  1. 1. Pilot scale partial denitratation coupled anammox: an evaluation

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Tobias Ellingsen; [2022]
    Keywords : mainstream anammox; partial denitratation anammox; partial denitrification anammox; PDA; nitrite inhibition; anammox; water and environmental engineering; Technology and Engineering;

    Abstract : På avloppsreningsverk (ARV) som tillämpar kväverening är den vanligaste tekniken nitrifikation följt av denitrifikation. Denna process kräver omfattande luftning, vilket både är elintensivt och minskar mängden biogas som kan utvinnas. READ MORE

  3. 2. Controls of the partitioning of nitrate between DNRA and denitrifiers

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Frida Lindvall; [2022]
    Keywords : DNRA; denitrification; microcosm; experiment; arable soil;

    Abstract : In arable soils, the importance of denitrification, a respiratory process where nitrate (NO3-) is stepwisely reduced to nitrogen gas and nitrous oxide (N2O) is well established. More recently has dissimilatory nitrate reduction to ammonium (DNRA) gained interest as its importance in agricultural soils might have been largely overlooked. READ MORE

  4. 3. Nutrient Retention in Constructed Wetlands

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Johanna Kero; [2022]
    Keywords : Constructed wetlands; nutrient retention; phosphorus; nitrogen; catchment area factors; Anlagda våtmarker; näringsretention; fosfor; kväve; avrinningsområdesfaktorer;

    Abstract : Eutrophication, a surplus of nutrients, is a problem in aquatic environments and one of the Swedish Environmental Goals is that there should be no eutrophication caused by human activities. Constructed wetlands (CW:s) is a measure that could be implemented to decrease the transport of nutrients to water bodies through retention. READ MORE

  5. 4. Post-Denitrification on Sand Filter at Bromma Wastewater Treatment Plant

    University essay from KTH/Kemi

    Author : Emil Blocksjö; [2022]
    Keywords : Sand filter; Post-Denitrification; Nitrate; Nitrification; Wastewater; Sandfilter; Efterdenitrifikation; Nitrat; Nitrifikation; Avloppsvatten;

    Abstract : Examensarbetets syfte var att undersöka möjligheter till denitrifikation på sandfilter (SF) i industriell skala och hur det jämför sig med konventionella metoder för att uppnå denitrifikation och effekten av förändringen på processen vid Bromma reningsverk. Parametrar som undersöktes var rening av ammonium och nitrat, luftning, temperatur, pH, rening av fosfor, rening av organiskt material, rening av suspenderat material, förbigång av vatten vid SF och aktivslamanläggning (ASA), drifttider för SF:arna och total vattenbelastning på ASA och SF.

  6. 5. Nitrogen removal in MBBR : Investigating the effect of temperature

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Rediet Tezera Tafese; [2022]
    Keywords : Wastewater; Nitrogen removal; Nitrification; Denitrification; MBBR; Cold temperature; Avloppsvatten; Kväverening; Nitrifikation; Denitrifikation; MBBR; låg temperatur;

    Abstract : The project undertaken in this thesis was performed at MittSverige Vatten och Avfall (MSVA) in cooperation with the Swedish Environmental Research Institute (IVL). The effect of temperature on nitrogen removal using moving bed biofilm reactor (MBBR) was controlled using two separate lines by investigating the influence of temperature on nitrification, pre-denitrification, and post- denitrification in a pilot plant scale.
