· A modified flotation cell (MFC), was used as a reactor because this device is widely used for application where three phases (solid-liquid-gas) must interact. Hydrodynamic parameters such as stirring rate, bubbles production and ozone dispersion were evaluated as well as the catalyst load, ozone mass flow, and catalyst reuse.
