  1. 11. Utveckling av marknader för avfallsbaserade resurser : En fallstudie på återanvändning av komplexa avfallsströmmar ur ett värdekedjeperspektiv

    Master-uppsats, Linköpings universitet/Industriell miljöteknik

    Författare :Elsa Bertils; Herman Elvingson; [2019]
    Nyckelord :waste; markets; market regulation; reuse; recycling; resource efficiency; value chain; sludge; bottom ash; slag; organic fertilizer; waste policy; policy; avfall; marknader; återvinning; återanvändning; resurseffektivitet; värdekedja; rötslam; biogödsel; slaggrus; bottenaska; Revaq; SPCR 120; handel; avfallslagstiftning; styrmedel; styrning;

    Sammanfattning : Immense amounts of waste are generated daily by our society, and the management of these streams is a critical societal function. Part of this work is reusing and recycling materials with attractive properties, which is also an imperative step towards circular material flows. LÄS MER

  3. 12. Application of volatile fatty acids from waste as an external carbon source for the denitrification process

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

    Författare :Chengyang Pan; [2019]
    Nyckelord :Volatile fatty acids VFAs ; Denitrification; External carbon sources; Wastewater treatment; Manometric method; Flyktiga fettsyror VFAs ; Denitrifikation; Externa kolkällor; Avloppsrening; Manometrisk metod;

    Sammanfattning : The gap between resource demand for the industrialized world and non-renewable feedstock like fossil fuels, essential agricultural fertilizer is getting increasingly severe, which has resulted in alarming-increasingly impacts on worldwide environmental problems. Meanwhile, wastewater treatment plants (WWTPs), as an essential facility for urbanization, is also confronting new rising challenges such as energy consumption and operation costs rather than only improving effluent wastewater quality.

  4. 13. Development of a GIS model for water accounting in Jordan: focus on irrigation and energy usage in the water sector

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

    Författare :Daniel Pastor Pascual; [2019]
    Nyckelord :;

    Sammanfattning : With a water availability of less than 100 m3 per capita and year, Jordan is suffering extreme water-scarcity. To its intrinsic limited water resources more pressure is being added every year as a result of socioeconomic factors, such as the accelerated population growth, and a reduction of rainfalls and increase of evaporation as consequence of climate change.

  5. 14. Online-instrumentering på avloppsreningsverk : status idag och effekter av givarfel på reningsprocessen

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Marcus Ahlström; [2018]
    Nyckelord :Sensor faults; off-set; bias; drift; sensor; instrument; instrumentation; Benchmark Simulation Model no. 2; BSM2; activated sludge process; pre-denitrification; wastewater; wastewater treatment; Givarfel; bias; drift; givare; instrument; instrumentering; Benchmark Simulation Model no. 2; BSM2; aktivslamprocess; fördenitrifikation; avloppsvatten; avloppsrening;

    Sammanfattning : Effektiviteten av automatiserade reningsprocesser inom avloppsreningsverk beror ytterst på kvaliteten av de mätdata som fås från installerade instrument. Givarfel påverkar verkens styrning och är ofta anledningen till att olika reglerstrategier fallerar. LÄS MER

  7. 15. Pilot-scale plant application of membrane aerated biofilm reactor (MABR) technology in wastewater treatment

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

    Författare :Qianqian Li; [2018]
    Nyckelord :Membrane aerated biofilm reactor; municipal wastewater treatment; nitrogen removal; SND-MBR; Zeelung; Membranbelukt biofilmreaktor; kommunal avloppsrening; kväveavlägsnande; SNDMBR; Zeelung;

    Sammanfattning : This membrane aerated biofilm reactor (MABR) pilot project was performed at Ekeby wastewater treatment plant (WWTP) in Eskilstuna, Sweden. This plant is facing a future challenge of effluent TN < 10mg/L according to the new standard and the growing population, where higher treatment capacity is needed. LÄS MER
