11. The influence of multiscale hyporheic flow on solute transport : Implications for stream restoration enhancing nitrogen removal
Sammanfattning : Stream water that flows into and out of streambeds is called hyporheic exchange flow (HEF).It continuously interacts with groundwater and thereby affect the water quality of local streamreaches as well as downstream recipients by providing an environment where solutes andenergy can be retained and degraded.

12. Spatial variability of geogenic contaminants in drinking water sources : Insights into hydrogeological controls, geospatial data for safe water supply and groundwater resource management
Sammanfattning : The presence of geogenic contaminants in drinking water is a major health concern in many parts of the world. The interaction of groundwater with different rock types and sediments in the natural geochemical environment play an important role in controlling their mobility. LÄS MER
13. Uncharted Waters : Non-target analysis of disinfection by-products in drinking water
Sammanfattning : Disinfection by-products (DBPs) are potentially toxic compounds formed when drinking water is treated with disinfectants, such as chlorine or chloramine. A large proportion of the exposure to DBPs is still unknown and the health risks observed through epidemiological studies cannot be explained by DBPs known today. LÄS MER
14. Anammox-based systems for nitrogen removal from mainstream municipal wastewater
Sammanfattning : Nitrogen removal from municipal wastewater with the application of deammonification process offers an operational cost reduction, especially if it is combined with a maximal use of organic content of wastewater for biogas production. In this thesis, two approaches for integration of the deammonification process into the municipal wastewater treatment scheme were studied. LÄS MER
15. Protein-water interactions studied by molecular dynamics simulations
Sammanfattning : Most proteins have evolved to function optimally in aqueous environments, and the interactions between protein and water therefore play a fundamental role in the stability, dynamics, and function of proteins. Although we understand many details of water, we understand much less about the protein-water interface. LÄS MER
