Dissolved Air Flotation

Dissolved Air Flotation Systems & Equipment

Dissolved air flotation (DAF) systems and equipment use a separation or clarification process to remove suspended solids, grease, or oils from a solution by injecting air into the liquid stream.

These microbubbles attach to solids lifting them to the top of the tank where they can be removed by a surface skimming conveyor.

Your fluids enter the DAF system through a connection located on the tank that controls the flow rate of the incoming solution.

At this connection, pressurized air is injected into the fluid stream creating the dissolved air. These microbubbles begin to form in the fluid once in the atmospheric tank.

Microbubbles travel to the top of the tank providing a path to float the solids to the top of the tank where a continuous running chain and flight conveyor pull the sludge from the top and place it into a hopper.
