  1. 6. How does hydropeaking and geological substrate affect aquatic macroinvertebrates in a regulated river?

    University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Author : Andreas Vernby; [2021]
    Keywords : Hydropeaking; geological substrate; aquatic macroinvertebrates; EPT species; Hester-Dendy samplers; Korttidsreglering; geologiskt substrat; akvatiska makroevertebrater; EPT; Hester-Dendy-provtagare;

    Abstract : Hydropower is an important source of renewable energy, but is often a cause of degradation to river ecosystems. Hydropeaking, i.e. the frequent alteration of discharge, is a process involved in hydropower generation and has been proven to affect aquatic organisms negatively. READ MORE

  3. 7. Removal of PFASs and Uranium from Drinking Water Using SorbixTM Anion Exchange Resin : Effects of Sodium Chloride on the Removal Efficiency

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Fawaz Rustum; [2021]
    Keywords : Perfluorinated; polyflourinated; adsorption; fluorotelomer; salt; perfluorerade; polyfluorerade; adsorption; fluorotelomer; salt;

    Abstract : The increasing awareness towards PFAS pollution makes it increasingly important to treat. Many agencies over the globe, including the Swedish Food Agency, are introducing ever so strict control over PFASs in drinking water. READ MORE

  4. 8. Modelling the Nordic Hydro Power System with Spine Toolbox

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Angelica Waernlund; [2021]
    Keywords : ;

    Abstract : In the Nordic power system, the largest balancing resource is hydro power. For future developments of the Nordic power system with more renewable and varying energy, such as wind power, the hydro power and its limitations must thus be taken into account. To be able to study this, a model with these limitations is needed. READ MORE

  5. 9. Removal of pharmaceutical residues from wastewater by oxidation with ozone

    University essay from KTH/Resursåtervinning

    Author : Frida Söderström; [2021]
    Keywords : ozonation; adsorption; pollutants; pharmaceuticals; wastewater; ozonering; adsorption; föroreningar; läkemedel; vattenrening;

    Abstract : Avloppsreningsanläggningar är idag utformade för att rena bort föroreningar i form av organiskt material, suspenderade fasta ämnen och växtnäringsämnen (exempelvis fosfater och nitrater). Myndighet i Sverige har satt upp restriktioner och lagar gällande hur mycket av de olika föroreningarna som det är okej att utgående vatten innehåller. READ MORE

  6. 10. Carbon dioxide dynamics in agricultural streams : Investigation of two streams draining catchments dominated by agricultural land

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Albin Bostner; [2020]
    Keywords : Carbon dioxide; dynamics; streams; agriculture; oversaturation; metabolic control; hyrdological control; Koldioxid; koldynamik; bäckar; jordbruk; övermättat; metabolisk kontroll; hydrologisk kontroll;

    Abstract : In recent years, streams draining agricultural land has been suggested to exhibit high carbon dioxide (CO2) concentrations when compared to streams draining other land-types. The transport of carbon from land to ocean is mainly occurring through the chain of inland waters, and with agricultural land today representing 40% of all continental area many of these inland waters are influenced by agricultural land.
