Calculate CO2 consumption to neutralize water pH
Calculate CO2 consumption to neutralize water pH
(OP)
Hi,
I need help on how to calculate the CO2 consumption to be able to neutralize the pH of water to 7 from its current pH of 11.2.
The CO2 is to be bubbled into a 2m pipe with 1-in. diameter, the water is pumped into the pipe at a rate of 3gpm.
The aim is to have the water be in a neutral pH by the time it leaves the 2m pipe.
There is a 55lb compressed tank that will supply the CO2 to the pipe, how long till I need to change tank?
Thanks :)

RE: Calculate CO2 consumption to neutralize water pH
CO2(aq) + CO3 + H2O ↔ 2HCO3
To calculate the amount of carbon dioxide, you need a water analysis showing the amount of alkalinity that is present.

The residence time that you have allowed is probably not adequate. First, you have to dissolve the carbon dioxide into solution. If not, it will be wasted into the atmosphere.

A titration will tell you. A water chemistry analysis will allow someone to estimate it for you, but a titration is cheaper and more accurate.
