  1. 6. Anammox in IFAS reactor for reject water treatment

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Bingquan Chen; [2019]
    Keywords : Deammonification; IFAS; Online sensors; Partial nitritation Anammox; Reject water; Specific anammox activity;

    Abstract : The aim of this study was to evaluate the performance of the integrated fixed-film activated sludge (IFAS) reactor achieving partial nitritation/anammox process to treat reject water after dewatering of digested sludge. During the study period, dissolved oxygen setpoint, aeration mode and inflow loading were changed to evaluate their influence on the process performance and efficiency in the reactor. READ MORE

  3. 7. In-situ Reduction by Incorporating H2 Filled Hollow Glass Microspheres in PM HIP Capsules

    University essay from KTH/Materialvetenskap

    Author : Emil Strand; [2018]
    Keywords : Hot isostatic pressing; hollow glass microspheres; powder metallurgy; oxide reduction; surface oxides; hydrogen;

    Abstract : For many metal components the presence of hard, non-metallic inclusions such as oxides lowers the impact toughness by acting as fracture initiation points and easing crack propagation. In components produced by powder metallurgy hot isostatic pressing (PM HIP), oxides often form a continuous network of small, spherical inclusions after consolidation at the prior particle boundaries (PPB).

  4. 8. Nitrogen removal from municipal wastewater by mainstream Partial Nitritation/Anammox process

    University essay from KTH/Vatten- och miljöteknik

    Author : Alessio Robiglio; [2018]
    Keywords : Mainstream; Deammonification; IFAS; UASB; Anammox; Anoxia; Aeration; Online; Monitoring; Inhibition; Wastewater;

    Abstract : Mainstream Partial Nitritation/Anammox, also known as Mainstream Deammonification, is a promising technology for future wastewater purification that aims to remove nitrogen from wastewater in order to prevent the eutrophication. It is less costly than the traditional nitrification/denitrification process and it heads towards the direction of converting the WWTPs from energy consuming into energy producing facilities.

  5. 9. Cloning, expression and production of Vicia faba Leghemoglobin B

    University essay from Lunds universitet/Tillämpad biokemi

    Author : Gustav Lindéus; [2016]
    Keywords : blood substitute; fermentation; gene technology; Leghemoglobin; hemoglobin; Vicia faba; applied biochemistry; tillämpad biokemi; Biology and Life Sciences;

    Abstract : In this thesis a preliminary evaluation of the potential of a leghemoglobin (Lb) for the development of a blood substitute in humans, resembling hemoglobin (Hb) in red blood cells, was conducted. Leghemoglobin B (VfLbB), a gene from Vicia faba, was cloned into a pET-DEST42 vector, using the Gateway™ recombination technology. READ MORE

  6. 10. 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
