Dissolved Air Flotation an overview ScienceDirect

COCO DAFF ® (counter-current dissolved air flotation filtration) is an innovative combined flotation–filtration design in which air and water flow counter-current as against co-current in the conventional dissolved air flotation process (Fig. 7.6 and Plate 12(b)). Air is introduced with recycle water across the total tank sectional area below the flotation zone and therefore only the filter surface loading rate should include the recycle flow.

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.

Research on CFD numerical simulation and flow field

2018-1-2  From the flow hydraulic characteristics simulation of air flotation of three influent water flows (0.4 m³/h, 0.5 m³/h, and 0.6 m³/h), we can see that when the water flow is high, the separation zone reflux and swing is obvious, and the turbulence is large and easily leads to floc fragmentation and desorption, which affects floc flotation.
