1. 1. Upflow anaerobic sludge blanket reactor : modelling

   Författare :Raul Rodriguez; Luis Moreno; Olle Wahlberg; Gunno Renman; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; wastewater; anaerobic treatment; modelling; UASB reactor.; Chemistry; Kemi;

   Sammanfattning : Anaerobic treatment is widely used around the world as a biological stage in both domestic and industrial wastewater-treatment plants. The two principal advantages of anaerobic over aerobic treatment are the production of biogas, which can be used as fuel, and the lower rate of biomass production, which results in lower maintenance costs for the plant.

3. 2. Anaerobic treatment of wastewater in a UASB reactor

   Författare :Larisa Korsak; Luis Moreno; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic treatment; UASB; granular biomass; methanogenic activity; modelling; axial dispersion; Chemical engineering; Kemiteknik;

   Sammanfattning : The anaerobic treatment of waste water has been studied with an emphasis on the Up- flow Anaerobic Sludge Blanket (UASB) reactor. A model to describe the processes occurring in a UASB reactor was developed and an experimental study of the anaerobic wastewater treatment systems in Nicaragua was also performed. LÄS MER

4. 3. Recovery of organic carbon from municipal waste streams

   Författare :Isaac Owusu-Agyeman; Elzbieta Plaza; Zeynep Cetecioglu; Irini Angelidaki; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Volatile fatty acid; Anaerobic granules; Co-digestion; Municipal waste; Chemical Engineering; Kemiteknik;

   Sammanfattning : The focus of the current study was on the recovery of carbon from municipal bio-waste streams. Firstly, the relationship between methanogenic pathways and the properties of anaerobic granules was studied using two pilot-scale upflow anaerobic sludge blanket (UASB) reactors with different granule size distribution.

5. 4. Nutrient recovery from waste streams through struvite formation

   Författare :Maryam Latifian; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; struvite; nutrient; phosphorus; nitrogen; wastewater treatment; anaerobic digestion; urine;

   Sammanfattning : Eutrophication or the nutrient enrichment of water bodies, typically by nitrogen and phosphorus has adversely affected the aquatic life and the quality of water. Governments have been forced to take actions in order to reduce the release of these nutrients into the environment. LÄS MER

7. 5. Closing the Loop by Combining UASB Reactor and Reactive Bed Filetr Technology for wastewater Treatment : Modelling and Practical Approaches

   Författare :Raúl Rodríguez-Gómez; Gunno Renman; Björn Vinnerås; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bench-scale experiment; Modelling; Polonite; Sorbulite; UASB; Wastewater; Mark- och vattenteknik; Land and Water Resources Engineering;

   Sammanfattning : A laboratory-scale upflow anaerobic sludge blanket (UASB) reactor followed by a packed bed reactor (PBR) filled with Sorbulite® in the lower part and Polonite® in the upper part was used to treat household wastewater in a 50-week experiment. A model was developed to describe the performance of the UASB reactor, including mass transfer through the film around anaerobic granules, intra-particle diffusion and bioconversion of the substrate.
