1. 1. Improvement of Wastewater Sludge Digestion

   Författare :Michael Recktenwald; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anaerobic digestion; biogas; cation-binding agents; enzymes; enzymatic activity; extracellular polymeric substances EPS ; industrial scale trials; methanization; municipal sewage; sludge treatment; wastewater treatment plant;

   Sammanfattning : The reduction of sludge volumes for disposal is a topic of high interest for wastewater treatment plants (WWTP) all over the world. Steadily increasing volumes for disposal create an economic, environmental, legislative and technological challenge. LÄS MER

3. 2. Ozonation as sewage effluent treatment : toxicological effects in adult and embryonic zebrafish, Danio rerio

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

   Sammanfattning : Pharmaceutical residues are not efficiently removed by current sewage treatment plant (STP) technologies. This allows for the release of pharmaceutical residues into the aquatic environment. Pharmaceuticals and their metabolites are problematic because they are designed to affect biological processes in non-target aquatic species. LÄS MER

4. 3. Use and Development of Diffusive Samplers to Analyse the Fate of Polycyclic Aromatic Compounds, Polychlorinated Biphenyls and Pharmaceuticals in Wastewater Treatment Processes

   Författare :Lijana Augulyte; Patrik L. Andersson; Anna Ledin; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioavailable; biologically activated carbon; PRCs; sampling rate; SPMD; sorption; wastewater treatment; diffusive passive samplers; human pharmaceuticals; municipal sewage treatment plant; organic micropollutants; polycyclic aromatic compounds; PAHs; PCBs; POCIS; Environmental chemistry; Miljökemi;

   Sammanfattning : The efficiency of wastewater treatment systems is commonly measured by the reductions of parameters such as biological oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solids (TSS) and/or reductions in levels of selected macro compounds (e.g. long-chained hydrocarbons and inorganic compounds).

5. 4. Resource recovery from wastewater treatment: challenges, opportunities and guidance for planning and implementation

   Författare :Mariana Cardoso Chrispim; Miklas Scholz; Marcelo Antunes Nolasco; Jennifer R. McConville; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular economy; Resource recovery; Sewage; Planning; Water; Nutrient; Biogas; Developing countries; Urban areas;

   Sammanfattning : Considering the current resources scarcity, Wastewater Treatment Plants (WWTP) should be adapted to become more sustainable. For example, it is possible to recover resources present in municipal wastewater. LÄS MER

7. 5. Enhanced biogas production from municipal WWTPs : Co-digestion of microalgae with sewage sludge and thermophilic secondary digestion of mesophilic digested sludge

   Författare :Jesper Olsson; Eva Thorin; Emma Nehrenheim; Raúl Muñoz Torre; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Biogas is produced when organic material is broken down in oxygen-free (anaerobic) conditions. This process is called anaerobic digestion and is used in most large and medium-sized municipal wastewater treatment plants in Sweden. LÄS MER
