venturi on external CO2 reactor

Re: venturi on external CO2 reactor

Tom,
In a recent post on APD you mentioned using the venturi power skimmer for CO2, can you provide details?

@silo, why do you have three lines going to the spraybar? I understand number 3 is the venturi loop, but what's the numbers 1 and 2 for? Won't they make your reactor less efficient because you're leaving no time to have the CO2 react with the water?

Tom, if I understand correctly the venturi loop is to burp out the gas buildup. So in this picture line 3 (where it should be on 1/2 of the reactor) will be connected to the outlet of the reactor. Why should it be that far away from the gas buildup "zone"? In my experience the gas buildup doesnt even come on 1/3 of the reactor from above. This way it'll loose it's function since it the venturi loop never reaches the gas buildup zone.

I also wonder what'll happen if you connect the venturi loop to the inlet of the reactor instead to the outlet. This way you can give the CO2 gas a second chance to diffuse in the reactor. Has anyone tried this before? In this case I was thinking connecting line 2 with the reactor inlet.
