3. 22. Microbial adhesion and surface modifications of sulphide minerals relevant to flotation and flocculation

   Författare :Annamaria Vilinska; Ponisseril Somasundaran; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

   Sammanfattning : Biological processes have been attracting attention in mineral processing industry due to their lower operating costs, environmental acceptability and flexibility in adaptation. Bio-hydrometallurgical methods to treat various sulphide and oxide ores have been developed during the years and these processes have been adopted by certain mineral industries. LÄS MER

4. 23. Coagulation process characteristics and pollutant removal from urban runoff

   Författare :Fredrik Nyström; Inga Herrmann; Annelie Hedström; Maria Viklander; Michael Cimbritz; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stormwater; urban snowmelt; road runoff; coagulation flocculation sedimentation; coagulation characteristics; coagulation mechanism; treatment efficiency; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

   Sammanfattning : Many different stormwater control measures (SCMs) can be implemented in order to mitigate issues with polluted stormwater flows into receiving water bodies.  The treatment function of  SCMs is commonly based on the removal of particles by sedimentation, thereby also removing pollutants associated with particles.

5. 24. Biological Treatment of Oily Sludge and Sediments

   Författare :Mait Kriipsalu; Chalmers tekniska högskola; []
   Nyckelord :bioremediation; refinery; aerobic biotreatment; flocculation-flotation unit FFU ; petroleum hydrocarbons; oily sludge; static biopile; PAHs; sediments;

   Sammanfattning : AbstractOily sludge, generated in refineries or in other industrial sectors, and oil-containing sediments, removed from water bodies during remediation works, pose an environmental problem. A common feature between both is their high water content, and variable content of organic and inorganic contaminants, which complicates their treatment. LÄS MER

7. 25. Modeling in Biomass Harvesting, Biomass Pyrolysis and Producer Gas Cleaning

   Författare :Ramiar Sadegh-Vaziri; Matthäus Bäbler; Alessio Frassoldati; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PBE modeling of flocculation; Pyrolysis in Rotary Kilns; Pellet Pyrolysis; Gas Cleaning; Desulfurization.; Chemical Engineering; Kemiteknik;

   Sammanfattning : Biomass is a viable alternative in order to mitigate the environmental effectscaused by the aggressive use of fossil feedstock during the last century.This thesis builds around the idea of a biofuel production process that iscomprised of biomass production, biomass gasication, gas cleaning andfuel production.
