  1. 1. A case study of estimating Algal biomass productivity from wastewater treatment facilities in the state of Texas and possible use

    Master-uppsats, KTH/Kemiteknik

    Författare :Gopi Raju Makkena; [2022]
    Nyckelord :Microalgae; Rotating Algal Biofilm RAB ; Flash Hydrolysis; Algal biomass; Biofertilizer; Mikroalger; roterande algbiofilm RAB ; flashhydrolys; algbiomassa; biogödsel;

    Sammanfattning : För att hålla vattendragen och miljön rena, renas avloppsvattnet för att nå ett visst mått innan det släpps ut. Vi gjorde en fallstudie för att utvärdera metoderna som används för att behandla avloppsvatten i tre steg: primär, sekundär och tertiär i delstaten Texas, USA. LÄS MER

  3. 2. Opportunities for increased nutrient recovery at centralised wastewater treatment plants through urine separation

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Hanna Gustavsson; [2021]
    Nyckelord :Nutrient recovery; urine separation; magnesium ammonium phospahte; MAP; ammonium sulphate; AMS; and DHI s WEST;

    Sammanfattning : Municipal wastewater contains a significant amount of nutrients such as phosphorus (P) and nitrogen (N). Therefore have the interest of recovering these nutrients at wastewater treatment plants (WWTP) increased. Nutrient recovery would generate revenue for the WWTP, as it is possible to sell the products as fertiliser. LÄS MER

  4. 3. Evaluating the suitability of carbon source from fermentation of primary filter sludge for biological nutrient removal

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sanna Sahlin; [2021]
    Nyckelord :Wastewater treatment; batch activity tests; NUR tests; anaerobic P release tests; EBPR; denitrification; removal rates; internal carbon source; fermentate; water and environmental engineering; Technology and Engineering;

    Sammanfattning : Traditional biological nutrient removal (BNR) processes in wastewater treatment require access to easily biodegradable carbon in order to achieve sufficient removal. However, a lot of the carbon in the influent wastewater is not directly available for BNR bacteria but need to undergo hydrolysis first. LÄS MER

  5. 4. Enhancement of hydrolysis from co-fermentation of food waste and primary sludge

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Johnny Hagelin; [2021]
    Nyckelord :Environmental engineering; Bioaugmentation; Fermentation; Hydrolysis; Resource recovery;

    Sammanfattning : Research about resource recovery from complex waste streams is getting an increased scientific attention since valuable resources can be produced by sustainable biological means. In anaerobic degradation processes, resources such as volatile fatty acids (VFAs) and biogas are highly coveted. LÄS MER

  7. 5. Hydrolysis of waste activated sludge from pulp and paper mills : effect on dewatering properties and biogas potential by utilizing existing side streams

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Louise Hjalmarsson; [2021]
    Nyckelord :hydrolysis; dewatering properties; biogas; sludge; waste activated sludge;

    Sammanfattning : A big challenge within pulp and paper mills is the large quantities of waste activated sludge (WAS) that is produced during the wastewater treatment. The WAS is made up of biological cells and extra polymeric substances (EPS) and can bind a large amount of water causing difficulties to dewater the WAS. LÄS MER
