Dry quenching coke oven water

In our plant, the pH of the water used for dry quenching of coke is between 8.8 and 9.2. After the boiler water has been in operation for about 10 hours, the pH suddenly drops from around 9 to 4-5. What could be the cause of this? (Due to power plant maintenance, all dry quenching water is made from demineralized water)

Is carbon dioxide dissolved in it?
