Centrifuge Dewatering Decanters for Sludge Treatment

The waterMaster decanter from GEA is a continuously operating centrifuge with horizontal solid-wall bowl developed specifically for the requirements of dewatering industrial and municipal sewage sludge. The frame is of open design with gravity discharge of the clarified phase.

GEA waterMaster achieves first-class dewatering results whether as a stationary or a mobile unit.

Energy consumption reduced by up to 50 percent

;

In times of rising disposal costs and energy prices, the operating costs of a decanter are becoming more important than ever. GEA waterMaster ensures a uniquely favorable energy balance and first-class separation performance.

The outstanding dewatering efficiency of the waterMaster is based on the following technical features:

  • Minimal power consumption down to 0.7 kWh/m³
  • Highest g-force for maximum dewatering
  • Gentle feed geometry for optimum flocculation and low wear
  • Very sensitive regulation of the torque, even with fluctuating feed conditions
  • Deep-pond design for improved clarification and reduced energy requirement
  • GEA ecodrive with only one frequency converter and elimination of the loss of efficiency
  • GEA summationdrive with intelligent kinematics for high differential speeds and torques
  • Automatic adjustment of the differential speed due to the frequency-controlled variable speed motor
  • GEA energy jets: specially-shaped weir plates with integrated flow deflection for reduced energy requirement
  • All product-contacting parts are made of stainless steel
  • Low space requirement
  • Good accessibility to all components
  • Easy to operate and maintain
