    Author : SUSANNE BERGSTRAND; [2020]
    Keywords : ;

    Abstract : source of thermal energy. Wastewater as a source of energy has gotten more attention in recent times, as the Sustainable Development Goals in combination with local challenges encourage new technical solutions that can replace old and outdated technology. READ MORE

  3. 2. 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

  4. 3. Volatile fatty acid production from co-fermentation of primary sludge and food waste without pH control

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Binyam Bedaso; [2019]
    Keywords : Volatile fatty acid; Co-fermentation; Primary sludge; Food waste;

    Abstract : The production of volatile fatty acids (VFAs) from waste stream is gaining high attention because of their high market value and wide range of applications. In this study, the production of VFA from co-fermentation of primary sludge from wastewater treatment plant and food waste without pH control was evaluated using a pilot-scale reactor in a semi-continuous mode of operation.

    Abstract : Between 2007-2014, as part of the Greppa Näringen, there was a subproject on phosphorus losses called Focus on Phosphorus (FoP; Greppa Fosforn). Previous measures on eutrophication mainly focused on nitrogen leakage, whilst the purpose of FoP was to test already known mitigation methods against phosphorus losses in the field. READ MORE
