This paper focuses on the effect of surfactants on the bubble size. Bubble size in SDS/water system were investigated at various superficial gas velocities (0.13, 0.26 and 0.5 cm/s). On the other hands, Bubble diameter were determined for different values of SDS surfactant concentration. Surfactant concentration in water were 0.05, 0.02 and 0.1 vol.%. Tap water and aqueous solutions with surfactants (anionic, non-ionic and zwitterionic) are used as liquid phases. The bubbles size in this phase is determined at C s =0.05%vol and u g =0.13cm/s. The bubbles are generated into a small-scale bubble column making of Plexiglas with height of 1.2m. High speed photography techniques are used to measure the bubble size. The experimental results were shown that bubble diameter in SDS/water system is larger than other systems. In solution of SDS, Sauter mean bubble diameter (Location A and D) decreases when superficial gas velocity increased.
