1. Functionalization of Synthetic Polymers for Membrane Bioreactors
Sammanfattning : Membrane bioreactors (MBRs) show great promise for productivity improvement and energy conservation in conventional bioprocesses for wastewater reclamation. In order to attain high productivity in a bioprocess, it is crucial to retain the microorganisms in the bioreactors by preventing wash out. LÄS MER
2. Concepts for improving ethanol productivity from lignocellulosic materials : encapsulated yeast and membrane bioreactors
Sammanfattning : Lignocellulosic biomass is a potential feedstock for production of sugars, which can be fermented into ethanol. The work presented in this thesis proposes some solutions to overcome problems with suboptimal process performance due to elevated cultivation temperatures and inhibitors present during ethanol production from lignocellulosic materials.

3. Pharmaceutical compounds; a new challenge for wastewater treatment plants
Sammanfattning : Analytical analyses conducted at the Himmerfjärden WWTP (285.000 PE connected) identified 70 pharmaceutical compounds belonging to different therapeutic classes. Such organic micropollutants at low detected concentration range of µg - ng l-1 did not affect the treatment processes at WWTP. LÄS MER
4. Comparative study on different Anammox systems
Sammanfattning : The legal requirements for wastewater discharge into environment, especially to zones exposed to eutrophication, lately became stricter. Nowadays wastewater treatment plants have to manage with the new rules and assure better biogenic elements’ removal, in comparison with the past. LÄS MER
5. Comparative analysis of pathogen occurrence in wastewater : management strategies for barrier function and microbial control
Sammanfattning : This project was initiated to fill knowledge gaps on the occurrence of pathogens in different streams of wastewater, e.g. greywater and domestic wastewater. LÄS MER
