Valmet Disc Filter CDI

Fiber recovery and thickening for high freeness applications

Valmet Disc Filter CDI recovers fiber from white water while thickening broke or recycled pulp from medium to large flows.  Its unique open rotor design enables the filter to seamlessly handle changes in feed consistency, flow and freeness.

The open grid sector design features more than 90% open area, minimizing the accumulation of pulp and debris within the sector for less cleaning and longer use. Engineered and built with maintenance in mind, Valmet Disc Filter CDI provides easy access to open grid sectors for cleaning and serviceability.  Other benefits derived from the open rotor design of the CDI disc filter include:

  • High hydraulic capacity
  • Minimum space requires
  • Reliability
  • Faster, easier maintenance
