ABSTRACT:
Waste matter contained in a liquid is removed therefrom by introducing the liquid into a cell and introducing gas into the liquid to float waste matter to the liquid surface in the form of a floating scum. Gas nozzles situated adjacent the liquid surface are oriented to eject streams of pressurized gas across the liquid surface to blow scum into a waste outlet disposed adjacent the liquid surface. The nozzles are vertically adjustable to conform to different liquid surface levels.
