  1. 6. Ammonium-Based Aeration Control with Iterative Set-Point Tuning in Wastewater Treatment Plants

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Tom Bärnheim; [2023]
    Keywords : adaptive control; ammonium-based aeration control; ammonium feedback control; iterative set-point tuning; process control; wastewater treatment;

    Abstract : In wastewater treatment plants, the amount of ammonium is one example of a measure to determine the quality of the effluent wastewater. Ammonium is regarded as a hazardous chemical for aqueous ecosystems and can cause eutrophication due to its high nitrogen content. READ MORE

  3. 7. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Mehrzad Ghassemi; [2022]
    Keywords : Greywater; EBPR; Phosphorus; Biological treatment; Water and environmental engineering; Technology and Engineering;

    Abstract : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes.

  4. 8. 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

  5. 9. Powder Rheology within AM production : Evaluating Compressibility, Permability, & Aeration for 316L Powders Within SLM Processes

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : André Leo; [2022]
    Keywords : Powder rheology; AM; Additive manufacturing; BPF; Powder bed fusion; SLM; Selective laser melting; FT4 powder rheometer; Compressibility; Permeability; Aeration; Pulver reologi; AM; Additiv tillverkning; BPF; Pulver bed fusion; SLM; Selektiv lasersmältning; FT4 pulver reometer; kompressibilitet; permeabilitet; luftning;

    Abstract : Additive manufacturing with the use of metals have been a steadily increasing field, being able to create products with a higher degree of complexity than traditional processing techniques. SLM is a popular AM process that uses metal powder as feedstock, and one of the key components of this process is the powder rheology. READ MORE

  6. 10. Spillway flow behaviours with and without aeration

    University essay from KTH/Teknisk mekanik

    Author : Noel Köhler; [2022]
    Keywords : Hydropower; Aeration; Computional Fluid Dynamics CFD ; Spillway; Subpressure; Black Water; Spreading;

    Abstract : Cavitation has been known for a long time to cause damages in spillways athydropower plants, aerators are therefore often implemented to prevent this.The majority of the hydropower plants in Sweden are installed in the northernpart of the country. READ MORE
