Abstract
Apparatus for generating finely divided particulate bubbles in a liquid comprising a hollow rotor TD mounted at the end of a hollow shaft 1 in a static housing 8, 9. Liquid is drawn up through a hole 9a in the bottom of the housing and ejected from its periphery by the action of radial vanes 6 on the underside of the rotor. Gas is drawn into the rotor interior through the hollow shaft and discharged at the periphery 5a and is entrained in the liquid in the form of bubbles. The rotor has a radially tapering interior. <IMAGE>
