Duluth Recycled Pulp Mill, 2002 Fall Technical Conference
Duluth Recycled Pulp Mill is a POWER POINT presention on the "Two Stage"
Bleaching Process used by this 135,000 square foot recycled pulp plant.
Producing 90,000 tons of recycled pulp per year, with the majority of scrap coming from upper midwestern states, this mill has developed a Two Stage bleaching system Hydrogen Peroxide and Sodium Hydrosulfite, that insures the required brightness gain and helps to absorb the variabilty of incoming raw materials.
