Water Filter by langfang Huilu Filtratiion And Equpment

At present, the four main water filtration technologies are micro-filtration, ultra-filtration, sodium filtration and reverse osmosis
1, microfiltration (MF) : 50 microns, filtration precision in 0.1 as common various PP filters, activated carbon filter, ceramic filter and so on all belong to the category of microfiltration, for simple coarse filter, filter the impurities in the water and sediment, rust and other large particles, can't remove the water of bacteria, viruses, organic matter, heavy metal ions and other harmful substances.Generally cannot clean, for one-time filter material, need to be replaced frequently. 
1) PP cotton core: generally, it is only used for coarse filtration with low requirements, to remove sediment, rust and other large particles in water. 
2) activated carbon: particle activated carbon filter is the most widely sold device in the United States. It can eliminate the peculiar smell and chlorine in the water, but cannot effectively remove all toxic chemicals and other pollutants in the water. 
3) ceramic filter core: the minimum filtering precision can be up to 0.1 micron, which can be used for sterilization.But usually the flow is small, not easy to clean. 
2. Ultra-filtration (UF) : the filtration accuracy is 0.001-0.1 micron, which is one of the six high-tech technologies in the 21st century.It is a membrane separation technique using pressure difference, which can remove rust, sediment, suspended material, colloid, bacteria, virus, macromolecular organics and other harmful substances in water, and can retain some mineral elements beneficial to human body.Is the mineral water, spring water production process in the core components.The recovery rate of water in ultrafiltration process is over 95%.And can conveniently realize flush and backflush, not clog easily, service life is relatively long.The ultrafiltration membrane with filtration precision of 0.01 micron is widely used because of the best ratio of water yield and filtration efficiency. 
3. Sodium filtration (NF) : the filtration accuracy is between ultra-filtration and reverse osmosis, and the desalination rate is lower than that of reverse osmosis. It is also a membrane separation technology requiring electricity and pressure, and the recovery rate of water is low.Commonly used in industrial pure water manufacturing. 
4. Reverse osmosis (RO) : the filtration accuracy can reach about 0.0001 micron, which is a kind of ultra-high precision membrane separation technology developed in the early 1960s in the United States by using pressure difference.Almost all impurities (harmful and beneficial) in water can be filtered only by water molecules, and are generally used in the manufacture of pure water, industrial ultra-pure water, and medical ultra-pure water.Reverse osmosis technology needs pressurization, power, low utilization rate of water, and is not suitable for the purification of large amount of drinking water. 
2.Common water filters
The filter technology is divided into several types:
PP filter water purifier: the single-barrel water purifier with all kinds of PP filter cores is generally low in price, but the filter cores are easily blocked and need to be replaced frequently. Moreover, the filtration precision is not high, which is only used for the preliminary filtration of water. 
Activated carbon filters: eliminate odors and chlorine, but not toxic chemicals and other contaminants. 
Pure ultra-filtration water purifier: it can effectively remove sediment, rust, suspended matter, colloids, bacteria, viruses, macromolecular organics and other harmful substances in water, but cannot remove chlorine, heavy metal ions, heterochromy and peculiar smell in water. 
Reverse osmosis pure water machine: completely remove the beneficial and harmful substances in the water, the product is softened desalted water, but does not meet the standard of healthy water.Need pressure and electricity, low utilization rate of water (more waste water, less pure water), high cost of purification, low flow. 
Water softener: the calcium and magnesium ions in the water are generally replaced by regenerated sodium resin, which only plays the role of softening and reducing the hardness of the water, and can not be purified and various harmful pollutants in the water can not be removed.Water with a high degree of softening (low hardness) does not actually meet the standard of healthy water. 
Barrel-shaped water purifier: the barrel-shaped water purifier installed on the water dispenser generally USES activated carbon, ceramics, mineralization ball and other filtering materials, the filtering precision is not high, is the complete interception filtering way, cleaning inconvenient, easy to form secondary pollution sources, water is small. 
Mixed media filter: according to the functional characteristics of different filter materials, adopt the combination of multiple technologies to achieve a wide range of water quality treatment, and effectively remove all kinds of harmful substances in the water.Like ikea water purification machines, the use of ultrafiltration for core components, and in combination with high performance of KDF and activated carbon filter material, not only can effectively remove the sediment in the water, rust, suspended solids, colloid, bacteria, viruses, macromolecular organic matter, etc., can effectively remove the water most harmful to human body health of chlorine, heavy metals, and the different color, smell, filtered water is safer and healthier.
