  2. 1. Dynamic Modeling of Nitrifying Trickling Filters

    Author : Torsten Wik; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed parameter system; Trickling Filter; Biofilm; Process Model; Experiments; Wastewater; Dynamics;

    Abstract : Trickling filters, one kind of biofilm reactors, for removal of nitrogen in municipal wastewater are presently increasing in number in Sweden. For improved control and operation of wastewater treatment plants, where such reactors are used, dynamic models describing their behavior are necessary. READ MORE

  4. 2. On Modeling the Dynamics of Fixed Biofilm Reactors. With focus on nitrifying trickling filters

    Author : Torsten Wik; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operation; transfer functions; biofilm reactors; adsorption; dormancy; modeling; dynamics; nitrification;

    Abstract : Fixed biofilms, which are matrix-enclosed populations of organisms attached to solid surfaces, are increasingly used in environmental biotechnology processes, such as the treatment of potable water and wastewater. This thesis aims to give some insight into the dynamic modeling of biofilms and fixed biofilm reactors, with a focus on nitrifying trickling filters (NTFs) for the treatment of wastewater. READ MORE

  5. 3. Biofilms in Nitrogen Removal - Bacterial Population Dynamics and Spatial Distribution

    Author : Robert Almstrand; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; AOB; NOB; biofilms; image analysis; FISH; Nitrosomonas; population dynamics; spatial distribution;

    Abstract : Efficient nitrogen removal at wastewater treatment plants (WWTPs) is necessary to avoid eutrophication of recipient waters. The most commonly used approach consists of aerobic nitrification and subsequent anaerobic denitrification resulting in the release of dinitrogen gas into the atmosphere. READ MORE
