Abstract
The invention relates to a method for maintaining a continuous mixing extending throughout the transversal section of the reactor space in a liquid containing solids and gas, and for simultaneously separating gas or gas and solids from the liquid. The invention also relates to an apparatus whereby the mixing is maintained, and simultaneously at least one phase is removed from the liquid under agitation. In a particularly advantageous fashion the method and apparatus of the present invention are suited for the stirring of bioreactors, as well as to removing gas and solids from the said reactors.
