  1. 11. 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

  3. 12. Mapping spontaneous biological phosphorus removal in a membrane bioreactor process without the anaerobic condition : Investigating the effect of alternative external carbon sources

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ross Roberts; [2020]
    Keywords : enhanced biological phosphorus removal; PAO; anoxic; carbon source; ethanol; ORP;

    Abstract : Phosphorus removal in wastewater treatment is commonly achieved by chemical precipitation, enhanced biological phosphorus removal (EBPR) or a simultaneous combination of the two. A defined anaerobic condition is widely regarded as the critical element to sustain EBPR. However, this study demonstrates that EBPR is indeed occurring in a 4. READ MORE

  4. 13. Considerations for the Establishment of an Anaerobic Biofilm in an AnMBBR

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Emma Månsson; [2020]
    Keywords : Anaerobic; MBBR; biofilm; carrier; methane; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : Behandling av avloppsvatten för att avlägsna ämnen som kan ha en negativ påverkan på den mänskliga hälsan och naturen är mycket viktigt innan vattnet återanvänds eller släpps ut i naturen. Intresset för anaerob vattenrening har ökat eftersom det är ett bra komplement till aeroba processer, samt för att det producerar energi i form av metangas. READ MORE

  5. 14. Chemical Stabilization of Arsenic in Contaminated Soil under Low Redox Conditions

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Eva Smedborn Pausson; [2019]
    Keywords : ;

    Abstract : Remediation techniques for arsenic contaminated soil have previously focused mostly on the surface soil layers where aerobic conditions are prevalent. In this master thesis, chemical stabilization by adding zero-valent iron (Fe(0)) and calcium oxide (CaO) to an arsenic-contaminated soil under low redox conditions have been studied through up-flow percolation tests.

  6. 15. Physiological adaptive mechanism to oxidative stress in Lactobacillus reuteri DSM 17938

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Julian David Rivera Ramirez; [2019]
    Keywords : Applied microbiology; Teknisk mikrobiologi; Biology and Life Sciences; Chemistry;

    Abstract : Probiotics are living microorganisms which could induce a potential health benefit to the host when consumed in adequate amounts. Among the different probiotics in the market, Lactobacillus reuteri strain DSM 17938 is a microaerophilic and heterofermentative organism that is able to tolerate high oxygen conditions compared with another L.
