Abstract
The present study investigates the application of induced air flotation technique on oil removal performance of a separator column (d = 10 cm; H = 150 cm). A preparation method to produce a very stable synthetic emulsion was developed. The stability rate constants K st were determined under different conditions, and K st for very stable emulsion was 0.000907 h −1. Several parameters affecting the performance of the separator were investigated. The experimental data were also analyzed in terms of a first-order kinetic rate model. A removal rate constant, K r, was obtained. The maximum oil removal obtained from stable emulsion contained 4% by weight sodium chloride was 78.1%, and the corresponding K r value was 9.18 h −1.
