OP Stage

Peroxide Stages are suitable for the bleaching of both softwood and hardwood kraft pulps.

Pressurized hydrogen peroxide bleaching processes that are very efficient for brightness increase. This means that this technology normally should be an integral part of every new bleaching line design. The PHT stage is a lower cost alternative to the PO and OP stage achieving similar results and is very attractive for retrofits of existing bleaching stages. Pressurized peroxide stages are without question the first choice for bleaching of sulphite pulps as it has proven very effective.

Benefits of using peroxide in bleach plant:

  • Increased brightness ceiling
  • Savings of chlorine dioxide
  • Reduced AOX discharges to effluent
  • Increased bleach plant flexibility
