21. Modelling control strategies for chemical phosphorus removal at Tivoli wastewater treatment plant
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Wastewater compose an environmental risk as it contains high levels of nutrients, including phosphorus. Wastewater treatment plants (WWTPs) reduce phosphorus by using coagulants that precipitate soluble phosphate into metal phosphate, which is separated by settling. LÄS MER
22. Separation of microfibers from laundry waste water by hydrocyclone : In cooperation with Electrolux Professional
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Microfibers, textile fibres shorter than 5 mm, and are shed from fabrics during wear and released into the laundry effluent during washing. When passed through the wastewater treatment plant (WWTP), they adsorb toxins, heavy metals and pathogens before being released into the environment. LÄS MER
23. Bromatreducering i den biologiska denitrifikationsprocessen – påverkan av bromat och nitrat
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Behovet av att rena avloppsvatten från mikroföroreningar, såsom läkemedelsrester, har uppmärksammats de senaste åren då analysmetoderna har förbättrats och kunskapen om riskerna kring utsläppen har ökat. Detta har ökat intresset för att implementera ozonering som ett avancerat reningssteg på avloppsreningsverk i Sverige och i andra länder. LÄS MER
24. Removal of per- and polyfluoroalkyl substances(PFAS) from contaminated leachate usingaeration foam fractionation
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Leachate from landfills is contaminated in many ways and per- and polyfluoroalkyl substances (PFAS)-contamination is one of them. Recent studies have demonstrated the environmental and human concerns of PFAS. Therefore, the treatment of leachate is important. LÄS MER
25. Influence of Climate Change on Building Effluent Wastewater Temperature in Stockholm by 2040
Master-uppsats, KTH/Energiteknik; KTH/Farkostteknik och SolidmekanikSammanfattning : This report aims to give predictions of Stockholm’s region climate (especially temperature and precipitations) by 2040 and describe the consequences of possible climate changes on the building effluent water temperature and flowrate. First, I did an extensive review of the literature about climate change and climate prediction in Stockholm’s area in order to suggest probable climate scenarios for 2040, using climatic data from the reference period 1960-1990.
