  1. 21. Life Cycle Assessment of a small scale, solar driven HVR water purification system

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Sharang Kolathur; [2022]
    Nyckelord :life cycle assessment; air gap membrane distillation; solar energy; levelized cost; grid operated system; livscykelanalys; luftgapmembrandestillation; solenergi; utjämnade kostnader; nätdrivet system;

    Sammanfattning : Water purification systems have made access to drinking water easier by treating water sources which previously could not be used for drinking. Such systems however require energy and materials to build and operate which means they have environmental impacts. LÄS MER

  3. 22. Green Protein Hydrogels and Non-dry Aerogels in Water Purification

    Kandidat-uppsats, KTH/Kemi

    Författare :Emanuel Nelsson Vedung; Alexander Singh; Julia Wadefjord; [2022]
    Nyckelord :Aerogel; Hydrogel; Whey Protein Isolate; Water purification; Adsorption; Sustainability;

    Sammanfattning : Having access to clean water is not a certainty for every human being. Today, there are major problems with polluted water that not just affect us humans, but also the ecosystem around us. In recent years, research into making aerogels from protein nanofibrils (PNF) has increased. LÄS MER

  4. 23. Removal Characteristics of Fibrous and Particulate Microplastics : A Study of the Effectiveness of Coagulation-Flocculation- Sedimentation

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Amrith Kumar; [2022]
    Nyckelord :Coagulation; flocculation; jar test; microplastics; sedimentation; water treatment; Burktest; flockning; koagulering; mikroplaster; sedimentering; vattenrening;

    Sammanfattning : The rapid proliferation of microplastics (MPs) over the last few decades have raised alarms about the major environmental and health impacts posed by this anthropogenic source. The widespread propagation and transport of MP particles in water sources have accelerated the need to study the eco- toxicological impacts as well as the efficacy of various removal mechanisms from these critical water sources.

  5. 24. Energieffektivisering av membranluftrengöring vid högflödesperioder : Studie på en storskalig MBR-pilot på Syvab Himmerfjärdsverket i samarbete med SUEZ Water Technologies and Solutions

    Master-uppsats, Karlstads universitet

    Författare :Patrik Bou-Rached; [2022]
    Nyckelord :MBR; membrane air scouring; trans membrane pressure; luftflöde; membranluftrengöring; transmembrantryck;

    Sammanfattning : Membrane BioReactor (MBR) is a wastewater treatment method which combine both biological and physical cleaning. In the membrane tank there is membrane fibres which physically separate wastewater from containing organic material. This causes the membrane fibres to easily build fouling. LÄS MER

  7. 25. Ekosystemtjänster från anlagda och restaurerade våtmarker : Och hur de kan bidra till att de svenska miljökvalitetsmålen uppnås

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

    Författare :Felicia Hjerpe; Alexandra Olsson; [2022]
    Nyckelord :Ecosystem services; Environmental quality objectives; Water purification; Biodiversity; Climate regulation; Ekosystemtjänster; Miljökvalitetsmål; Vattenrening; Biologisk mångfald; Klimatreglering;

    Sammanfattning : Under det senaste seklet har svensk våtmarksareal minskat med en fjärdedel, vilket motsvarar 2,7 miljoner hektar. Detta till följd av ett industrialiserat samhälle med ett starkt intresse i utbyggnad av jordbruk, skogsbruk och vattenkraft. LÄS MER
