  1. 1. Mainstream Deammonification process monitoring by bacterial activity tests

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Andrea Carranza Muñoz; [2020]
    Keywords : Ammonia Oxidizing Bacteria AOB ; Anammox; Bacterial activity; Deammonification; Heterotrophic bacteria; IFAS; Mainstream wastewater; Nitrite Oxidizing Bacteria NOB ; Nitrogen Removal.;

    Abstract : Deammonification is a widely used technology for side stream treatment with rich ammonium streams at relatively high temperatures, such as, the reject water coming from dewatering units in treatment of digested sludge and industrial wastewaters. The deammonification process has lower operational costs than conventional systems, consumes less energy, enables the increase of biogas production and it is easy to implement. READ MORE

  3. 2. Evaluation of the effect of different SCOD/TN ratios in a mainstream nitritation process

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Doaa el Halabi; [2017]
    Keywords : Partial nitrification; nitritation; microscreen; filtration; Chemical oxygen demand; moving bed biofilm reactor; Partial nitrification anammox; PNA.; Technology and Engineering;

    Abstract : Avloppsvatten är rikt på organiskt material, det organiska materialet har med fördel använts för biogasproduktion. Den traditionella kvävereningsprocessen kräver organiskt material, därför har ett extern organiskt material använts. READ MORE

  4. 3. Assay of nitrification potentials in sewage sludge : development and evaluation of method, and nitrification potentials in sewage sludge before and after application to soil

    University essay from SLU/Dept. of Microbiology

    Author : Caroline Jöngren; [2016]
    Keywords : Sewage sludge; nitrification potentials; PAO; sanitations treatment; ammonium; storage treatments; nitrous oxide; Nitobacteriacea; Nitrosomona;

    Abstract : Sewage sludge (SS) contains valuable plant nutrients applicable to soil as fertilizer. Application to arable land is though controversial as SS can contain contains such as human pathogens, heavy metals and xenobiotics. READ MORE

  5. 4. Evaluation of nitrite oxidizing bacteria (NOB) activity in the nitritation reactor of a two-stage partial nitritation-anammox (PNA) system operating at mainstream conditions

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Emine Gülce Hepdarcan; [2016]
    Keywords : MBBR; Nitrogen removal; Partial Nitritation-Anammox; Wastewater treatment; Z-200 carriers; AOB; NOB; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering; Earth and Environmental Sciences;

    Abstract : Nitrification-denitrification process, which is the most commonly used method for nitrogen removal from wastewaters, is energy demanding and contributes very much to the the carbon footprint of wastewater treatment. One of the alternative methods for nitrogen removal is the nitritation-anammox process. READ MORE

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

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

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

    Abstract : 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. READ MORE
