How to determine whether the reverse osmosis membrane is contaminated?
Today, reverse osmosis equipment is widely used in all walks of life, but the membrane in the reverse osmosis equipment is often contaminated during use, so how do we know that the reverse osmosis membrane is contaminated?
The following phenomena occur when the reverse osmosis membrane is contaminated:
1. Water yield decreased significantly under standard pressure;
2. In order to ensure the same water production, the operating pressure of the entire equipment must be increased;
3. The pressure difference between inlet water and concentrated water in reverse osmosis equipment has increased a lot;
4. The weight of reverse osmosis membrane has increased significantly;
5. The desalting rate of reverse osmosis membrane changed significantly, and the desalting rate decreased significantly;
6. When the reverse osmosis membrane element is removed from the membrane shell, the water is poured into the inlet end after it is erected. If the water does not flow through the reverse osmosis membrane element normally, but overflows from the end face, it indicates that the reverse osmosis membrane is completely blocked.
These are some of the phenomena that will occur when the reverse osmosis membrane is polluted, and you can judge for yourself whether your membrane has been polluted. Reverse osmosis membrane plays an important role in sewage treatment equipment, effectively avoiding membrane pollution, which is of great significance for the normal operation of equipment.
