Among several separation processes, the air flotation distinguish as remarkably high potential separation process related to its high separation efficiency and throughput, energy-efficient, simple process, cost-effective, applicable to a wide range of oily wastewater and no by-products. The current study aimed to investigate the effect of the type and concentration of surfactant on the stability of oil-water emulsion and efficiency of the separation process. For this purpose, three types of surfactant where used (anionic SDS, mixed nonionic Span 85/Tween 80, and cationic CTAB). The results demonstrated that the Span 85/Tween 80 surfactant has the best stability, and it increases with the surfactant concentration augmentation. The removal efficiency with CTAB surfactant reached to approximately 95% at concentration of 0.3%, and decreased by increasing the surfactant concentration. The mean diameter of bubbles generated in emulsion with CTAB surfactant was 71 µm, which was lower than that obtained with the other two surfactants.
