  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

  3. 2. Split flotation of calcite from wollastonite and microcline Jokkmokk calcite rich wollastonite ore

    Författare :Huang Fugen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

  4. 3. Atomistic simulation techniques for modelling inorganic/organic interface and flotation collector design

    Författare :Tarun Kundu; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : The choice of collector molecules in flotation process of mineral separation is invariably determined by tedious trial and error experimentation with inherent mounting expenditure. Here, we seek the help of atomistic simulation techniques, to help and judge the suitable collector molecule for selective mineral separation in flotation process, before actually conducting the experiment.

  5. 4. Reactive filter materials for ammonium and phosphorus sorption in small scale wastewater treatment

    Författare :Annelie Hedström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Existing small scale wastewater treatment systems in Nordic countries have generally low treatment efficiency regarding phosphorus and nitrogen. Even though only 15% of the Swedish population is connected to on-site wastewater treatment systems, the total discharge of phosphorus from these systems exceeds the total discharge from all municipal treatment plants in Sweden.

  7. 5. Atomistic simulation techniques for modelling inorganic/organic interface and flotation collector design

    Författare :Tarun Kundu; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : The choice of collector molecules in flotation process of mineral separation is invariably determined by tedious trial and error experimentation with inherent mounting expenditure. Here, we seek the help of computational solid chemistry techniques, namely the atomistic simulation techniques, to help and judge the suitable collector molecule for selective mineral separation in flotation process, before actually conducting the experiment.
