Dissolved Air Flotation (DAF) System Chemkimia Sdn

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewater by removing suspended solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank. DAF are incorporated when the sludge is less dense than water, or is neutrally buoyant.
