21. Measurement and prediction of dewatering characteristics for mechanical pulpsusing optical fibre analysis
Abstract : On‐line measurement of relevant fibre and pulp characteristics is necessary in order to increase productivity and to maintain uniform quality. The drainage properties within the wire and the press section are important factors since they affect the dry content after the press section. READ MORE

22. Consolidation and Rheology at High Solids Content
Abstract : Paper and board are pigment coated in order to achieve a smooth surface, thereby enhancing the optical and printing properties. In the most frequently used technique, a metal blade is used for metering off the coating colour, which is typically applied by roll or jet application. READ MORE

23. Nutrient management in sewerage systems : investigations of components and exergy analysis
Abstract : The aim of this thesis is to present results from different experiments dealing with components that may be useful to improve nutrient management within sewerage systems. Further, exergy analysis is used to compare the utilisation of physical resources within different alternatives for sewerage nutrient management. READ MORE

24. Filtration of Cellulosic material - the impact of ionic strength and electric field
Abstract : It is crucial that dewatering technology is considered if an economically feasible production of cellulosic materials is to be achieved. Cellulosic materials are often produced in dilute streams and therefore require great amounts of water to be removed to allow for reasonable transportation costs and/or further modifications.

25. Filtration of Microcrystalline and Microfibrillated Cellulose: The impact of ions and electric field
Abstract : Dewatering plays an essential role in the processing of microcrystalline cellulose (MCC) and microfibrillated cellulose (MFC), as their commercial attractiveness in many applications is limited by the high water content of the products. Filtration is the most common mechanical dewatering technique, but the filtration of these materials results in filter cakes with high filtration resistance. READ MORE
