1. Water powered percussive rock drilling : process analysis, modelling and numerical simulation
Abstract : This thesis is devoted to problems, processes and systems related to the recently developed water powered percussive rock drilling method. The technology, which uses ordinary water to drive down-the-hole hammers, has been used to produce more than 6 million meters of blast holes within the mining industry. READ MORE

2. Application of aerobic granular sludge for municipal wastewater treatment - Process performance and microbial community dynamics under fluctuating conditions
Abstract : Pressures of growing cities, competition for use of urban areas and higher influent loads, are pushing for innovative technologies for wastewater treatment with low demands for land footprint and costs. Furthermore, wastewater treatment is needed to move towards a circular economy by harvest of valuable resources such as nutrients and energy. READ MORE

3. X-Ray Investigations of the Liquid-Liquid Critical Point Hypothesis in Supercooled Water
Abstract : This thesis presents experimental x-ray scattering studies on supercooled liquid water. A liquid-liquid transition between two structurally distinct configurations has been found in deeply supercooled water, indicating the existence of a liquid- liquid critical point. READ MORE

4. Making water information relevant on local to global scale – the role of Information Systems for Integrated Water Management
Abstract : Relevant information is essential for finding solutions in Integrated Water Management (IWM). Complex water systems and a need for increasing integration of sectors, actors and scales in IWM require new methods for developing and managing such information. READ MORE

5. Experiments with sand slurries pumped in 0.1 to 0.5 m diameter pipeline loops
Abstract : The overall objective was to investigate the effectiveness of using high solids concentrations when transporting sand slurries in pipelines with centrifugal pumps. In detail, the aims are to present large-scale experimental pipe friction loss results and how head, efficiency and net suction head performance are influenced by the solid particles in large pumps and to compare friction loss data with a design model.
