Liqui-Fuge Wedge-Wire Rotary Drum Screen Design Features

  • Wedge-wire drum
  • Internal and external spray system
  • Flow distribution tray
  • Support structure with trunnion wheels

Liqui-Fuge Wedge-Wire Rotary Drum Screen Operation

Flow is pumped to the distribution tray where it is directed onto the rotating drum. Wastewater passes through the openings in the drum while the captured screenings remain on the drum surface. Radial flights inside the drum transport the screenings towards the discharge end of the drum. The screenings exit the unit and fall into a post screening device or a container. Spray water cycling is adjustable to ensure maximum performance.
