1. 1. Wastewater Characterisation for Design and Modelling of Primary Settlers at Municipal Wastewater Treatment Plants

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Louise Westin; [2023]
   Keywords : Primary Settling Tank; Wastewater Treatment; Settleometer; Particle Settling Velocity Distribution; Modelling.; Technology and Engineering;

   Abstract : The primary settling tank (PST) is often one of the first treatment steps at a wastewater treatment plant (WWTP) and is the first process in the plant to remove significant amounts of suspended solids. Its role in wastewater treatment however, has oftentimes been neglected and little effort has been made to optimize and model the process. READ MORE

3. 2. How the Choice of Primary Treatment Affects the Biogas Potential of Primary Sludge

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Fanny Blom; [2022]
   Keywords : wastewater treatment; primary treatment; biogas potential; primary settling treatment; rotating belt filter; chemically enhanced primary treatment; environmental engineering; water resources engineering; Technology and Engineering;

   Abstract : The global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. READ MORE

4. 3. Modelling control strategies for chemical phosphorus removal at Tivoli wastewater treatment plant

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Sara Rosendahl; [2021]
   Keywords : Wastewater treatment plant; phosphorus precipitation; control strategy; feedforward; feedback; ASM2d and primary clarifier model.;

   Abstract : 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. READ MORE

5. 4. CFD Modeling and Optimization of Primary sedimentation tank

   University essay from KTH/Vattendragsteknik

   Author : Aibin Zhang; [2017]
   Keywords : VOF model; RNG k-ε model; velocity; turbulence; primary sedimentation tank;

   Abstract : In this project, the flow field characteristics of the simplified 2D rectangular primary sedimentation tank in Syvab wastewater treatment plant were achieved by a transient water-air two phases finite-volume method, applying Volume-Of-Fluid (VOF) model. RNG k-ε turbulence model was also employed to calculate the turbulent kinetic energy and its dissipation rate. READ MORE

6. 5. Modelling the COD Reducing Treatment Processes at Sjölunda WWTP

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Tanya Klingstedt; [2015]
   Keywords : Technology and Engineering;

   Abstract : The main focus of this thesis was to evaluate the possibility of establishing a wastewater treatment model for the main COD removal parts in the water line of Sjölunda Wastewater Treatment Plant (WWTP) located in Malmö, in southern Sweden. The finalised model was used to simulate an increased load of on average 5,000 population equivalents (P.E. READ MORE
