1. 1. Techno-Economic Analysis of Dye Separation in Textile Recycling

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : David Lundberg; [2024]
   Keywords : Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

   Abstract : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. READ MORE

3. 2. Modelling Micropollutant Removal Through Ozonation in Wastewater

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Maximiliano Andrés Oportus Foster; [2023]
   Keywords : Micropollutants; water reuse; wastewater treatment models; ozonation; computer modeling; water and environmental engineering; Technology and Engineering;

   Abstract : Proper management of water resources is a key to climate change adaptation and resilience in modern societies. Adequate treatment of wastewater is essential for ensuring the sustainability of the water cycle and the health of the environment and the ecosystems that inhabit it. READ MORE

4. 3. Selected PFAS in the water treatment at the waste-to-energy plant in Umeå : Investigating concentration and composition of selected PFAS in different water treatment steps

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Amanda Carlund; [2023]
   Keywords : ;

   Abstract : The present study investigated the changes in concentration and composition of five selected PFAS substances in the water treatment at the waste-to-energy plant in Umeå. The five PFAS were PFHxA, PFHpA, PFOA, PFHxS and PFOS. As PFAS exists in a variety of consumer products, they will to some extent end up in waste incineration. READ MORE

5. 4. 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

6. 5. Yearly distribution and composition of per- and polyfluoroalkyl substances (PFAS) in Luleå wastewater treatment plant

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Moa Sjöberg; [2023]
   Keywords : PFAS; WWTP; Wastewater treatment; Consumer products; Precursors;

   Abstract : PFAS (per- and polyfluoroalkyl substances) are a large group of substances that are used in a large variety of products because of their unique water and dirt repellent properties. The substances are extremely persistent and can spread over large distances in groundwater, surface water, and in the air, which makes them an environmental and a health concern. READ MORE
