2. 1. Bed filters for phosphorus removal in on-site wastewater treatment : Removal mechanisms and sustainability

   Author : David Eveborn; Jon Petter Gustafsson; Gunno Renman; Erik Kärrman; Lars Lövgren; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; On-site wastewater treatment; Eutrophication; Environmental impact assessment; Phosphorus removal mechanisms; Soil infiltration; Reactive bed filters; Environmental engineering; Miljöteknik; Water engineering; Vattenteknik; Soil chemistry; Markkemi;

   Abstract : For many surface waters, phosphorus (P) leaching is a serious problem that should be minimized to prevent eutrophication. In Sweden there is a demand for physical and technical development of high-performance P removal techniques to reduce phosphorus leaching from on-site wastewater treatment systems to the Baltic Sea.

4. 2. Sustainable phosphorus removal in onsite wastewater treatment

   Author : David Eveborn; Jon Petter Gustafsson; Gunno Renman; Erik Kärrman; Paul Withers; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Onsite wastewater treatment; Soil treatment system; Phosphorus; Removal mechanisms; Environmental impacts; Life cycle assessment;

   Abstract : Aquatic eutrophication is a serious environmental problem that occurs all over the world. To protect surface waters (in particular the Baltic Sea), the regulatory pressure on onsite wastewater treatment (OWT) systems have increased in Sweden. READ MORE

5. 3. Biotic Ligand model : A tool for risk assessment of metals in Scandinavian fresh waters?

   Author : Sabina Hoppe; Magnus Breitholtz; Jon-Petter Gustafsson; Karel De Schamphelaere; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; BLM; Soft freshwaters; Sweden; Cu; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Products from iron and copper mining are among Sweden’s top exports. However, as the metals are excavated, they often end up in the aquatic environment where they can cause toxicity. READ MORE

6. 4. Environmental assessment of municipal solid waste incinerator bottom ash in road constructions

   Author : Susanna Olsson; Jon Petter Gustafsson; Dan Berggren; Erik Kärrman; Bo Bergbäck; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; bottom ash; environmental impact; LCA; waste management; leaching; copper; dissolved organic carbon; Environmental chemistry; Miljökemi;

   Abstract : There are several incentives for using bottom ash from municipal solid waste incineration (MSWI bottom ash) as a construction material, such as for road construction. These incentives include decreased disposal of material on landfills and a reduced amount of raw material extracted for road building purposes. READ MORE

7. 5. Iron and aluminium speciation in Swedish freshwaters : Implications for geochemical modelling

   Author : Carin Sjöstedt; Jon Petter Gustafsson; Peggy O'Day; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geochemical equilibrium modelling; pH; adsorption to ferrihydrite; metal-NOM complexation; liming; EXAFS spectroscopy;

   Abstract : Speciation governs transport and toxicity of trace metals and is important to monitor in natural waters. Geochemical models that predict speciation are valuable tools for monitoring. They can be used for risk assessments and future scenarios such as termination of liming. READ MORE
