AquaDAF® Dissolved Air Flotation High-Rate Clarifier

High - Rate Clarification
Membrane pretreatment
Algae Removal


AquaDAF®* is a high-rate clarifier utilizing dissolved air flotation for low turbidity surface and algae laden waters.The AquaDAF® clarifier’s uniquely engineered effluent collection system provides operating rates unequaled by conventional flotation technologies.
The result: Increased capacity for existing or new treatment facilities with no minimal space required.


Dissolved air flotation (DAF) is an excellent solution for clarifying water with high levels of algae and other low-density solids that cannot be removed efficiently with sedimentation. The AquaDAF® clarifier combines conventional Dissolved Air Flotation (DAF) principles with several enhanced components, including a unique effluent collection system. This and other process improvements allow efficient hydraulics within the DAF flotation zone at superior surface loading rates.
