1. 21. Nutrient management in sewerage systems : investigations of components and exergy analysis

   Författare :Daniel Hellström; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Sammanfattning : The aim of this thesis is to present results from different experiments dealing with components that may be useful to improve nutrient management within sewerage systems. Further, exergy analysis is used to compare the utilisation of physical resources within different alternatives for sewerage nutrient management. LÄS MER

3. 22. Anammox-based systems for nitrogen removal from mainstream municipal wastewater

   Författare :Andriy Malovanyy; Elzbieta Plaza; Adriano Joss; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater; Nitrogen removal; Ion exchange; Deammonification; Anammox; Mainstream; Mark- och vattenteknik; Land and Water Resources Engineering;

   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

4. 23. District Heating-driven Membrane Distillation for Water Purification in Industrial Applications

   Författare :Daniel Minilu Woldemariam; Andrew Martin; Massimo Santarelli; Wojciech Kujawski; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane Distillation; District Heating; Wastewater Purification; Heat demand; Technoeconomy; Membrandestillation; Fjärrvärme; Avloppsvattenrening; Värme-behov; Teknoekonomi; Energy Technology; Energiteknik;

   Sammanfattning : Domestic and industrial water demands are growing globally due to population growth and rapid economic development, placing increasing strains on water resources. Wastewater effluents generated from these and other activities impact the environment and are thus subject to tightening regulation. LÄS MER

5. 24. Application of indigenous materials in drinking water treatment

   Författare :Herbert Mpagi Kalibbala; Bengt Hultman; Joaquin Martinez; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coagulant aid; drinking water treatment; dual media filtration; Moringa oleifera; primary coagulant; trihalomethanes; volcanic ash; Water in nature and society; Vatten i natur och samhälle;

   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

7. 25. Moringa seed and pumice as alternative natural materials for drinking water treatment

   Författare :Kebreab Afwerki Ghebremichael; Bengt Hultman; Hallvard Ödegaard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; antimicrobial effects; coagulant protein; dual media filtration; ion exchange; Moringa oleifera; Miljöteknik; Environmental engineering; Miljöteknik;

   Sammanfattning : Pumice and the Moringa oleifera (MO) seed were investigated as alternative natural materials for drinking water treatment based on problems identified at the Stretta Vaudetto water treatment plant in Eritrea. Lab and pilot scale studies showed that pumice was a suitable alternative material for dual media filtration. LÄS MER
