  2. 21. Metal sorption to ferrihydrite : phosphate effects, X-ray absorption spectroscopy and surface complexation modelling

    Author : Charlotta Tiberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Phosphorus affects the sorption of many metals and arsenate to iron (hydr)oxides. This may influence the mobility and bioavailability of metals and arsenate. Phosphorus therefore plays an important role in, e.g. READ MORE

  4. 22. Analysis of the impact of anthropogenic pollution on shallow groundwater in peri-urban Kampala

    Author : Robinah Kulabako; Roger Thunvik; Mai Nalubega; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shallow groundwater; Sanitation; Peri-urban; Vadose zone; Anthropogenic; Modelling; Environmental engineering; Miljöteknik;

    Abstract : An investigation to assess the anthropogenic pollutant loads, transport and impact on shallow groundwater in one of Kampala’s peri-urban areas (Bwaise III Parish) was undertaken. Bwaise III is a densely populated informal settlement with a high water table (... READ MORE

  5. 23. Filtration System For On-Site Wastewater Treatment : Experiences From Modelling and Experimental Investigations

    Author : Rajabu Hamisi; Gunno Renman; Anders Wörman; Scholz Miklas; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : Many on-site wastewater treatment systems in Sweden are not sustainable in terms of treatment efficiency, nutrient recycling and economics. Achieving reliable and sustainable systems to meet on-site wastewater treatment demands requires comprehensive field investigations of the performance of novel technologies. READ MORE

  6. 24. On Distribution Coefficients in Aquatic Systems

    Author : Håkan Johansson; Bert Allard; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Distribution coefficient; lake; modelling; morphometry; stream; Geovetenskap; Earth sciences; Geovetenskap; Geovetenskap med inriktning mot miljöanalys; Earth Science with specialization in Environmental Analysis;

    Abstract : In this thesis, different types of chemical and physical distribution coefficients are identified, examined and used to describe the fate and transport pathways of substances in aquatic systems.Observations from field experiments in streams with non-reactive and reactive tracers constituted the basis for development of an advection-dispersion model.

  7. 25. Biofiltration technologies for stormwater quality treatment

    Author : Godecke-Tobias Blecken; Jean-Luc Bertrand-Krajewski; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Due to high runoff volumes and peak flows, and significant contamination with (inter alia) sediment, metals, nutrients, polycyclic aromatic hydrocarbons and salt, urban stormwater is a major cause of degradation of urban water ways. Since current urban drainage systems, which heavily rely on piped sewer networks, may not be sustainable, attempts are being made to develop and refine sustainable urban drainage solutions, notably in Water Sensitive Urban Design (WSUD) and Low Impact Development (LID) concepts.
