Abstract
High-consistency bleaching with peroxide and ozone was investigated in the laboratory and pilot plant. For the ozone stage, the influence of consistency in the range of 30 to 45% and the influence of fluff qual ity and ozone charge on Kappa number brightness and strength propertie s were investigated. The laboratory and pilot plant operation showed c omparable results. In HC-peroxide bleaching good mixing was only possi ble in mill and pilot plant scale. The influence of consistency and ca ustic was measured.
