With the development of economy and the improvement of material life, people is higher and higher requirement for the quality of drinking water. At the same time, economic development and industrial hurricane-type, make more and more serious water pollution, water contamination of water supplies first. Water purifier products currently on the market at the core of the membrane filter is divided into two kinds of ultrafiltration and nanofiltration membrane.
Nanofiltration membrane in the separation of application showed remarkable feature of the following:
First, the intercept molecular weight between ultrafiltration and reverse osmosis membranes, is 150-2000 - g/mol.
Second, the nanofiltration membrane has certain intercept rate of inorganic salt, because it is the surface of the separation layer is made up of polyelectrolyte, with ion electrostatic interactions.
Three, ultra low pressure large flux, that is, under the low pressure (0.1 Mpa) can still work, and have bigger flux. Nanofiltration membrane separation process without any chemical reaction, no heat, no phase transition, won't destroy biological activity, will not change the flavor, aroma, and therefore is widely used in the preparation of drinking water and food, medicine, biological engineering, separation and enrichment of pollution treatment and other industries in various purification process.
Nanofiltration is currently one of the mainstream way of filtering, because of its filtering accuracy is named nanoscale (0.001 microns), part of the filtering technology has been able to virus, heavy metals, organic pollutants, scale relatively thoroughly filtered out. But for fluoride and other nanoscale particles diameter less than will not be able to effectively filter.
Now is the most widely used in RO reverse osmosis membrane, the pore size is small to nanoscale (1 nm = 10 to 9 meters), is one over one million of a human hair, naked eye cannot see, bacteria, viruses, is it 5000 times. Under certain pressure, only water molecules can squeeze through the membrane. And source the inorganic salt in the water, heavy metal ions, organic matter, colloid, bacteria, viruses, impurities through the RO membrane, so as to filter out the real straight drinking water, without any impurities. RO machine water production relative to the bottled water or bottled water more health and safety, can directly drink drink can bring to a boil.
Odie water purification products in appearance, structure, filter and so on new upgrades, and intelligent science and technology, material, machine configuration to achieve first-class level, for each user to provide the best quality drinking water, the most convenient operating experience.
