  1. 1. Phosphorus recycling from wastewater to agriculture using reactive filter media

    Författare :Victor Cucarella Cabañas; Gunno Renman; Dan Berggren Kleja; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Filtra P; phosphorus; Polonite; recycling; sorption; wollastonite; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : This thesis focused on testing the suitability of reactive filter media used for phosphorus (P) removal from wastewater as fertilizers, thus recycling P to agriculture. The work compared the P sorption capacity of several materials in order to assess their suitability as a source of P for plants. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Onsite wastewater treatment; Soil treatment system; Phosphorus; Removal mechanisms; Environmental impacts; Life cycle assessment;

    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

  5. 4. Phosphorus removal in reactive filter materials : factors affecting the sorption capacity

    Författare :Charlotte Nilsson; Gunno Renman; Lena Johansson Westholm; Aleksandra Drizo; Annelie Hedström; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Phosphorus is an essential component in all living organisms; it is one of the components of the DNA and the key element in the energy supplying molecule adenosine triphosphate (ATP). Throughout the history, humans have been recycling phosphorus to agriculture; thereby increasing the yield, examples of this includes the burning of plants and the use of manure. LÄS MER

  7. 5. Fortification of soil-based wastewater treatment systems with versatile ubiquitous reactive media for enhanced removal of phosphorus and other pollutants

    Författare :Ezekiel Kholoma; Gunno Renman; Agnieszka Renman; Haniso Motlhabane; Mark Healy; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biochar; Fortified filter; Gas concrete; Phosphorus removal; Reactive filter media; Wastewater treatment; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : Concerns about potential risks posed by discharge from small-scale wastewater treatment (SWT) systems to receiving water bodies have prompted robust enforcement of national discharge quality standards in rural areas of most developed countries. Consequently, communities in such places are in need of effective technologies with which to achieve compliance. LÄS MER
