Decanter Centrifuge for biosolids dewatering and thickening

GEA biosolids Decanter

The GEA biosolids Decanter is a continuously operating centrifuge with a horizontal solid-wall bowl, specifically designed for (pre)dewatering and thickening of municipal sludge.

Decanter pro series

Optimum dewatering reduces costs for sludge disposal

Optimal, economical dewatering of sewage sludge is a key step in all disposal methods, including incineration, landfilling, and agricultural land application.

In practice, having less sludge to dispose of saves transportation costs and reduces energy consumption for drying and incineration, thereby reducing CO2 emissions.

The GEA biosolids Decanter ensures a high level of dewatering with significantly reduced sludge volumes, e.g. through high g-force for optimum separation and process-optimized torque control.

Efficiency through technical features

  • Deep pond design for maximum separation efficiency
  • Gentle feed geometry for optimum flocculation and low wear
  • All product contact parts are made of stainless steel
  • Minimal space requirements (m3/h per m2)
  • Easy access to all components
  • Easy to operate and maintain
