Airlift Bioreactors - an overview | ScienceDirect Topics

Airlift bioreactors are tower reactors for large-scale aerobic cultures where the mixing of the culture broth is done by the inserted gas via an airlift pump (Fig. 7.5).This pump injects compressed air at the bottom of the discharge pipe, which is immersed in the liquid. The compressed air mixes with the liquid, causing the gas–liquid mixture to be less dense than the rest of the liquid .
