When I was in laboratory I learned the term "degassing," which simply meant removing the gas from the liquid as much as possible. With a normal calcium reactor there is effluent, or liquid coming from the reactor that has dissolved calcium and other stuff. In the liquid there is also carbon dioxide and I know that because the desired pH of effluent is normally around 6.7.
So my question is, what are people doing to "degas" or lower the carbon dioxide level from the effluent so that it does not chronically lower the pH of the entire system. I was reading from my Pinpoint pH controller manual to use an air stone in a cup that the effluent runs into, but I was wondering if there is a cooler, better method?
