One –stage Reverse Osmosis Unit video
One –stage reverse osmosis unit adopts different processes according to different source water quality. Generally,after the tap water is treated by the first-stage reverse osmosis device. The conductivity of the produced water is <10 μS/cm. And the conductivity of the produced water after the second-stage reverse osmosis system is <3 μS/cm.
After the reverse osmosis system, the ion exchange equipment or the EDI equipment can be used. Ultrapure water was prepared to a resistivity of 18 megaohms at 25 ° C (about 0.056 μS/cm).
The core part of the single-pass reverse osmosis unit is that the reverse osmosis membrane is also the key to determine the quality of the produced water. However, the pros and cons of the reverse osmosis system (also known as the pretreatment system) is the key to determine the stable operation of the reverse osmosis system.
