RO (Reverse Osmosis) reverse osmosis technology is a membrane separation filtration technology using pressure difference as a power, originating from the United States in the 1960s aeronautical science and technology research, after gradually converted to civil use, now has been widely used in scientific research, medicine, food, drinks, sea water desalination and other fields. RO (Reverse Osmosis) reverse osmosis technology is a membrane separation filtration technology using pressure difference as a power, originating from the United States in the 1960s aeronautical science and technology research, after gradually converted to

RO reverse osmosis membrane aperture is small to nanoscale (1nm = 10)^{-9 (1/1 milyaar m)}m), tɛ̈n tɛ̈n tɛ̈n tɛ̈n tɛ̈n tɛ̈n tɛ̈n tɛ̈n tɛ̈n, H2O molecules can pass through the RO membrane, and raw water inorganic salt, heavy metal ions, organic matter, colloids, bacteria, viruses and other impurities can't pass through the RO membrane, so making a strict distinction between the pure water and the concentrated water that can't pass through. H2O molecules can pass through the RO membrane, and raw water inorganic salt, heavy metal ions, organic matter, colloids, bacteria, viruses and other impurities can't pass through the RO membrane
