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.

Water, Wastewater Test Kits Testing Process

Dissolved air flotation in solids-liquid separation is implemented through the introduction of micron-sized gas (usually air) bubbles into the liquid phase. As the micro bubbles attach to the solids, the resultant buoyant force of the combined solid-gas causes the matrix to rise to the surface where it is collected.
