Flotation Process - an overview | ScienceDirect Topics

The flotation process depends on several design and operational variables. We consider a superstructure that includes the following three flotation stages: the rougher, which processes the feed; the cleaner, which generates the final concentrate; and the scavenger, which generates the final tailing, as shown in Fig. (1) .

Dissolved Air Flotation Process in Wastewater Treatment

Dissolved air flotation (DAF) is a water treatment process designed to remove oils, solids, and greases. In fact, the process helps clarify wastewaters – and other waters – by eliminating different types of suspended matter. The DAF process dissolves air in the water under pressure – then releases it at atmospheric pressure.

Dissolved Air Flotation

Flotation Flotation is described as a gravity separation process in which gas bubbles attach to solid particles to cause the apparent density of the bubble-solid agglomerates to be less than that of the water, thereby allowing the agglomerate to float to the surface. Flotation is employed mainly for the treatment
