11. Pilot scale partial denitratation coupled anammox: an evaluation
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : 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. LÄS MER
12. Powder Rheology within AM production : Evaluating Compressibility, Permability, & Aeration for 316L Powders Within SLM Processes
M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : 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. LÄS MER
13. Spillway flow behaviours with and without aeration
Master-uppsats, KTH/Teknisk mekanikSammanfattning : 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.

14. Evaluation of PFAS removal from nanofiltration membrane concentrate using foam fractionation
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Per- and polyfluorinated substances (PFASs) have become an urgent topic in the water treatment industry in recent years as a consequence of new scientific discoveries of the correlation between the ingestion of some PFASs and their toxicity in humans and other organisms. PFASs are synthetic compounds present in a variety of products. LÄS MER
15. Energieffektivisering av membranluftrengöring vid högflödesperioder : Studie på en storskalig MBR-pilot på Syvab Himmerfjärdsverket i samarbete med SUEZ Water Technologies and Solutions
Master-uppsats, Karlstads universitetSammanfattning : Membrane BioReactor (MBR) is a wastewater treatment method which combine both biological and physical cleaning. In the membrane tank there is membrane fibres which physically separate wastewater from containing organic material. This causes the membrane fibres to easily build fouling. LÄS MER
