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

   Master-uppsats, Lunds universitet/Industriell elektroteknik och automation

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

   Sammanfattning : 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. LÄS MER

3. 2. Towards Water Resource Recovery Facilities : Environmentally Extended Techno-Economic Assessment of Emerging Sewage Sludge Management Technologies in Sweden

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Harry Tibbetts; [2023]
   Nyckelord :Circular Economy; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrothermal Carbonisation; Cirkulär ekonomi; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrotermal Carbonization;

   Sammanfattning : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). LÄS MER

4. 3. Pyrolysis of Municipal Sewage Sludge to get a phosphorus rich char residue for soil improvement

   Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Shahin Shamim; [2023]
   Nyckelord :Sewage Sludge-Phosphorus-Pyrolysis- Heavy metals; Cadmium; Lead; Nickle; Copper; Chromium; Zinc; Biochar; Heating value; Fertilizer- Thermal conversion;

   Sammanfattning : Sewage sludge is a byproduct of wastewater treatment plants. It is a kind of waste. however, it contains several valuable nutrients like phosphorous and nitrogen that are used to rich the soil as a fertilizer compound. LÄS MER

5. 4. Utvärdering av långtidstester med aktivt kol och anjonbytare för avskiljning av läkemedelsrester och PFAS från kommunalt avloppsvatten : Reningseffektivitet, kostnad och klimatpåverkan

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Sofia Olsson; [2023]
   Nyckelord :Pharmaceuticals; PFAS; PFOS; Activated Carbon; Anion Exchange; Advanced Treatment; Wastewater Treatment Plant; Cost; Climate Impact; Läkemedel; PFAS; PFOS; Aktivt kol; Anjonbytare; Avancerad rening; Avloppsreningsverk; Kostnad; Klimatpåverkan;

   Sammanfattning : Avloppsreningsverk utgör en viktig spridningsväg för läkemedelsrester till den akvatiska miljön. Även per- och polyfluorerade alkylsubstanser (PFAS) har påvisats i utgående vatten från avloppsreningsverk. För att minska utsläpp av dessa krävs ett kompletterande reningssteg. LÄS MER

7. 5. Biogas Potential in the North of Sweden : Inventory and Techno-Economic Assessment of Substrates for an Increased Biogas Production in Norrbotten

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Alma Fahlén Hammar; [2023]
   Nyckelord :Biogas; anaerobic digestion; AD; Norrland; bioenergy; fossil-free; chemical engineering; Chemistry; Technology and Engineering;

   Sammanfattning : Great investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the production of alternative energy sources needs to intensify.
