1. LEFTOVERS
University essay from KTH/ArkitekturAbstract : Unlike the city calling the project as 'moving city', what actually happening in Kiruna is that demolishing the old part and building a new area. During this process, specific researches were done on each houses by municipality and only few heritages, estimated as culturally valuable, are picked up and will be preserved as it is. READ MORE

2. Mainstream Deammonification process monitoring by bacterial activity tests
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : 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. 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)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

4. 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 landskapsläraAbstract : 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

5. Evaluation of Nitration/Anammox process by bacterial activity tests.
University essay from KTH/Mark- och vattenteknikAbstract : Partial Nitritation/Anammox process (deammonification process), by which occurs oxidation of ammonium to nitrogen gas by autotrophic bacteria in anaerobic conditions, considered to be cost-effective and environmentally friendly method of nitrogen removal. Present research work focuses on achieving a high nitrogen removal degree, thanks to Anammox bacteria, while providing the best performance of the ongoing process. READ MORE
