The term may also refer to: * Flotation (archaeology), a method for recovering very small artefacts from excavated sediments * Flotation (shares), an initial public offering of stocks or shares in a company *Flotation, any material added to the

Induced gas flotation Induced gas flotation (IGF) 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 injecting gas bubbles into the water or wastewater in a flota ...
