PowerPress belt press for mechanical dewatering, a solution for every need: largest range of belt press (from 1 to 3m), with the largest capacity and dimensions of the market

Solid bowl decanter centrifuge D

Industrial technology adapted for treatment of wastewater sludge

ANDRITZ decanter centrifuges are designed for reduced space requirement and power consumption at comparable throughput.

In sludge treatment technology, ANDRITZ has revolutionized the drive system for decanter centrifuges – following the double drive with energy re-circulation, the new low-power consumption decanter centrifuge features three new technologies:

  • TurboJet weir plates
  • High hydraulic pressure rotor design
  • Direct drive gearbox

The technology is protected by worldwide patents and is used in centrifuges for thickening and/or dewatering WWTP sludge and for several other applications.
