2. 6. 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

4. 7. Suspended solids and metals in highway runoff : implications for treatment systems

   Author : Magnus Hallberg; Gunno Renman; Thomas Pettersson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik;

   Abstract : It is known that traffic is a source of pollutants and that pollutant loads increase with elevated traffic densities. Studies executed in Stockholm, Sweden advocate that highway runoff from roads with an annual average daily traffic (AADT) exceeding 30,000 vehicles need treatment before discharge to the receiving water.

5. 8. Treatment conditions for the removal of contaminants from road runoff

   Author : Magnus Hallberg; Gunno Renman; Jiri Marsalek; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dissolved matter; filter bed; particulate matter; sedimentation; suspended solids; Environmental engineering; Miljöteknik;

   Abstract : The pollutant load in road runoff is related to traffic densities and road maintenance activities. Inurbanised areas treatment of road runoff is common and often considered necessary. The pollutantsare partitioned between the particulate and dissolved matter. However, the contaminantstend to have an affinity to the particulate material. READ MORE

6. 9. 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

7. 10. Modelling phosphorus dynamics in constructed wetlands upgraded with reactive filter media

   Author : Rajabu Hamisi; Gunno Renman; Berit Balfors; Roger Thunvik; Steve W. Lyon; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Constructed Wetland; COMSOL; Modelling; Reactive Solute Transport; Sorption Process; Mark- och vattenteknik; Land and Water Resources Engineering;

   Abstract : Developing low-cost and effective technologies to upgrade phosphorus (P) removal from the catchment runoffs and rural wastewater treatment facilities is one of the main research agendas to save the Baltic Sea from eutrophication. In Sweden, the construction of the constructed wetlands has been one of the environmental objectives for wastewater quality improvement in the small communities. READ MORE
