Recently, the pH of the wastewater has suddenly increased significantly, causing the alkalinity in the anaerobic tower to rise from 3700 to 6000. I would like to ask the experts what emergency measures should be taken; currently, acetic acid is being added to adjust the pH.

On our end, the acidity is increasing, and the pH value is gradually dropping. . The addition of caustic soda caused a 10% death rate of the bacteria. . .

What is the residence time? Shouldn’t this problem be solved in the wastewater pretreatment section?
