RO:reverse osmosis membrane technology

Reverse osmosis technology referred to as RO, RO membrane filtration accuracy of 0.0001 micron, reverse osmosis technology principle is higher than the solution through the action, because other substances can not pass through the semi-permeable membrane then filter out pure water. The membrane aperture of RO is very small, so it can effectively remove organic matter, bacteria, viruses, metal ions, anions, chroma and other small molecular substances in water, that is, remove substances other than water, the removal rate is as high as 97% to 98%, is currently the most widely used in high purity water equipment a desalination technology. The diameter of the virus is 200 to 400 times the aperture of the RO membrane The diameter of metal ions and chemicals is 10 times that of the pore size of the RO membrane The diameter of the bacteria is more than 4000 times the pore size of the RO membrane The pore size of organic compounds such as pesticides and insecticides is about 10 to 400 times that of RO membrane.

Uf membrane technology

Ultrafiltration membrane technology (UF) is a new membrane separation technology. In the screening process, the pressure difference on both sides of the membrane is the driving force, and the ultrafiltration membrane is the filtering medium. There are about 6 billion 0.01 micron micropores on the wall of each 1 meter long ultrafiltration membrane, whose pore size only allows water molecules, beneficial minerals in water, and trace elements to pass through, while the smallest bacterial volume is above 0.02 micron, so bacteria and colloids, rust, suspended matter, sediment, macromolecular organic matter, etc. that are much larger than bacteria, can be intercepted by ultrafiltration membrane. Thus the purification process is realized.

Purification process flow

1
PP polypropylene spray melting filter element

Remove sediment, rust, suspended matter and other particulate impurities with a diameter greater than 5 microns from raw water.

2
granular activated carbon filter

Adsorbing odors, different colors, residual chlorine, hydrogen halide and other organic substances in water.

3
compressed activated carbon filter

Adsorb water very fine particles, colloids, suspended matter, etc.

4
compressed activated carbon filter

Filter out fine impurities, organic matter, heavy metal ions, viruses, bacteria and other harmful substances in water.

5
RO reverse osmosis membrane filter element

Further absorb the smell of water, improve the taste of pure water

Note: The fourth stage of the ultrafiltration water purifier is "UF ultrafiltration membrane filter core filter", which removes sediment, rust, suspended matter, bacteria, colloids, organic matter and so on.
