  1. 16. Experimental Study of Flow Fields in Moving Bed Biofilm Reactors

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Shea Nee Chew; [2023]
    Keywords : Moving bed biofilm reactors; Biofilm carriers; Mechanical mixing; Mixer configurations; Carrier mixing; Biofilmsreaktorer med rörlig bädd; Biofilmsbärare; Mekanisk blandning; Blandarkonfigurationer; Bärarblandning;

    Abstract : With the rise in global energy prices, as well as energy consumption being the largest source of greenhouse gas emissions, biofilm-based systems utilized for wastewater treatment, such as moving bed biofilm reactors (MBBRs), have grown in popularity for their lower energy consumption compared to conventional activated sludge processes. However, this technology requires large amounts of energy to constantly distribute and suspend its biofilm carrier within the reactor by either aerators or mechanical mixers. READ MORE

  3. 17. Analysis of pervasive climate risks to global rice production at the subnational level

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Qian Mei; [2023]
    Keywords : ;

    Abstract : Rice is a vital crop and main source of calories for half the global population, particularly in the GlobalSouth. Despite increasing demand for rice, climate change, urbanisation, and land use development arethreatening rice production and therefore food security. READ MORE

  4. 18. Att se framtiden i historien : att utforska platsers tidsjup och låta historiken motivera fortsatt utveckling och gestaltning, med fallstudie av Björnsnäs säteri

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Johanna Trozelli; [2023]
    Keywords : landskapsarkitektur; trädgårdshistoria; gestaltning; Björnsnäs; Rudolf Abelin; Trozelli; kulturmiljö; kulturvärde;

    Abstract : Förestående arbete har syftat till att utforska hur landskapsarkitekten kan arbeta med platsers tidsdjup och historiska kontext utifrån sin gestaltande roll. Grunden för arbetet är tesen att platsers historik kan utgöra en resurs och resultera i mer välgrundade utvecklingsförslag. READ MORE

  5. 19. Site suitability assessment for green hydrogen production in the Valencian Community (Spain)

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Alberto Romero Boix; [2023]
    Keywords : Green hydrogen; renewable electricity; solar; wind; water; electrolysis; proton exchange membrane; desalination; levelized cost of hydrogen; Valencian Community.; Grön vätgas; förnybar el; solenergi; vindkraft; vatten; elektrolys; protonbytesmembran; avsaltning; nivåkostnad för vätgas; Valencianska gemenskapen.;

    Abstract : The Next Generation funds have promoted energy transition projects and specially in Spain many green hydrogen projects are being presented throughout the territory. When developing renewable hydrogen-related projects multiple parameters and inputs must be considered since the characteristics of the sites' surroundings will have a great impact in the profitability of the project.
