  1. 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 : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; 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.

  2. 2. Sustainable phosphorus removal in onsite wastewater treatment

    Author : David Eveborn; Jon Petter Gustafsson; Gunno Renman; Erik Kärrman; Paul Withers; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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

  3. 3. Microalgae for Phosphorus Removal from Wastewater in a Nordic Climate

    Author : Karin Larsdotter; Gunnel Dalhammar; Jörgen Hanaeus; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; assimilation; hydroponics; light; microalgae; nitrogen; phosphorus; plants; precipitation; wastewater treatment; Bioengineering; Bioteknik;

    Abstract : As part of a research project aiming to develop and evaluate a hydroponic system for wastewater treatment in Sweden, extended nutrient removal by microalgae was tested. The hydroponic/microalgal wastewater treatment system was built in a greenhouse in order to improve growth conditions for plants and algae. READ MORE

  4. 4. Extending Wastewater Treatment Process Models for Phosphorus Removal and Recovery : A Framework for Plant-Wide Modelling of Phosphorus, Sulfur and Iron

    Author : Kimberly Solon; Industriell elektroteknik och automation; []

    Abstract : As problems associated with shortage in resource supply arise, wastewater treatment plants turn to innovation to transform themselves into resource recovery facilities. Water groups worldwide recognize that wastewater treatment plants are no longer disposal facilities but rather sources of clean water, energy and nutrients. READ MORE

  5. 5. Microbial Phosphorus Removal in Waste Stabilisation Pond Wastewater Treatment Systems

    Author : Lydia Ambakisye Mbwele; Gunnel Dalhmmar; Ingrid Faye; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Wastewater treatment; waste stabilisation ponds; activated sludge; biological phosphorus removal; tropical climate; A.hydrophylla; Bioengineering; Bioteknik;

    Abstract : Waste Stabilisation Ponds (WSPs) are characterised by low phosphorus (P) removal capacity. Heterotrophic bacteria are principal microbial agents in WSPs in addition to algae. READ MORE
