11. Effects of ozonated sewage effluents and pharmaceuticals in zebrafish (Danio rerio)
Sammanfattning : The aquatic environment is the main destination for many organic pollutants originating from human activity. Pharmaceuticals are significant contributors to this pollutant cocktail. LÄS MER
12. Degradation of organic matter in wastewater -Enhanced denitrification and removal of refractory organics
Sammanfattning : Degradation of organic matter takes place in many processes within a wastewater treatment plant (WWTP). The need for optimisations and extended degradation processes for both organics and nitrogen will increase as outlet demands are strengthened and increasing loads are desired. LÄS MER
13. Treatment of Textile Wastewater by Combining Biological Processes and Advanced Oxidation
Sammanfattning : Treatment of textile wastewater is challenging because the water contains toxic compounds that have low biodegradability. Dyes, detergents, surfactants, biocides and more are used to improve the textile process and to make the clothes resistant to physical, chemical and biological agents. LÄS MER
14. Development of Mild Methods for Selective Covalent Functionalization of Graphene
Sammanfattning : This thesis discusses methods for the comparatively mild covalent functionalization of graphene. Several graphene models were investigated: polycyclic aromatic hydrocarbons (PAHs), chemical vapor deposition (CVD)-graphene on SiO2/Si substrate, graphite foil, graphite flakes, kish graphite and highly oriented pyrolytic graphite.

15. Exploring the role of granular activated carbon in drinking water production
Sammanfattning : Safe and clean drinking water is recognised as a human right by the United Nations, but water sources world-wide are affected by the widespread use of synthetic chemicals, creating a challenge that drinking water producers must address. Many of these synthetic chemicals, here referred to as organic micropollutants (OMPs), are not well removed by conventional drinking water treatment, and thus additional treatment steps are needed.
