In the apparatus shown the liquid and oxygen-containing gas enter at the bottom and the shearing zones comprise rotatable impellers 4 which force the liquid and gas outwardly through apertures 5. Baffles 6 and flow guides 8 cause the mixture to circulate radially without turbulence and treated liquid is discharged at the top of the apparatus.
