  1. 11. 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.

  3. 12. Suitable treatment of source separated greywater for discharge into an Urban Environment

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Evalyne Cathy Arinaitwe; [2018]
    Keywords : water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Abstract : It can no longer be refuted that greywater reuse is paramount to curbing the persistent global water crisis. Of the domestic wastewaters, greywater is less polluted than blackwater, but treatment is still necessary to make it safe for reuse. The most common greywater reuse application is toilet flushing.

  4. 13. Modification of a Moving Bed Biofilm Reactor(MBBR) due to radically changed process conditions : A case study of Kvarnsveden paper mill

    University essay from Högskolan Dalarna/Energiteknik

    Author : Liv May Johansson Macedo; [2018]
    Keywords : Moving Bed Biofilm Reactor; Pulp and Paper Wastewater; Performance Evaluation; Energy Efficient.;

    Abstract : Papermaking process require large amounts of energy and water; therefore, pulp and paper mills can be potentially very polluting. The wastewater resulting from the papermaking process must be carefully managed as it is very rich in dissolved organic matter and contain compounds that make it difficult to treat. READ MORE

  5. 14. Deammonification efficiency in combined UASB and IFAS system for mainstream WWT

    University essay from KTH/Mark- och vattenteknik

    Author : Noureddine Khayi; [2017]
    Keywords : Ammonium; Nitrite; Nitrate; Deammonification; UASB; MBBR; DO; Aeration; monitoring; on-line control;

    Abstract : The study is about Nitrogen removal from the low concentrated mainstream wastewater after Upflow Anaerobic Sludge Blanket reactor process (UASB) by single-stage Partial Nitritation/Anammox process in a pilot scale reactor at Hammarby Sjöstad in Stockholm. A mixture of various concentrations of dissolved oxygen and different aeration methods have been tested in the pilot scale reactor in five months divided into five periods where the temperature was set at 15° C throughout the study.

  6. 15. Challenges during start-up of urine nitrification in an MBBR

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE
