  1. 1. Synergistic fire- and mechanical effect of biochar and ammonium polyphosphate in epoxy composite

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Anton Olausson; Ludvig Jönsson; [2023]
    Nyckelord :Ammonium polyphosphate; Biochar; Composite; Epoxy; Synergistic effect;

    Sammanfattning : Polymer composites are used in a varying extent and are challenging the use of traditional materials due to the push towards sustainable development. They have replaced steels and aluminum alloys in applications. LÄS MER

  3. 2. Identifying factors that correlate with Enhanced Biological Phosphorus Removal upsets at Lundåkraverket

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

    Författare :Rounak Niranjan; [2021]
    Nyckelord :Enhanced biological phosphorus removal; polyphosphate accumulating organisms; glycogen accumulating organisms; sludge content in aeration basin; nitrates in aeration basin; pH of incoming water; principal component analysis; pairwise correlations; inhibition factors;

    Sammanfattning : The Enhanced Biological Phosphorus Removal (EBPR) process is characterized as the most sustainable process to remove phosphorus from wastewater albeit with high variability in performance efficiency. Thus, unpredictable upsets in the EBPR system is the norm across several wastewater treatment plants throughout Sweden, forcing the hand of the operators to dose higher volume of chemicals to reach the effluent requirements.

  4. 3. 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.

  5. 4. Investigation of Readily Degradable Carbon Source Production by Hydrolyzing Sludge and Reject water at Ängen planned WWTP

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Kartika Novitasari Pranoto; [2020]
    Nyckelord :EBPR; activated sludge; primary sludge; reject water; hydrolysis rate; hydrolysis yield; VFAs; pH; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Technology and Engineering;

    Sammanfattning : As form of effort to mitigate the increase of pollution level that caused by human activity, Ängen wastewater treatment plant (WWTP) will be built in Lidköping as part of the European LIFE project (LIWE LIFE). Ängen WWTP will be operated based on enhanced biological phosphorus removal (EBPR) technology. LÄS MER

  7. 5. 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
