In view of the conductivity problem of reverse osmosis purified water equipment, many manufacturers of purified water equipment often encounter problems, in view of this situation, we have summarized the causes and solutions of 7 common conductivity exceeding the standard, so that you can solve such problems quickly, simply and effectively.　　
1. Water quality problems: detect whether the quality of raw water has changed greatly;　　

Solution: If the conductivity of the inlet water is abnormally high and the conductivity of the water production increases, the conductivity of the water production can be adjusted, and the water conductivity of the water production will return to normal after the water conductivity of the water inlet water is reduced.

2. Conductivity meter: check whether the conductivity meter is working normally;　　
Solution: If the meter displays an incorrect value, replace it with a new conductivity meter.
3. Membrane module problem: check whether the reverse osmosis membrane module is aged or oxidized by the medium.　　
Solution: If the desalination rate decreases due to this reason, replace the reverse osmosis membrane module;
4. Reverse osmosis membrane fouling: Reverse osmosis membrane fouling due to pollution.　　
Solution: Clean the reverse osmosis membrane, it is recommended to carry out regular chemical cleaning according to the operating instructions.

5. Operation problems: whether there is instantaneous shutdown or improper operation.　　
Solution: This situation is easy to cause the back pressure of the reverse osmosis membrane, the rupture of the reverse osmosis membrane, and the conductivity of the water produced after re-starting. Replace the reverse osmosis membrane
6. Sealing ring problem: The sealing ring head is broken, and the conductivity of the reverse osmosis membrane module is leaked due to the leakage of the sealing ring.　　
Solution: It is recommended to replace the sealing ring. This is done by testing the water quality of each module and identifying the leaking parts to be replaced.

7. Dosing problem: the equipment is difficult to lower when the secondary conductance rises or the time is too long, this situation is generally common in two-stage reverse osmosis, in the middle of the first and second stage, there are generally sodium hydroxide measures to adjust the amount of carbon dioxide removal in water, the amount of sodium hydroxide added is related to the conductivity, it is recommended to adjust the amount of addition.
