Application of nanobubbles in floating kinetics models for efficient oil removal from produced water

The primary objective of this study was to gain insight into the kinetics mechanism involved in the removal of oil from produced water using nanobubbles. A small-scale device called Solari - N MBG 0.35, manufactured by Solari Energy Limited, was employed to generate nanobubbles. Batch experiments...
