  1. 1. Investigating organic fertilisers’ ability to mineralize during the first month of plant propagation

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Sebastan Farkas; [2023]
    Keywords : organic fertilizers; sustainability; mineralisation; nitrification;

    Abstract : There are many forms of organc fertilizers produced and sold in the EU, and it can be difficult to assess which ones are the best in regards of nutrient content and the rate of mineraliztion. Two separate trials were conducted to assess the mineralization rates of three different organic fertilizers, available for private customers, on the Swedish market. READ MORE

  3. 2. Separation and acidification of digested animal manure : properties of the future organic fertilizers

    University essay from SLU/Dept. of Soil and Environment

    Author : Marie Björs; [2023]
    Keywords : Digestate; Eutrophication; Farmers’ survey; Plasma activation; Screw press;

    Abstract : Agricultural areas with a high animal density contribute to eutrophication in waterbodies and seas worldwide due to accumulation of nutrients around animal farms. Animal manure is heavy and bulky, thus unpractical to transport long distances and new techniques have been developed to refine animal manure and make it easier to transport. READ MORE

  4. 3. Evaluation of Carbon Source Addition on Denitrification Efficiency : A study in a continuous biological leachate water treatment system.

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Isac Ingfeldt; [2020]
    Keywords : denitrification; nitrification; WWTP; carbon source; ethanol; glycerol; Brenntaplus VP1; nitrate; pilot;

    Abstract : In 2014 SÖRAB constructed a continuous biological treatment system (KBR) to handle leachate waterfrom the landfill at the facility in Löt, north of Stockholm. The KBR is mainly focused on removal ofammonium nitrogen which would otherwise be released in to the recipient and contribute toeutrophication and damage to the environment. READ MORE

  5. 4. Using bioaugmentation to enhance the denitrification process in a treatment plant for landfill leachate

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Oscar Skirfors; [2020]
    Keywords : Bioaugmentation; Landfill leachate; Wastewater treatment; Biological nitrogen removal; Denitrification; Waste management; Bioaugmentation; Deponilakvatten; Vattenrening; Biologisk kväverening; Denitrification; Avfallshantering;

    Abstract : It has been illegal to deposit household waste in Swedish landfills since 2005. The large amount of waste deposited prior to this does however continue to pose an environmental concern, mainly in the form of leachate water. This study focused on enhancing the denitrification process in a leachate water treatment plant through bioaugmentation. READ MORE

  6. 5. Partial denitrification as nitrite provider for mainstream anammox

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Felix Wallin Holmin; [2020]
    Keywords : Water engineering; Environmental engineering; Mainstream anammox; Partial denitrification; PDA; MBBR; Nitrogen removal; Vattenförsörjningsteknik; Avloppsteknik; Technology and Engineering;

    Abstract : In traditional wastewater treatment, nitrogen is removed through the biological process combination of nitrification and denitrification. Although it is a well-established method, the need for aeration and possible addition of an external carbon source results in it being an energy-negative and costly process, thus making alternative methods for nitrogen removal compelling to examine.
