Flotation in Water Treatment SpringerLink

Abstract. Dissolved-air flotation is a very effective solid-liquid separation process used in water treatment, as an alternative to sedimentation, to lower the solids concentrations before granular filtration. This enables filters to be operated more effectively and cost efficiently to produce a filtered water quality suitable, after ...

Gas Flotation - KASRAVAND

2022-1-9  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 flotation tank or basin. The small bubbles adhere to the suspended matter causing the suspended matter to float to the surface
