  1. 6. Continuous leaching of phosphorus from sewage sludge ash

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Sofie Göransson; [2022]
    Keywords : Ash leaching; Continuous stirred tank reactor; CSTR; Phosphorus recovery; Sewage sludge ash;

    Abstract : The global demand for food is increasing. Different nutrients are used to increase growth in agriculture and are thus essential for the world ́s food supply. An important and common nutrient is phosphorus. It can be mined, in the form of phosphate, from phosphate rock. READ MORE

  3. 7. Pilot scale partial denitratation coupled anammox: an evaluation

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Tobias Ellingsen; [2022]
    Keywords : mainstream anammox; partial denitratation anammox; partial denitrification anammox; PDA; nitrite inhibition; anammox; water and environmental engineering; Technology and Engineering;

    Abstract : På avloppsreningsverk (ARV) som tillämpar kväverening är den vanligaste tekniken nitrifikation följt av denitrifikation. Denna process kräver omfattande luftning, vilket både är elintensivt och minskar mängden biogas som kan utvinnas. READ MORE

  4. 8. Scale-down modelling of the upstream process for production of Affibody® Molecules

    University essay from KTH/Proteinvetenskap

    Author : Philip Masreliez; [2022]
    Keywords : Scale-down modelling; protein expression; Affibody® molecule; FeedPlate®; EnPresso® B; STR; Nedskalad produktionsmodell; proteinuttryck; Affibodymolekyler; FeedPlate®; EnPresso® B; STR;

    Abstract : I detta projekt har uttrycket av Affibodymolekyler i bioreaktorer av olika volymetriska skalor jämförts för att fastställa om ett tillförlitligt samband mellan de olika bioreaktorernas prestanda kan etableras för att möjliggöra utvecklingen av en nedskalad produktionsmodell för Affibodymolekyler. Baslinjen för jämförelsen i denna studie har varit en enliters- stirred tank reactor (STR) som de andra (mindre) bioreaktorernas prestanda jämfördes med. READ MORE

  5. 9. Nitrogen removal in MBBR : Investigating the effect of temperature

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Abstract : 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.

  6. 10. Phosphorus reduction in wastewater using microalgae with different phosphorus starvation periods

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Fredrika Murby; [2021]
    Keywords : ;

    Abstract : Anthropogenic induced nutrients in the Baltic Sea have led to 97% of it being eutrophic. Phosphorus is regarded the main regulating nutrient, and nearly 25% of the nutrients coming to the Baltic Sea originate from wastewater treatment plants. READ MORE
