1. 1. High-Loaded Activated Sludge - Improvement of a Solids Retention Time Controlled System

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Kemiteknik (CI)

   Författare :Per Nobel; [2015]
   Nyckelord :avloppsteknik water engineering; environmental engineering; vattenförsörjningsteknik; High-loaded activated sludge; Solids retention time control; Sludge foaming; Activated Sludge Model; Non-settleable solids; Technology and Engineering;

   Sammanfattning : Although 100 years old, the activated sludge system remains inevitable for modern wastewater treatment. Advancements within the development of mainstream nitrogen removal techniques based on anaerobic ammonium-oxidising bacteria have renewed the interest in traditional, high-loaded activated sludge systems for COD removal only.

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

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

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

   Sammanfattning : 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. LÄS MER

4. 3. High-loaded Activated Sludge: Effects of Different Aeration Strategies at Sjölunda WWTP

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

   Sammanfattning : 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.
