  • Design and Sizing of a Dissolved Air Flotation Separator

    2020-08-04· Dissolved Air Flotation Theory of Operation. If you are unfamiliar with basic DAF separator design principles, a review of the "Dissolved Air Flotation Theory of Operation" might prove helpful.This basic document covers Stokes' law and other basic separation concepts.

  • Dissolved Air Flotation an overview ScienceDirect Topics

    Dissolved air flotation operates on the principal of the transfer of floc to the surface of water through attachment of air bubbles to the floc. The floc accumulated on the surface, known as the ‘float’, is skimmed off as sludge (Section 7.19).The clarified water is removed from the bottom and is sometimes called the subnatant or ‘floated’ water.

  • Dissolved Air Flotation System for Wastewater Treatment

    Dissolved Air Flotation (DAF) is a physical stone separation technique used to remove suspended solids and fats, oils and grease from the wastewater. Using a Dissolved Air Flotation system for wastewater treatment is a common technique across a range of markets; including the stone and beverage, plastics recycling and pulp and stone industries, to name a few.

  • Dissolved Air Flotation (DAF) Systems Evoqua

    2020-08-04· Dissolved Air Flotation (DAF) systems are designed to remove suspended solids (TSS), biochemical oxygen demand (BOD 5), and oils and greases (O&G) from a wastewater stream. Contaminants are removed through the use of a dissolved air-in-water solution produced by injecting air under pressure into a recycle stream of clarified DAF effluent.


    Dissolved Air Flotation (DAF) systems are a great way to remove positively and neutrally buoyant liquids and particulate from a waste stream. This removal method is a time tested and economical treatment solution for the removal of

  • DAF (Dissolved Air Flotation) MICHIGAN TECHNOLOGY

    DAF (Dissolved Air Flotation) technology is mainly for removing suspended solids. Suspended solids and phosphate in wastewater are coagulated/flocculated to bigger and less dense flocs. The generated flocs flow to flotation tank. Air is dissolved in water which is recycled from part of treated water under 3~5 atm, then released to the flotation tank under atmospheric condition.

  • Dissolved Air Flotation System (DAF) Hoffland

    Dissolved Air Flotation Systems. HEI manufactured dissolved air flotation systems (DAF) efficiently separate total suspended solids (TSS) and fats, oils, and grease (FOG) particles from industrial effluents.. Air is dissolved in the treated water by the addition of compressed air to a pressurized stream of recycled effluent. The pressurized water then passes through a pressure relief valve
