  1. 1. Partial denitrification as nitrite provider for mainstream anammox

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Felix Wallin Holmin; [2020]
    Nyckelord :Water engineering; Environmental engineering; Mainstream anammox; Partial denitrification; PDA; MBBR; Nitrogen removal; Vattenförsörjningsteknik; Avloppsteknik; Technology and Engineering;

    Sammanfattning : 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.

  3. 2. Pilot-scale plant application of membrane aerated biofilm reactor (MABR) technology in wastewater treatment

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Qianqian Li; [2018]
    Nyckelord :Membrane aerated biofilm reactor; municipal wastewater treatment; nitrogen removal; SND-MBR; Zeelung; Membranbelukt biofilmreaktor; kommunal avloppsrening; kväveavlägsnande; SNDMBR; Zeelung;

    Sammanfattning : This membrane aerated biofilm reactor (MABR) pilot project was performed at Ekeby wastewater treatment plant (WWTP) in Eskilstuna, Sweden. This plant is facing a future challenge of effluent TN < 10mg/L according to the new standard and the growing population, where higher treatment capacity is needed. LÄS MER

  4. 3. Möjligheten att kombinera pulveriserat aktivt kol (PAK) och MBBR för avskiljning av organiska mikroföroreningar

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sofia Högstrand; Maja Ignell; [2018]
    Nyckelord :PAK; pulveriserat aktivt kol; MBBR; Moving Bed Biofilm Reactor; avancerad rening; avloppsreningsverk; organiska mikroföroreningar; avloppsteknik; Technology and Engineering;

    Sammanfattning : The increased use of pharmaceuticals in combination with inadequate techniques and procedures in the wastewater treatment plants (WWTPs) have resulted in higher concentrations of pharmaceuticals and other organic micro pollutants (OMPs) in the aquatic environment. It has been established that these pollutants have caused changes in the behaviour and reproduction of fishes. LÄS MER

  5. 4. Challenges during start-up of urine nitrification in an MBBR

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Ellen Ascard Edefell; [2017]
    Nyckelord :Urine; source-separation; urine stabilisation; nitrogen recovery; nitrification; moving bed biofilm reactor; MBBR; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

    Sammanfattning : Nitrogen and phosphorous compounds are secreted by humans and treated in wastewater treatments plants. These substances are also found in agricultural fertilisers and needed for plant growth. Nutrient recycling is limited in conventional treatment systems and valuable products are lost. LÄS MER

  7. 5. Älgarås avloppsreningsverk- studie och metodisk felsökning av en biobädds BOD-rening

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Amanda Haglind; [2015]
    Nyckelord :Biobädd; biologisk rening; BOD; avloppsrening; metodisk felsökning;

    Sammanfattning : Wastewater contains biodegradable materials, which are often measured as BOD7. Trickling filters are sometimes used as a purification step for BOD-reduction. A trickling filter is a tower, which is filled with a carrier material. Microorganisms grow on the carrier material in the form of a biofilm. LÄS MER
