  1. 1. Evaluation of long-term effects of excavated sulfide-bearing rock : - A case study in western Sweden

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

    Author : Ida Sundblom; [2022]
    Keywords : sulfide-bearing rock; acid rock drainage; sulfide oxidation;

    Abstract : Sulfide-bearing rock that is excavated in conjunction with construction projects can cause environmental and construction engineering problems. Sulfidic minerals oxidize when they are exposed to an oxidant and water, which can make them generate acid rock drainage (ARD) with high concentrations of metals and sulphate. READ MORE

  3. 2. Cradle-to-Gate LCA of Water Treatment Alternatives : A case study performed for Norrvatten’s future waterwork expansion

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Siddharth Selvarajan; [2021]
    Keywords : Life cycle assessment; Water purification method; Potable water production; Microbiological barrier; Activated carbon; Sludge separation; Livscykelbedömning; Vattenreningsmetod; Produktion av dricksvatten; Mikrobiologisk barriär; Aktivt kol; Slamavskiljnin;

    Abstract : Norrvatten is a municipal association which owns a water treatment plant capable of supplying good quality drinking water to the consumers in the associated neighbouring municipalities. After preliminary investigations for the future year of 2050, there were estimates which suggest a potential water quality degradation in the lake which supplies the raw water for treatment due to uncertain future climatic conditions and other forms of pollutions from the surrounding.

  4. 3. Brunifiering av boreala sjöar och vattendrag : en kunskapsöversikt och analys av trender i vattenkemin hos tre norrländska bäckar

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Sebastian Carlzon; Andreas Uller; [2020]
    Keywords : brunifiering; DOC; Krycklan; dricksvatten;

    Abstract : Brunifiering av ytvatten är idag ett växande problem i många boreala vattensystem. Syftet med studien var att undersöka hur det rådande kunskapsläget ser ut kring brunifiering av ytvatten i boreala sjöar och vattendrag. Studien innefattade även att undersöka bäckar i krycklans avrinningsområde utanför Umeå. READ MORE

  5. 4. Characterisation of free and conjugated protease inhibitors from Solanum tuberosum

    University essay from Uppsala universitet/Institutionen för kemi - BMC

    Author : Kristoffer Lundmark; [2017]
    Keywords : enzyme; trypsin; chymotrypsin; pancrease protease; serine protease inhibitors; SPI; potato tubers; potato; Solanum tuberosum; immobilized; aluminium oxide membranes; inhibitor-enzyme interaction;

    Abstract : The main purpose of the master thesis project is to investigate the influence of selected serine protease inhibitors (SPI) on the catalytic action of the serine proteases chymotrypsin and trypsin, in a conjugated and non-conjugated state. The inhibitors included for this study were extracted from Solanum tuberosum, i.e.common potato. READ MORE

  6. 5. A comparison of two methods to reduce internal phosphorus cycling in lakes: aluminium versus phoslock

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Natàlia Blázquez Pallí; [2015]
    Keywords : aluminium; phoslock; phosphorus; lake; restoration; adsorption; treatment;

    Abstract : Sediment nutrient inactivation through P binding agents is one of the most common management strategies used to prevent potential P release to lake water. Al-based compounds (aluminium sulphate, Al2(SO4)3·18(H2O)) and a modified lanthanum-based clay material called Phoslock are among the products that can be used to chemically bind P permanently in sediment.
