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.
Dissolved air flotation.
The released air forms tiny bubbles which adhere to the suspended matter.
Dissolved air flotation daf is a water treatment process that clarifies wastewaters or other waters by the removal of suspended matter such as oil or solids.
Daf systems are commonly used for the removal of oils greases and suspended solids to meet a variety of treatment goals including.
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 isn t quite as simple.
Dissolved air flotation daf is a proven and effective physical chemical technology for treating a variety of industrial and municipal process and wastewater streams.
