    Flotation: DAF, IAF, SAF Veolia Water

    3. Induced air flotation (IAF) involves saturating the wastewater with air either directly in an aeration tank or by permitting air to enter on the suction side of a pump or with a venturi. The partial vacuum, which is applied, causes the dissolved air to come out of solution as minute bubbles. 4. Suspended air flotation (SAF) is a newer ...

    pumped through an eductor and air is drawn into the flow, to be released as it enters the bottom of a separating vessel. Bubbles created in this way are rather larger than those created by the second option of dissolved air. IAF plants are generally used where low levels of contamination are present.

    Clean effluent is pressurized with air and released into a flotation cell containing fluids with <= % solids. Using dissolved air flotation at a water or wastewater treatment plant, the recycle rate is the percentage of the pressurized effluent that is to be applied to the influent. Example: If treatment plant recycle rate is known to be at 40%.
