Abstract: An apparatus for purifying waste liquids which includes (a) a mixing chamber for introducing and mixing a pressurized gasliquid phase, which substantially saturatedly dissolves a pressurized air into a waste liquid under the pressure, (b) a curved liquid chamber having a flat circular arcuate or curved spiral for separating the waste liquid into substances to be removed, such as flocs, etc., and a liquid, and (c) a scum outlet duct so disposed as to communicate with the curved liquid chamber at the upper portion of the chamber for discharging a scum of the substances to be removed floating on the surface of the liquid in the curved liquid chamber. The mixing chamber and the curved liquid chamber are separated from each other with partitions, but one of the partitions has an opening at the upper portion thereof so as to communicate the mixing chamber with the curved liquid chamber.
