Shallow Air Flotation DAF Unit for Waste Water Treatment

Shallow Air Flotation Introduction
Shallow Air Flotation is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids.
The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air atmospheric pressure in a flotation tank basin.
The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.
