1. Mathematical and Experimental Study on Filtration of Solid Inclusions from Molten Aluminium and Steel
Sammanfattning : Aluminum and steel have been the most produced metal and alloy, respectively, for many years. Their extensive use in various industries, their fundamental role in our everyday life, and their excellent recycling characteristics are the major driving forces for development of their production towards more sustainable processes.

2. Dissolved Air Flotation and Microscreening for Particle Separation in Wastewater Treatment
Sammanfattning : 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. LÄS MER
3. Investigation of hard-to-filter materials -Relating local filtration properties to particle interaction
Sammanfattning : Filtration as a means of separating solids from liquids is an important unit operation employedin a range of different industrial sectors, e.g. forest products, mineral, chemical process andpharmaceutical industries to name but a few. LÄS MER
4. The influence of particle properties on cake filtration: Surface structure and surface charge
Sammanfattning : Solid-liquid separation is often a key process step when biomass is used as a raw material, and an energy efficient way of achieving solid-liquid separation is through cake filtration. However, many biomaterials present challenges when they are filtrated due to the formation of compressible filter cakes. LÄS MER
5. Particle transport in human lung : effects of particle size and shape
Sammanfattning : Recent studies have shown that nanoparticles may be more toxic than larger particles of the same material, but the health risks associated with widespread use largely depend on the extent of exposure. When dealing with potentially toxic particles, precautionary measures have to be taken in order to minimize contact. LÄS MER
