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. Method Application of PST-Removal On Pressure-Sensitive Adhesive Laminated Paper: An Experimental Case Study

   University essay from Göteborgs universitet/Institutionen för kulturvård

   Author : Johan Norrman; [2022-11-03]
   Keywords : paper conservation; laminated paper; pressure-sensitive adhesive lamination; delamination; methodology;

   Abstract : In this thesis the plausibility of applying methods and techniques for the removal of pressure-sensitive tapes (PSTs) in the delamination of pressure-sensitive adhesive laminations (PSA-laminations) is examined. The thesis also addresses if delamination is necessary and can be justified in regards to conservation theory, abiding to the concepts and notions of balance between material retention and material loss, reversibility, authenticity, and minimal intervention.

4. 3. 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

5. 4. Standard Compliance and Quality Assurance of Lighting Products : Creating a setup for measuring Short Term Flicker Perceptibility and Stroboscopic Visibility Measure

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Julia Wollter; Alexander Willemsen; [2021]
   Keywords : ;

   Abstract : New EU regulations are currently taking effect, which means there will be stricter requirements on lighting units and more necessity for labs to perform photometric quality control. In the project a flickermeter setup was constructed at the Swedish Energy Agency's lab for performing quality assurance of luminaries by measuring the relevant metrics PST, SVM, and ITHD. READ MORE

6. 5. Simulating Patient Flows in a Cancer Clinic

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Christian Lejdström; [2020]
   Keywords : Discrete Event Simulation Radiotherapy; Medicine and Health Sciences;

   Abstract : Planning resources in cancer care is difficult due to system complexity, varying resource availability and uncertain demand. It has become so complex that the analysis of treatment processes in cancer clinics cannot be done analytically [12]. Therefore, in this thesis a model of a cancer clinic is developed using discrete event simulation. READ MORE
