Flotation Process - an overview ScienceDirect Topics

Flotation processes are based on the different surface wettability properties of materials (Wang et al., 2015). In principle, flotation works very similarly to a sink and float process, where the density characteristics of the materials, with respect to that of the medium where they are placed are at the base of the separation.

EP2318318A1 - Flotation and separation of flocculated oils ...

Oily and/or solids-containing water is clarified by chemical treatment to form flocculated and agglomerated solid phases and a clear water phase. In the clarification process, microbubbles of air or other gas are introduced at atmospheric pressure, via an eductor or other suitable device, together with a flocculant. During the subsequent formation of floes and their agglomeration into larger ...
