Dewatering

Improved mechanical dewatering offers energy savings, higher productivity and improved runnability during the production of paper and board. Research in this field is performed at Innventia to achieve these goals. We strive to make dewatering in paper, board and pulp machines more efficient, while maintaining – or even improving – the product properties.

Unique equipment

We have a wide variety of equipment available to perform our research and commission work, much of which is unique. This includes:

  • Britt dynamic drainage jar
  • Higher pressure drop sheet former
  • Dynamic laboratory suction box
  • Laboratory pressing/drying simulator
  • Pilot paper machine FEX
  • High speed thermography
