EXPERIMENTAL A softwood (mainly spruce) bleached kraft pulp (SWBKP), and a hardwood (eucalyptus) bleached kraft pulp (HWBKP) were refined in a PFI mill to 470 and 490 ml CSF freeness, respectively. Three grades of commercial aspen high-yield pulp (325/85, 325/83, 250/80) were obtained from Tembec Inc., without further refining treatment. The properties of the pulp samples are listed in Table I....

Optimization and control of the pulp and paper making processes for cost-effective production requires more frequent monitoring of the relevant pulp and stock preparation quality parameters. A new quality monitoring system for pulping and stock preparation is developed. The new online L&W Pulp Tester is a complete wet laboratory with automatic sampling from different positions along the process...

Membrane separation technologies have recently received much attention, from lab-scale studies to full-scale operations, in the forest industry.
