1. 1. High levels of nickel from sulphide soil in Umeå's raw water : Modeling of groundwater flow and mass transport in Forslunda aquifer

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Merhawi Belai; [2024]
   Keywords : nickel; sulfide; sulphide; groundwater; modeling; mass transport; Feflow; Umeå; nickel; sulfid; monosulfid; grundvatten; modellering; masstransport; Feflow; Umeå;

   Abstract : The raw water in some of Umeå's abstraction wells has shown high nickel levels for more than a decade. The cause has not been determined but there is an investigation from 2010 where the results indicate sulphide clay found adjacent to two basins used for artificial infiltration. READ MORE

3. 2. Dagvatten blir badvatten : ett gestaltningsförslag på en baddamm i Gränbyparken med naturlig rening

   University essay from SLU/Dept. of Urban and Rural Development

   Author : Ludvig Pärlefors Prado; [2023]
   Keywords : Baddamm; dagvattenrening; naturlig pool; hållbar dagvattenhantering;

   Abstract : Att rena och fördröja dagvatten sker i allt högre grad lokalt. Då dagvattenanläggningarna kommer närmare inpå den bebyggda miljön och i kontakt med stadens invånare, får landskapsarkitekten en viktig roll, genom att utforma öppna dagvattenlösningar. READ MORE

4. 3. Spent Nuclear Fuel under Repository Conditions : Update and Expansion of Database and Development of Machine Learning Models

   University essay from KTH/Kemi

   Author : Maria Abada; [2022]
   Keywords : Spent nuclear fuel; spent nuclear fuel dissolution; spent nuclear fuel corrosion; machine learning model; dissolution predictions; Utbränt kärnbränsle; upplösning av utbränt kärnbränsle; korrosion av utbränt kärnbränsle; maskininlärningsmodeller; prediktioner av upplösning;

   Abstract : Förbrukat kärnbränsle är mycket radioaktivt och behöver därför lagras i djupa geologiska förvar i tusentals år innan det säkert kan återföras till naturen. På grund av de långa lagringsperioderna görs säkerhetsanalyser av de djupa geologiska förvaren. READ MORE

5. 4. Design and Optimisation of an Aquifer Storage and Recovery System - Options for long term storage under natural hydraulic gradients

   University essay from Lunds universitet/Teknisk geologi

   Author : Simon Kreipl; [2021]
   Keywords : Aquifer storage and recovery; well-field design; groundwater modelling; numerical modelling; FEFLOW; Technology and Engineering;

   Abstract : Aquifer storage and recovery (ASR) is a concept where water is stored in an aquifer during times when it is available, thus creating artificial groundwater, which can later be recovered by pumping when it is needed (Pyne, 1995). One ASR cycle consists of a injection, a standby and a recovery phase. READ MORE

6. 5. Remediation of an arsenic-contaminated anoxic aquifer in hjältevad with zerovalent iron : assessment and modelling of sorption strength and solubility of arsenic

   University essay from SLU/Dept. of Soil and Environment

   Author : Kathrin Leicht; [2021]
   Keywords : arsenic remediation; zerovalent iron; anoxic aquifer;

   Abstract : In-situ injection of zerovalent Iron (ZVI) particles to remediate contaminated groundwater is a widely applied approach. However, studies assessing the remediation and immobilisation mechanisms of Arsenic (As) under anoxic field conditions with zerovalent iron particles are lacking, especially for nanosized sulphidated ZVI (S-nZVI) and oxidic shell free ZVI (OSF-nZVI).
