OK this looks like a great reactor. However there is a problem with the concept of stage 5, de-gassing the effluent to remove CO2.
If you de-gas the effluent before it leaves the reactor, the pH rises, the Calcium and Carbonate ions become less soluble and would be expected to precipitate out during stage 5.
Doesn't it more sense to do a de-gassing after the effluent has mixed back in with tank water?
