“…To evaluate the behavior of the waste biosorbent obtained from Pinus pinaster biomass waste in an upgrade adsorption system, a discontinuous experimental assay was performed using a preupscale air-lift reactor. The air-lift system has several advantages, such as stable fluid motion due to separation of upward and downward flows and a high efficiency of suspending particles due to the fast fluid flow [21]. To the best of the authors' knowledge, this is the first study in this kind of reactor using pine bark for the adsorption of FLX, CRB and ATZ.…”

“…Industrial applications of these bioreactors are in hydrogenation, oxidation, epoxidation, fermentation, production of single cell protein, cultivation of microorganisms and wastewater treatment in chemical and biochemical processes [1][2][3][4][5][6]. Airlift bioreactors have attracted considerable attention due to their simple mechanical design with no moving part, high capacity, good mixing, low cost, low shear stress and low power input [7][8][9].…”

The effect of mode of sparging gas on the mixing parameters of an internal loop airlift bioreactor was investigated. Two bioreactors of identical volume of 14×10 3 cm 3 and the optimum riser to downcomer cross sectional area ratio of 0.6 were studied. In one bioreactor a gas sparger was located in the draft tube and in the annulus in another. Liquid mixing characteristics, i.e., mixing time and circulation time, were employed to describe the performance of the bioreactors. The tracer injection method was used to determine the mixing parameters. A mathematical modeling based on the tanks-in-series model was employed to characterize the hydrodynamics behavior of the bioreactors. Matlab 7.1 software was used to solve the model equations in the Laplace domain and determine the model parameter, the number of stages. A comparison between the simulation results and experimental data showed that the applied model can accurately describe the behavior of the bioreactors. The results showed that when the gas sparger was located in the draft tube, the liquid mixing time, circulation time, and the number of stage were less than while the gas sparger was located in annulus. This is due to more wall effects, more energy losses and pressure drop in the case of gas injection in the annulus.
