1. 16. The deammonification in Moving Bed Biofilm Reactors

   Författare :Jingjing Yang; Elzbieta Plaza; Susanne Lackner; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Land and Water Resources Engineering; Mark- och vattenteknik;

   Sammanfattning : Deammonification process appears to be a good alternative to treat reject water. In this thesis, control strategies were studied at pilot scale in order to optimise the deammonification process operated in a Moving Bed Biofilm Reactor (MBBR) for reject water treatment. LÄS MER

3. 17. Optimisation of the slag formation in a blast furnace charged with 100% pellets

   Författare :Lena Sundqvist Ökvist; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Sammanfattning : This work is based on experiences from industrial blast furnaces. Process irregularities when testing self-fluxed pellets Process disturbances when charging increased proportions of coarse pellets Laboratory tests to evaluate the effect of basic fluxes on the slag formation in the bosh and in the raceway have been carried out.

4. 18. Treatment methods for the removal of per- and polyfluoroalkyl substances (PFASs) from drinking water : optimizing existing and exploring novel treatment techniques

   Författare :Vera Franke; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Worldwide, the demand for safe drinking water is rising. As drinking water sources are increasingly impacted by anthropogenic and environmental changes it is becoming a challenge to produce safe and clean water. LÄS MER

5. 19. Soil Remediation and Sustainable Development : Creating Appropriate Solutions for Marginalized Regions

   Författare :Henrik Haller; Anders Jonsson; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The scope of this doctoral thesis is appropriate soil remediation methods for marginalized regions that go beyond pollution reduction targets and include strategies to support sustainable development. Contaminated soil from industrial or agricultural activities poses potential health threats to animals and humans and also threatens economic systems by making land unsuitable for agriculture and other economic purposes.

7. 20. 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
