Solving the problem of blackening during electrodialysis water separation
Thread Content
The electrodialysis tank has been in operation for nearly 3 years since its last maintenance; recently, the water discharged from it was black in color but free of oil. Please help find out the cause
There are high levels of sulfides in the water. It can be tested.
An analysis of the raw material shows that there are likely many impurities!
The oil quality is terrible! No solution; crude oil should no longer be blended with contaminated oil
What was said upstairs about the rice is wrong; recycled dirty oil cannot be mixed in, otherwise nothing can be adjusted to get things back to normal
What is the impact of sulfur in water when it is used for electrodialytic desalination?
What kind of water is used for electrodesalination? Have there been any changes in the properties of the crude oil compared to before?
It’s possible that coal tar has been mixed back into the crude oil
Mainly, the oil quality changes, and the raw materials contain many impurities
Is there any kind of sewage oil remover? It would be better to add an oil remover after electrodesalination
