4. 2. 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.

5. 3. Optimization methods for sedimentation and denitrification in activated sludge

   Author : Serena K. R. Hasselblad; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; solids flux; wastewater treatment; secondary clarifier; activated sludge; Geovetenskap; Earth sciences; Geovetenskap; Sedimentology; sedimentologi;

   Abstract : Denitrification on readily biodegradable carbon compounds and separation of biological sludge from effluent water are examples of critical sub-processes for nitrogen removal in activated sludge. The aim of this thesis was to find operational strategies and newmethods to optimize these processes. READ MORE

6. 4. 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

7. 5. Recovery of organic carbon from municipal waste streams

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

   Abstract : 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.
