    Abstract : Träd är viktiga delar av våra städer. De bidrar med många ekosystemtjänster, som klimatreglering, dagvattenhantering och positiva hälsoeffekter. De är också viktiga identitetsskapande element. READ MORE

  3. 2. Evaluation of Partial Nitritation/Anammox processes operated in IFAS mode

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Aleksandra Zdyrska; [2017]
    Keywords : ;

    Abstract : The main aim of the study was to optimize Partial Nitritation/Anammox process operated in pilot-scale integrated fixed film activated sludge (IFAS) mode supplied with low-temperature mainstream wastewater and efficiency evaluation based on laboratory analysis and data from online sensors. Main tasks of research work were to stabilize the ongoing process and find the optimal conditions for maximizing effects of nitrogen removal. READ MORE

  4. 3. Innovative Control Strategies for the Partial Nitritation/Anammox Wastewater Treatment Process

    University essay from KTH/Energiteknik

    Author : Evan Scott; [2016]
    Keywords : ;

    Abstract : The project undertaken in this thesis was proposed by IVL Swedish Environmental Research Institute and performed at their R&D facility Hammarby Sjöstadsverk as a part of the EU funded research project R3 Water. A single stage partial nitritation/Anammox system in a moving bed biofilm reactor (MBBR) was controlled using oxidation reduction potential (ORP) in order to evaluate its utility as control parameter.

  5. 4. Optimized winter wheat production in Kiev region of Ukraine : a case study on cultivation properties and management focusing on sowing date and nitrogen fertilization

    University essay from SLU/Dept. of Soil and Environment

    Author : Jakob Eriksson; Mats Magnusson; [2015]
    Keywords : Triticum aestivum; crop phenology; yield potential; plant stand; overwintering; nitrogen fertilization; sowing date;

    Abstract : Ukraine is the tenth largest wheat producer in the world but average yields are low, about 3 ton ha-1. A better understanding of growth conditions and factors limiting yield is importantin developing strategies to increase grain yield. READ MORE

  6. 5. High-loaded Activated Sludge: Effects of Different Aeration Strategies at Sjölunda WWTP

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Gabriel Persson; [2015]
    Keywords : methane potential; High-loaded activated sludge; activated sludge modelling; aeration strategies; ASM2d; vattenförsörjningsteknik; avloppsteknik; water engineering; environmental engineering; Technology and Engineering;

    Abstract : The activated sludge process has existed for over a century and despite its age the development of new theories, methods and technologies is ongoing. Despite huge technological breakthroughs in the last decades the activated sludge process is still a very energy demanding process however, and it is possible to make significant energy savings by optimizing the aeration strategy of an activated sludge plant.
