ANDRITZ PreFiltration Technology

Best choice for difficult operating conditions

Are you looking for a pusher centrifuge that allows maximum efficiency while still maintaining a high level of flexibility towards changes upstream, such as fluctuations in flow, solids concentration, or particle size? Under these conditions, conventional pusher centrifuges typically have to be either oversized or equipped with additional upstream equipment, for example cyclones or thickeners. 

The ANDRITZ PreFiltration Technology adds an internal thickening stage to the machine and thus doubles the liquid capacity, which makes the ANDRITZ pusher centrifuges very flexible in operation. How does it work? Find out more:

Krauss-Maffei pusher centrifuge SZ

Wide range of applications

The PreFiltration Technology can be used in all existing fields of application for pusher centrifuges and also paves the way for new applications:

  • High-viscosity mother liquor
  • Improved performance with small particle sizes
  • Solids with difficult dewatering properties
  • Low solids concentration down to 10%

Your benefits

There are several benefits due to the internal thickening stage and the resulting increased liquid capacity:

  • Greater flexibility to deal with fluctuating upstream conditions
  • Supersedes upstream thickening equipment
  • Technology suitable for retrofitting
