What' s reverse osmosis system?
What's the working principle of the RO membrane for the reverse osmosis system?
through the membrane into the envelope and spirals inward to the central tube for collection.
Raw water pump→ mechanical filter→ activated carbon filter→ sodium-ion exchanger→ precision filter→
high pressure pump →Reverse osmosis→ Ozone sterilizer (UV).
2. Multi-medium filter--get rid of turbidity, suspended matter, organic matter, colloid, etc.
3. Active Carbon filter--Remove the color, smell, free chloride, organic matter, harmful matter, etc.
4. Softener--exchange "ions" of calcium and magnesium with the most common and easiest method.
5. Security filter--prevent large particles, bacteria, viruses into RO membrane, accuracy is 5um,
6. High pressure pump--Provide the high pressure to RO membrane.
7. RO system-- main part of the plant. The RO membrane's desalting rate can reach 99%, removing over 99% ions.
