16. Application of aerobic granular sludge for municipal wastewater treatment - Process performance and microbial community dynamics under fluctuating conditions
Sammanfattning : Pressures of growing cities, competition for use of urban areas and higher influent loads, are pushing for innovative technologies for wastewater treatment with low demands for land footprint and costs. Furthermore, wastewater treatment is needed to move towards a circular economy by harvest of valuable resources such as nutrients and energy. LÄS MER
17. Characterization of Bacterial Biofilms for Wastewater Treatment
Sammanfattning : Research performed at the Division of Environmental Microbiology has over the last years resulted in the isolation of possible bacterial key-organisms with efficient nutrient removal properties (Comamonas denitrificans, Brachymonas denitrificans, Aeromonas hydrophila). Effective use of these organisms for enhanced nutrient removal in wastewater treatment applications requires the strains to be retained, to proliferate and to maintain biological activity within theprocess.

18. Monitoring Wastewater Treatment Systems
Sammanfattning : This work considers various techniques to extract information from the vast amount of data collected at a modern wastewater treatment plant. If the information extracted is to be considered reliable is highly dependent on the data screening. Data screening includes validation and quality improvement of data. LÄS MER
19. On-site wastewater treatment : Polonite and other filter materials for removal of metals, nitrogen and phosphorus
Sammanfattning : Bed filters using reactive materials are an emerging technology for on-site wastewater treatment. Chemical reactions transfer contaminants from the aqueous to the solid phase. Phosphorus is removed from domestic wastewater by sorption to filter materials, which can then be recycled to agriculture as fertilisers and soil amendments. LÄS MER
20. Indigenous microalgae-activated sludge cultivation system for wastewater treatment
Sammanfattning : The municipal wastewater is mainly composed of water containing anthropogenic wastes that are rich in nutrients such as carbon, nitrogen and phosphorous. The cost for biological treatment of wastewater is increasing globally due to the population growth in urban cities. LÄS MER
