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

2. Sustainable phosphorus removal in onsite wastewater treatment
Sammanfattning : 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. LÄS MER
3. Biotic Ligand model : A tool for risk assessment of metals in Scandinavian fresh waters?
Sammanfattning : 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. LÄS MER
4. Environmental assessment of municipal solid waste incinerator bottom ash in road constructions
Sammanfattning : 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. LÄS MER
5. Iron and aluminium speciation in Swedish freshwaters : Implications for geochemical modelling
Sammanfattning : 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. LÄS MER
