Neue Bioreaktoren für aerobe Prozesse

New bioreactors for aerobic processes. After a brief survey of the necessity of developing new reactor types, the bestknown reactors are classified into three types according to the method of introducing energy. All these reactors consist of few constructional units, of which only the dispersion systems will be considered. In all the dispersion units, gas dispersion in the range of interest in practice is by a turbulent mechanism. Thus the dispersion units can be compared directly with one another. It is shown that the efficiency of the dispersion units depends upon the properties of the turbulence generated thereby.
