16. Sustainable Development: Implementation in Urban Water Systems
Sammanfattning : As Sustainable development, a widely used but poorly understood term, challenges traditional scientific values such as prediction and control, scientists have tried to manipulate the concept to promote their own particular agendas. Thus, it has suffered from misrepresentation which has prevented the concept from being fully implemented at a practical level. LÄS MER
17. Application of indigenous materials in drinking water treatment
Sammanfattning : Volcanic ash and Moringa oleifera (M. oleifera) were investigated as indigenous materials for drinking water treatment based on problems identified at Kampala and Masaka water treatment plants in Uganda. LÄS MER
18. When water becomes a threat : Risk assessment and risk management plans for floods and drinking water in Swedish practice
Sammanfattning : Water is an essential but vulnerable resource. A shortage of good quality drinking water is a threat to human health and society as a whole. Abundance of water in the form of floods can also be a serious threat which can have consequences for the drinking water supply. To reduce these risks there is a need for systematic risk reduction.

This thesis focuses on information management, institutional arrangements and strategic policy support, with special reference to the EU Water Framework Directive (WFD). LÄS MER
20. Coupled Hydrological and Microbiological Processes Controlling Denitrification in Constructed Wetlands
Sammanfattning : Treatment wetlands play an important role in reducing nitrogen content in wastewater and agricultural run-off water. The main removal process is denitrification and the removal efficiency depends on the hydrological and microbiological features of the wetland, especially in terms of water residence times and denitrification rates.
