Purified water equipment system conductivity exceeds the reason?

1. Water quality problems: test the raw water quality whether there is a big change;

Solution: if the water conductivity is abnormally high because of the water conductivity rise, you can adjust the water conductivity, in the water conductivity back to normal after the water conductivity will return to the water conductivity.

2. Conductivity meter: check whether the conductivity meter is working properly;

Solution: if the meter display value is not correct, then replace the new conductivity meter.

3. Membrane module problem: check whether the reverse osmosis membrane module aging or oxidizing media detailed,

Solution: if this is the reason for the desalination rate decline is to replace the reverse osmosis membrane module;

4. Reverse osmosis membrane fouling: reverse osmosis membrane fouling caused by pollution.

Solution: reverse osmosis membrane cleaning, it is recommended that regular chemical cleaning according to the operating instructions.

5. Operational problems: whether there is a momentary shutdown or improper operation.

Solution: this situation is likely to cause reverse osmosis membrane back pressure, reverse osmosis membrane rupture, resulting in a steep rise in conductivity of produced water after restart. Replacement of reverse osmosis membrane

6. sealing ring problem: sealing ring head rupture, reverse osmosis membrane components connected to the leakage of seals caused by a sharp rise in conductivity.

Solution: It is recommended to replace the seal. Specific method is to test the water quality of each membrane module to find out the leaking part of the replacement.

7. dosing problem: equipment in the boot of the second conductivity rise is difficult to drop or drop too long, this situation is generally common in two-stage reverse osmosis, in the first and second stage in the middle of the general addition of sodium hydroxide to regulate the amount of carbon dioxide in the water to remove the measures, the amount of sodium hydroxide and conductivity have a relationship with the amount of addition, it is recommended to adjust the amount of addition.
