• Biofilm in Moving Bed Biofilm Process for Wastewater Treatment 

      Wang, Shuai; Parajuli, Sudeep; Sivalingam, Vasan; Bakke, Rune (Chapter, 2019)
      A brief introduction of the long history of biofilm-based wastewater treatment is given together with basics of biofilm behavior and mechanisms in removal and transformation of pollutants. Moving bed biofilm reactor (MBBR) ...
    • Chemical equilibrium model to investigate scaling in moving bed biofilm reactors (MBBR) 

      Sivalingam, Vasan; Ibrahim, Osama M.; Kukankov, Sergey; Omodara, Babafemi; Janka, Eshetu; Wang, Shuai; Dinamarca, Carlos; Haugen, Hildegunn Hegna; Bakke, Rune (Peer reviewed; Journal article, 2019)
      Moving bed biofilm reactor (MBBR) is a robust, flexible and compact technology for treatment of medium to high strength wastewater. However, while treating with high concentration of ammonium, phosphorus and metal ions, ...
    • Effect of Intermittent Aeration in a Hybrid Vertical Anaerobic Biofilm Reactor (HyVAB) for Reject Water Treatment 

      Sivalingam, Vasan; Dinamarca, Carlos; Wakjera, Eshetu Janka; Kukankov, Sergey; Wang, Shuai; Bakke, Rune (Peer reviewed; Journal article, 2020)
      Water from anaerobic sludge dewatering (reject water that is recycled to the inlet main process treatment) from the Knarrdalstrand municipal wastewater treatment plant in Porsgrunn, Norway, contains 2.4 g/L of total chemical ...
    • Modeling temperature effects in anaerobic digestion of domestic wastewater 

      Lohani, Sunil Prasad; Wang, Shuai; Bergland, Wenche Hennie; Khanal, Sanjay Nath; Bakke, Rune (Journal article, 2018)
      A combination of septic tank (ST) and up-flow anaerobic sludge blanket (UASB) as treatment for domestic wastewater was modeled with the anaerobic digestion model 1 (ADM1). The model was used to visualize the influence of ...
    • Treatment of Metformin-Containing Wastewater by a Hybrid Vertical Anaerobic Biofilm-Reactor (HyVAB) 

      Wakjera, Eshetu Janka; Carvajal Rodriguez, Diego Armando; Wang, Shuai; Bakke, Rune; Saldias Dinamarca, Carlos Antonio (Peer reviewed; Journal article, 2019)
      Several series of batch and continuous experiments were performed to investigate the removal of metformin and other contaminants from two wastewaters: wastewater I (WWI) containing 4 mg/L metformin and wastewater II (WWII) ...
