  1. 6. 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

  3. 7. Aqua Quality Monitoring System : An Aid to Aquafarmers

    Kandidat-uppsats, Blekinge Tekniska Högskola

    Författare :Bhaskar Nagireddy; Sri Ram Nagubathula; [2022]
    Nyckelord :Aquaculture; Calibration; Dissolved oxygen; Marine; pH; Water quality; Turbidity.;

    Sammanfattning : Aquaculture is a multibillion-dollar industry that meets the demand for marine food while enhancing sustainability. Farmers in this area encounter a finite number of issues. The difficulties experienced by aquafarmers in assessing water quality are described in the chapter 3 of  this report. LÄS MER

  4. 8. Investigating the dynamics controlling dissolved organic matter bioreactivity in agricultural stream water and its link to carbon evasion : A statistical analysis

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Sara Schützer; [2022]
    Nyckelord :;

    Sammanfattning : While streams and rivers emit large quantities of CO2 to the atmosphere, both the mechanisms controlling CO2 evasion as well as the sources of CO2 are still uncertain. One potential source of stream CO2 is in-stream degradation of dissolved organic matter (DOM). LÄS MER

  5. 9. Analysis of the water quality dynamics of Lake Vomb; Interactions between water quality profile and cyanobacterial bloom in a eutrophic lake in Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Wiebke Coenen; [2022]
    Nyckelord :Vombsj¨on; Lake profile; Cyanobacteria; Drinking water; Random Forest; Technology and Engineering;

    Sammanfattning : Lake Vomb, located in Sk˚ane, Sweden, provides water for groundwater infiltration, used for the drinking water supply of several municipalities, including Malm¨o. The lake is in a bad ecological condition with intense algae blooms during summer. Cyanobacteria dominate mentioned blooms in 2021 posing the threat of releasing cyanotoxins. LÄS MER

  7. 10. Nitrogen removal in MBBR : Investigating the effect of temperature

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

    Författare :Rediet Tezera Tafese; [2022]
    Nyckelord :Wastewater; Nitrogen removal; Nitrification; Denitrification; MBBR; Cold temperature; Avloppsvatten; Kväverening; Nitrifikation; Denitrifikation; MBBR; låg temperatur;

    Sammanfattning : The project undertaken in this thesis was performed at MittSverige Vatten och Avfall (MSVA) in cooperation with the Swedish Environmental Research Institute (IVL). The effect of temperature on nitrogen removal using moving bed biofilm reactor (MBBR) was controlled using two separate lines by investigating the influence of temperature on nitrification, pre-denitrification, and post- denitrification in a pilot plant scale.
