2. 1. Physicochemical Treatment of Municipal Wastewater : From Direct Membrane Filtration to Adsorption of Organic Micropollutants

   Author : Simon Gidstedt; Avdelningen för kemiteknik; []
   Keywords : 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;

   Abstract : 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.

4. 2. Going Beyond the Desktop Computer with an Attitude

   Author : Tomas Sokoler; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human Computer Interaction; Interaction Design; Interface Design; Ubiquitous Computing; Augmented Reality;

   Abstract : This dissertation is based upon the work within a number of research projects, five of which are presented in detail. The work follows the direction of research laid out by the Ubiquitous Computing and Augmented Reality research programs and concerns the broad question of where to go as we seek to take digital technology, and human interactions with this technology, beyond the traditional desktop computer.

5. 3. Small Sanitation Systems – Treatment Efficiency, Sustainability and Implementation

   Author : Brenda Vidal; Annelie Hedström; Inga Herrmann; Günther Langergraber; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable sanitation; sand filter; phosphorus filter; package plant; cold climate; treatment process; system analysis; sustainability indicators; decentralization; centralization; historical development; on-site; resource recovery; source separation; source-separating systems; blackwater; urine; greywater; hållbarthetsanalys; små avlopp system; enskilda avlopp; markbädd; minireningsverk; kallt klimat; systemanalys; fosforfälla; fosforfilter; indikator; urin sortering; svartvatten; toalettvatten; gråvatten; BDT; VA-teknik; Urban Water Engineering;

   Abstract : Current socio-technical wastewater system paradigms are being challenged by emerging global issues such as climate change, environmental degradation and scarcity of resources. Thus, exploration of innovative new urban water management solutions is required that enable closure of resource loops. READ MORE

6. 4. Substance flow analyses of metals and organic compounds in an urban environment : – the Stockholm example

   Author : Nina Månsson; Bo Bergbäck; Stefan Anderberg; Högskolan i Kalmar; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Miljövetenskap; Environmental Science;

   Abstract : The intensified use of materials, products and goods in our time involves massive consumption of metals and organic compounds that can be released from society to the environment in the various stages of production, use and waste. Depending on the circumstances this may give rise to environmental risks, as metals in general and certain organic substances may be toxic in the short or long term. READ MORE

7. 5. Persistent Organic Pollutants and the Environment : A Chemometric Approach to the Study of Halogenated Aromatics

   Author : Tomas Öberg; Bo Bergbäck; Bo Wiman; Jaakko Paasivirta; Högskolan i Kalmar; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Environmental Chemistry; Miljökemi;

   Abstract : Concern is growing about the environmental and health effects of persistent organic pollutants (POPs), many of which are halogenated aromatic compunds. The research reported in this thesis focuses on factors determining their behaviour and release into the environment. READ MORE
