AquaDAF* Clarifier

Effectively remove algae and low-density solids for drinking water treatment

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 by sedimentation.

The AquaDAF* clarifier combines conventional 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.

AquaDAF Features

  • Compact footprint due to high loading rates up to 20 gpm/ft2
  • Flexible layout options, customized to any size plant
  • Retrofit existing sedimentation basins to increase capacity of existing plants
  • Ideal for membrane pretreatment since polymer typically is not required
  • Efficient for cold water clarification
  • Start-up and shut-down within minutes
  • Hydraulic or mechanical sludge removal options
  • Clarified turbidity < 1 NTU, and algae removal greater than 90%
  • Thickened sludge 2-4%
