water pollution situation is not optimistic, more and more people are concerned about healthy drinking water. And in tap water and bottled water are no longer safe, peoples eyes quickly gathered at the home water purifier. Find out about the water purifier of people will find that in recent years, the vast majority of water purification products have adopted the fourth and fifth tier filtration. In this regard, there are users questioned, water purification and filtration stage is really necessary to adopt such a multi-stage filtration way? Or clean water for the benefit of manufacturers to come up with a gimmick? Here to answer for everyone.
Detailed pose purification: why use more water purifier four, five cartridge filter
Although the treated water in the water, but since the processing technology behind only by mixing? coagulation, filtration, disinfection, can not be removed during processing of heavy metals, but also bring problems such as excessive chlorine, which can be seen in recent years has been exposed water pollution incidents; and most of the rural areas do not even have running water supply, only their own wells, drinking potentially contaminated shallow groundwater, studies have shown that the culprit Hebei, Tianjin and other places of the giant sewage seepage pits or the surrounding areas of cancer villages. May be present in the water pollutants include sediment, detritus, rust, bacteria, viruses, heavy metals, organics, dissolved solids, etc., that is drinkable without filtration, hazardous to their health.
As we all know, is the most important filter water purifier core parts, determines the quality of the filter effect. In the early water purifier, a single cartridge filter is more common, but the poor purification or filtering effect, unable to completely remove contaminants from water; or rapid accumulation of contaminants, greatly reduced filter life. To avoid these problems, manufacturers have begun to adopt a multi-stage filter combinations on the water purifier, water purification on the one hand can enhance the effect, on the other hand it can extend filter life.
wasThrough continuous exploration, four, five filtration has been widely applied to the water purifier. Common filter categories include microfiltration membrane, ultrafiltration membrane, RO membrane and so on. Depending on the pore size of the filter, the filter corresponding to the different segments are involved in water purification. The microfiltration membrane filtration accuracy between 0.1 and 1 micron, the water may be trapped grit, silt, and clay particles, such as Giardia, hidden insect spores, algae and some bacteria and other impurities, organic macromolecules but allows microfiltration and dissolved solids (salts) and the like through, it is often used for water purification preprocessing step and a post-filtering stage.
one of the polymer membrane is an ultrafiltration membrane earliest development, filtered accuracy between 0.1-0.01 microns, fine pore size allowing only water molecules, minerals and trace elements by, but is now World smallest bacteria known volume of about 0.2 micron, bacteria, and thus much greater than the volume of the colloid bacteria, rust, suspended solids, sand, organic molecules and so can be trapped down the ultrafiltration membrane, thereby achieving the purification process. Before the ultrafiltration membrane may be applied to individual ultrafiltration unit may also be placed in water for RO membrane to extend the life of the RO membranes.
RO membrane filtration accuracy of 0.0001 micron, which means that in addition to the water molecules and ions through a portion of mineral, other impurities such as heavy metal ions will be trapped RO membrane. Thus, the RO membrane filter material has become the best pure, all desalination processes, wastewater recycling and astronauts are using this method, in the home water purifier is applied more widely.
Normally, the opportunity to reverse osmosis water purification front mounted 1-2 microfiltration membrane, such as activated carbon filter, PP cotton filter, etc., after ultrafiltration, the RO membrane filtration successively, after the final set of micro membrane filtration water, obviously, a four, five filters, the filter is an ideal manner, which can effectively remove impurities in the water, and the RO membrane and extended film life; in contrast, the ultrafiltration unit less RO membrane filter program, can produce fresh water containing minerals.
In order to achieve a better effect of water purification, water purification filter manufacturers in their respective product ruthless under a lot of hard work.
