  1. 6. Study on Process Performance and Evaluation of Dala Vatten’s Two Municipal Wastewater Treatment Plants.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Anjali Amatya; [2016]
    Nyckelord :Moving bed biofilm reactor; intermittent aeration; continuous aeration; Gagnef WWTP; Tällberg WWTP;

    Sammanfattning : Dala Vatten AB has been operating two municipal wastewater treatment plant namely Gagnef wastewater treatment plant and Tällberg wastewater treatment plant since 1970’s and 1950’s respectively in Dalarna, middle of Sweden. These both traditional treatment plants have been updated with continuous and intermittent aerated biological treatment facilities: Moving bed biofilm reactor (MBBR) in 2012 and 2007 respectively.

  3. 7. Evaluation of the suppressive effect of intermittent aeration on nitrite-oxidising bacteria in a mainstream nitritation-anammox process

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Amanda Okhravi; [2015]
    Nyckelord :Activity tests; anammox; AOB; Manammox; nitritation; NOB; OUR.; Aktivitetstester; anammox; AOB; Manammox; nitritation; NOB; OUR.;

    Sammanfattning : An alternative to conventional removal of nitrogen through autotrophic nitrification and heterotrophic denitrification is autotrophic nitritation-anammox. The anammox bacteria oxidise ammonium directly to nitrogen gas with nitrite as an electron acceptor. LÄS MER

  4. 8. Nitrous oxide emissions from deammonification process under different operation conditions.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Agnieszka Mazurek; [2015]
    Nyckelord :Anammox; Deammonification; Kaldnes; MBBR; Nitrous oxide;

    Sammanfattning : Wastewater treatment plays significant role in the environmental protection. The process has direct impact on quality of air and water. All treated sewage reaches fresh water reservoirs as well as gasses escaping from the process are emitted to the atmosphere. LÄS MER

  5. 9. Management of hydrogen sulfide in anaerobic digestion of enzyme pretreated marine macro-algae

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Salar Haghighatafshar; [2012]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Enzymatic pretreatment of algae – by means of cellulose degrading enzyme – was evaluated through lab-scale and pilot-scale experiments. The degradation efficiency of the enzyme depended on the initial physical quality of the algae. LÄS MER

  7. 10. Study on one-stage Partial Nitritation-Anammox process in Moving Bed Biofilm Reactors: a sustainable nitrogen removal.

    Master-uppsats, KTH/VA-teknik, Vatten, Avlopp och Avfall

    Författare :Andrea Bertino; [2011]
    Nyckelord :Anammox Biofilm; Deammonification; CANON; Moving Bed Biofilm Reactor; Re-ject water;

    Sammanfattning : In the last decade, several novel and cost-effective biological nitrogen removal technologies have been developed. The discovery of anaerobic ammonium oxidation (Anammox), about 15 years ago, has resulted in new opportunities for research and development of sustainable nitrogen removal systems. LÄS MER
