Decanters

LeveL-21 decanters are used to remove the near-surface clear water layer at the end of a treatment cycle in an SBR plant. Decanting describes the sludge-water separation step in the SBR process. In the SBR process, the clear water discharge / decanters assume the function of the secondary clarifier and are therefore of absolutely decisive importance for the effluent quality. Their function is essentially determined by the solids content in the effluent of the treatment plant.

LeveL-21 decanters have been specially designed to meet the process-specific requirements of the SBR process.
The floating design in combination with a submerged and completely horizontally aligned inflow area ensures that only the clear water layer
reaches the effluent of the wastewater treatment plants. Turbulences are excluded by the very conservative design of the aggregates.
Different design options with and without own pressure increase allow the adaptation of the units to different hydraulic and wastewater
technical specifications.

Pump decanter with PE floating body

LeveL-21 Pump decanters are used to draw off the near-surface clear water layer at the end of a treatment cycle in an SBR plant by gravity with the aid of an integrated pump:

 

  • Discharge systems: flexible hose as pressure line to the tank edge
  • Submerged outlet below the water surface: safe retention of floating materials
  • Capacity range: 25 m3/h or 50 m3/h
  • Horizontally opened inflow area: no suction of previously sedimented sludge
  • Floating design: always optimum distance to the sludge level
  • Materials: Submersible pump stainless steel, float and weir PE

Stainless steel decanter

LeveL-21 steel decanters are used to draw off the near-surface clear water layer at the end of a treatment cycle in an SBR plant by gravity:

 

  • Individual outlet systems: flexible hoses or stainless steel pipe systems as telescope or swivel joint system
  • Submerged outlet below the water surface: safe retention of floating materials
  • Wide performance range: from 10 m3/h to > 1500 m3/h
  • Horizontally opened inflow area: no suction of previously sedimented sludge
  • Floating design: always optimum distance to the sludge level
  • Materials: stainless steel 304 or 316

EMC stainless steel decanter

LeveL-21 EMC-Decanters are used to draw off the near-surface clear water layer at the end of a treatment cycle in an SBR plant by gravity:

 

  • Additional automatic sealing system: prevents activated sludge from entering the system during mixing and aeration and minimizes the discharge of filterable substances.
  • Individual outlet systems: flexible hoses or stainless steel pipe systems as telescope or swivel joint system
  • Submerged outlet below the water surface: safe retention of floating materials
  • Wide performance range: from 10 m3/h to > 1500 m3/h
  • Horizontally opened inflow area: no suction of previously sedimented sludge
  • Floating design: always optimum distance to the sludge level
  • Materials: stainless steel 304 or 316
