1. 21. Enhancement of Volatile Fatty Acid Production from Dairy Wastewater

   Författare :Merve Atasoy; Zeynep Cetecioglu; Juan Lema; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Volatile fatty acid; mixed culture fermentation; pure culture; bioaugmentation; bacterial community; Flyktiga fettsyror; jäsning med blandkultur; renkultur; bioaugmentering; bakteriesamhälle; Chemical Engineering; Kemiteknik;

   Sammanfattning : Resource recovery from waste-streams is a highly promising approach to meet with urbanization and modernization consequences. Rapid human population growth, expanding industrialization and excessive consumption of resources lead to increasing demand for raw materials and energy sources, and an escalation of greenhouse gas emission.

3. 22. Treatment of Wastewater Generated by Wood-based Dry Industries : Advances Oxidation Processes & Electrocoagulation

   Författare :Henrik Hansson; William Hogland; Marcia Marques; Ollie Dahl; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Advanced oxidation processes; Electrocoagulation; Fenton; Industrial storm-water; Ozone; Respirometry assays; Wastewater; Wood floor industry.; Environmental Chemistry; Miljökemi;

   Sammanfattning : Wood is a material with an enormous number of applications. For decades, the development of wastewater treatment technologies tailored for the wood sector has focused on those industries that have water as an integral part of the industrial production, such as paper and pulp.

4. 23. 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.

5. 24. Recovery of organic carbon from municipal waste streams

   Författare :Isaac Owusu-Agyeman; Elzbieta Plaza; Zeynep Cetecioglu; Irini Angelidaki; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Volatile fatty acid; Anaerobic granules; Co-digestion; Municipal waste; Chemical Engineering; Kemiteknik;

   Sammanfattning : The focus of the current study was on the recovery of carbon from municipal bio-waste streams. Firstly, the relationship between methanogenic pathways and the properties of anaerobic granules was studied using two pilot-scale upflow anaerobic sludge blanket (UASB) reactors with different granule size distribution.
