Learn MoreDissolved Air Flotation Systems
Dissolved Air Flotation systems effectively remove TSS, FOG, and other pollutants from wastewater. Conceptually, the DAF process is simple tiny bubbles attach to solid contaminants causing them to float and then sludge is skimmed off the surface of the water but designing a DAF system for a real world application isnt quite as simple.
Learn MoreDissolved Air Flotation an overview ScienceDirect Topics
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.
