1. Mapping spontaneous biological phosphorus removal in a membrane bioreactor process without the anaerobic condition : Investigating the effect of alternative external carbon sources
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Phosphorus removal in wastewater treatment is commonly achieved by chemical precipitation, enhanced biological phosphorus removal (EBPR) or a simultaneous combination of the two. A defined anaerobic condition is widely regarded as the critical element to sustain EBPR. However, this study demonstrates that EBPR is indeed occurring in a 4. READ MORE

2. Experiments on optimal maintenance operations with emphasis on end-of-contract constraints
University essay from Göteborgs universitet/Institutionen för matematiska vetenskaperAbstract : To minimize the unnecessary costs that arise when machines or other objects fail, perhaps needing to be replaced during less than ideal occasions through what is known as reactive maintenance, a more active maintenance policy through which objects are continuously maintained in a preventative manner based on life expectancy or from a cost-perspective, is preferred. Mathematical models can be advantageous to utilize when scheduling these maintenance occasion. READ MORE

3. Innovative Control Strategies for the Partial Nitritation/Anammox Wastewater Treatment Process
University essay from KTH/EnergiteknikAbstract : 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.
