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

2. Investigation of a Biofilm Reactor Model with Suspended Biomass
Abstract : Biofilms are compact, sessile microbial communities that attach to surfaces in aqueous environments. In wastewater treatment, they are especially important for removal of phosphorus and nitrogen, which, if released into a receiving water body, can cause severe eutrophication. READ MORE

3. The deammonification in Moving Bed Biofilm Reactors
Abstract : Deammonification process appears to be a good alternative to treat reject water. In this thesis, control strategies were studied at pilot scale in order to optimise the deammonification process operated in a Moving Bed Biofilm Reactor (MBBR) for reject water treatment. READ MORE

4. Reactors and biosensors for improved microbial degradation of acetonitrile
Abstract : Biodegradation is becoming an attractive mode of operation for eliminating toxic chemicals released from industrial processes or already present in the environment. One needs, however, not only to identify organisms capable of degrading such chemicals, but also to address the issue of whether these chemicals, after being degraded, will be toxic to the degrading organisms if present in high concentrations.

5. Dynamic Modeling of Nitrifying Trickling Filters
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
