Valmet Bleaching Optimizer


Base calculations and controls to stabilize the process:

  • Chemical dosage controls (if not in base automation)

  • Washing water flow controls

  • Production rate control

  • Retention time calculations

Model based quality control (all bleaching stages):

  • Kappa and/or brightness control

  • pH controls

  • Temperature controls

Management of changes:

  • Production rate, pulp grade, and wood species

Management of disturbances:

  • Process event tracking

  • Retention time estimator

  • D2C (Smart continuous measurement)


  • Final pulp brightness at the desired level with reduced variability

  • Minimized loss in pulp strength

  • Bleaching chemical savings

  • Increased production

  • Smooth process operation

  • Fewer production disturbances

  • Elimination of human errors

  • Lower effluent load (COD, AOX)

  • Help in operator work
