Abstract: The process introduces oxygen and forms activated sludge suspension in activation basins. The reaction impulse occurring with self-priming or compressed air-operated spray nozzles or ejectors is used to move the gasification unit over the floor of the activation basin. Turbulence generation in the sludge can be aided by rotary compressor bodies. The design ensures that the ventilation units necessary for oxygen introduction can also be relied on to keep the sludge in suspension.

Abstract: Use of a jet nozzle, which consists of a liquid nozzle (1), a gas nozzle (5), and a momentum exchange tube (2), in which the mouth (7) of the gas nozzle (5) is arranged below the horizontal axis (6) of the liquid nozzle (1) and with respect to the momentum exchange tube (2) such that the gas exit face (7) is inclined at an angle of 0-60 DEG , preferably 5-20 DEG , to the common horizontal axis (6) of the liquid nozzle (1) and the momentum exchange tube (2), and the clear horizontal distance of the gas nozzle (5) from the liquid nozzle (1) is 0-8, preferably 0.5-3, diameters of the liquid nozzle (1), for the introduction of gases into liquids.
