Description. Dissolved air flotation (DAF) is a proven and effective physical/chemical technology for treating a variety of industrial and municipal process and wastewater streams. DAF systems are commonly used for the removal of oils & greases and suspended solids to meet a variety of treatment goals including: Product recovery and reuse.

Acell = cross sectional area of flotation cell (ft 2) Fgas = gas flow rate (ft 3/min) Agas = total cross sectional area of gas bubbles per unit volume (ft2/ft3) If flotation gas is injected into a unit at the rate of 1 ACF/BBL of produced water, then the Sweep Factor as a function of bubble diameter is as follows:

The flow cross-section slowly decreases and then quickly increases; the water collapses violently and vortices are formed. ... Besides this, the cost and performance of flotation technology using NBs are significantly lower than in normal processes (Han & Dockko 1998; Haarhoff & Edzwald 2001; Han et al. 2006).
