Wastewater Air Flotation Skimmers

Dissolved Air Flotation (DAF) Systems

Dissolved air flotation (DAF) is a proven and effective physical/chemical technology for treating a variety of industrial and municipal process and wastewater streams. DAF systems are commonly used for the removal of oils greases and suspended solids to meet a variety of treatment goals including: Product recovery and reuse.

DAF Dissolved Air Floatation in Wastewater

 · DAF is a water wastewater treatment system which remove contaminants like oil and suspended solids. In DAF system wastewater is treated by dissolving air in wastewater under pressure and then released at atmospheric pressure in a floatation tank basin. It is one of the most effective and versatile process in water treatment.

Dissolved Air Flotation

Dissolved air flotation is a water treatment process that clarifies wastewater by removal of suspended solids, oils, greases, BOD, COD, and metals. This is achieved by dissolving air in the wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank.

Scum Pipe System

Also called rotating scum pipes, scum skimmers, rotating pipes or rotating troughs, these systems are employed all over the world in circular and rectangular clarifiers, dissolved air flotation basins, settling basins, and other process basins where surface scum is an issue.

About Dissolved Air Flotation

Dissolved air flotation (DAF) clarifiers remove suspended solids from are a costeffective alternative to conventional sedimentation clarifiion processes. The advantages of DAF clarifiers are their ability to treat a wide range of suspended solids in water at a high rate of solids removal and for wastewater sludge thickening.

Dissolved Air Flotation system (DAF) is next in the process. The DAF system can remove up to 80% of fat, TSS (Total Suspended Solids), BOD, COD and TN loads from the wastewater (Babatola et al ...

Dissolved Air Flotation DAF Systems

In PWL DAF systems, wastewater is introduced into the DAF tank and processed in a flowthrough manner – wastewater comes in one side and goes out the other. While many DAF system designs push sludge across the entire length of the tank in the same direction as the wastewater flow, FRC's PWL design uses a skimmer assembly that rotates against the the hydraulic flow of the water.

Dissolved Air Flotation (DAF) has been known as one of the most effective and robust ways to remove suspended solids (TSS), biochemical oxygen demand (BOD 5), fats, oils and grease (FOG), phosphorus (P) or nutrients from industrial response to variations in industrial activity, variations in wastewater and water streams and the everdemanding .

Dissolved Air Flotation (DAF)

Dissolved Air Flotation (DAF) systems are designed to remove suspended solids (TSS), biochemical oxygen demand (BOD5), and oils and greases (OG) from a wastewater stream. Contaminants are removed through the use of a dissolved airinwater solution produced by injecting air under pressure into a recycle stream of clarified DAF effluent.
