  1. 1. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Mehrzad Ghassemi; [2022]
    Nyckelord :Greywater; EBPR; Phosphorus; Biological treatment; Water and environmental engineering; Technology and Engineering;

    Sammanfattning : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes.

  3. 2. Mapping of spontaneous biological phosphorous removal in MBR-process

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Benjamin Fridh; [2020]
    Nyckelord :Polyphosphate poly-P ; Phosphorous;

    Sammanfattning : An unexpected biological removal of phosphorous in IVL Hammarby Sjöstadsverket pilot membrane bioreactor (MBR) wastewater treatment process was investigated by three distinct methods. a) Investigation and quantification of the biological phosphorous uptake (bio-P) capacity by phosphate release tests (PRT), b) validation of bio-P occurrence by granular polyphosphate (poly-P) staining and microscopy and c) metagenomic community structure analysis to map the sludge habitat.

  4. 3. Analys av bottensediment från västra Gotlandsbassängen i Egentliga Östersjön

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Gustav Hållenius; [2018]
    Nyckelord :Baltic Sea; eutrophication; phosphorus; metal; sediment; Östersjön; övergödning; fosfor; metall; sediment;

    Sammanfattning : Rapporten ämnar undersöka bottensediment bärgade från ett område i västraGotlandsbassängen i Östersjön. Östersjön är ett ansträngt bräckvattenhav medutbredda övergödningsproblem, döda bottnar och hotad biologisk fauna. LÄS MER

  5. 4. Optimering av bio-P-processen vid Västra strandens avloppsreningsverk i Halmstad

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Amanda Eriksson; [2018]
    Nyckelord :Enhanced phosphorus removal; EBPR; bio-P; wastewater treatment; PAO; avloppsteknik; Technology and Engineering;

    Sammanfattning : As eutrophication of lakes and oceans is increasing, regulations regarding phosphorus effluents becomes stricter. Consequently, the majority of Sweden’s wastewater treatment plants employs some method for phosphorus removal. LÄS MER
