1. 21. Methodology for evaluation of hazards from solid waste and landfill generated leachate

   Författare :Britt-Marie Svensson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; leaching test; waste acceptance criteria.; leachate treatment; landfill leachate; toxicity test; Analytical protocol; organic pollutants;

   Sammanfattning : A methodology based on an analytical protocol for evaluation of hazards from landfill leachate and solid waste is described. A dynamic analytical protocol, the LAQUA protocol, including measurements of inorganic and water-quality parameters, polar and non-polar organic marker compounds, and toxicity, was constructed.

3. 22. Methodology for evaluation of hazards from solid waste and landfill-generated leachate

   Författare :Britt-Marie Svensson; Lennart Mathiasson; Lennart Mårtensson; Ann-Sofi Rehnstam-Holm; Kristianstad University; []
   Nyckelord :;

   Sammanfattning : Avfall har alltid uppkommit i alla samhällen i alla tider. Det vanligaste sättet att hand om det har varit att samla avfallet i soptippar (deponier) på mark som ansetts obrukbar, t.ex. i sankmarker utanför bebyggelsen. LÄS MER

4. 23. Physicochemical Treatment of Municipal Wastewater : From Direct Membrane Filtration to Adsorption of Organic Micropollutants

   Författare :Simon Gidstedt; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Direkt membranfiltrering; Granulärt aktivt kol; Avloppsvatten; Kemisk förbehandling; Mikrosilning; Direct membrane filtration; Granular activated carbon; Wastewater; Chemically enhanced primary treatment; Microsieving;

   Sammanfattning : Pharmaceutical residues and other organic micropollutants are transported via municipal wastewater to wastewater treatment plants (WWTPs). However, current treatment processes are not designed to remove organic micropollutants, and several such compounds have been found in recipients, where they can have negative effects on aquatic organisms.

5. 24. Proposing Combined Approaches to Remove ECG Artifacts from Surface EMG Signals

   Författare :Sara Abbaspour; Maria Lindén; Urban Wiklund; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Electromyography (EMG) is a tool routinely used for a variety of applications in a very large breadth of disciplines. However, this signal is inevitably contaminated by various artifacts originated from different sources. LÄS MER

7. 25. A Study of Biomass Combustion Problems and the Selective Catalytic Oxidation of Ammonia

   Författare :Göran Olofsson; Kemiska institutionen; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Energy research; Reaction mechanism; Ammonia degradation; Pt CuO Al2O3 Catalysts; SCO; Selective Catalytic Oxidation; Catalytic hot gas cleaning; Bed agglomeration; NOx emissions; Fluidised bed; Biomass combustion; Biogas; Energiforskning;

   Sammanfattning : Increasing awareness of the need of reducing CO2, NOx and SOx emissions from combustion systems has led to a strong interest in biomass as a fuel source. Using it in combination with fluidised bed combustion technology can lead to a lowering of NOx emissions to the atmosphere. LÄS MER
