• Degradation of polymeric and particulate organic carbon in biofilms 

      Kommedal, Roald (Doctoral theses at NTNU;2003:101, Doctoral thesis; Peer reviewed, 2003)
      Polymeric and particulate organic carbon (POM) are fundamental compounds in the global cycling of carbon, and constitute significant amounts of BOD in municipal wastewater. The main objective of this work is to study ...
    • 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 ...
    • Modeling Pseudomonas aeruginosa biofilm detachment 

      Kommedal, Roald; Bakke, Rune (HiT notat, Working paper, 2003)
      The mechanisms and modeling of surface biofilm detachment are evaluated in this study using data from Pseudomonas aeruginosa experiments and a standard one dimensional mass balance biofilm modeling approach. The aim of ...
    • 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 ...
