Induced Air Flotation: An advance in clearing wastewater

Induced Air Flotation (IAF) is a significant advance on dissolved air flotation (DAF); IAF is more efficient and far less costly to operate and maintain. Also, bubble size can be easily varied to accommodate variation in feed, unlike DAF.

Flotation Chemical Engineering scribd

In wastewater or water treatment the floc is not generally strong enough for the high shear induced by propellers or high air pumping rate. Dissolved Air Flotation (DAF) In this case the suspension is saturated with air at high pressure (40-50 psig). This suspension is then pumped to a flotation chamber at 1 atm (14.7 psi).

Flotation. Flotation involves separation of solids from the water phase by attaching the solids to fine air bubbles to decrease the density of the particles so that they float instead of sinking. The rising solids are called the "float". The float is skimmed off the surface and further processed in the sludge train.. Advantages of flotation over sedimentation:
