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. Developing Wastewater-based Early Warning System for the Detection of Disease Outbreaks and Emerging Variants with focus on SARS-CoV-2

   University essay from KTH/Industriell bioteknologi

   Author : Ayda Kiyar; [2023]
   Keywords : wastewater-based epidemiology; early warning system; RT-qPCR; normalization; SARS-CoV-2; avloppsvattenbaserad epidemiologi; förvarningssystem; RT-qPCR; normalisering;

   Abstract : Under covid-19-pandemin har avloppsvattenbaserad epidemiologi (WBE) använts i stor utsträckning som ett komplement till kliniska tester över många delar av världen. Detta projekt syftade till att detektera och kvantifiera belastningen av Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) i avloppsvattenprover med hjälp av Revers transkriptas kvantitativ polymeraskedjereaktion (RT-qPCR).

4. 3. Evaluation of pharmaceutical removal in seven WWTPs : Efficiency of different treatment technologies

   University essay from Stockholms universitet/Institutionen för miljövetenskap

   Author : Viktor Munkhammar; [2023]
   Keywords : Pharmaceuticals; wastewater treatment plant; removal efficiency; biological treatment; ozonation;

   Abstract : Wastewater treatment plants (WWTPs) are originally not constructed to remove pharmaceuticals from the wastewater. Biological treatment technologies used in many WWTPs today, e.g., activated sludge, MBBR and trickling filters, can, however, remove some pharmaceuticals well. READ MORE

5. 4. Ammonium-Based Aeration Control with Iterative Set-Point Tuning in Wastewater Treatment Plants

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Tom Bärnheim; [2023]
   Keywords : adaptive control; ammonium-based aeration control; ammonium feedback control; iterative set-point tuning; process control; wastewater treatment;

   Abstract : In wastewater treatment plants, the amount of ammonium is one example of a measure to determine the quality of the effluent wastewater. Ammonium is regarded as a hazardous chemical for aqueous ecosystems and can cause eutrophication due to its high nitrogen content. READ MORE

6. 5. High-loaded thermophilic anaerobic digestion of mixed sewage sludge : A pilot study

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Santiago Elejalde Bolaños; [2022]
   Keywords : thermophilic anaerobic digestion; volatile fatty acids; mixed sludge; organic loading rate; alkalinity; wastewater treatment plant; termofil rötning; flyktiga fettsyror; blandslam; organisk belastning; alkalinitet; avloppsreningsverk;

   Abstract : Municipal wastewater treatment plants (WWTP) are important infrastructural components in a society and also important for sustainability. In a WWTP the most common treatment configuration is mechanical, biological, and chemical treatment of the wastewater. READ MORE
