become an increasingly widespread popularity of new technology products are better meet people's needs.
