A very similar process known as induced gas flotation is also used for wastewater treatment. Froth flotation is commonly used in the processing of mineral ores. In the oil industry, dissolved gas flotation (DGF) units do not use air as the flotation medium due to the explosion risk. Nitrogen gas is used instead to create the bubbles.

To meet a flotation application for a specialty gas and make it cost effective you''d need specialized flotation chambers which vent to a combined vapor recovery and recompression system. You''d also need to have your ...

Flotation: DAF, IAF, SAF By Dave Christophersen, Vice President/Technical Manager Flotation is a method of separating solids or liquids from water by introducing fine gas bubbles. The bubbles attach to the particulate matter, and the buoyant force of the combined particle and gas bubbles is great enough to cause the particle to rise to the surface.
