The pH value of the graywater in the vaporization deaerator remains around 9.1, or even higher

The pH value of the graywater in the gasification deaerator remains around 9.1, or even higher; the pH value of the graywater in the graywater tank is around 8.3. How should this be adjusted to lower the pH value?
From the perspective of water quality, a high ammonia nitrogen level is likely to be responsible for the high pH value
It is recommended to add raw water for replacement and reduce the use of urea for desorption at night. .
There is only one reason why the pH of the deaerator is higher than that of the graywater tank, and that is related to the treatment of condensed liquid; ultimately, it is due to inadequate air lift efficiency
Replace the water and analyze the quality of all the water you use for replenishment, in order to identify the root cause
It should be a problem with the conversion stripping tower
Control the liquid level in the stripping tower and the gas-liquid separator following it (some units do not have a gas-liquid separator) at around 25%, thereby reducing the amount of condensate in the stripping gas and appropriately decreasing the amount of acidic gas that is vented (or recovered).
