1. Modelling control strategies for chemical phosphorus removal at Tivoli wastewater treatment plant
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Wastewater compose an environmental risk as it contains high levels of nutrients, including phosphorus. Wastewater treatment plants (WWTPs) reduce phosphorus by using coagulants that precipitate soluble phosphate into metal phosphate, which is separated by settling. LÄS MER
2. Pilot-scale plant application of membrane aerated biofilm reactor (MABR) technology in wastewater treatment
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : This membrane aerated biofilm reactor (MABR) pilot project was performed at Ekeby wastewater treatment plant (WWTP) in Eskilstuna, Sweden. This plant is facing a future challenge of effluent TN < 10mg/L according to the new standard and the growing population, where higher treatment capacity is needed. LÄS MER
3. Optimal control of clarifier-thickeners
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknikSammanfattning : A computer model for a general clarifier-thickener has been made and used for comparing different strategies for control of such dewatering units through simulations. The model builds on widely acknowledged theory for modelling clarifier-thickeners - discretizing the settling PDE into a set of ODEs so that concentrations of solids at discrete depths inside the unit become the states of the numerical model - and it was written in the Modelica language using the modelling and simulation environment Dymola.

4. Flytslam i Lövsta avloppsreningsverk : påverkande faktorer och potentiella åtgärder
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : Ett avgörande steg i avloppsvattenrening med aktivslammetoden är att slammet kan avskiljas från det renade vattnet. Detta sker oftast i sedimenteringsbassänger. Sedimenteringsproblem är dock vanliga på många avloppsreningsverk, vilket kan leda till att föroreningar följer med utgående vatten. LÄS MER
5. Mass flows of per- and polyfluoroalkyl substances (PFASs) in a Swedish wastewater network and treatment plant
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Per- and polyfluoroalkyl substances (PFASs) are man-made substances that hold unique properties. They are not only oil- and water repellants but also very resistant to degradation. Due to these properties, the applications are endless and PFASs can be found in a wide range of industrial applications and commercial products. LÄS MER
