Reasons for high conductivity of purified water equipment

1. It may be due to a longer service life

As the service life of membrane components increases, the salt transmittance increases. Generally, high conductivity refers to the fact that the entire water treatment system has not changed compared to the initial state. The reason for the high conductivity at this time is that the aging of the reverse osmosis membrane components leads to a decrease in desalination rate. The correct solution is to replace the reverse osmosis membrane of the reverse osmosis host, usually with a frequency (cycle) of 2-3 years.

2. Leakage of connectors

The conductivity of the equipment suddenly increases during normal operation, resulting in an increase in water discharge. This situation is due to a sharp increase in conductivity caused by leakage of the sealing ring connecting the reverse osmosis membrane component. It is recommended to replace the sealing ring. The specific method is to test the water quality of each membrane component and identify the leaking parts for replacement.

3. Reduced performance of membrane components

Scratches on membrane components, membrane oxidation, chemical cleaning damage, etc. After running the equipment for a period of time, the water production remains unchanged, the conductivity increases, and the drainage capacity increases. The membrane is degraded by an oxidizing medium, resulting in an increase in conductivity and the need to replace the membrane components.

4. There is a large amount of gas dissolved in water

When the equipment is turned on, it is difficult to lower the secondary conductivity or the decrease time is too long. This situation is usually common in two-stage reverse osmosis. In the middle of the first and second stages, sodium hydroxide is usually added to adjust the amount of carbon dioxide removed from the water. The amount of sodium hydroxide added is related to the conductivity, and it is recommended to adjust the amount added.

The above is the reason for the high conductivity of pure water equipment introduced by Hongjie Water, hoping to be helpful to you. Before purchasing equipment, we need to have a certain understanding of its composition, then understand its characteristics and defects, and make a comprehensive selection.
