Dissolved Air Flotation (DAF) Systems Fluence

Dissolved Air Flotation. DAF is a wastewater clarification process for the separation of solids, grease, and oils. The system helps concentrate sludge, removes a wide range of suspended solids (fats, oil, and grease) in wastewater and reduces COD and BOD. Our dissolved air flotation solutions provide high quality, high capacity, and efficient clarification.
