Determination of kinetic constants from the co-digestion of dairy cow slurry and municipal food waste at increasing organic loading rates
Morken, John; Gjetmundsen, Magnus; Fjørtoft, Kristian (Journal article; Peer reviewed, 2017)The aim of this study was to investigate the performance and the kinetic constants of anaerobic mesophilic CSTR reactors run at increasing organic loading rates (OLR). The reactors were co-digesting dairy cow slurry (DCS) ... -
Pre-treatment methods for straw for farm-scale biogas plants
Fjørtoft, Kristian; Morken, John; Hanssen, Jon Fredrik; Briseid, Tormod (Journal article; Peer reviewed, 2019)This study investigated the effect of five different pre-treatment methods (ammonia (NH3), caustic soda (NaOH), dry milling, hot water and steam explosion) for straw for biogas production. The methods were selected based ...
