SBR Decanters

Aqua Turbo and ATB Decanters



Floating (SBR) decanters are typically used to discharge the clear water layer at the end of a treatment cycle in SBR plants and decanters are available for discharge by gravity or pumping and also with or without an additional automatic closing system.


  • Simple and Robust equipment
  • Simple and easy installation
  • Ideal solution for SBR Reactors
  • Different discharge piping systems: flexible hoses or stainless-steel pipes
  • Discharge below water level: no floatables are aspirated from the surface during decanting
  • Wide range: available from 10 m3/h to > 2,000 m3/h
  • Horizontal inflow weir: no aspiration of settled sludge after sedimentation
  • Floating design: always the best distance to the sludge blanket
  • Huge inflow opening: no unattended turbulences
  • Automatic closing system (option): no entry of particles during mixing and aeration in the basin
  • Materials: stainless steel AISI 304 or 316
  • 4 possible executions
  • Decanting with discharge by gravity
  • Decanting with discharge by pump
  • Decanting with mechanically closing system and discharge by gravity
  • Decanting with mechanically closing system and discharge by pump
