  1. 1. Ultrasonication of Spiral Wound Membranes to Mitigate Fouling in Reverse Osmosis

    Master-uppsats, KTH/Kemiteknik

    Författare :Eliot Diklev; [2022]
    Nyckelord :Reverse Osmosis; Spiral Wound Membrane; Ultrasonication; Fouling; Omvänd Osmos; Spirallindat Membran; Ultraljudsbehandling; Igenslamning;

    Sammanfattning : Syftet med den här studien var att undersöka en alternativ slamningsreducerande teknik till spolning, som effektivt kan ta bort biologisk påväxt. Ultraljud undersöktes som en möjlig metod för att ta bort igenslamningen från omvänd osmos med ett spirallindat membran. LÄS MER

  3. 2. Experimental Characterisation and Modelling of a Membrane Distillation Module Coupled to aFlat Plate Solar Collector Field

    Master-uppsats, Högskolan Dalarna/Energiteknik

    Författare :David d’ Souza; [2018]
    Nyckelord :Solar thermal; solar desalination; membrane distillation; permeate gap membrane distillation; spiral-wound module;

    Sammanfattning : An experimental characterisation of a pre-commercial spiral wound permeate gap membrane distillation module was carried out to test its performance at different operating conditions for the purpose of seawater desalination. The experimental setup consisted of a flat plate solar collector field indirectly coupled to the permeate gap membrane distillation module via an inertia tank. LÄS MER

  4. 3. Membrane screening to identify optimal properties when separating organic matter from Bolmen water

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Olivia Söderman; [2017]
    Nyckelord :natural organic matter; ultrafiltration; nanofiltration; drinking water; membrane technology; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Chemistry;

    Sammanfattning : In many places across the northern hemisphere, drinking water treatment plants (WTPs) need to avert the effects of deteriorating quality in surface water sources caused by increasing lev-els of natural organic matter (NOM). The two major factors responsible for this phenomenon, also called brownification, are the greenhouse effect and changes in soil acidification. LÄS MER

  5. 4. Nanofiltration of ultrafiltration permeate fom chemical wastewater

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Martin Gunnarsson; [2017]
    Nyckelord :total organic carbon; nanofiltration; wastewater; ultrafiltration; conductivity; chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : The aim of this report was to investigate the possibility of further cleaning of the wastewater at Dow in Landskrona. Dow produces water based adhesives from acrylic monomers. The wastewater contains different metal ions, surfactants, residual monomers and polymers. LÄS MER
