Efficient flotation with maximum aeration rate

Paper, board and tissue makers rely on Valmet Flotation technology to remove ink, ash and microstickies from pulp. 

A successful flotation process removes high levels of ink while minimizing secondary stage fiber losses and overall chemical consumption.  Valmet’s OptiDeink Flotation technology delivers a stable solution that helps mills achieve their flotation goals with 20% better aeration and easier maintenance than conventional technology.

Key features of OptiDeink Flotation:

• Compact design to help mills save space/footprint
  • Layouts available for both primary and secondary stages in both pre-and-post flotation
• Unique cell design with common control levels for optimized flows
• Optimized injector jet nozzles (providing increased jet surface area and maximum air aspiration flow) for better ink removal
• Efficient drainage of froth
• Easy access to air chambers and jet nozzles provide easy maintenance
