A vessel has at one end wall an inlet for feeding waste water and at the opposite end wall an oulet for purified water. The top side of the vessel is open and the bottom has a V-shaped cross-section with an air-feeding nozzle pipe extending along and through the vertex of the bottom. An air uptake channel is mounted in the vessel at a spaced relation to the bottom portion and has an inlet facing the nozzles of the air-feeding pipe. The outlet of the uptake channel is below the level of the treated water.
