froth flotation systems

Dissolved air flotation » Ecologix Systems

A very similar process known as Induced Gas Flotation (IGF) and Dissolved Gas Flotation (DGF) are also used for wastewater treatment in the oil industry where atmospheric air is substituted with Nitrogen gas to reduce the risk of explosion. Froth flotation is commonly used in the processing of mineral ores.

Dissolved air flotation - Wikipedia

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.
