Operation

Separation by induced air or gas flotation  is a process used in many oily water treatment. The bubbles of air or gas are introduced violently into water via turbines cyclones. Oil surrounds the air bubbles and goes up on the surface in the form of scums where it is recovered by self-adjustable skimmer.

Characteristics

The flotator equip many  unit treatment in oil industry. They are used in secondary treatment after a decantor. The treatment of the effluent through the flottator allows high performances : up to 98%.

The flow rate is 3 to 1000 m³/h for a residence time of about 12 minutes. The flotators are available according to standard models or measure.
