1. 6. Post-IR IRSL dating of K-feldspar from Loess at Lowland Point, SW England : Developing a Chronology for Past Climate Records

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Elin Törnqvist; [2022]
   Keywords : loess; post-IR IRSL; Lowland Point; SW England; Quaternary; löss; post-IR IRSL; Lowland Point; England; kvartär;

   Abstract : Loess deposits are terrestrial clastic sediments derived from aeolian deposition. Loess is transported in periglacial conditions and was mainly deposited in cold environments around glaciers during the Quaternary period. READ MORE

3. 7. Våtmarker i Helsingborg : en analys av nio våtmarker anlagda längs Råån

   University essay from SLU/Dept. of People and Society

   Author : Alexander Andersson; [2022]
   Keywords : våtmarker; Råån; kväverening; sedimentering; vattenrening; våtmark; Ormastorp; Norra Vallåkra; Bälteberga; Wetlands; nitrogenretention; sedimentation; water purification; ekosystemtjänster;

   Abstract : Den här uppsatsen belyser våtmarkers positiva miljöpåverkan. Med hjälp av historiskt kartmaterial av Skånes historiska landskap visas landskapet och framför allt Råån förändring kopplat till utdikningsprojekten som påbörjades på 1800-talet. READ MORE

4. 8. Evaluating the suitability of carbon source from fermentation of primary filter sludge for biological nutrient removal

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Sanna Sahlin; [2021]
   Keywords : Wastewater treatment; batch activity tests; NUR tests; anaerobic P release tests; EBPR; denitrification; removal rates; internal carbon source; fermentate; water and environmental engineering; Technology and Engineering;

   Abstract : Traditional biological nutrient removal (BNR) processes in wastewater treatment require access to easily biodegradable carbon in order to achieve sufficient removal. However, a lot of the carbon in the influent wastewater is not directly available for BNR bacteria but need to undergo hydrolysis first. READ MORE

5. 9. Treatment of dissolved metals in highway runoff water : Pilot-scale trial with four reactive filter media and sand filter

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Serena Bianchi; [2021]
   Keywords : stormwater treatment; metal removal; adsorption; reactive filter media; sand filtration; Petrit-T; Polonite; D-Rainclean; Filtralite-P; de-icing salt; pressure drop; filter clogging; rening av dagvatten; avl ̈agsnande av metaller; adsorption; reaktiva filterme- dier; sandfiltrering; Petrit-T; Polonite; D-Rainclean; Filtralite-P; avisningssalt; tryckfall; filterstoppning;

   Abstract : The increasing highway traffic is leading to higher and higher levels of pollutants in the stormwater, such as suspended solids, metals, oils, nutrients and PAH. This runoff water causes the degradation of water bodies quality, leading to increased interest in the treatment of highway runoff for the removal of contaminants. READ MORE

6. 10. Evaluation of Dissolved Air Flotation for Water Purification: With Focus on Floc Characteristics and PFAS

   University essay from KTH/Kemiteknik

   Author : Ludwig Löf; [2021]
   Keywords : Water treatment; Sedimentation; Flotation; PFAS; Zeta potential; Vattenbehandling; Sedimentering; Flotation; PFAS; Zeta potential;

   Abstract : I detta projekt har experiment utförts med mål att förse kommunalförbundet Norrvatten med data som kan användas som underlag för beslutsfattande angående om deras fällningslinjer i vattenreningsprocessen ska köras i flotation eller sedimentering. För detta ändamål har koncentrationen av poly- och perfluorerade alkylsubstanser (PFAS) samt karaktär av agglomererade partiklar (flockar) undersökts och jämförts mellan fällningslinjer som körs i olika konfigurationer.
