  1. 1. Greenhouse gas emissions and carbon burial in a small pond

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Maria Carlson; [2023]
    Keywords : Pond; greenhouse gas; carbon dioxide; methane; nitrous oxide; flux; ebullition; carbon burial; Damm; växthusgas; koldioxid; metan; lustgas; flöde; ebullition; kolbindning;

    Abstract : There are a lot of uncertainties when it comes to global greenhouse gas (GHG) emissions which affects society’s ability to effectively respond to climate change. Small ponds have been found to potentially play a large role in global warming. READ MORE

  3. 2. 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

  4. 3. Comparison of Different Wood Types for Use as a Porous Substrate in Denitrifying Woodchip Bioreactors

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Erica Erikson; [2021]
    Keywords : denitrification; woodchip bioreactor; column experiments; denitrifikation; träflis-bioreaktor; kolonnexperiment;

    Abstract : Explosives used in the mining industry release nitrate into the environment, causing concerns for the water quality in local river-systems. One way of reducing the nitrate loading into the environment is through a woodchip bioreactor. READ MORE

  5. 4. 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.

  6. 5. Alternativ till nitrittillsatser i charkuterivaror

    University essay from SLU/Department of Molecular Sciences

    Author : Julia Engsner; [2018]
    Keywords : nitrat; nitrit; alternativ till nitrittillsatser; charkuterivara; korv; skinka växtextrakt; grönsaks juice pulver; eteriska oljor; rosmarinextrakt; kitosan; lysosym; bacteriociner; nisin; natriumlaktat; high hydrostatic pressure;

    Abstract : Nitrit anses vara en multifunktionell tillsats som används i charkuterivaror. Den bi-drar med färg, smak, och verkar antioxidativt och antimikrobiellt. Till sin nackdel bidrar nitrit till bildandet av potentiellt cancerogena nitrosaminer vid intag eller under upphettning. Nitrit är därav en av de mer debatterade tillsatserna. READ MORE
