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.
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.

GEA EnergyJets
Boost efficiency and cut energy costs
Discharging clarified liquids in decanter centrifuges requires substantial energy. GEA EnergyJets offer a smart, energy-saving solution to optimize this process.
By combining weir plates with advanced flow deflection technology, EnergyJets can reduce energy consumption by up to 25%, depending on the hydraulic flow rate.
As part of GEA’s ongoing commitment to sustainability, EnergyJets are now a standard feature in the GEA biosolids Decanter series. Designed to handle high liquid loads, these decanters recover valuable energy that would otherwise be lost, improving overall efficiency and lowering operational costs.
GEA biosolids Decanter pro
Resource efficient solution
As one of our most resource-efficient solutions, our GEA biosolids Decanter pro series carries the Add Better label.*
Depending on the machine size, the GEA biosolids Decanter pro series offers energy savings of 15 to 60 percent.
The Add Better label is validated by TÜV Rheinland and based on a calculation and documentation process that meets ISO 14021. The design of the pro series focuses on modularity, energy-efficient product handling, efficient use of electric motors, and the latest gear technology.
*The Add Better label relates to the serial product GEA biosolids Decanter pro released between 2018 and 2022. The comparison refers to the predecessor models.
