The parabolic disc turbine impeller is a radial-flow impeller. Its blade surface is concave, providing very strong radial discharge and dispersion force. It enables thorough gas-liquid emulsification and mass transfer. Compared with the six-blade flat-blade disc turbine impeller, its dispersion capacity and mass transfer capacity are increased by 15% and 20%, respectively. It is especially suitable for oxygen dissolution operations in fermentation-like processes, and can also be used for gas absorption, mixing, dispersion, and mass transfer operations.
