  1. 1. Wastewater Characterisation for Design and Modelling of Primary Settlers at Municipal Wastewater Treatment Plants

    Master-uppsats, Lunds universitet/Industriell elektroteknik och automation

    Författare :Louise Westin; [2023]
    Nyckelord :Primary Settling Tank; Wastewater Treatment; Settleometer; Particle Settling Velocity Distribution; Modelling.; Technology and Engineering;

    Sammanfattning : The primary settling tank (PST) is often one of the first treatment steps at a wastewater treatment plant (WWTP) and is the first process in the plant to remove significant amounts of suspended solids. Its role in wastewater treatment however, has oftentimes been neglected and little effort has been made to optimize and model the process. LÄS MER

  3. 2. Recombinant expression and purification of sugar beet Phytoglobins in Escherichia Coli BL21 (DE3) including metabolic engineering of the heme biosynthesis

    Master-uppsats, Lunds universitet/Tillämpad biokemi; Lunds universitet/Beräkningskemi

    Författare :Pennie Lindblom; Olivia Geel; [2023]
    Nyckelord :Phytoglobin; Heme; δ-ALA; qPCR; SDS-PAGE; Bacterial cultivation; Escherichia coli; BvPgb1.2; ÄKTA; Applied biochemistry; Biology and Life Sciences;

    Sammanfattning : The protein hemoglobin (Hb) is vital for us humans to ensure enough oxygen replacement in the body. Hb-resembling proteins also exist in plants, these are called phytoglobins (Pgbs). Pgbs are very interesting since they can play a considerable role in the development of blood substitutes and iron supplements for human use. LÄS MER

  4. 3. Phosphorous Precipitation in Source Separated Greywater for Direct Environmental Release.

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Ashley Hall; [2022]
    Nyckelord :water; wastewater; source separation; greywater; phosphorous; precipitation; utfällning; Chemical Engineering; Technology and Engineering;

    Sammanfattning : As our understanding of the impact humans have on the environment changes, so too do the mitigation strategies we employ to prevent it. One major source of anthropogenic pollution is wastewater effluent. LÄS MER

  5. 4. Satsvisa laboratorieförsök för utvärdering av kolkällor i denitrifikation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Lisa Tejde; [2022]
    Nyckelord :external carbon source; biological nitrogen removal; denitrification; chemical oxygen demand COD ; step-feed biological nitrogen removal; ethanol; methanol; Brenntaplus VP1; industrial waste products; denitrification batch activity tests; extern kolkälla; biologisk kväverening; denitrifikation; kemisk syreförbrukning COD ; kaskadkväverening; etanol; metanol; Brenntaplus VP1; industriella restprodukter; satsvisa laboratorieförsök;

    Sammanfattning : I takt med att Uppsala växer behöver kapaciteten för avloppsvattenrening på Kungsängsverket byggas ut. För att möta en framtida ökad belastning bedömer Uppsala Vatten & Avfall AB att en kolkälla kommer behöva tillsättas i den biologiska kvävereningen för att effektivisera den heterotrofa denitrifikationen på Kungsängsverket, som idag sker utan tillsats av kolkälla.

  7. 5. Developing a supervised machine learning model for an optimised aluminium addition based on historical data analytics, for clean steelmaking

    Master-uppsats, KTH/Materialvetenskap

    Författare :Arun Kumar Thakur; [2022]
    Nyckelord :Clean steelmaking; Data analytics; De-oxidation; Machine learning; Ren ståltillverkning; Dataanalys; Deoxidation; Maskininlärning;

    Sammanfattning : De-oxidation is an important process in clean steelmaking. Al (Aluminium) is mainly used as de-oxidant and controls the final oxygen content and impact the sulphur removal in steel. Adding optimum amount of Al is critical for steel cleanliness and to reduce cost. LÄS MER
