Induced Air/Gas Flotation Separator

The eductor type clarifies wastewater (or other waters) by removing suspended matter such as oil or solids. This is accomplished by injecting gas bubbles into the water or wastewater in a flotation tank or basin. The small bubbles attach to the suspended matter, causing it to float to the surface, where it can then be removed by a skimming device. This method is widely used for treating industrial wastewater effluent from oil refineries, petrochemical and chemical plants, natural gas processing plants and similar industrial facilities.


The mechanical type uses a motor-driven rotor (impeller) to draw air or gas from the vapor phase at the top of the vessel directly into the water phase. The impeller’s diameter and speed influence oil removal performance, as they affect the liquid circulation rate, gas induction rate and required power. The air/gas transfer rate is at least 70% higher than that of hydraulic-type units.

Process

In IAF/IGF separators, 2 to 4 cells are installed in series, allowing wastewater to pass through them sequentially. Each cell is equipped with its own motor that rotates the air bubble creation device at the bottom. The oil particles and sludge, floated by air bubbles, are discharged by the skimmer installed on the side.

  • Air or Gas is dispersed into small bubbles

  • Bubbles are attached to Oil or Suspended Solid particles

  • Bubbles float to the surface of the liquid

  • Floating oil and suspended solids are removed by the skimmer
