The pH value of the water used for stripping in electrodialysis remains around 8, but the pH value of the water produced by electrodialysis suddenly dropped to 4.3 and remained at that level for six or seven days. What could be the reason for this?

The content of substances such as hydrogen sulfide in crude oil has increased. Take a look at the changes in crude oil.

First, analyze the current distilled water and crude oil samples; in cases of sudden changes like this, the instruments need to be calibrated first

Check for any changes in the operations. Crude oil properties, electric field strength, water injection volume, and so on
