1. 1. Evaluating the suitability of carbon source from fermentation of primary filter sludge for biological nutrient removal

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Sanna Sahlin; [2021]
   Nyckelord :Wastewater treatment; batch activity tests; NUR tests; anaerobic P release tests; EBPR; denitrification; removal rates; internal carbon source; fermentate; water and environmental engineering; Technology and Engineering;

   Sammanfattning : Traditional biological nutrient removal (BNR) processes in wastewater treatment require access to easily biodegradable carbon in order to achieve sufficient removal. However, a lot of the carbon in the influent wastewater is not directly available for BNR bacteria but need to undergo hydrolysis first. LÄS MER

3. 2. 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

4. 3. Diurnal variation in methane flux in a low-arctic fen in Southwest Greenland

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Bjarne Munk Lyshede; [2012]
   Nyckelord :geography; physical geography and ecosystem analysis; diurnal; methane; wetland; Arctic; Greenland; Earth and Environmental Sciences;

   Sammanfattning : Popular science: A Day in the Life of a Methane Bog Methane gas is continuously released from wetlands around the world. In Kobbefjord, Greenland the release of methane is low during the cold of winter and higher in warm summer months. But the amount released also varies from day to night; a pattern that has to do with both temperature and light. LÄS MER

5. 4. Hydrolys av primärslam för förbättrande av biologisk fosforreduktion vid behandling av hushållsavloppsvatten [Hydrolysis of primary sludge for enhancement of biological phosphorus removal in household wastewater]

   Magister-uppsats, Tema vatten i natur och samhälle

   Författare :Erik Elfving; [2005]
   Nyckelord :household wastewater; enhanced phosphorus removal; hydrolysis; primary sludge; volatile fatty acids;

   Sammanfattning : Hammarby Sjöstad is a new district of southern Stockholm built with focus on reduced environmental impact by recirculation of materials and sustainability. The environmental goals aim to cut the water consumption by half and a separate storm water treatment. LÄS MER
