  • Dissolved air flotation

    Dissolved air flotation

    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. The released air forms tiny bubbles which adhere to the suspended matter

    Dissolved Air Flotation (DAF) systems are designed to remove suspended solids (TSS), biochemical oxygen demand (BOD 5), and oils and greases (OG) 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.

    How Dissolved Air flotation Systems for Water Treatment

    Dissolved air flotation (DAF) is a water treatment process for removing oils, solids, and greases from a water supply. The process helps clarify wastewaters by eliminating different types of suspended matter. DAF dissolves air in pressurized water then releases it at atmospheric pressure.

    Dissolved air flotation involves the creation of tiny air bubbles that collect waste particles as they float to the surface. Traditional systems require mechanical scrapers for the separation of flotation sludge whereas our advanced DAF system design does not require mechanical skimmers or motors.
