Valmet Peroxide Residual Measurement

Peroxide ResidualThe measurement concept designed in Valmet Peroxide Residual Measurement (Valmet Polarox5 FP) utilizes the proven method, in a new innovative way: it measures both total peroxide residual and OOH– ion residual and thus reveals more intimate information of the process conditions. 

Features

The main handicaps of current peroxide stage controls, peroxide over charging caused by low pH or caustic overdosing due to high pH, can be now avoided by measuring total peroxide and OOH– ion ratio online. Based on the enhanced measurement capacity of Valmet Polarox5 FP, new P-stage control concepts can be implemented for best achievable final brightness target with the optimal caustic and peroxide charges.

Benefits

  • Unique measurement
  • Both active and total peroxide
  • Easy and safe installation and start-up
