Why doesn’t the pH value change much as the acidic gas condensate enters the graywater tank?
After high flashing, under such pressure, not much acidic gas remains dissolved. The acidic gas condensate is weakly acidic, and its amount is also small.
The acidity is too weak; it isn’t sufficient to consume the calcium and magnesium ions inside. So the PH basically doesn’t change.
The acidic gas condensate is alkaline because it contains some ammonium salts dissolved in it, but mainly ammonium bicarbonate. Ammonium bicarbonate is a salt of a weak acid and a weak base; it undergoes amphoteric hydrolysis, which has little effect on the pH. Moreover, the amount added is relatively small, so there is not much change in pH.
