Mixing a liquid or suspension beneath a gas space in a closed container comprises supplying a stream of the liquid or suspension as a drive jet for a submerged ejector which aspirates gas from the gas space and discharges the gas together with the drive jet into the liquid or suspension in the container. Independent claims are also included for: (1) container comprising a liquid or suspension beneath a gas space and an ejector with a drive nozzle and a suction chamber in communication with the gas space; (2) container comprising a liquid or suspension beneath a gas space and an ejector jet nozzle having a drive nozzle surrounded by a suction chamber discharging into a mixing nozzle and an impulse exchange chamber into which the outlet of the mixing nozzle is directed, and a connection between the suction chamber and the gas space; (3) ejector jet nozzle having a drive nozzle surrounded by a suction chamber discharging into a mixing nozzle and an impulse exchange chamber into which the outlet of the mixing nozzle is directed, where the transition between the mixing nozzle and the impulse exchange chamber is provided with a jacket fitted with a dip pipe or a connector for a dip pipe; (4) mixing a liquid or suspension beneath a gas space in a closed container by supplying a stream of another liquid or suspension as a drive jet for a submerged ejector which aspirates gas from the gas space and discharges the gas together with the drive jet into the liquid or suspension in the container.
