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

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

   Abstract : 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. READ MORE

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

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

   Abstract : 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.

5. 3. Comparative analysis of pathogen occurrence in wastewater : management strategies for barrier function and microbial control

   Author : Jakob Ottoson; Bengt Hultman; Roland Schertenleib; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bacteria; parasites; treatment; Water engineering; Vattenteknik;

   Abstract : This project was initiated to fill knowledge gaps on the occurrence of pathogens in different streams of wastewater, e.g. greywater and domestic wastewater. READ MORE

6. 4. Anaerobic Treatment of Agricultural Residues and Wastewater - Application of High-Rate Reactors

   Author : Wilson Parawira; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biochemical technology; Biokemisk teknik; opaque beer brewery wastewater; UASB; two-stage; co-digestion; sugar beet leaves; solid potato waste; methane yield; biogas; Anaerobic digestion; agricultural residues;

   Abstract : The production of methane via anaerobic digestion of agricultural residues and industrial wastewater would benefit society by providing a clean fuel from renewable feedstocks. This would reduce the use of fossil-fuel-derived energy and reduce environmental impact, including global warming and pollution. READ MORE

7. 5. Upflow anaerobic sludge blanket reactor : modelling

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

   Abstract : 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.
