A safe and cost effective alternative to the use of sodium hydroxide (caustic soda) or other chemicals for wastewater alkalinity and pH adjustment.

Add or remove dissolved CO2
Note: in a treatment plant CO2 generation is a ‘given’ as BOD/COD is oxidized to CO2
=> pH will always come down spontaneously even if we dose all influent to >pH 8.5
=> system self-corrects – high pH influent can’t upset the plant unless greatly overdosed
=> excess CO2 generation is normally stripped by aeration
There is a direct correlation, but pH and alkalinity are not the same.
pH is a measure of the amount of hydrogen ions (H+, acid) in the water.
M Alkalinity is a measure of the bicarbonate (HCO3–) concentration.
Think of M Alkalinity and bicarbonate as dissolved limestone (CaCO3).
