1. Biofilms in Nitrogen Removal - Bacterial Population Dynamics and 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

2. Bioassays for the determination of nitrification inhibition
Abstract : Requirements for nitrogen reduction in wastewater treatmentplants were introduced in Sweden in the early 1990s. Thiswas a governmental move to reduce the nitrogen discharges tothe Baltic and Kattegatt in order to prevent eutrophication.The nitrification process in wastewater treatment plants isperformed by nitrifying bacteria.

3. Nitrifyers in constructed wetlands treating landfill leachates
Abstract : Landfill leachate is produced many years after a landfill site closes. Hence, treatment by “natural methods”, as e.g. constructed wetlands, with low management requirements is attractive. READ MORE

4. 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
