Bubble Columns and Air-Lift Bioreactors - Animal Cell Culture

Air-lift reactors usually provide better mixing than bubble columns, the operation range is much broader. Hydrodynamic behaviour of these reactors depend to some extend on the geometry as well as on gas flow rate, gas hold up and circulation velocity, with the gas flow rate as the only independently controllable variable.
