Developments since 1920 include multistage bleaching of kraft bleaching with peroxides, chlorine dioxide, and sodium hypochlorite use of synthetic resins for wet-strength paper for bags, maps, etc. and use of soluble bases for sulfite pulping, which allow the use of more species of wood. [Pg.1368]

Free (TCF) processes. The ECF processes substantially eliminated the formation of chlorinated organics in kraft bleach effluent. Both ECF and TCF processes also reduce the BOD and COD of bleach effluent significantly, since the same process, which oxidized the lignin fragments in the pulp also produced largely oxidized products from these. This gave a lower overall oxygen demand from the effluent, which made it much less expensive to treat. [Pg.489]

P. chrysosporium has not been well studied. Our information concerning this process comes from the following (1) In studies of the decolonization of the alkaline extract (E ) obtained from a Kraft bleach plant, it was demonstrated that many of the organochlorldes originally present were removed by treatment with P. chrysosporium in a rotating biological contactor (6,7). Furthermore, most... [Pg.344]

The cohesive force between cellulosic fibers from Kraft bleached pulp was also measured in solutions of a cationic surfactant, tetrabutylammonium iodide (TBAI). The cohesive force, p, as a function of the concentration of TBAI is shown in Figure 2.25. As seen in this figure, the cohesive force undergoes a sharp decrease as the TBAI concentration increases and then passes through a... [Pg.70]
