Capabilities of anaerobic granular sludge bed process for the treatment of particle-rich substrates
Tassew, Fasil Ayelegn (Doctoral dissertations at the University of South-Eastern Norway;56, Doctoral thesis, 2020-01-17)High-rate anaerobic reactors have qualities that make them more attractive for anaerobic digestion of organic substrates compared to traditional reactors such as Continuous Stirred Tank Reactor (CSTR). These qualities ... -
Effect of Particulate Disintegration on Biomethane Potential of Particle-Rich Substrates in Batch Anaerobic Reactor
Tassew, Fasil Ayelegn; Bergland, Wenche Hennie; Dinamarca, Carlos; Bakke, Rune (Peer reviewed; Journal article, 2019)An investigation of particle disintegration was carried out using batch anaerobic reactors and a particle-rich substrate from pig manure supernatant. Two types of samples were applied, one high in suspended particles (raw ... -
Granular sludge bed processes in anaerobic digestion of particle-rich substrates
Tassew, Fasil Ayelegn; Bergland, Wenche Hennie; Dinamarca, Carlos; Kommedal, Roald; Bakke, Rune (Peer reviewed; Journal article, 2019)Granular sludge bed (GSB) anaerobic digestion (AD) is a well-established method for efficient wastewater treatment, limited, however, by the wastewater particle content. This review is carried out to investigate how and ... -
Influences of temperature and substrate particle content on granular sludge bed anaerobic digestion
Tassew, Fasil Ayelegn; Bergland, Wenche Hennie; Dinamarca, Carlos; Bakke, Rune (Peer reviewed; Journal article, 2019)Influences of temperature (25–35 °C) and substrate particulate content (3.0–9.4 g total suspended solids (TSS)/L) on granular sludge bed anaerobic digestion (AD) were analyzed in lab-scale reactors using manure as a substrate ...
