Flotation: DAF, IAF, SAF Veolia Water

Flotation: DAF, IAF, SAF By Dave Christophersen, Vice President/Technical Manager Flotation is a method of separating solids or liquids from water by introducing fine gas bubbles. The bubbles attach to the particulate matter, and the buoyant force of the combined particle and gas bubbles is great enough to cause the particle to rise to the surface.

Microflotation Wikipedia

Microflotation is a further development of standard dissolved air flotation (DAF). Microflotation is a water treatment technology operating with microbubbles of 10–80 μm in size instead of 80300 μm like conventional DAF units. The general operating method of microflotation is similar to standard recycled stream DAF units.
