Dissolved Air Flotation an overview ScienceDirect Topics

In dissolved air flotation (DAF), bubbles are produced when the dissolution of air in water occurs under very high pressure. In this method, bubbles’ diameter typically ranges between 10 and 100 μm (Chen et al., 2011; Naghdi and Schenk, 2016).

Installation, Operation & Maintenance Manual

2013-11-5  A DAF (Dissolved Air Flotation) system creates microscopic air bubbles that are attached to incoming wastewater particles in order to float them. Once floated, they are separated from the wastewater and skimmed from the top and into the float scum chamber. The treated wastewater then exits from near the bottom of the DAF.
