11. Enhanced Biological Phosphorus Removal -Processes, Competing Substances and Tools for Operation of Wastewater Treatment Plants
Sammanfattning : The idea of phosphorus removal at wastewater treatment plants is to transfer dissolved phosphorus into a solid phase. Together with the rest of the produced sludge it is then removed from the water, resulting in a decreased concentration of phosphorus in the effluent and the prevention of the eutrophication in the recipient.

12. Sound, Light and Electricity : as applications and analysis techniques to study metabolic effect and biofilm characterization of Geobacter sulfurreducens
Sammanfattning : ElectricityBio-electrochemical systems such as microbial fuel cells (MFCs) and microbial electrolysis cells have shown promise in wastewater treatment, bioremediation, desalination, carbon sequestration and as an alternative, renewable energy source. MFCs produces electricity via anaerobic oxidation of substrates with the subsequent extracellular electron transfer to an electrode. LÄS MER
13. Change of toxicity during secondary treatment of industrial sludge containing nitroaromatics
Sammanfattning : Wastewater treatment plants in Sweden are facing a great challenge due to the prohibition of depositing organic waste which gained legal force in January 2005. Biological and commercial available alternatives to disposal are composting and anaerobic digestion. LÄS MER
14. Microbial Phosphorus Removal in Waste Stabilisation Pond Wastewater Treatment Systems
Sammanfattning : Waste Stabilisation Ponds (WSPs) are characterised by low phosphorus (P) removal capacity. Heterotrophic bacteria are principal microbial agents in WSPs in addition to algae. LÄS MER
15. Start-up and operational strategies for deammonification plants : - a study with one-stage moving bed biofilm reactors treating reject water
Sammanfattning : To limit eutrophication, wastewater treatment plants use biological methods to convert degraded nitrogen to nitrogen gas. Deammonification, or partial nitritation in combination with anammox, has been shown to be an energy efficient process. LÄS MER
