What is the reason for the high conductivity of reverse osmosis pure water equipment? How to deal with it?

For the problem of conductivity of reverse osmosis pure water equipment , many of the problems encountered by the manufacturers of purified water equipment are used. In this case, the home of the water treatment network summarizes the causes and solutions of the common 7-high conductivity exceeding the standard, so that you It can solve such problems quickly and easily.

1. Water quality problem: Check whether the raw water quality has a large change;

Solution: If the conductivity of the produced water is increased due to the abnormal increase of the conductivity of the influent water, the conductivity of the influent water can be adjusted, and the conductivity of the produced water will return to normal after the conductivity of the influent water returns.

2. Conductivity meter: check whether the conductivity meter works normally;

Solution: If the meter displays incorrect values, replace the new conductivity meter.

3. Membrane component problem: Check whether the reverse osmosis membrane module is aged or detailed by oxidizing medium.

Solution: If the salt rejection rate is reduced for this reason, replace the reverse osmosis membrane module;

4. Reverse osmosis membrane fouling: The reverse osmosis membrane is contaminated by pollution.

Solution: Wash the reverse osmosis membrane. It is recommended to carry out regular chemical cleaning according to the operating instructions.

5. Operational problems: Whether there is an instantaneous shutdown or improper operation.

Solution: This situation is likely to cause back pressure of the reverse osmosis membrane, and the reverse osmosis membrane is broken, resulting in a sharp rise in the conductivity of the produced water after restarting, and replacement of the reverse osmosis membrane.

6. Sealing ring problem: The sealing ring head is broken, and the conductivity caused by the leakage of the reverse osmosis membrane module connecting the sealing ring rises sharply.

Solution: It is recommended to replace the seal. The specific method is to check the water quality of each membrane module and find out the partial replacement of the leak.

7. Dosing problem: When the device is turned on, it is difficult to lower the secondary conductance or the time for the drop is too long. This situation is generally common in the two-stage reverse osmosis, and there is usually a plus between the first and second levels. Sodium hydroxide is a measure to adjust the amount of carbon dioxide removed in water. The amount of sodium hydroxide added is related to the conductivity. It is recommended to adjust the amount of addition.
