2019-12-1  For a bicyclone flotation column and dissolved air flotation device, the oil droplet size D 50 in the effluent is 3.97 μm and 7.21 μm, respectively. This means that the bicyclone flotation column is especially effective for separating fine oil droplets from the produced water from ASP flooding.

Dissolved Air Flotation - an overview ScienceDirect

Dissolved air flotation operates on the principal of the transfer of floc to the surface of water through attachment of air bubbles to the floc. The floc accumulated on the surface, known as the ‘float’, is skimmed off as sludge (Section 7.19).The clarified water is removed from the bottom and is sometimes called the subnatant or ‘floated’ water.
