ANDRITZ decanter centrifuge D is a sludge centrifuge made from advanced wear-resistant materials for solid-liquid separation in wastewater and sludge treatment. Handles dewatering and thickening of various sludge types and flow rates. Energy-saving design reduces power use by up to 30%. Includes safety systems and low-noise, low-vibration operation. Available in eight models with solid capacities from 800kg/hr to 25,000kg/hr.

  • Sludge centrifuge for dewatering and thickening in wastewater and sludge treatment
  • Energy-saving features such as TurboJet TM weir plates and regenerative back drive
  • Variable scroll and bowl speeds for easy process adjustment
  • Fast dismantling design for reduced downtime and maintenance
  • Adjustable pond depth and automatic control system for optimum performance
  • High wear protection and minimal additive use
  • Compact in-line design for reduced footprint
