Dissolved Air Flotation

Dissolved Air Flotation (DAF)

Dissolved Air Flotation over Filters (DAFF)

  • robust, high rate stable process
  • integrated flocculation, flotation and filtration packages to 5ML/d

dissolved-air-flotation

Applications

  • potable water
  • industrial and mining
  • tertiary waste water
  • solids thickening

DAFF upstream of membrane filtration plant

  • “multiple barrier” process with redundancy
  • membrane protection
  • beneficial whole of life cost

Features

  • process stability
  • small footprint
  • low waste water volumes, high float solids concentration
  • diurnal water temperature variation immunity
  • plenum filter floors
  • combined air/water filter wash
  • automated controls
  • SCADA trends and performance data, remote access
