About Dissolved Air Flotation Units (DAF)

Dissolved Air Flotation Units are used in water and wastewater applications to take solids from other liquid solids separation processes and thicken the solids prior to further dewatering. The drive is mounted on the walkway or bridge. The rotating portion of the drive turns a structural torque tube or shaft, which in turn rotates the solids removal mechanism.

The saturation system receives clarified effluent from the DAF and is saturated by incoming pressurized air to create microbubbles which, in turn, are injected into the DAF unit to float the solids to be removed my multiple skimmers.  The float is transported to a float box for further dewatering.

DAF units can come in circular and rectangular configurations.


3D Models of Every Project

ClearStream produces a 3D model of every unit which we manufacture. These models are extremely valuable to ensure proper fit up. In addition, these models can be a useful tool for operators training and understanding of the unit design and operation. ClearStream provides these 3D models as well as the means for clients to view and manipulate these models at their own site or offices. This affords operations and maintenance personnel with a unique opportunity to “inspect” the unit prior to any planned maintenance without having to drain the tank.
