A rectangular channel air lift bioreactor

which has good properties of mass transfer and hydrodynamics

better operation sensitivity than traditional ALR

was studied. The parameters of KLa and εg of mass transfer and hydro dynamics were experimentally studied by using CMC aqueous solutions of different concentrations. The research showed that when the rheological properties of pseudoplastic non-Newtonian fluid could be described by τs=ηγn thus By using the above correlation

the performance of the bioreactor was discussed with regard to the structure of reactor

fluid properties

and operation condition.non-Newtonian fluid
