  • Dissolved Air Flotation - Westlake Environmental ...

    GENERAL INFORMATION The Westlake Environmental Dissolved Air Flotation (DAF) system is very versatile and effective for cleaning industrial wastewater. It very efficiently removes suspended solids, oil and grease, metals as well as the suspended biological oxygen demand (BOD) and chemical oxygen demand (COD). Removal rates in excess of 95% are common. Some installations report 99.9% []

  • dissolved air flotation questionnaire

    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.

  • Dissolved Air Flotation Komline-Sanderson

    Dissolved Air Flotation (DAF) is a process for the removal of fine suspended material from an aqueous suspension. The term “flotation” indicates something floated on or at the surface of a liquid. The DAF provides the energy for effective flotation in the form of extremely fine air bubbles, which become attached to the suspended material to be removed. This attachment of bubbles to the ...

  • Dissolved Air Flotation - an overview ScienceDirect

    Dissolved air is the most common type of flotation gas used in potable water treatment. The dissolved air flotation (DAF) process mixes a clarified stream from the outlet of the unit with air at 3–9 bar, to produce a supersaturated (compared with saturation at atmospheric pressure) solution of air in water.
