My TAPPI Story: Rory Wolf

100% substitution of chlorine dioxide to replace chlorine is now a well-known technique very efficient to produce high quality and full brightness kraft pulps while decreasing the impact on the environment. New reglementations are being implemented all over the world and they will result in process changes in the bleach plant. With more stringent regulations concerning AOX, ECF bleaching sequences with chlorine dioxide have to be optimized in order to respect these new regulations. Different ways to increase ClO2 efficiency and to reduce AOX formation have already been described : - Multi-step Process with high/low pH techniques (1) - Decrease of the kappa factor and use of H2 O2 (2,3) The objective of our study was to investigate the effect of different variables on the efficiency of the ClO2 stage and to see which way can be the most efficient to reduce AOX levels.
