Systems for dissolving CO2 into a liquid can be used in various applications. One of the challenges with incorporating CO2 as a treatment strategy is the footprint needed for a basin large enough to use traditional diffuser type technology to dissolve the CO2 at a relative low efficiency. A conical shaped transfer device can be used easily be used on a piping or closed system. The system operates by pumping a side stream of water through a conical shaped gas transfer reactor, such as a Speece Cone, where gaseous CO2 is fed into the cone and broken up into an intense bubble swarm by the velocity of the inlet water. The cone shape design slows the water velocity down to where the buoyant rise velocity of the bubbles is higher than the water velocity which suspends the bubbles inside the cone, providing sufficient contact time for the CO2 to dissolve.
