Dissolved Air Flotation - an overview | …

Dissolved air flotation involves removing suspended particles or mixed liquids from an aqueous waste stream. The mixture to be separated is saturated with air or another gas such as nitrogen, and then air pressure is reduced above the treatment tank.

StackCell® Flotation | Eriez Flotation Division

Column-like performance in a substantially smaller footprint. These compact, stackable units offer considerable savings for new installations and are ideal for expanding capacity in an existing plant. A new high-capacity flotation technology, the StackCell, has been developed as an alternative to both conventional and column flotation machines.

ColumnCell - Outotec

This way, the quality of the air sparger system is an essential feature in columns. Outotec SonicSpargers promote intense air injection that generate the most appropriate size distribution of energetic microbubbles for collection of fines, enhancing flotation performance: SonicSparger™ Jet is based on ultrasonic injection of air or air plus ...

Dissolved air flotation - Wikipedia

Dissolved air flotation (DAF) 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 at atmospheric pressure in a flotation tank basin.

Pressure Characteristics in a Flotation Column

Yianatos et al. 19 have performed an experiment in large size industrial flotation column to measure axial pressure profile and derived a hydrodynamic model to describe the pressure and gas holdup profile in flotation column. Jiong-tian et al.16 have made their investigations on pressure drop performance of the packed flotation column.
