Nov 26, 2017flotation process thickening product professional DISSOLVED AIR FLOTATION THICKENER AccessEngineering. In a dissolved air flotation (DAF) thickener, solids and liquid are separated via the introduction of fine gas bubbles (typically air) to the liquid phase. The bubbles attach to solids particles, making them buoyant.

What is DISSOLVED AIR FLOTATION? What does DISSOLVED AIR

In the oil industry, dissolved gas flotation (DGF) units do not use air as the flotation medium due to the explosion risk. Nitrogen gas is used instead to create the bubbles. The feed water to the DAF float tank is often (but not always) dosed with a coagulant (such as ferric chloride or aluminum sulfate) to coagulate the colloidal particles and/or a flocculant to conglomerate the particles into bigger clusters.
