There are many product types and brands in the water purification market, including ultrafiltration machines, R/O reverse osmosis filtration, etc. R/O reverse osmosis is currently the safest and healthiest filtration method.R/O reverse osmosis was first used in aerospace, and is now used for civilian purposes.R/O reverse osmosis membrane production technology is only available in the U.S., Japan, and South Korea, and the domestic market is not yet capable of producing this type of membrane, and even if it is available, the membrane has not yet reached the level of R/O. The pore size of the membrane is generally one ten-thousandth of a micron. Membrane pore size is generally in one ten thousandth of a micron, general bacteria, germs volume than this large, so that only water molecules, oxygen atoms and a small number of metal ions through the side of the bottom of the removal of impurities in the water, bacteria, germs and residual chlorine role? The purely physical way of purifying tap water.
At present, most of the R / O drinking machine are used in South Korea, "the Korean" R / O membrane, the Korean R / O membrane is also widely used in the pure water industry, such as Nongfushanquan, Wahaha, China Resources Beer and so on. This is like a computer brand, but the core of the processor is either INTEL or AMD, the core of the R/O drinking machine is R/O membrane. There are only 6 major membrane manufacturers in the world. The only manufacturer that has the technology to produce both membranes and water dispensers is World Han.
It is recommended that when you buy, you ask about the filtration method and what kind of membrane is used. Domestic brands include Midea and Qinyuan. Overseas brands such as Shi Han, Fanucan, AHP and so on.
