2. 1. Increase of Biogas Production at Wastewater Treatment Plants Addition of urban organic waste and pre-treatment of sludge

   Author : Åsa Davidsson; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; pollution control; Miljöteknik; Environmental technology; Miljöstudier; Environmental studies; biogas; anaerobic digestion; sludge; Wastewater; organic waste; methane;

   Abstract : Anaerobic digestion of organic matter results in the production of biogas, which can be used to replace fossil fuels. There is potential for increased biogas production at wastewater treatment plants by digesting urban organic waste either separately or together with the sludge. Biogas production could also be increased by sludge pre-treatment. READ MORE

4. 2. Improvement of Wastewater Sludge Digestion

   Author : Michael Recktenwald; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anaerobic digestion; biogas; cation-binding agents; enzymes; enzymatic activity; extracellular polymeric substances EPS ; industrial scale trials; methanization; municipal sewage; sludge treatment; wastewater treatment plant;

   Abstract : The reduction of sludge volumes for disposal is a topic of high interest for wastewater treatment plants (WWTP) all over the world. Steadily increasing volumes for disposal create an economic, environmental, legislative and technological challenge. READ MORE

5. 3. 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

6. 4. Enzymatic treatment of wastewater sludge. Sludge solubilisation, improvement of anaerobic digestion and extraction of extracellular polymeric substances

   Author : Joanna Wawrzynczyk; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; pollution control; Environmental technology; sludge treatment; wastewater activated sludge; Proteins; enzymology; Proteiner; enzymologi; cation-binding agents; mass reduction; lectins; extracellular polymeric substances; enzymes; enzymatic activity; anaerobic digestion; biogas; Miljöteknik; kontroll av utsläpp; Biotechnology; Bioteknik;

   Abstract : The processing and disposal of sludge from wastewater treatment plants is an important topic of increasing environmental, ecological, technological, economic and social concern. The large amounts of sludge produced represent an urgent problem today, new treatment methods being very much needed. READ MORE

7. 5. Anammox-based systems for nitrogen removal from mainstream municipal wastewater

   Author : Andriy Malovanyy; Elzbieta Plaza; Adriano Joss; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater; Nitrogen removal; Ion exchange; Deammonification; Anammox; Mainstream; Mark- och vattenteknik; Land and Water Resources Engineering;

   Abstract : Nitrogen removal from municipal wastewater with the application of deammonification process offers an operational cost reduction, especially if it is combined with a maximal use of organic content of wastewater for biogas production. In this thesis, two approaches for integration of the deammonification process into the municipal wastewater treatment scheme were studied. READ MORE
