For the purpose of introducing or removing gases into liquids or out of liquids, in particular substrates being subject to a biological conversion, rotating plates (3) are immersed into the liquid phase. The plates (3) are rotatably arranged within a tubular receptacle (1) and arranged in at least one axial section such that they alternately include with the axis (2) of rotation extending in parallel relation to the liquid level an angle of more and less than 90.degree.. Shut-off valves (9) for the gas supply conduit and for the gas discharge conduit are connected to the tubular container (1). The plates (3) are provided with a rough surface and are preferably formed of a porous, in particular foamed, material, wire mesh, wire grating or expanded metal sheet. (FIG. 1)
Apparatus for introducing or removing gases into liquids or from liquids, in particular substrates being subject to a biological conversion, comprising a rotor rotatably supported within a horizontal tubular receptacle for rotation around a rotation axis extending in essentially parallel relation to the surface of a liquid in the receptacle, the rotor having plates non-rotatably connected with the rotor and arranged in transverse direction to said rotation axis and at axially adjacent locations, said plates being partially but not wholly immersed in the liquid in the tubular receptacle, the surface of said plates being rough, and axially adjacent plates having in at least one section comprising the rotation axis alternately an angle of more and less than 90.degree., the circumference of the plates being shaped relative to and spaced from the inner surface of the receptacle a small distance such that the space throttles liquid flow therethrough with the result that, upon rotation of the rotor about said rotation axis, the liquid level between adjacent plates is alternately lifted and lowered, the receptacle having connected thereto at least one liquid inlet, one liquid outlet, and at least one gas inlet and gas outlet.
