Effects of initial molecular weight on removal rate of dextran in biofilms
Bakke, Rune; Milferstedt, Kim; Kommedal, Roald; Morgenroth, Eberhard (Journal article; Peer reviewed, 2006-05)Degradation kinetics of different size dextrans in a biofilm reactor were evaluated. Degradation rates of dextran standards, measured as time series of oxygen utilisation rates (OUR), decreased with increasing initial ... -
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 ... -
Quantification of biofilm accumulation by an optical approach
Bakke, Rune; Kalvenes, Sigmund; Kommedal, Roald (Journal article; Peer reviewed, 2001-02)Methods for non-invasive, in situ, measurements of biofilm optical density and biofilm optical thickness were evaluated based on Pseudomonas aeruginosa experiments. Biofilm optical density, measured as intensity reduction ...
