ANDRITZ’s scope of supply encompasses:

  • Modernization of the brownstock washing process, including a new multi-stage DD-Washer with compact layout
  • A new oxygen delignification stage for optimizing the kappa level to achieve highest possible yield and minimum chemical consumption
  • Relocation of the existing screening process after the oxygen delignification stage in order to minimize fiber losses
  • Bleaching plant modernization by changing the existing 5-stage bleaching system to 4-stage bleaching
  • Cooler for digester blow temperature control

ANDRITZ has several hundred very successful DD-Washer installations as references around the globe. ANDRITZ DD-Washers are characterized by lowest operating costs and emissions as well as extremely good washing efficiency, based on the required number of displacement washing stages in a single unit. The DD-Washer is also very gentle to fibers, retaining all the bulk, stiffness and strength of the pulp as there is no mechanical pressing during pulp washing.
