A gas transfer system adapted to dissolve a gas or other compressible fluid in a relatively non-compressible liquid such as waste water with a minimum expenditure of energy. The system makes use of a drum divided by radial vanes into liquid chambers. Rotation of the vanes causes the chambers to rotate about the central axis of the drum whereby in the course of every operating cycle, each chamber is brought into operative relation with the respective interfaces of an inflow station, a gas transfer station and an outflow station. At the inflow station, raw liquid to be treated is fed into the chamber then in operative relationship therewith to produce a liquid batch therein. Concurrently, at the transfer station another batch of raw liquid in the chamber then in operative relation therewith is subjected to pressurized gas to effect the absorption of the gas by the liquid. At the outflow station, the treated batch of liquid in the chamber then in operative relation therewith is discharged to empty this chamber so that it can be refilled with raw liquid and the cycle repeated.
