   Sammanfattning : Lake Tana Basin is of significant importance to Ethiopia concerning water resources aspects and the ecological balance of the area. The growing high demands in utilizing the high potentials of water resource of the Lake to its maximal limit, pictures a disturbing future for the Lake. LÄS MER

3. 12. Risk-based management of the cost to society from infiltration and inflow to wastewater systems

   Författare :Anna Ohlin Saletti; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sewer system; infiltration and inflow I I ; uncertainty; wastewater; risk management; decision support;

   Sammanfattning : The wastewater system is an important part of our infrastructure as it protects public health and the environment. Well-functioning maintenance is essential to sustain the functionality of the system. LÄS MER

4. 13. Advancing the Implementation of Protective Measures for Drinking Water Sources in Sweden

   Författare :Nadine Gärtner; Chalmers tekniska högskola; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; water protection; mitigation measures; spatial planning; groundwater; surface water; drinking water; risk assessment;

   Sammanfattning : The world’s drinking water sources are under growing pressure due to human activities, including infrastructure projects, agriculture, climate change, and the ever-increasing need for freshwater. Although there is a strong call to protect our source waters instead of increasing treatment efficiency at the drinking water treatment plant, the extent of protection measures is often hotly debated.

5. 14. Enhanced phosphorus removal from wastewater using virgin and modified slags : performance, speciation and mechanisms

   Författare :Minyu Zuo; Gunno Renman; Jon Petter Gustafsson; Lars Lövgren; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AOD; EAF; BFS; Calcium phosphate; XANES; slag mineralogy; Mark- och vattenteknik; Land and Water Resources Engineering;

   Sammanfattning : Argon oxygen decarburization slag (AOD) was tested in batch and column experiments to investigate its phosphorus (P) removal performance. The effects of factors such as AOD dose, initial P concentration of the feeding solution, and aging on the P removal ability of the slags were analyzed. LÄS MER

7. 15. Water management and performance on local and global scales : A comparison between two regions and their possibilities of knowledge transfer

   Författare :Nasik Najar; Sweden Stockholm Department of Land and Water Resources Engineering School of Architecture and the Built Environment Royal Institute of Technology (KTH); []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The problem to secure safe water supply, good sanitation and a good watercourse and marine environment status has become increasingly complex and at the same time more and more important to meet. It has been recognized, that an integrated approach must be used to meet not only technical and scientific aspects, but the role should also be included of factors such as economics, acceptability, capacity building, and efficient management in the overall view.
