Bubble column reactors have many important role in chemical, petrochemical and biochemical industries due to their relatively simple construction, favorable heat and mass transfer properties and low operating cost. In this study, bubble column reactor used as a photobioreactor. Efficiency of a bubble column depends on various design parameters and column geometry (configuration). In this study, an experimental investigation of the bubble column configuration on its hydrodynamics has been conducted with different superficial gas velocities. Hydrodynamics (gas holdup, bubble diameter and superficial velocity) of a bubble column system were studied at laboratory conditions.
