1. 1. Pilotstudie av källsorterande avloppslösning : Identifiering av systemlösning för källsorterat avloppsavfall i Sydöstra staden i Uppsala

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Linnea Ekblad; [2022]
   Nyckelord :source separating sewage system; urine diversion; anaerobic digestion; wastewater treatment plant; källsorterande avloppssystem; urinsortering; rötning; reningsverk;

   Sammanfattning : Utanför Uppsalas stadskärna planeras det att bygga en ny stadsdel till år 2050, kallad Sydöstra staden. Uppsala kommun vill vara i framkant gällande hållbar stadsplanering och är därför intresserade av att utreda möjligheter till att tillvarata resurser i avloppsvattnet, som ett alternativ till konventionell rening.

3. 2. Produktion av flyktiga fettsyror genom anaerobisk rötning av pappersmassa och papperslam

   M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Abdla Lara; [2022]
   Nyckelord :VFA production; pulp and paper sludge; anaerobic digestion; MBR;

   Sammanfattning : Recently, there has been an increased interest in the production of volatile fatty acids from pulp and paper sludge using an immersed membrane bioreactor during anaerobic digestion. The production of biogas through anaerobic digestion has been a hot topic in recent years, but it is no longer economically viable due to competition from fossil fuels. LÄS MER

4. 3. Mapping spontaneous biological phosphorus removal in a membrane bioreactor process without the anaerobic condition : Investigating the effect of alternative external carbon sources

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Ross Roberts; [2020]
   Nyckelord :enhanced biological phosphorus removal; PAO; anoxic; carbon source; ethanol; ORP;

   Sammanfattning : Phosphorus removal in wastewater treatment is commonly achieved by chemical precipitation, enhanced biological phosphorus removal (EBPR) or a simultaneous combination of the two. A defined anaerobic condition is widely regarded as the critical element to sustain EBPR. However, this study demonstrates that EBPR is indeed occurring in a 4. LÄS MER

5. 4. Limiting microplastic pollution from municipal wastewater treatment : A circular economic approach

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Jordy van Osch; [2020]
   Nyckelord :Microplastics; circular economy; wastewater treatment plant; resource recovery; Multi-criteria analysis;

   Sammanfattning : The increasing amount of microplastics found in the environment have underscored the urgency to identify, develop and deploy scenarios in which municipal wastewater treatment plants (MWWTPs) limit the release of urban microplastics into the environment. Simultaneously, the global trend towards a circular economy has defined the conditions for these scenarios in relation to the water-energy- nutrient nexus. LÄS MER

7. 5. Stable increase of organic loading rate in anaerobic membrane bioreactors working at ambient temperature

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Jean Monhonval; [2015]
   Nyckelord :environmental engineering; anaerobic membrane bioreactor; stability indicators; ambient methanization; stable increase organic loading rate; vattenförsörjningsteknik; avloppsteknik; water engineering; Technology and Engineering;

   Sammanfattning : Anaerobic processes are an interesting alternative to treat wastewaters instead of aerobic treatments as it allows recovery of energy with the produced biogas while removing organic matter. In the industry, lots of low-strength industrial wastewaters are available and unused for biogas production due to their low concentration of organic material and high volumes (slaughterhouse wastewaters, dairies and beverages industries, oils and fats producers).
