  • A New Decision Model for Reducing Trim Loss and

    In the paper industry, numerous studies have explored means of optimizing order allocation and cutting trim loss. However, enterprises may not adopt the resulting solutions because some widths of the inventory exceed or are less than those required for acceptable scheduling. To ensure that the results better suit the actual requirements, we present a new decision model based on the adjustment

    01/10/2016· The neutralization of wastewater by GLD may also cause operational problems by increased recirculation of NPE as a result of burning the wastewater sludge in the recovery boiler. Zambrano et al. (2010) performed composting experiments with Kraft mill secondary sludge, by using GLD as a pH-stabilizing additive. Their results show that the sufficient dosage of dregs is

  • Troubleshooting Activated Sludge Processes Introduction

    Review of the literature shows that the activated sludge process has experienced operational problems since its inception. Although they did not experience settling problems with their activated sludge, Ardern and Lockett (Ardern and Lockett, 1914a) did note increased turbidity and reduced nitrification with reduced temperatures. By the early 1920s continuous-flow systems were having to deal

    In the mill of the future, pulping will be done with energy-efficient digesters that promote extended delignification and with additives that enhance the pulping yield. Pulp will be bleached in closed or semiclosed bleach plants. These plants will require relatively small amounts of bleach chemicals with much of the spent liquors being recycled before they are sent through the Kraft recovery
