11. A Model for Simulation of Fiber Suspension Flows
Abstract : The fiber suspensions in the production line from wood topaper are subjected to many types of chemical and mechanicalprocesses, in which the flow of the suspension is of vitalimportance. The flow of the suspension determines the degree ofuniformity of the fibers through the processing, which inreturn affects the properties of the fiber suspension. READ MORE

12. Compression uniformity measurements on coated anduncoated paper surfaces
Abstract : Paper is exposed to compressive stresses at several occasions in its production process and in subsequent printing operations. In the press section of a paper machine, the fibre web is mechanically dewatered by compression. READ MORE

13. Dissolved Air Flotation and Microscreening for Particle Separation in Wastewater Treatment
Abstract : Particle separation is one of the fundamental processes in wastewater treatment and a good understanding of the basic separation mechanisms ? sedimentation, flotation and filtration ? is critical in the design of wastewater treatment systems. Upgrading of treatment plants for enhanced primary treatment and effluent polishing are current examples of applications where effective, high-rate separation methods are of interest. READ MORE

14. Orientation of elongated particles in shear and extensional flow
Abstract : Elongated particles in fluid flows are a big part of the world we are living in. Gaining knowledge on how particles behave in different fluid flows can potentially increase the efficiency of industrial processes and decrease the world's energy consumption as well as improve the properties of future materials.

15. A passage to wastewater nutrient recovery units : Microalgal-Bacterial bioreactors
Abstract : In recent years, the microalgal–bacterial process has been considered to be a very attractive engineering solution for wastewater treatment. However, it has not been widely studied in the context of conventional wastewater treatment design under Swedish conditions. READ MORE
